I am using non mortise extruded brass hinges for inset kitchen cabinet doors (specifically these http://www.horton-brasses.com/NM-7.asp). Doors are hard maple with shaker panel.

How many hinges should I use on the 38.5" upper cabinet doors? I have two 12" doors and one 16.5" wide door.

I would prefer just two but am concerned that is not enough. Thanks
