A big question I get asked is what is the ideal art size above a king bed. The answer is often subjective, but the best starting point is to keep your finished piece (the edges of the canvas or frame) between 60-80% the width of the furniture it’s hanging over, and I tend to like it closer to the 80% mark.
Ideal Frame Size Above King Bed
For the standard 76 inch wide king bed you should consider art that is between 45 and 60 inches wide. So if you’d like to hang a framed piece take a look at #3 (32×40 print in a 40×48 inch frame) and #4 above (40×50 print in a 50×60 inch frame).
Ideal Canvas Size Above King Bed
If you’re looking to hang a canvas then consider #3 (40×50) or #4 (48×60) above.
Or if you want to hang a pair of images or a gallery wall, treat the whole thing as one piece that’s between 45 and 60 inches wide.
Ultimately it’s your own personal preference, so use these examples as a starting point, and if you’re still not sure you can even experiment by taping paper to your wall to see what works best in your room.
