How to use the numbers

Set up your document at the scaled size, including bleed, then place photos that reach the pixel size shown. A photo with fewer pixels will look soft when printed this large.

Large graphics are often built at 25 or 10 percent of full size so the files stay manageable. Resolution is always judged at the full printed size: a file built at 25 percent needs four times the resolution in the document, which the calculator shows as the document resolution.

Why 100 pixels per inch is often enough

Booth graphics are seen from a few feet away or more, so they do not need the resolution of a brochure. Many printers ask for something in the region of 100 to 150 pixels per inch at full size for photos. Logos and text should be vector, so they stay sharp at any size.
