Car Magnet Design Guide: What Should Go on a Vehicle Magnet?

A strong vehicle magnet should help people identify your business, understand your service and remember how to contact you without needing to read a crowded advertisement.

A business vehicle can create repeated exposure throughout the day. It may be seen while driving through a neighbourhood, parked outside a customer’s property, stopped near a job site or sitting in a business parking lot. A well-designed car magnet turns that visible space into a reusable advertising surface.

The design still needs to work within a limited amount of time. Most people will only see the vehicle briefly, so the magnet cannot depend on long paragraphs, complicated service lists or small contact information. The message needs to remain clear whether the vehicle is moving slowly, parked nearby or viewed from across a parking lot.

Pryntco’s custom car magnet printing is available in 12" × 18" and 18" × 24" sizes. The best option depends on the available vehicle space, amount of information and viewing distance.

What Is a Business Car Magnet?

A business car magnet is a removable printed sign designed to attach to a compatible metal vehicle surface. It can display the business name, logo, service category and contact information while allowing the graphic to be removed or transferred when necessary.

Businesses may use vehicle magnets to:

1. Build local brand recognition
2. Advertise while travelling between appointments
3. Identify service vehicles at customer properties
4. Promote a phone number or website
5. Brand personal vehicles used for occasional business travel
6. Create consistent identification across several vehicles
7. Support seasonal or temporary promotions

Car magnets are especially useful when permanent vehicle graphics are not appropriate. The vehicle may be leased, shared between personal and business use or only require branding during working hours.

Begin With One Clear Goal

Before deciding what to place on the magnet, determine what the advertisement needs to accomplish.

The goal may be to:

1. Make the business name more recognizable
2. Generate phone calls
3. Send people to the company website
4. Identify the service being performed nearby
5. Promote one specific product or service
6. Show that the business serves a local area

The goal should guide the information hierarchy. A magnet intended to generate phone calls needs a highly visible phone number. A magnet focused on brand awareness may place greater emphasis on the company name and service category.

Trying to accomplish several unrelated goals on one small magnet can make the design difficult to understand.

Design for a Short Viewing Time

A brochure can be held and read carefully. A vehicle magnet may only be visible for a few seconds.

The main information should be understandable during a quick glance. That normally means limiting the design to:

1. The business name or logo
2. A short service description
3. One primary contact method
4. An optional website or service area

Additional details can appear on the website, business card or sales materials. The vehicle magnet should introduce the business rather than explain every service it provides.

Include the Business Name

The business name should be one of the most noticeable elements. People need to know which company the vehicle represents before they can remember or search for it later.

The name should:

1. Use the correct spelling
2. Match the name used on the website and other materials
3. Remain readable at the final printed size
4. Stand apart from the background
5. Not be hidden inside a complicated logo

When the logo contains very small wording, consider displaying the main business name separately. A detailed logo may look clear on a computer screen but become difficult to recognize from several metres away.

Explain What the Business Does

A business name does not always explain the service. The magnet should include a short category or description when the company name could be unclear to someone seeing it for the first time.

Examples include:

1. Residential Cleaning
2. Plumbing and Drain Services
3. Mobile Car Detailing
4. Landscaping and Lawn Care
5. Painting and Renovations
6. Real Estate Services
7. Heating and Cooling
8. Delivery and Moving Services

Keep the description direct. Clever slogans should not replace the basic explanation of what the company provides.

Use One Main Service Message

Many businesses offer several services, but a vehicle magnet should not automatically list all of them.

A long list can force the text to become smaller and reduce the visibility of the phone number or business name. Instead, choose one broad service category or the service most important to the campaign.

For example, a contractor may use “Home Renovations” instead of listing kitchens, bathrooms, basements, flooring, drywall, painting and carpentry individually.

The website can provide the complete service list after the customer remembers the company or visits the page.

Choose One Primary Contact Method

The magnet should make it clear how potential customers can reach the business.

The primary contact method may be:

1. A phone number
2. A short website address
3. A memorable business name customers can search

Choose the method the business actively monitors. A phone number is useful when calls are important to the sales process. A website may work well when customers need to view services, photographs or appointment options first.

Do not make every contact method equally prominent. A phone number, website, email address, social handle and QR code competing in the same small space can make the design crowded.

Make the Phone Number Easy to Read

When calls are the main goal, the phone number should be large enough to recognize without standing directly beside the vehicle.

Use:

1. A simple, readable font
2. Strong contrast against the background
3. Consistent spacing between number groups
4. A size appropriate for the magnet

Avoid placing the phone number over a detailed photograph or using thin lettering that may disappear from a distance.

Proofread every digit carefully. A single incorrect number can direct potential customers somewhere else and make the entire order unusable.

