What is the Wrap Readability Score?

The Wrap Readability Score is a 0 to 100 rating WrapMasters uses to evaluate how effectively a vehicle wrap communicates at traffic speed. It measures five factors, visual hierarchy, contrast, copy volume, font selection, and rear panel effectiveness, weighted by their relative impact on legibility. A score of 85 or above indicates a wrap that is performing well. Below 65, specific factors are limiting lead generation.

How is the Wrap Readability Score calculated?

The score is the sum of five weighted factor scores: visual hierarchy (30 points), contrast and legibility (25 points), copy volume (20 points), font selection (15 points), and rear panel effectiveness (10 points). Each factor is evaluated against specific, observable criteria, not subjective design preferences. The total maximum is 100.

What score does a vehicle wrap need to generate consistent leads?

In WrapMasters' evaluation framework, wraps scoring 85 or above consistently generate leads in proportion to their impression volume. Wraps in the 65 to 84 range generate leads but underperform relative to their daily impressions. Wraps below 65 generate significantly fewer leads than the impression count would predict. The gap between a 60-score and an 85-score wrap, in terms of actual call volume, is usually substantial.

Can I calculate my own Wrap Readability Score?

Yes. The scoring criteria for each factor are detailed on this page. Evaluate each factor from the same viewing conditions as a passing driver, 100 feet for hierarchy and font, 50 feet for contrast and rear panel, and total the scores. WrapMasters also offers a free wrap audit that includes the scored evaluation and specific recommendations for improving each factor.

What is the most common factor that lowers the Wrap Readability Score?

Copy volume and visual hierarchy are the two most commonly failing factors. Most underperforming wraps either have too much text competing for the viewer's attention, or the design leads with a logo or tagline rather than the company name and service category. Both issues are design decisions made before the wrap went to print and typically require a redesign rather than a spot correction.

Wrap Readability Score

A 0 to 100 rating that measures how effectively a vehicle wrap communicates at traffic speed.

"Does the wrap look good?" is not a useful question for evaluating whether a vehicle wrap is doing its job. Appearance is subjective. Lead generation is not.

The Wrap Readability Score is the evaluation framework WrapMasters uses to assess whether a vehicle wrap communicates effectively under the actual conditions it operates in: moving at 35 to 65 MPH, viewed from 50 to 150 feet, in two seconds or less.

The score is based on five factors, each weighted by its relative impact on legibility at speed. The total is a 0 to 100 number that predicts whether a wrap will generate leads in proportion to its daily impressions.

Score interpretation

85–100Strong

The wrap communicates effectively at traffic speed. All five factors are well-executed. Minor refinements may be possible but are not impacting performance.

65–84Functional

The wrap is legible under most conditions but has at least one factor that is reducing performance. Targeted corrections can move it into the strong range without a full redesign.

40–64Marginal

The wrap has significant legibility issues that are limiting lead generation. A partial redesign addressing the lowest-scoring factors is recommended.

0–39Failing

The wrap is not communicating effectively at traffic speed. A full redesign is required. Running this wrap as the company's primary street advertising is an opportunity cost that compounds daily.

The five scoring factors

Each factor is evaluated against observable, measurable criteria. Total weight: 100 points.

Visual hierarchy

30 points

Whether the most important information, company name and service category, dominates the layout. A wrap with strong hierarchy immediately communicates who the company is and what they do. A wrap with weak hierarchy asks the viewer to work to find that information.

25–30

Company name and service category are the two largest elements. Company name is at least 3x the size of supporting copy.

15–24

Company name dominates but service category is undersized or secondary to a tagline.

5–14

Logo or tagline leads the design. Company name and service category compete with other elements.

0–4

No clear hierarchy. No service category present.

Contrast and legibility

25 points

Whether the key text elements maintain sufficient contrast against the background across lighting conditions. Legibility collapses faster than most designers expect as distance and lighting vary.

21–25

Company name and phone number have high contrast against background in all lighting conditions. No decorative backgrounds behind key text.

13–20

Good contrast on most panels. One or two elements at the borderline in low light or at distance.

5–12

Contrast is insufficient on one or more key elements. Busy photographic backgrounds behind critical copy.

0–4

Key elements are not legible against background at traffic distance in variable lighting.

Copy volume

20 points

How many text elements compete for the viewer's attention. Every additional line of copy reduces the legibility of everything else. The best wraps carry five elements or fewer: name, category, phone, website, and one optional line.

17–20

Five or fewer text elements. No service lists, slogans, or secondary contact information.

10–16

Six to eight text elements. Some non-essential copy present but not severely cluttering.

4–9

Nine or more text elements. Service lists, multiple slogans, certifications, or social handles competing with key information.

0–3

Severely overcrowded. Key information is not identifiable without stopping.

Font selection

15 points

Whether the fonts used on key elements are legible at traffic speed. Script fonts, compressed fonts, and thin-weight fonts fail at distance before other font categories.

13–15

All key elements use clean, open-letterform fonts at sufficient weight. No script or highly decorative fonts on company name, category, or phone number.

8–12

Primary elements use legible fonts. Script or decorative fonts used for secondary elements only.

3–7

Script or compressed fonts on the company name, service category, or phone number.

0–2

Decorative fonts on all key elements. Not legible at 50 feet.

Rear panel effectiveness

10 points

Whether the rear panel, the highest-dwell-time surface on a service vehicle, includes the company name and phone number at readable scale.

9–10

Company name and phone number on rear panel at sufficient size for a trailing vehicle at 50 feet.

5–8

Company name present on rear panel. Phone number absent or undersized.

2–4

Logo only on rear panel. Company name and phone number absent.

0–1

Rear panel blank or decorative only.
