Self-locking folder sizes
A self-locking folder holds papers in a pocket that locks with a tongue in a slot, so it needs no glue. It is made in the same sizes as other card folders, each for a paper size. Here they are, so you can start from the one that fits your pages.

How to measure
- Width and height: one cover, closed, a little bigger than your pages: a 216 × 279 mm letter page goes in a 229 × 305 mm folder.
- Stack thickness: how thick a stack the pocket holds. 1 mm is about 10 sheets of office paper, so 4 mm holds about 40. Between 3 and 9 mm.
How it locks
The pocket is two flaps on the back cover, one from the side and one from the bottom. Fold the side flap in, then the bottom flap up over it, and push the tongue on the bottom flap through the slot in the side flap. The pocket's size follows the cover: the side flap is a third of its width, the bottom flap a fifth of its height.
