Measuring Guide
Tips for measuring common hardware so you find the right fit for your project the first time.
Door edge to center of the borehole
Face to face, measured across the edge
The distance between the screw holes
Measure Backset Length
Backset is the distance from the edge of the door to the center of the borehole, where the knob or lock is installed.
- Locate the borehole, the large hole drilled through the face of the door for the knob or lock.
- Measure from the edge of the door (where the latch is installed) to the center of that borehole.
The most common backset measurements.
TipIf the door already has a knob installed, measure from the edge of the door to the center of the knob or lock cylinder.
Measure Door Thickness
Door thickness is measured across the edge of the door, from one flat face to the other. An accurate measurement ensures your hardware fits securely and operates correctly.
Most standard interior doors are one of these two thicknesses.
TipMeasure in several spots (top, middle and bottom) to check for warping, especially on older doors.
Center to Center vs. Overall Length
Center to Center (C-C)
The distance between the centers of the two screw holes. This is the standard measurement used to make sure a pull fits the existing holes in your cabinet or drawer. Example: 3″ C-C means the holes are 3″ apart.
Overall Length
The total length of the pull from end to end, which may be longer than the C-C measurement depending on the design. A 3″ C-C pull might have an overall length of 3-1/2″, 4″ or more.
TipIf you're replacing existing hardware, measure the distance between the screw holes (center to center) to find the right fit.
