How to Turn Your Car into a Book Mobile as a Self-Publisher

Since self-publishers don’t have the same funds as traditional publishers, you should always be on the lookout for ways to promote your book without breaking the bank. If you’re looking for inexpensive but effective way to advertise your new book, try a car magnet. You can turn your car or truck into a “Book Mobile” for about $40.

Car Magnets

Find a printing service that offers car magnets. These magnets are about 9 x 12 to 12 x 18 inches in size—they fit perfectly on the side of your car door.
Create the book advertisement in a standard book layout program (like InDesign, or even Microsoft Word). Keep the ad simple—all people need to see is the book cover, title, and maybe a short description of what it’s about. When you’re driving, all people are probably going to see is the title. When parked, people will have time

Position the book cover on the right-hand side of the magnet. Make it as large as the magnet’s dimensions will fit.

Type in a quick headline, preferably three to four words long, on the left side in large lettering. This will be the most difficult part, because it’s hard to summarize your book’s purpose in just a few words. Set the font to 72 point or higher—whatever size will fit the size of the magnet.

Type in your book’s website address or an 800 number across the bottom of the magnet so that people can contact you for more information. You may have to adjust the side of the book cover to allow room at the bottom.

Convert the document to PDF format or a TIF file (CMYK color mode) using an image editing program like Adobe Photoshop. Send or upload the PDF or TIF file to your printing service. Have 2 magnets printed—one for each side of your car. Now you’ve got a certified “Book Mobile!”


Some printing services allow you to design your magnet right on screen—just choose an overall format, add images, type in text, and make it all your own. This will save you the aggravation of having to lay the design out in a graphic design program and then convert it to PDF format.

Be sure to carry bookmarks and copies of your book in your car at all times in case someone asks you about the book while you’re driving around town.
