The hinge is 35mm (~1-3/8" +rch) it is usually setback from the edge of the
stile by 1/8" and you would want at least that much solid wood for the other
side so..... 1-5/8" min width would be my guess based on 40 face-frame
cabinet doors I just helped hang.
It Depends On Which Hinge, there are many Hinge Configurations,
If you have to0 they have one that takes a 26MM bore that is for real small
If you any exact sizes I can Scan the specs and e-mail them to you.
