Here are some of the framing costs that I have calculated so far.
16×20 frame for 11×14 prints:
Aluminum w/glass and mat = $16.00
Aluminum w/plexi and mat = $20.00
Wood w/glass and mat = $31.00
Wood w/plexi and mat = $35.00
20×24 frame for 16×20 prints
Aluminum w/glass and mat = $24.00
Aluminum w/plexi and mat = $32.00
Wood w/glass and mat = $41.00
Wood w/plexi and mat = $49.00
Mount and Laminate at ARC with frame (using your own) = $45.00
All of these prices are approximations and assume that you will buy materials in larger sizes, cut down, and cut window mats.
It may be possible to lower costs if you buy materials together as a group.
All prices were determined by using the websites framingsupplies.com and lightimpressionsdirect.com
