You’ve seen them. The banners that look great from three feet away but turn into a blurry, illegible mess the second you step back. It’s frustrating. You spend three hours cutting out felt or painting cardstock only to realize your "Happy Birthday" looks like a ransom note written in a blizzard.
Making letters on banners is actually a game of math and physics disguised as a craft project. If you don't get the kerning—that's the space between letters—right, your message dies. People think it's about being artistic. Honestly? It’s more about being a bit of a stickler for measurement. Whether you're using a Cricut, a stencil, or just a steady hand and some acrylics, there are rules to this. Real ones.
The Distance Rule for Banner Legibility
Most people fail because they don't account for the "Reading Distance." If your banner is hanging across a gymnasium, a two-inch letter is basically invisible. According to the Pennsylvania Department of Transportation (PennDOT) signage standards—which, weirdly enough, is the best place to look for readability data—every inch of letter height gives you about 10 feet of readable distance.
Need people to read it from 100 feet away? Your letters better be at least 10 inches tall.
Don't just guess. Measure the space where the banner will hang before you even touch a pair of scissors. If you're at a protest or a stadium, you're competing with visual noise. Big, bold, and blocky wins every single time. Script fonts? Forget it. They look elegant on a wedding invitation, but on a 10-foot vinyl strip, the loops and swashes bleed into each other. You want a sans-serif look. Think Helvetica or Impact.
Why Hand-Cutting Letters is a Dying (But Better) Art
We live in the era of the digital plotter. Machines like the Cricut Venture or the Silhouette Cameo 4 have made how to make letters on banners a push-button task for many. But machines have limits. They usually cap out at 12 or 24 inches in width. If you’re making a massive "Welcome Home" banner that spans a garage door, you’re going back to basics.
Old-school sign painters use a "pounce pattern." You draw your letters on thin paper, prick holes along the outlines, and then "pounce" a charcoal bag over it to transfer the ghost of the letter onto your fabric. It’s messy. It’s tactile. It’s also the only way to get a 3-foot-tall letter looking perfect without a $5,000 industrial printer.
If you’re hand-cutting, use a template. Do not "freehand" it unless you are a professional calligrapher. Even then, don't. Draw one "O" and use it for every "O" in the word. Consistency is what makes a banner look professional instead of like a last-minute school project.

Material Matters: Why Paper Usually Fails
If this banner is going outside, paper is your enemy. Humidity makes it curl. Wind rips it. If you're serious about your signage, you’re looking at 13oz vinyl or 420D nylon.
For DIYers, felt is the secret weapon. It doesn’t fray when you cut it. You can glue it with Eileen’s Tacky Glue or a hot glue gun, and it has a matte finish that doesn't reflect sunlight. Reflective glare is a silent killer of banner readability. If you use glossy plastic letters, the sun hits them at 2:00 PM and suddenly nobody can read your "Grand Opening" sign because it's just a white flash of light.
The Secret of Negative Space
The biggest mistake? Crowding.
You need "white space." Or "negative space." Whatever you want to call it, it's the empty area around your letters. A good rule of thumb is the 70/30 rule. Your letters should take up no more than 70% of the vertical height of the banner. If you have a 24-inch tall banner, your letters shouldn't be taller than about 17 inches. You need that "margin" at the top and bottom so the eye can track the words easily.
And kerning! Oh man, kerning is everything. The letters "A" and "V" should be closer together than "M" and "N." Why? Because the diagonal shapes create natural gaps. If you space every letter exactly two inches apart, the word "AVALANCHE" will look like it has giant holes in it. You have to "eye" it. Stand back. Squint. If it looks like a tooth is missing, move the letters closer.
Pro-Level Execution: The "Blue Tape" Hack
Here is a specific trick used by retail window dressers. When you’re ready to place your letters, don’t glue them yet. Use low-tack blue painter's tape. Tape the letters onto your banner material. Then, hang the banner up.
Walk 50 feet away.
Is the "S" sagging? Does the "W" look like an "M"? Correct it now while it’s just tape. Once you apply the permanent adhesive—whether it’s spray mount, fabric glue, or heat-transfer vinyl (HTV)—there is no going back. Especially with HTV; once that glue melts into the fibers, that’s the banner's permanent identity.
Tools You Actually Need
- A T-Square: Essential for keeping letters on a straight line. Banners that tilt "downhill" look amateur.
- X-Acto No. 11 Blades: Buy a bulk pack. A dull blade drags and tears the material. You’ll go through three blades for a 10-foot banner.
- Self-Healing Cutting Mat: Don't ruin your dining table.
- Chalk Pencil: For marking guides on dark fabric that wipe away later.
Specific Techniques for Different Mediums
If you're working with paint, the "dry brush" technique is your friend. If your brush is too wet, the paint will bleed under your stencil or follow the weave of the fabric (this is called "wicking"). Use a stiff-bristled stencil brush and dab vertically. It takes longer. It’s tedious. But the crisp lines are worth the effort.
For those using a projector—a common "cheat" for big banners—make sure the projector is perfectly level. If the projector is angled up or down, you’ll get "keystoning," where the letters at the top are wider than the letters at the bottom. It's a subtle distortion that makes people feel slightly dizzy when they look at it.
The Contrast Factor
Black on yellow.
That is the highest-contrast color combination known to man. It’s why caution tape and bumblebees use it. If you want maximum visibility for your letters, use black text on a yellow background or white text on a dark blue/black background. Avoid red on green (it vibrates and is hard for colorblind individuals to read) or light blue on white (it just disappears).
Think about the environment. If your banner is hanging against a brick wall, a red banner will blend in. You want a color that "pops" against the background of the building or the sky.
Actionable Steps for Your Next Project
- Calculate your height: Determine the furthest distance your audience will be. Divide that footage by 10 to get your minimum letter height in inches.
- Choose your font wisely: Stick to heavy, sans-serif fonts for anything meant to be read from more than 20 feet away.
- Draft with tape first: Position your letters with painter's tape and view from a distance before final application.
- Mind the margins: Leave at least 15% of the total height as "breathing room" at both the top and bottom edges.
- Check your contrast: Use a high-contrast color scheme like black on yellow or white on navy to ensure the message cuts through visual clutter.
Stop worrying about making it "pretty" and start focusing on making it readable. A banner is a tool for communication. If the letters aren't legible, the tool is broken. Stick to the math, watch your spacing, and use the right materials for the environment. You'll end up with a banner that actually does its job.
Next Steps
- Identify the primary viewing distance for your event to set your letter scale.
- Select a high-contrast material pairing, such as white felt on a navy blue canvas.
- Create a single letter template to ensure consistency across the entire message.
