HOW TO MEASURE RADIUS CORNERS

To determine if you have 1/4" or 5/8" radius corner hinges, measure from the beginning of the curve to where the corner of the hinge would be if it was square.

HOW TO SELECT THE PROPER HINGE SIZE

To consider the proper hinge size consider the following:
  • Door Height:
  • Door Weight:
  • Door Width:
  • Door Thickness:
  • Trim Dimension Required
Thickness of Door Width of Door Height of Hinge
1-3/8" Door to 32" 3-1/2"
1-3/8" Door 32" to 36" 4"
1-3/4" Door to 36" 4-1/2"
1-3/4" Door 36" to 48" 5"
1-3/4" Door over 48" 6"
2", 2-1/4", 2-1/2" Door to 42" 5" Heavy Weight
2", 2-1/4", 2-1/2" Door over 42" 6" Heavy Weight

NUMBER OF HINGES PER DOOR

As a general rule you will want to use 1 hinge per every 30" of door or fraction thereof.

Referring to door height:

  • Doors up to 60" - 2 hinges
  • Doors over 60" but not over 90" - 3 hinges
  • Doors over 90" but not over 120" - 4 hinges.
