Determine Hinge Width:

Thickness of Door Hinge Width Maximum Clearance Provided
1.375" (1 3/8") 3.5" (3 1/2") 1.250" (1 1/4")
1.375" (1 3/8”) 4" 1.750" (1 3/4")
1.750" (1 3/4") 4" 1"
1.750" (1 3/4") 4.5" (4 1/2") 1.500" (1 1/2")
1.750" (1 3/4") 5" 2"
1.750" (1 3/4") 6" 3"
2.000" (2") 4.5" (4 1/2") 1"
2.000" (2") 5" 1.500" (1 1/2")
2.000" (2") 6" 2.500" (2 1/2")
2.250" (2 1/4") 5" 1"
2.250" (2 1/4") 6" 2"

The following formula may be used to determine the MINIMUM hinge width necessary:

  Door Thickness
  - Backset
  x 2
  + Clearance Required
  + Inset (if any)

  = Hinge Width (if not a standard width, use the next larger standard width)

(NOTE: Standard 4.5” wide hinge installed on 1.750” doors will clear 1.5” trim.)

The hinge width of Half Mortise, Full Surface and Half Surface hinges is standard, depending on the hinge height. In these hinge types, the amount of clearance available is determined by the amount of offset, not by the hinge width.
