Sizing Large-Format Prints for Viewing Distance
How far away your audience will be should decide your print size, text size and image resolution for banners, posters and signage.
Think about the viewer first
Large-format prints are seen from a distance, and that distance should drive every design decision. A pull-up banner in a foyer is read from a few steps away. A fence banner at a sports field may be read from across the field. A directional sign needs to be read by someone walking or driving past.
Choosing the overall size
Measure the space where the print will go, and stand where your audience will stand. Use masking tape or a sheet of paper on the wall to get a feel for the size. A print that seems huge on screen can look small on a large wall, and a print that is too big for its space can look cluttered.
Text size and hierarchy
The further away the viewer, the larger and simpler the text needs to be. Limit the number of words, use a clear, bold typeface, and make the most important message the biggest element. Contact details and fine print should still be large enough to read from where people will actually stand.
- One main message per banner works best
- High contrast between text and background improves readability
- Avoid thin, decorative fonts for anything that must be read at a distance
- Test by viewing your design on screen at a small size, which mimics viewing from far away
Image resolution and distance
Because large prints are viewed from further away, they do not need the same image resolution per inch as a business card held in the hand. However, images still need enough detail for the final size, especially for prints viewed up close, such as exhibition graphics or pull-up banners at a stand. Supply the largest, original image files you have, and use vector logos.
Standard sizes and proportions
Posters are often printed in A-sizes such as A3, A2, A1 and A0, which all share the same proportions, so a design can scale between them. Banners are usually specified in millimetres or metres. Design at the correct proportions from the start, because stretching a design to fit a different shape distorts it.
Before you order
Confirm the final size, mounting method and viewing distance, then check the product options for finishing. Very large prints and specialist finishes may need longer than same-day, so plan ahead where you can.
