How far is the back of the curtain (not the frame) from the wall after the frame curtain is installed on the wall?

This depends on the installation requirements of the frame curtain. Generally, in order to ensure the smoothness of the frame curtain after pasting, you should use 12 cm multilayer board on the base of the frame curtain, and paste gypsum board on it, so that your frame and reserved bolt hole are 2.2 cm higher than the outside. In short, the distance between the picture frame and the wall should be determined according to the basic treatment method of the picture frame. It may be that you just need to stick one layer on the multilayer board, and there is no need to stick gypsum board on the multilayer board. The distance between the frame and the wall is only1.2cm..
