Too many words, weak contrast, wrong spot: sign mistakes that cost you customers

Most sign mistakes are about reading, not building

The most common business sign mistakes are too many words, colors without enough contrast, letters too small for the distance people read them from, logos reproduced from low-resolution files, and placement where trees, awnings or neighboring signs hide the message. Close behind are signs that ignore the landlord's criteria, the city's rules or accessibility requirements, and signs that drift away from the brand with old logos and outdated phone numbers. Every one of them is cheaper to fix on a proof than on a wall.

We design, produce and install signs at our FASTSIGNS center near Fair Park, and a good part of our design work is talking customers out of these mistakes before production. Here is each one, what it costs you, and the fix, in roughly the order we run into them on real projects.

Writing a paragraph where a headline belongs

The urge to list every service on the sign is strong, especially for a new business. But people read a building sign from a moving car or across a parking lot, and they take in a few words at most. Every extra line makes the important words smaller and harder to find. The building sign needs the name and, if the name does not say it, what you do. Everything else belongs on the website, the window, the door or the brochure.

The same discipline applies to taglines and slogans. A clever line that needs a second read is a line nobody driving past will finish. If a tagline is part of the brand, give it a smaller, separate place, such as the window or the monument panel, so it never competes with the name for space on the main sign.

The City of Dallas cares about this too, in its own way. Its summary of sign rules for business zoning districts notes that window lettering taller than four inches counts toward the word limit for a facade. A crowded window is not only hard to read; it can run into the rules.

• Building sign: name and, if needed, what you do
• Window and door: hours, phone, website and a short list of services
• Inside: menus, price lists, promotions and details

Colors that look fine on screen and vanish outside

Contrast is what makes a sign readable, and it is about lightness, not just color. Red on black, navy on dark green, or yellow on white can look striking on a monitor and turn into a blur at 100 feet in bright sun. A quick test is to convert the design to grayscale: if the letters and the background turn into similar grays, the sign will be hard to read.

Brand colors still matter, and we can match them precisely using the Pantone system or a printed test swatch. The answer is usually to keep the brand color and adjust what sits next to it: a white outline, a darker background panel, or reversing the colors so the light one carries the letters.

Letters sized for the office, not the road

A design approved on a laptop screen at arm's length gives no sense of how it reads from the street. Before you approve a size, stand where your customers will be when they need to see the sign: the far side of the parking lot, the turn lane, the sidewalk across the street. Ask how far that is and design for that distance, not for the view from the front door.

Thin, decorative and script typefaces lose legibility fastest with distance, and long words set in all capitals are harder to read at a glance than mixed case. If the logo uses a delicate script, consider pairing it with a bolder secondary line for the words that must be read. For a large exterior sign, a full-size paper mockup taped to the wall for an afternoon answers the size question better than any discussion. Spacing matters as much as size: letters crowded together blur into one shape at a distance, while a little extra space between letters and lines keeps each word distinct. Leave clear margin around the edges of a panel as well, so the words do not seem to run off it.

A blurry logo stretched to ten feet

Signs are cut and printed from vector artwork, which scales to any size without losing sharpness. The FASTSIGNS custom signs FAQ asks for logos as vector files, preferably .eps, with .ai or PDF also accepted, and says raster images need at least 100 to 150 dpi at full production size, depending on viewing distance. A logo saved from a website is usually a small raster image that turns soft and jagged at sign size.

If the original vector file is lost, the logo has to be redrawn before production. That takes time and, if done carelessly, subtly changes the mark. Find the file now, while there is no deadline; it is usually with whoever designed the logo, or in an old email from them. Once you have it, keep it somewhere the whole team can reach, along with the exact brand colors, so every future sign, shirt and truck starts from the same source instead of a screenshot.

A good sign in a spot nobody sees

Walk and drive every approach to your location before deciding where the sign goes. Young trees grow into sign bands. Awnings, columns and covered walkways block the view from the parking lot. A neighboring tenant's projecting sign can hide yours from one direction completely. A monument sign placed where cars are already past the driveway by the time they read it does not help anyone turn in. Think about the season too: a sign band that is clear in January can be behind leaves by June.

Windows have their own placement logic. In Dallas business zoning districts, the city's summary limits window signs to 15 percent of the window or glass door and places them in the bottom third of the window. That happens to be where pedestrians look anyway, so it is a constraint worth designing for from the start.

Forgetting the sign has a day shift and a night shift

Many signs are designed for one condition only. An unlit sign may disappear after dark in winter, when a retail store or restaurant still has hours to fill. A lit cabinet with a white background may glow so brightly at night that the letters wash out. And a sign designed only for its night glow may look dull and gray in daylight, when it is actually seen most.

Ask for renderings in both conditions, and look at them on a phone as well as a large screen. If the business has evening hours, lighting is worth considering, and the type of lighting changes the look completely. Our comparison of channel letters, cabinet signs and dimensional letters explains how each behaves day and night.

Running into rules you did not know about

Three sets of rules catch businesses off guard. The first is the landlord's sign criteria, which can dictate type, size, color and lighting; a sign ordered before reading them may have to be redesigned. The second is the city. The City of Dallas sign permit pre-screen checklist notes that the name on the certificate of occupancy must match the name on the sign before the permit pre-screen can be approved, which surprises businesses whose legal name differs from their brand.

The third is accessibility. The U.S. Access Board's guide to the ADA Standards explains that signs identifying permanent rooms and spaces, such as restrooms and room numbers, need raised characters and braille, mounted with the tactile characters between 48 and 60 inches above the floor, and placed on the latch side of single doors, with a non-glare finish and strong contrast. A beautiful restroom sign at the wrong height, or on the wrong side of the door, is a mistake that has to be redone.

Letting the signs drift away from the brand

Over a few years, businesses collect signs from different vendors at different times: a building sign with the old logo, window graphics in a slightly different red, a lobby sign in another typeface, vehicle graphics from a third shop. Each piece is fine; together they look like several companies. If your website, brochure and signs no longer match, this guide on fixing a brand that looks like three different companies explains the design side.

Outdated information is the other drift: a phone number that changed, hours that changed, a service you dropped. Walk the location once a year as a customer would and list every sign that is no longer true or no longer matches. If the main sign itself has aged, see whether to repair or replace a business sign.

How we catch these before production

Our design process is built to catch these mistakes on screen. We ask for your vector logo, your brand colors, photos of the site and the landlord criteria; we show the sign as a rendering on your own building; and we flag readability, contrast and placement issues before anything is produced. Our team also makes sure signage meets local codes and can obtain permits when a project needs them.

Quotes are free, and we are open Monday through Friday from 8:30 to 5:00. Bring the sign you are planning, or the one you already have and are not sure about, and we will tell you honestly what would make it work harder for your business in Dallas.