Keep the Website Address Short

A website can be useful when the address is simple enough to remember or read quickly.

Normally, the design does not need to include:

1. https://
2. www. when the website works without it
3. A long internal page address
4. Tracking parameters

Use the shortest accurate version that leads customers to the business. Long addresses with several words, symbols or folders may be difficult to remember after the vehicle has passed.

Should a Vehicle Magnet Include a QR Code?

A QR code is usually less important on a vehicle magnet than it is on a brochure, flyer or countertop sign. People should never be encouraged to scan a code while driving.

A code may be useful when:

1. The vehicle is normally parked at job sites
2. The magnet is large enough for a properly sized code
3. The code has strong contrast and clear space around it
4. The destination directly supports the advertisement

Even then, the business name and contact information should remain readable without scanning anything.

Do not make the QR code the only way to identify or contact the company. It may be blocked by glare, viewed from too far away or seen while the vehicle is moving.

Add the Service Area Only When It Helps

Local service businesses may benefit from including the main city or region they serve.

Examples include:

1. Serving Hamilton and Area
2. Toronto Mobile Service
3. Serving the Greater Toronto Area
4. Local Service in Your Neighbourhood

Keep the wording accurate. Do not list several distant locations if the company cannot realistically provide service throughout those areas.

The location should support the main message without becoming larger than the business name or contact method.

Use a Simple Information Hierarchy

Information hierarchy determines what people notice first, second and third.

A practical vehicle-magnet hierarchy may be:

1. Business name or logo
2. Main service category
3. Phone number or website
4. Optional service area or short benefit

Not every element should have the same size and visual weight. The most important information should be larger and more prominent.

When every line is bold, brightly coloured and oversized, the viewer may not know where to begin.

Limit the Number of Words

Vehicle graphics need to communicate faster than most printed marketing materials. Long sentences and detailed descriptions are unlikely to be read from another vehicle or across a parking lot.

Remove wording that does not directly help the viewer understand:

1. Who the company is
2. What it provides
3. How to contact it

A simple design with ten useful words may perform its job more effectively than a design containing fifty words in very small text.

Avoid Long Lists of Services

A service list may appear helpful during the design process, but it often becomes unreadable on the vehicle.

Instead of listing:

1. Interior painting
2. Exterior painting
3. Drywall repair
4. Cabinet painting
5. Deck staining
6. Wallpaper removal

The magnet may simply say:

Residential and Commercial Painting

The broader category is easier to understand and allows the contact information to remain visible.

Use Readable Fonts

Typography plays a major role in whether the magnet can be understood quickly.

Choose fonts that:

1. Have clear letter shapes
2. Remain readable in uppercase and lowercase
3. Do not become too thin when printed
4. Match the company’s branding
5. Create clear differences between headings and supporting text

Decorative scripts may work for a short logo accent, but they are usually less suitable for phone numbers, websites and service descriptions.

Review the design at its actual printed dimensions. Text that looks large while zoomed in may become much smaller on the finished magnet.

Use Strong Colour Contrast

The design needs enough contrast to remain visible against both the magnet background and the vehicle colour.

Useful combinations may include:

1. Dark text on a light background
2. White text on a dark background
3. A solid colour block behind the phone number
4. A simple border separating the magnet from the vehicle

Avoid:

1. Light grey text on white
2. Dark blue text on black
3. Thin text over a detailed photograph
4. Several similar shades with little separation

The design should still be recognizable under sunlight, shade and ordinary parking-lot lighting.

Consider the Colour of the Vehicle

The vehicle colour becomes part of the final presentation. A white magnet placed on a white vehicle may blend into the door unless the design includes a strong border or background.

A dark magnet on a black vehicle may have the same problem.

Before approving the design, consider:

1. The vehicle’s exterior colour
2. The location where the magnet will be placed
3. Whether a border is needed
4. Whether the main colours remain visible
5. Whether the background creates enough separation

A design shown on a neutral computer screen may look different once placed on the actual vehicle.

Use the Logo Carefully

The logo should help people identify the company, but it should not consume all the available space.

A logo containing several small details, taglines or fine lines may need to be simplified for the vehicle format. The main name or symbol should remain recognizable without requiring close inspection.

Use an original vector or high-resolution logo file whenever possible. Enlarging a small logo copied from a website can produce blurred edges and unclear lettering.

Decide Whether an Image Is Necessary

Some vehicle magnets benefit from a simple product or service image. Others communicate more clearly with typography and branding alone.

An image may help when:

1. The service can be recognized immediately
2. The image supports the headline
3. There is enough room for the business name and contact information
4. The photograph remains clear at the final size

A car-detailing business may use a clean vehicle image. A landscaping company may show a finished yard. A food business may show one recognizable product.

