Logo for truck lettering: legible at fifty feet, not on a screen
A van is a moving billboard with a bad viewing angle. The logo is seen for a few seconds, at 30–50 feet, often in rain and almost always at an angle. Detail that looks refined on a monitor is simply not part of the message.
Truck lettering is not a bigger version of a business card. Distance removes thin strokes, low contrast removes whole shapes, and motion means the eye gets one pass. The mark has to work as a silhouette before it works as a drawing.
The lettering shop will also tell you that the material changes the file: cut vinyl, printed wrap and reflective film each want something slightly different. The good news is that one disciplined version of the mark usually serves all three.
Distance sets the size
| Typical viewing distance | Cap height to aim for |
|---|---|
| 10 ft (shopfront, close approach) | 1–1.5 in |
| 30 ft (passing traffic) | 3 in |
| 50 ft (roadside van) | 5 in |
| 100 ft (highway signage) | 10 in |
The rule of thumb is about one inch of cap height per ten feet of comfortable reading distance. Readability at the limit is roughly half that, but a logo that is only readable when you already know what it says is not doing the job.
What survives a moving vehicle
- Silhouette. If the mark is a solid shape with a clear outline, it reads before the details do. If it is a collection of thin lines, it reads as a smudge.
- Contrast. Mid-tone brand colours on a mid-tone van disappear. Put the mark on a high-contrast panel, or change the panel colour rather than the mark.
- One idea. The phone number and the service list are separate decisions. A logo with three visual ideas competes with both.
- Counters. Small holes fill in from a distance. At 50 feet, a counter under 2 cm is not adding information.
- Fine type. A tagline set at 20 mm is unreadable at speed; either give it real size or drop it.
The material decides the file
- Cut vinyl wants closed paths and minimum strokes; each colour is a separate layer.
- A printed wrap wants a high-resolution vector or a large raster, with bleed and panel breaks planned by the installer.
- Reflective film reflects back, so a complex mark can glare into a flat shape at night. A one-colour silhouette tends to be the most legible version.
- A partial wrap has to leave the manufacturer's door seams and windows clear; the shop will lay that out, but the mark should be designed to survive a crop.
Worked example: a plumber's van
The brief
A plumber's mark is a wrench crossed with a pipe, inside a shield, with the name at 40 mm below it on the door. The van is white.
At 40 mm the name is readable from about 13 feet, which is useful when the van is parked and useless in traffic. The crossed tools are three overlapping mid-grey shapes on white: at 50 feet they become a dark diamond.
The lettering version promotes the name to 180 mm cap height, reduces the tools to a single solid silhouette, and puts the whole lockup on the largest flat panel of the van. The phone number gets its own line at 90 mm. The full crossed-tool mark stays on the business card and the invoice.
What our pack ships
The Production Pack includes the mark as a single-ink vector and a mono silhouette. That is the geometry a lettering shop converts into a cut path, a one-colour panel or a wrap without redrawing. It is not pre-flighted for a particular cutter or film; the shop sets the minimum stroke and bridges.
It does not lay out the vehicle. Panel breaks, door seams, window cut-outs and installation are the shop's job, and they are better at it than a file can be.
Questions
How big should a logo be on a van?
Aim for about one inch of cap height per ten feet of normal viewing distance. A van seen from 30–50 feet wants a name at 3–5 inches. The mark can be larger, but the name should not be smaller than that.
Do I need a special file for reflective vinyl?
The same artwork works, but reflective film exaggerates complex detail and can glare. A solid one-colour silhouette is usually the most legible version at night.
Why does my lettering shop want a one-colour version?
Because every colour is a separate cut layer. A one-colour version is cheaper to make, easier to apply, and reads better at distance. The full-colour mark still belongs on packaging and the website.
If the file is the problem, the pack is the fix.
The Production Pack is $149, one time: true vector masters, six lockups, a print PDF and EPS, one ink per file and unlimited parametric edits.
