Because GoodHangups are meant for flat PAPER art we don’t specify the weight but focus on the maximum size of flat paper art you can hang.   For GoodHangups, the maximum size of flat paper art you can hang is 24” x 36”For GoodHangups for Kids Art,  the maximum size of flat paper art is 9” x 12” but can often be larger.
Note: We set the max size small as sometime kids art has things glued to it and we want to take that into consideration.The main reason we don’t set a maximum weight is that, for example, if you had a thick piece of foam that didn’t weight much, it wouldn’t work even if it was under our maximum weight as the distance between the MagnaStickers (wall stickers) and the Magnets would be too large.