Do not add several photographs to a small magnet. Multiple images can reduce the available space and make the design feel like a miniature flyer.

Avoid Photographs With Too Much Detail

Detailed backgrounds can make text difficult to read and may not remain clear from a distance.

When using a photograph:

1. Select one clear subject.
2. Use a high-resolution original.
3. Place text over a solid or simplified area.
4. Avoid covering the main subject with contact information.
5. Check that the image still makes sense after cropping.

A solid colour background with strong typography is often more effective than an image that requires viewers to study the design.

Choose the Appropriate Car Magnet Size

Pryntco offers car magnets in 12" × 18" and 18" × 24" sizes. The appropriate size depends on the available flat surface and the amount of information included.

A 12" × 18" magnet may work when:

1. The design contains a short business name
2. Only one service and contact method are included
3. The vehicle has limited flat door space
4. The magnet is mainly used for identification

An 18" × 24" magnet may work when:

1. The vehicle has a larger compatible surface
2. Greater visibility is needed
3. The logo requires more room
4. The design includes a service description and larger phone number

Measure the intended vehicle area before ordering. Do not choose a size based only on the digital design preview.

Measure the Vehicle Before Finalizing the Design

Vehicle doors contain handles, body lines, trim, curves and gaps that may reduce the usable area.

Measure:

1. The width of the flat panel
2. The height between body lines and trim
3. The distance from the door handle
4. The space before the door edge
5. Any area affected by curves or moulding

The magnet should sit completely on a flat compatible surface. It should not cross door gaps, sharp body lines, moulding or highly curved areas.

Confirm That the Vehicle Surface Is Magnetic

Not every vehicle panel is made from magnetic steel. Some panels may use aluminum, composite material, fibreglass or other non-magnetic construction.

Test the intended area before ordering. A small ordinary magnet can help confirm whether the specific panel accepts magnetic material.

Test the exact door or panel where the finished graphic will be placed. One part of the vehicle may be magnetic while another part is not.

Choose a Flat Placement Area

The magnet needs full contact with the vehicle surface. Placing it over curves, creases, rust, trim or damaged paint can reduce contact and create lifted edges.

Suitable placement areas are generally:

1. Flat
2. Clean
3. Dry
4. Free from rust and loose paint
5. Large enough for the complete magnet

Do not fold the magnet around a corner or force it across a body line. The entire back surface should sit evenly against the panel.

Use Matching Magnets on Both Sides

Many businesses order a pair so the advertisement appears on both sides of the vehicle.

Using matching magnets can improve visibility from either direction and create a more complete presentation.

Before ordering, confirm that both sides have enough compatible space. Vehicle fuel doors, body shapes or trim may create different placement conditions on each side.

The artwork may remain the same on both magnets, but the positioning should be tested separately.

Keep Branding Consistent Across Multiple Vehicles

Businesses with several service vehicles should use a consistent layout so customers recognize the fleet as part of the same company.

Keep these elements consistent:

1. Logo size and placement
2. Brand colours
3. Service wording
4. Phone number
5. Website address
6. Typography

The vehicle models and available spaces may differ, so the design may need size adjustments. The overall identity should still remain recognizable.

Match the Magnet to Other Business Materials

The car magnet should look connected to the company’s business cards, uniforms, signs, website and other printed materials.

Consistent branding helps customers recognize the company after seeing it in several places.

Pryntco’s large-format printing and sign products include vehicle magnets, Coroplast signs, banners, posters, event displays and other options that can support a coordinated visual identity.

Prepare the Artwork at the Correct Size

The design should be created at the exact dimensions being ordered. Resizing completed artwork at the last moment can affect proportions, spacing and image quality.

Before beginning, confirm:

1. The selected magnet size
2. Landscape orientation
3. The required safe area
4. The expected viewing distance
5. The vehicle colour
6. The intended placement area

Build the design around the final format instead of adapting a business card, flyer or social media graphic without reconsidering the layout.

Keep Important Content Inside the Safe Area

Logos, phone numbers and other essential elements should remain comfortably inside the edges.

Do not place important content directly against the border. Leaving space around the wording helps prevent the design from feeling crowded and keeps the message clear.

Background colours and images should extend correctly according to the product’s artwork requirements, while essential content remains protected.

Use High-Resolution Artwork

Vehicle magnets are viewed at a larger physical size than business cards or many digital graphics. Low-resolution images may become noticeably blurred or pixelated.

Avoid using:

1. Website screenshots
2. Images saved from social media
3. Small logos enlarged significantly
4. Photographs sent through heavily compressed messaging apps
5. Graphics containing visible watermarks

Use original image and logo files whenever possible.

