Every type of mobile camera have some variant, such as focal length and minimum focus distance. You need perpare a maximum size photo, say 5R or 4R, you want to scan. try to use your mobile camera take that photo, reserve some margin and measure the distance between camera and photo. The distance is the light box height.
The light box width and depth depends on the photo dimension and add few cm margin.
Here is my measure for iPhone 6s taking 4R photo:
height: 16 cm
width: 21 cm
depth: 16 cm
The light box has 4 side surround and a removable top side, the bottom are placing photo so no need to made a bottom.
At the top it has a hole at the center for placing mobile camera, I also make a plate with a big hole for fixing the mobile camera fit to the center hole.
P.S. Thanks to user cafemiguel point it out, the word "hold" in the picture should be "hole".
