1. Why Choose Custom Car Magnets?


Custom car magnets can be used for various purposes, including business advertising, personal expression, event promotion, and more. They are suitable for cars, trucks, vans, and even refrigerators or metal doors.

Cost-Effective Advertising

Compared to other forms of mobile advertising, car magnets are highly affordable. They offer excellent value for money, allowing businesses to promote their brand without a significant investment.

Easy to Use

Car magnets are easy to apply and remove, making them ideal for temporary promotions or changing messages frequently. They leave no residue and do not damage the vehicle’s paint.


High-quality car magnets are weather-resistant and can withstand exposure to the elements, including rain, sun, and wind, ensuring your message stays visible for a long time.


2. Designing Your Custom Car Magnet

Choosing the Right Size

Select a size that fits well on your vehicle and allows your message to be easily readable. Common sizes include 12” x 18”, 12” x 24”, and 18” x 24”. Measure the available space on your vehicle to ensure a good fit.

Effective Design Tips

  • Keep It Simple: Use clear and concise messaging. Too much information can be overwhelming and hard to read.
  • Bold Fonts and Colors: Choose fonts and colors that are easily readable from a distance. High contrast between text and background is crucial.
  • Include Contact Information: Ensure your phone number, website, or social media handles are prominently displayed.
  • Use High-Quality Images: If incorporating images or logos, use high-resolution files to avoid pixelation.

Design Tools

Use graphic design software like Adobe Illustrator, Photoshop, or online tools like Canva to create your design. Many printing services also offer design assistance if needed.


3. Materials and Printing Options

Magnetic Material

Car magnets are typically made from a flexible magnetic sheet that adheres securely to metal surfaces. Look for high-quality materials that offer strong magnetic adhesion and weather resistance.

Printing Technology

  • Digital Printing: Provides vibrant colors and sharp details, ideal for complex designs and photographs.
  • UV Printing: Uses ultraviolet light to cure the ink, resulting in durable and fade-resistant prints.

Finishing Options

  • Glossy Finish: Offers a shiny and vibrant appearance, making colors pop.
  • Matte Finish: Provides a non-reflective surface, reducing glare and giving a sophisticated look.


4. Applying and Maintaining Car Magnets

Application Steps

  1. Clean the Surface: Ensure the vehicle’s surface is clean and dry. Dirt and moisture can reduce magnetic adhesion.
  2. Position the Magnet: Place the magnet on a flat, smooth surface of the vehicle. Avoid placing it over curves or creases.
  3. Smooth Out Air Bubbles: Start from the center and smooth outwards to remove any air bubbles and ensure full contact with the surface.

Maintenance Tips

  • Remove Regularly: Remove the magnet weekly to clean the surface and the back of the magnet to prevent dirt buildup.
  • Store Flat: When not in use, store the magnet flat to avoid warping or damage.
  • Avoid High Speeds: Remove the magnet before washing the vehicle or driving at high speeds to prevent loss or damage.


5. Best Practices for Using Car Magnets

Strategic Placement

Place your car magnet on a flat, highly visible area of the vehicle. Both doors and the rear of the vehicle are common spots.

Regular Updates

If using car magnets for advertising, consider updating the design periodically to keep your message fresh and engaging.

Compliance with Regulations

Ensure that your car magnet complies with any local regulations regarding vehicle signage, especially if used for commercial purposes.

File Setup

In order to ensure your files are print-ready, we recommend that you upload them in PDF format. When you generate a print-ready PDF, your computer will use the settings in Adobe Acrobat Distiller or any other PDF generating programs you may use. Please make sure that these are set properly before generating your PDF file.

If you are uploading PDF files created in Photoshop, please be sure all layers are flattened.

We also accept .JPG (JPEG), and .TIF (TIFF) file types, however PDF is the preferred format.

Check your file to make sure it meets our file creation guidelines. This will help speed up the production of your project and give your printed piece the best results.

  1. Use the CMYK colorspace (Cyan, Magenta, Yellow, blacK). These are industry standard printing colors. CMYK colors are different than RGB (Red, Green, Blue), which are used to display colors on your screen.
  2. Use a minimum resolution of 300 dpi for image files.
  3. Specify trim area with crop marks. (Don’t place crop marks inside the work area.)
  4. Artwork should have 1/8″ (0.125″) bleed extending past the trim line. This is to prevent minor cutting variations from leaving unintended results at the trim edge.
  5. Safe Area is the 1/8″ (0.125″) area inside the trim line. Do not put critical information or images within the Safe Area. This is to prevent minor cutting variations from leaving unintended results at the trim edge.
  6. If you want printed borders, they must be placed a minimum of 1/8″ (0.125″) inside the trim line and include bleed. This is to prevent minor cutting variations from leaving unintended results at the trim edge.