Pryntco’s guide to preparing artwork for professional printing explains resolution, colour, fonts, file size and final artwork setup in more detail.

Review the Design at Actual Size

A design may look balanced while displayed small on a computer screen. At full size, the logo may feel too large, the phone number may be too small or the spacing may appear uneven.

Review the artwork at its intended dimensions and from a reduced screen view that simulates seeing it from farther away.

Ask another person to look at the design briefly, then explain what they noticed. They should be able to identify the business type and main contact method without studying the layout.

Proofread Every Detail

Vehicle advertising may be seen repeatedly over a long period, making accuracy especially important.

Check:

1. Business name
2. Service description
3. Phone number
4. Website address
5. Service area
6. Spelling and punctuation
7. Licence or professional information when required

Call the phone number, type the website address and confirm that every detail is current before approving production.

Clean the Vehicle Before Applying the Magnet

The intended surface should be clean and dry before the magnet is installed. Dirt, moisture and debris can prevent full contact and may affect the surface underneath.

Before placement:

1. Wash the intended panel.
2. Remove dirt, dust and road residue.
3. Dry the surface completely.
4. Clean and inspect the back of the magnet.
5. Confirm that the panel remains smooth and undamaged.

Place the magnet carefully and smooth it so the full back sits evenly against the vehicle.

Inspect the Magnet Regularly

A removable vehicle magnet should not be treated as something that can be installed once and ignored indefinitely.

Regularly:

1. Remove the magnet.
2. Clean the vehicle surface.
3. Clean and dry the back of the magnet.
4. Check the edges for damage or lifting.
5. Reapply it to a clean, dry panel.

Regular inspection helps identify trapped dirt, moisture or damaged edges before they create a larger problem.

Remove the Magnet Before Automatic Car Washing

Remove the magnet before taking the vehicle through an automatic car wash. Brushes, water pressure and drying equipment may lift, bend or remove it.

Clean the magnet separately and allow both the magnet and vehicle surface to dry completely before reapplying it.

Also inspect the magnet after severe weather, long trips or any situation that could affect its position.

Store the Magnet Flat

When the magnet is removed, store it clean and flat. Folding or sharply bending it can affect how evenly it sits on the vehicle later.

Avoid placing heavy objects on top of it or leaving it against dirty surfaces. Keep the printed face protected from scratches and the magnetic side free from debris.

Car Magnets for Home-Service Businesses

Home-service businesses can use vehicle magnets to identify themselves while travelling between jobs and while parked at customer properties.

Suitable information may include:

1. The company name
2. The main service category
3. A phone number
4. A short website
5. The primary service area

Examples include cleaners, painters, landscapers, contractors, movers, plumbers, electricians and maintenance companies.

The service description should be clear enough that nearby homeowners understand why the vehicle is present.

Car Magnets for Mobile Businesses

Mobile businesses often provide their service at a customer’s home, office or event location. The vehicle itself is an important part of the customer experience.

Vehicle magnets can support:

1. Mobile detailing
2. Pet grooming
3. Photography
4. Catering
5. Delivery services
6. Repair services
7. Personal training

The magnet can help customers recognize the arriving vehicle while also promoting the business to nearby people.

Car Magnets for Real Estate Professionals

Real estate professionals may use removable magnets when travelling to showings, open houses and community events.

The design may include:

1. The agent’s name
2. Brokerage information
3. A professional photograph
4. Phone number
5. Website
6. A short real estate service description

Keep the portrait and logo balanced so the contact information remains readable. A photograph should not force the phone number into small text.

Car Magnets for Delivery and Event Businesses

Delivery, catering and event companies can use vehicle magnets to identify the business while arriving at customer locations.

The design may focus on:

1. The company name
2. The main product or service
3. A memorable website
4. A phone number
5. A simple brand image

These businesses may also use matching signs, banners and event displays to create a consistent presentation after arriving at the location.

Common Car Magnet Design Mistakes

One common mistake is treating the magnet like a small flyer and filling it with information that cannot be read from a normal viewing distance.

Other mistakes include:

1. Using a business name without explaining the service
2. Listing too many services
3. Making the phone number too small
4. Using a complicated script font
5. Placing thin text over a detailed photograph
6. Using colours that blend into the vehicle
7. Adding several contact methods with equal importance
8. Making a QR code the only response method
9. Using a low-resolution logo
10. Ordering before measuring the vehicle
11. Assuming every vehicle panel is magnetic
12. Placing the magnet over curves, trim or damaged paint
13. Failing to clean the surface before installation
14. Leaving the magnet attached during an automatic car wash
15. Not checking the phone number before printing
