Banner sizing & grommets, explained

Start with how far away people will read it

Letter height drives everything. A rough rule: about 1" of letter height per 10 feet of viewing distance to be readable, and closer to 1" per 4 feet to really grab attention from the road. Our letter height calculator turns a viewing distance into a recommended size, which then tells you how big the banner needs to be.

Pick the material for the environment

• Standard vinyl (13oz)

  The go-to for most indoor and short-to-medium outdoor use.

• Heavy vinyl (18oz)

  More durable for long-term outdoor signage.

• Mesh

  Wind passes through — best for large outdoor banners and fences in exposed spots.

Finishing: hems & grommets

Standard finishing is hems (folded, reinforced edges) plus grommets (metal rings) for hanging, typically every 2–3 feet around the edges. Big outdoor banners may need wind slits or pole pockets. Use our banner grommet calculator to estimate grommet count and spacing for your size.

Common sizes

2x4 ft and 3x6 ft are popular for events and storefronts; 4x8 ft and up for buildings and highways. Any custom size is fine. Tell us where it is going and we will recommend size, material, and finishing — see vinyl banners or browse wide format.

Set up banner artwork that prints clean

Banners are forgiving on resolution because nobody reads them from arm's length. Aim for 100 to 150 ppi at full print size - far less than the 300 ppi you would want on a brochure. If your file is built at half scale, double those numbers. Not sure whether your photo or logo will hold up? Run it through our free image resolution checker before you send anything.

Keep every word and logo at least 3 inches in from the edges. The hem and grommet finishing covered earlier on this page claims the outer band of material, so anything sitting near the edge risks getting folded under or punched through. Backgrounds and colors should run all the way out; your message should not.

Send logos as vector files (AI, EPS, or PDF) whenever you can, and pick thick, simple fonts. Thin scripts that look elegant on a screen disappear at 50 feet. High contrast wins: dark text on a light background or the reverse. If your colors are close in value, the whole banner reads as a blur from the road.

Common banner mistakes we see

Too much text is mistake number one. A banner works like a billboard, not a brochure - drivers get a few seconds, so lead with seven words or fewer, one phone number or web address, and nothing else. Every extra line steals size from the headline that actually needed to be big.

Approving the proof at arm's length is a sneakier one. Every line looks readable when the design fills your monitor. Print the layout on a letter-size sheet - for a 3x8 ft banner that is roughly one-tenth scale - and view it from a tenth of the real viewing distance. You will see immediately which lines survive and which disappear, while there is still time to fix them.

Hanging is where good banners go to die. Never hang a large banner by the corner grommets alone - spread the tension across every grommet along the edge, and use bungee cords or elastic ties so gusts stretch the mount instead of tearing the material. After a big storm, give the corners and edges a quick look; catching a small tear early is the difference between a repair and a reorder.

A worked example: sizing a storefront banner

Say you are opening a shop on a main road through town where traffic moves at about 30 mph. Most drivers will first see your banner from roughly 100 to 150 feet away. Using the letter-height rule, your headline needs letters around 10 to 15 inches tall to register in the time they have.

A 12-inch headline plus a smaller second line and breathing room above and below points to a banner about 3 feet tall. Fit a short headline like GRAND OPENING at that letter height and you land near 8 feet wide - a 3x8 ft banner, a common size that keeps material cost sensible.

For budget, a standard 13oz vinyl banner in that size range typically lands in the low few hundred dollars, though material, finishing, and quantity all move the number. Treat that as a ballpark, not a promise - request a free quote with your size and location and we will price it exactly.

Vinyl banner or retractable banner: which fits the job

Choose a vinyl banner when it will hang on something: a storefront, fence, railing, or gym wall. Grommets make it easy to zip-tie or bungee up, take down, and reuse across seasons of events. Vinyl is also the only practical choice outdoors and for oversized or fully custom dimensions.

Choose a retractable banner when it needs to stand on its own indoors - trade shows, lobbies, school events, open houses. The stand is built into the base, setup takes about ten seconds, and the standard roughly 33x80 inch face is sized for people walking past at close range. See our retractable banners for options.

Plenty of local businesses end up with both: a grommeted vinyl banner that lives on the building or fence line, and a retractable unit that travels to every expo and community event. If you are only buying one, match it to where it will spend most of its life.
