How to orderSpecifications
Custom Magnetic Car Door Signs run on a 30 mil flexible magnetic sheet printed with full-color UV ink. They're sized for sedan, SUV, and crossover door panels and stick to steel body panels without adhesive. No residue, no tools, and no installation.
- Material
- 30 mil flexible magnetic sheet (removable, no adhesive).Grips steel doors, trunks, and hoods. Does not work on aluminum, fiberglass, or plastic panels.
- Print Method
- Direct UV print, ink bonded to the magnetic surface and cured instantly under UV light.Gives a scratch-resistant, waterproof finish that holds up through repeated removal and reapplication.
- Color Output
- CMYK full-color (the 4-color process using cyan, magenta, yellow, and black).Reproduces logos, photos, and text in bold, accurate color across the full sign face.
- Finishing
- Straight or rounded corners available.Rounded corners prevent edge lifting at highway speeds and are the better choice for vehicle use.
- Size Range
- Custom sizes available. Typical car door sizes run 12x18 in for compact sedans up to 18x24 in for SUV and crossover panels.Order the size that fits your specific door panel.
- Indoor/Outdoor Rating
- Rated for outdoor use. UV-printed surface resists rain and sun, holding up 2 to 3 years with weekly removal and cleaning.
- Single/Double-Sided
- Single-sided only. Order 2 signs, one per door, for both driver and passenger side coverage.
- Thickness
- 30 mil (roughly 0.75 mm). Thick enough to maintain flat contact and resist wind lift at speeds up to roughly 65 mph on a clean, dry surface.

