Banner sizes: the common dimensions and how to pick yours

Banner printers will make almost any size, but most orders cluster around a handful of standard dimensions. Those sizes are popular for practical reasons: they fit common walls, fence panels and booth spaces, they use printer roll widths efficiently, and they are big enough to carry a short message at a readable size.

This guide lists those standard sizes, what each one does well, and a simple method for choosing between them. If you are not sure what material to order, start with the vinyl banner buying guide; this page is about dimensions.

The common sizes at a glance

The letter heights above are what fit comfortably with margins and a second line of smaller text. They are not the minimum readable size, which depends on distance; see below.

Step 1: measure the space, not your wish

Measure the actual wall section, fence panel, railing or booth wall. Then take off a margin for fixings: on a fence you need a few inches each side so the ties can pull the banner tight; on a wall you need room for hooks or anchors; on a porch railing you need clearance from posts. A 6-foot fence panel between posts usually suits a 5 or 5.5-foot banner better than a 6-foot one.

Also check for obstacles you will not notice until hanging day: downspouts, light fixtures, windows, a tree branch in front of the best spot, cars parked along the curb at the height of the bottom edge.

Step 2: work out the reading distance

Size follows from how far away people will be. A common rule in the sign trade is about 1 inch of capital-letter height for every 25 feet of viewing distance for comfortable reading, and closer to 1 inch per 10 feet if you need people to take it in at a glance, as drivers do. Our letter height calculator does this for you.

Work through an example. A store banner must be read from across a four-lane road, about 100 feet. At 1 inch per 25 feet, the main line needs 4-inch capitals; for drivers, 8 to 10 inches is better. The words "GRAND OPENING" are 12 characters plus a space. At 9-inch capitals in a bold font, each character takes roughly 6 to 7 inches of width, so the line needs about 7 feet, plus margins. That points to a 3 x 8 or 3 x 10 ft banner, not the 3 x 6 ft size most people order by default.

Step 3: count your lines

Every line you add either shrinks the text or needs more banner. A strong banner usually has:

1. One main line (the event, offer or name).
2. One supporting line (the date, a phone number or website).
3. Optionally a logo or one photo.

If the copy needs more than that, the job is probably a poster, a flyer or a sign people stand in front of, not a banner seen from a distance. Our banner design guide covers layout in detail.

Step 4: decide on orientation

Most banners are landscape because they hang on fences, walls and railings that are wider than they are tall. Portrait banners make sense on narrow pillars, light poles, either side of a doorway and on banner stands. Pole banners for streets are commonly made around 18 x 36 in, 24 x 36 in, 30 x 60 in or 30 x 72 in, and the bracket kit dictates the exact size, so buy the hardware first.

Sizes for specific jobs

Party and celebration banners

For indoor parties, a 2 x 4 or 2 x 6 ft banner above the cake table is usually enough. Outdoors on a garage door, a fence or a porch, 3 x 5 or 3 x 6 ft reads well from the street and photographs better. See our graduation banner guide and birthday banner guide.

Business and storefront banners

Storefront banners are read by passing drivers, so they need to be larger than you think: 3 x 8, 3 x 10 or 4 x 10 ft are common. Check sign rules first; many cities limit the size and duration of temporary banners. Our grand opening banner guide has a checklist.

Trade shows and events

Booth backwalls are usually 8 feet tall and either 10 or 20 feet wide, and retractable banner stands come in standard sizes, commonly around 33 x 80 in. Measure the booth package before ordering. See trade-show booth graphics.

Fences and construction sites

Fence banners usually match panel sizes. Chain-link panels are often 6 feet tall, so 4 x 8 ft or 5 x 10 ft mesh banners are common. Use mesh on open fences; see mesh vs vinyl.

Does size change the price much?

Banner prices scale roughly with area, so a 4 x 8 ft banner (32 square feet) costs noticeably more than a 3 x 6 ft (18 square feet), though not always proportionally, because finishing, setup and shipping are partly fixed costs. Very large banners may need to be joined from two widths of material, which adds a seam; ask the printer where it will fall so it doesn't cut through a face or a line of text. Shipping is often the surprise: a banner that must ship rolled in a long tube costs more than one that can be folded.

A note on resolution for big banners

Bigger is not automatically blurrier. A banner seen from 30 feet doesn't need the pixel density of a framed photo. Around 100 to 150 pixels per inch at full size is plenty for most banners, and photos can drop lower for very large prints viewed from far away. Logos and text should always be vector. See the print resolution guide.

Checklist before you order a size

• Space measured, with margins for fixings subtracted.
• Viewing distance estimated and main-line letter height checked.
• Copy cut to one main line and one supporting line.
• Orientation fits the location (and hardware, for poles and stands).
• Local sign rules checked for outdoor business banners.
• Paper mock-up hung and viewed from the audience's spot.

Questions people ask

What is the most popular banner size?

3 x 6 ft is the most common general-purpose banner size. It fits most fences and walls, carries a short message at a readable size from the street, and is easy to hang and store.

What size banner do I need for a storefront?

Usually 3 x 8 ft or larger, because drivers see storefront banners from 50 to 150 feet away. Measure the fascia or window area first and check your city's temporary sign rules.

How big should the letters be on a banner?

A practical rule is at least 1 inch of capital-letter height for every 25 feet of viewing distance, and about double that for drivers who only glance. So 4 inches minimum at 100 feet.

Are banner sizes height by width or width by height?

Printers vary, so always check. Many list width first (6 x 3 ft), others list height first (3 x 6 ft). Include orientation (landscape or portrait) in your order notes to avoid confusion.

Can a banner be any size?

Most printers will make custom sizes. Very wide banners may be joined from two roll widths, which adds a seam, so ask where the seam will fall.
