Car Magnet Sizes: Which Dimensions Work Best?

Custom car magnets offer a cost-effective and flexible solution for mobile advertising. They transform your car into a professional marketing tool in seconds and can be removed just as quickly. Ideal for small businesses, realtors, contractors, and nonprofits, they allow you to reach a wider audience without vehicle wraps. Plus, they keep your paint protected compared to permanent decals.

A successful car magnet design combines bold graphics, clear text, and strong contrast to catch the eye even at high speeds. Choose clean fonts and large logos so your message is readable from a distance. Include a clear call to action—like a phone number or website—and consider your vehicle’s curves to ensure a sleek fit. Waterproof, fade-resistant vinyl ensures your magnet stays vibrant through rain, sun, and car washes.

Clean the vehicle surface with mild soap and dry it before applying your magnet to ensure strong adhesion. Align the top edge first, then press firmly toward the bottom, smoothing out air bubbles. Avoid placing magnets over seams or curves that can reduce contact. To protect both the magnet and your paint, remove it periodically, clean underneath, and store it flat when not in use. This helps maintain optimal sticking power and shield your car’s finish.