- Direct UV Print Built for Car Door Panels
- Apply, Remove, and Reapply Without Tools
30 Mil Magnetic Sheet With Rounded Corners
The 30 mil flexible magnetic sheet (thicker than a standard refrigerator magnet at roughly 17 mil) holds flat against steel car door panels at highway speeds. Rounded corners remove the sharp 90-degree edge that catches wind and starts to lift. And that difference matters: square-cornered signs peel from the edge first, then lose grip entirely at speed. A2Z Printing Hub cuts every car door sign with rounded corners by default so road loss stays off your list of worries.
Direct UV Print Built for Car Door Panels
UV print bonds ink directly to the magnetic surface, then cures it instantly under UV light for a scratch-resistant, waterproof finish. Rain, sun, and repeated removal cycles do not crack or fade the color. You get crisp, bold graphics that hold up through 2 to 3 years of weekly use. Worth knowing: this is not a laminated print. The ink cures into the surface itself, so there is no film layer to bubble or peel.
Apply, Remove, and Reapply Without Tools
No adhesive, no tools, no installation time. Put the sign on before your first job and take it off before dinner. The same sign reattaches hundreds of times across its lifespan without losing grip or leaving residue. Removability in seconds. That's the entire point.
Customer reviews
Ideal for
Not the best fit for
Vehicles with aluminum, fiberglass, or plastic body panels won't hold a magnet. Custom Vehicle Decals use adhesive that bonds to any smooth surface.
Business owners who want branding that stays on 24 hours a day for 3 to 5 years without removal are better served by Custom Vehicle Decals.
Bumper, hood, or heavily curved panel placement won't let the magnetic sheet lie flat. Custom Vehicle Decals handle curved surfaces with adhesive conformability.
How to choose
Use these buying points to choose the right Custom Magnetic Car Door Signs configuration.
-
Matching the Sign Size to Your Car Door Panel
Measure your door panel first. Run a tape from the door handle to the nearest body crease, then from the window line down to the door bottom. Most sedan doors fit a 12x18 in sign comfortably.
Most SUV and crossover doors hold an 18x24 in sign without crowding the handle or crease. Keep your design at least 0.5 in from all edges so no text sits near the cut line.
-
Rounded Corners Over Straight Corners for Vehicle Use
Here's the thing: straight corners work fine on a flat indoor surface. On a car door at 60 mph, the 90-degree edge catches airflow and starts to lift. Rounded corners remove that sharp edge entirely, which is why every sign going on a vehicle should use them. Straight corners are the wrong call for road use, full stop.
-
Magnetic Car Door Sign Versus Permanent Vehicle Decal
The short answer is this: the sign type follows your situation, not your preference.
-
Choose the magnetic sign when:
Your vehicle is leased, you drive personal routes after work, or you want to test a message before committing. The 30 mil magnetic sheet peels off in seconds and leaves zero residue, so you're not locked into anything.
-
Choose Custom Vehicle Decals when:
Your panels are aluminum, fiberglass, or plastic (where a magnet won't grip), or your branding stays on the vehicle 24 hours a day for 3 to 5 years. Adhesive vinyl bonds to any smooth surface and doesn't need weekly removal.
-
Single Sign Versus a Matched Pair for Both Doors
One sign on the driver door covers roughly half of passing traffic. Order 2 matching signs (one per door) and your business name reads from both sides. That said, if budget is the constraint right now, start with the driver side and add the passenger sign on your next order. The sizing and color output will match across runs.
Pair it with
Permanent Alternative for Non-Steel Panels
Your car door sign grips steel. But aluminum bodies, fiberglass bumpers, and plastic trim won't hold a magnet. Custom Vehicle Decals use adhesive that bonds to any smooth surface and last 3 to 5 years without removal.
Larger Vehicle Variants
A car door panel runs roughly 12x18 to 18x24 in. Service vans and pickup trucks carry bigger flat surfaces that need bigger signs. Match the format to the vehicle.
Job Site Ground-Level Branding
Your door sign brands the vehicle in the driveway. An A-Frame Sign at the curb or entrance carries the same logo and phone number at eye level for every neighbor walking past.
Storefront and Event Match
Customers who spot your car on the road recognize the same logo at your booth or location. Bold color. Same message. Consistent across every surface.
FAQs
Get your artwork right
We accept PDF, AI, PNG, and JPG files. AI (vector format) is the better choice for logos because it scales without softening edges. Minimum 150 DPI at final print size, 300 DPI recommended for anything under 18 in wide, where viewers get close enough to spot a soft edge.
- Color mode
- Set your color mode to CMYK (the 4-color printing process using cyan, magenta, yellow, and black) before exporting. RGB is a screen color model and shifts when converted to print, so colors can come out warmer or cooler than expected.
- Bleed
- Add 0.25 in bleed on all sides. Keep all text and logos at least 0.5 in from the cut line. For rounded corners, keep critical content at least 0.5 in from each corner as well.
- Bleed
- The magnetic sheet background is white by default. Full-bleed color is available, but a slight white edge may show if the cut shifts by a fraction. And if you don't have a ready file, use our free online design tool or our professional design service.

How to Order
- Pick your size (standard or custom), choose straight or rounded corners, and upload your design file or use the free online design tool.

- Signs ship flat in rigid mailers to prevent curl. Each order ships with a care instruction card.
Production and Shipping Timeline
**Standard production:** 1 to 2 business days after proof approval.
**Fleet orders:** 10 or more signs may add 1 to 2 production days. Volume discounts apply automatically at 10 or more signs.
Signs ship flat. Rolling causes permanent curl that weakens road grip, so we don't do it. Matched pairs (driver door plus passenger door) ship together in one mailer.
Order before 12 PM EST and your signs go into production the same day. Bulk orders of 10 or more qualify for volume pricing.

Care instructions
Product care
- Remove the sign from the vehicle at least once a week. Wipe both the magnetic backing and the door panel with a damp cloth to clear dirt and grit. Trapped particles between the magnet and paint cause scratches. The magnet itself does not.
- Never slide the sign across the paint. Lift it straight off the panel. Before any automatic car wash, take the sign off entirely. Brush arms catch the edge at speed and can tear it free.
- Store the sign flat on a steel surface (a file cabinet works) or between two flat boards. Do not roll or fold it. Rolling causes a permanent curl that bows the sign away from the door panel and weakens grip at highway speeds.
