Hi Anne,

The listed available
sizes that you see for our picture frames are the sizes of the opening in the
back of the frame for your picture to be inserted. For example, a 20x24 size
frame has a 20x24 inch opening.

Of course, the wood
of the frame extends beyond the opening of the frame. The wood frame bordering
the photo is about 3 inches wide on each side of the frame, so the exterior
dimensions of this frame in total would be about 26x30 inches.

For this frame in particular, you’ll see our larger sizes
include 16x20, 18x24, and 20x24 inches.
