Measure the opening
Use the usable frame opening, not the outside edge or the visible mat window.
All features
Frame matching
Great frame. Will it fit?
Compare full paper size with a frame’s usable opening. Both pieces can be things you’re considering.

Will this print fit this frame?
Compare pieces you own or are considering. Start with these example sizes, then enter your own.
Room for a mat
Frames hang either way, so both orientations are checked.
HOW IT WORKS
Three simple steps.
Compare with your artwork
Check the full artwork size in both orientations. Keep missing measurements visible.
Choose the next step
Review a close fit, plan a mat for extra space, or keep looking. Confirm a pair when you’re happy.
GOOD TO KNOW
What to know.
Does a photo tell you the size?
No. Fit comes from measurements you provide. A photo alone cannot establish size or clearance.
Does a size match guarantee a fit?
No. Check depth, backing, condition and any size tolerances in person. The sample below compares width and height only.
