European Hinge Drilling Pattern For Cabinet Doors
This is the common drilling pattern for most european cabinet door hinges on the market today.
If you are looking for a replacement hinge this will be seen on the back of your cabinet door when your old hinge is removed.
The large hole is 35mm.
The smaller holes may be just screw holes in the wood or they can have plastic dowels in them. The center to center of these holes will be 45 mm apart.
If you draw a line between the centers of the 2 screw holes and another line parallel to it going through the center of the 35 mm hole, the lines will be 9.5 mm apart.
