These frames only look like they’re hanging.  They’re actually all supported on screws so they always stay straight and are easily accessible to swap out pictures.  These measurements will work for a space that is at least 93″ wide. A NOTE ABOUT PICTURE SIZE: I use ShutterFly to print out all my photos. For the smaller frames I used 8×10 photos that fit w/in the mats included with the frames. For the larger frames I used 16×20 photos with a lot of background that wouldn’t crop out the subject when the mat was added. Alternately, Shutterfly has the option to add a white border to your photo before you print it which would help avoid the cropping issue.
