Location of Hinges on Doors
How to determine the number of hinges per door
| 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
NOTE: The following chart is only an example. Job situations will vary
| 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 |
| LOCATION OF HINGES ON DOOR |
Top hinge 5" from jamb rabbet to top edge of barrel.
Bottom hinge 10" from bottom edge of barrel to finished floor
Third hinge centered between top and bottom hinges
The above is U.S. Standards procedure
| 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.
