How to measure

Measure the largest item going inside — including any envelope, backing board or mount — then compare its width and height with the usable internal dimensions below.

Allow enough room for the item to slide in comfortably.

Important

The dimensions shown are the usable internal bag size. The self-seal flap is additional to those dimensions.
