Truck Lettering Decals: Cut Letters vs Rectangular Decals

Truck lettering decals come in two common styles. One is a set of separate cut letters that sit directly on the paint. The other is a single rectangular decal with a background panel and the lines printed on it. Work Decals makes the second kind and does not make cut letters. Neither style is right for every truck, so this guide compares them honestly, starting with how each is applied.

The two styles

Cut letters are individual letters and numbers cut out of vinyl. They are held in place on a sheet of transfer tape, pressed onto the door, and the tape is then peeled away. Only the letters stay behind, so the door color shows between and around them.

A rectangular decal is one piece: a solid rectangle in a sticker color with the lines of text on it. Our decals are made from 3M and Oracal vinyl in widths of 12, 18 and 24 inches, with six sticker colors (White, Black, Yellow, Silver, Red and Blue) and four lettering colors. You see the result on a truck door preview in the door builder before you order.

How each is applied

Cut letters go on as a group, because the transfer tape keeps the spacing fixed. The job is getting the whole line level, and a long run of letters shows any tilt. Small loose pieces can also pull away from the tape. Many people hire a sign shop for this.

A rectangular decal has straight edges, so you can line it up with a strip of masking tape and a tape measure. The method is the same as for any decal: clean the door, tape a hinge, squeegee from the middle out. See how to install decals on a truck door.

Alignment

Neither style forgives a crooked placement. With cut letters you align a baseline, the invisible line the lettering sits on. With a rectangle you align its edges to something on the door, such as the lower edge or a body line. Rectangles give you a visible edge to check against, which many people find easier, but a tilted rectangle shows just as clearly as tilted letters. Mark both doors from the same landmarks so they match.

How they look on different door colors

Cut letters look painted on, and the door itself is the background. On a door with strong contrast to the lettering that looks clean. On mid-tone, striped, faded or dirty paint, the contrast gets weaker.

A rectangular decal carries its own background, so the contrast is set by your color pairing, not by the paint. The trade-off is that the rectangle reads as a label. On a door that matches the sticker color, such as a white sticker on a white door, the edge can nearly disappear, though paint whites vary.

This matters for the federal marking rule, 49 CFR 390.21, which asks for letters that contrast sharply in color with the background they sit on, readable from 50 feet in daylight on both sides. With cut letters that background is your paint. With ours it is the sticker color. The customer is responsible for compliance, so confirm your requirements with FMCSA or your state. Our USDOT number display rules page has the summary, and truck lettering fonts and colors shows which pairings read clearly.

Repairs and changes

If one cut letter peels or gets damaged, a sign shop may be able to replace just that letter, though new vinyl can look different next to weathered vinyl. If your MC number changes, new digits have to be cut.

With a rectangular decal you replace the whole piece. Our 3-year guarantee covers a free replacement if a decal peels or comes off. It does not cover damage from misuse, abrasive cleaning, or removal and reapplication, and it does not cover a number that was typed wrong. Our refunds and returns page has the details.

Removal

Either style can leave ghosting, an outline where sun and weather reached the surrounding paint but not the paint under the vinyl. Cut letters can leave letter-shaped outlines, and a rectangle leaves a rectangular footprint. Both come off with the same careful method, covered in our guide on how to remove truck decals.

Price

Sign shops price cut lettering in their own ways, so ask for the total for both doors. Ours is built line by line, starting at $12.99 per decal, with a fixed amount for each extra line, width or lettering color. See truck lettering cost for worked examples. If you want a designed look, our 35 ready-made logo designs are $120 per door, with a proof sent before printing.

Which one to choose

Cut letters fit when:

• you want a painted-on look with no visible panel
• the door color already contrasts strongly with your lettering
• the lettering is large and runs across a big panel
• a sign shop will install it

A rectangular decal fits when:

• you want to install it yourself
• the door is a mid-tone, striped, dirty or mixed color
• you want the contrast fixed regardless of the paint
• you want two identical doors from a preview you have checked

For sizing either one, see our truck door decal size guide. To order a rectangular decal, start with the Custom USDOT Logo, the USDOT Decal Sticker or the Make-Your-Own 5-Line.
