Paper Sizes Chart (Inches and Millimeters)
Exact dimensions of US and international paper sizes, photo prints, index cards, envelopes and business cards, in inches and millimeters.

Printing on the right paper
When you print something that must be an exact size, such as our printable ruler, choose the PDF made for your paper and print at 100% / Actual size. Printing an A4 file on Letter paper, or the other way round, makes printers scale the page and changes the size.
