Sizing 3-ring Binders is easy if you have a little information.

Naked Binder offers four different ring sizes

1" D-ring holds up to 220 sheets of paper, 25 to a case

1.5" D-ring holds up to 350 sheets of paper, 18 to a case

2" D-ring holds up to 450 sheets of paper, 15 to a case

2.5" D-ring holds up to 550 sheets of paper, 12 to a case

How do you measure a ring size?

The flat side of a D-ring is part you measure when figuring out ring size.  If you are currently using a round ring, you measure the diameter from top to bottom.

How many sheets it holds is only one way to measure your binder. Sometimes it is nice to know the actual dimensions.

Naked Binders are configured to hold 8.5" x 11" paper (US standard paper).
