Banner size calculator for readable signs

A practical starting point is roughly one inch of letter height for every ten feet of viewing distance, so a banner read from thirty feet needs at least three-inch-tall letters. The banner size calculator applies this formula automatically when you enter the intended viewing distance and banner dimensions, giving you a recommended minimum height before you order vinyl banners from Cheap RUSH Printing.

Wind slits reduce load on the banner material during outdoor use, which matters for any piece exposed to steady or gusting wind. The banner size calculator evaluates your banner dimensions and suggests whether to add them based on size and expected exposure. For large format vinyl banners ordered through Cheap RUSH Printing, confirm with the production team whether slits should be cut pre-delivery.

For vinyl banners viewed from ten feet or less, aim for 150 DPI at the finished print size. Banners viewed from further distances can drop to 100 DPI without visible quality loss. The banner size calculator recommends a DPI target based on your size and viewing distance inputs. After confirming the target, run your artwork through the DPI resolution checker before uploading.

Standard grommet spacing is every 24 inches along the banner perimeter, which works well for most commercial installations. Larger or heavier banners may benefit from tighter spacing at every 18 inches to reduce stress on each grommet. The banner size calculator flags these adjustments based on width and height. Confirm final placement with Cheap RUSH Printing when placing your vinyl banner order.
