How do you measure binder ring size? Finding the size of a 3-ring binder - Naked Binder

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).
