What is the ideal height to hang a 35" x 35" canvas print, from floor?

Roll over the top to fit 1/4 -1/2 in steel rod thru or fancy shower hooks n then the rod. Then use sturdy hooks n Some chins or twine maybe.

I would think it would be as any other picture. Your eye level @ 1/3 from the top. I have a tapestry over my couch so its position is determined by the height of the couch, about 6 inches above the couch. A lot of variables to consider. Go with where it looks good to you.

I'd try to center it..

As an artist and having worked in a gallery in my younger days, its eye height but then rules are made to be broken, so do what suits you. Personally I never like it when they are hung too high.

If you are going to be looking at the print mostly from a standing/walking postion in the home, then hang where it is at your eye level. If you are going to be looking at it mostly from a sitting height, then hang a little lower than standing eye level.

One of the most common mistakes people make when hanging art in homes is that they hang it too high on the wall.
