Closed folder sizes

A closed folder wraps a stack of pages like a flat box and locks shut with a tongue. It is made in the same sizes as a presentation folder, one for each paper size. Here they are, so you can start from the one that fits your pages.

Common printers' sizes, not a standard: A4 folders run from about 215 × 305 to 225 × 315 mm. Check with your printer before you order.

How to measure

  • Width and height: the folder closed, a little bigger than your pages: a 216 × 279 mm letter page goes in a 229 × 305 mm folder.
  • Stack thickness: how thick your stack is. 1 mm holds about 10 sheets of office paper, so 10 mm holds about 100. The spines and the walls are made that deep.
