How to Measure Cabinet Handles Correctly
Before choosing new cabinet handles, it helps to know exactly which measurements to compare. A handle’s full length tells you how it will look on the cabinet, but the distance between its mounting holes determines whether it will fit existing holes.
This guide explains how to measure for replacement handles, plan for new cabinetry, and check the details that affect installation. We have included millimeters and approximate inch equivalents for easy reference.
Start with the mounting hole spacing
The most important measurement when replacing a cabinet handle is center to center, sometimes abbreviated as CTC. This is the distance from the center of one mounting hole to the center of the other.
It is not the distance between the ends of the handle or the edges of its mounting bases.
If you want to reuse your existing cabinet holes, the replacement handle must have matching center-to-center spacing.
How to measure an existing handle
You will need a screwdriver, a ruler or tape measure with clear markings, and somewhere to record your measurements. A metric ruler is especially useful for hardware listed in millimeters.
1. Remove one handle
Open the door or drawer and locate the mounting screws on the inside. Support the handle while loosening the screws with a manual screwdriver.
Removing it allows you to see the cabinet holes and the threaded mounting holes on the back of the handle.
2. Measure between the hole centers
Place the ruler across the two cabinet holes and measure from the center of one opening to the center of the other.
You can also measure between the centers of the threaded holes on the back of the removed handle. Keep the ruler straight and check the reading twice.
Record the measurement in millimeters whenever possible. If the holes are worn, oversized, or difficult to read, compare the cabinet measurement with the mounting points on the handle.
3. Measure the full handle length
Measure the handle from its outermost point at one end to its outermost point at the other.
This is its overall length. Keep it as a reference when comparing replacement designs. A new handle can fit the same holes while extending farther across the cabinet front—or covering less of it.
4. Check the base and cabinet surface
Look at the area beneath each mounting base. Existing hardware may leave an indentation, a finish difference, or a visible outline.
Compare the replacement’s base dimensions with these marks. Matching the mounting holes does not guarantee that a smaller base will cover the area left by the old handle.
5. Repeat for other cabinet sizes
Do not assume every handle in the room has the same spacing. Wide drawers, narrow cabinets, and pantry doors may use different sizes.
Measure one example of each size and record how many replacements you need.
Check projection and finger clearance
Two handles with similar lengths can feel quite different in use.
Projection is the distance from the cabinet face to the outermost part of the installed handle.
Finger clearance is the usable space between the cabinet surface and the underside of the grip. Projection and finger clearance are related, but they are not the same measurement: a thick handle can project farther while leaving less room underneath.
Check that the new handle will be comfortable to grasp. Also consider nearby walls, adjoining doors, and other handles that could come into contact when the cabinetry opens.
When available, use the product’s dimension drawing to compare these details.
Common center-to-center sizes
The table below shows frequently used metric hole spacings and their approximate fractional inch equivalents. These are mounting measurements, not overall handle lengths.
| Center to center in millimeters | Approximate center to center in inches |
|---|---|
| 96 mm | 3¾ inches |
| 128 mm | 5 inches |
| 160 mm | 6⁵⁄₁₆ inches |
| 192 mm | 7⁹⁄₁₆ inches |
| 224 mm | 8¹³⁄₁₆ inches |
| 254 mm | 10 inches |
| 320 mm | 12³⁄₅ inches |
The inch values are approximate display sizes, rounded for reference. Always use the exact measurement specified for the hardware when checking fit or marking new holes.
Some handles use true inch spacing, such as 3 inches or 5 inches. Measure your existing hardware rather than assuming it matches the nearest metric option.
Measuring for new cabinets
When your cabinet fronts have not been drilled, you have more flexibility. Start by measuring each door and drawer front, then compare the hardware’s overall dimensions against it.
Record the cabinet dimensions
Note the width and height of each front. On Shaker or other framed cabinetry, measure the usable flat area of the frame as well. The handle’s mounting bases should sit fully on a suitable flat surface, clear of beveled edges or molding.
Compare overall lengths
For drawers, a handle with an overall length around one third of the drawer width can be a useful starting comparison. Try shorter and longer options before deciding.
This is a visual guideline, not a required ratio. It should not be applied automatically to cabinet door height. On doors, consider the frame width, comfortable reach, and the appearance of the handle in its intended position.
Make a full-size template
Cut a paper outline to the handle’s overall length and width. Position it on the cabinet using tape appropriate for the finish.
Look at it from across the room and from your normal standing position. An outline helps you judge scale; holding an actual handle in place helps you check grip, projection, and clearance.
Once the placement is approved, use the actual handle and its specified center-to-center measurement to locate the mounting holes.
Measure cabinet thickness for the screws
The door or drawer-front thickness affects the screw length needed for installation.
Measure the material the screw must pass through. On some drawers, this includes both the decorative drawer front and the drawer box behind it.
The screw must have the correct thread and engage securely without bottoming out before the handle sits against the cabinet. A screw that is too long can leave the handle loose even when it feels fully tightened. Do not try to correct this by tightening harder.
Check the hardware’s installation requirements before selecting replacement screws.
What if the hole spacing is different?
A handle with different mounting spacing will generally require new holes. Before making changes, consider how the old holes and any marks beneath the previous hardware will be concealed.
Depending on the cabinet finish and the replacement design, options may include:
- Choosing another handle with matching hole spacing.
- Having the old holes professionally filled and the surface refinished.
- Using a suitable backplate that fully covers the old holes and accommodates the new mounting positions.
Check the actual backplate dimensions and fixing arrangement before ordering. A backplate does not automatically make every handle compatible with every existing hole pattern.
Avoid forcing screws into mismatched holes or angling them to make a handle fit.
A quick check before ordering
Confirm these details for each handle size:
- Center-to-center spacing: Does it match the existing holes?
- Overall length: Does it suit the cabinet front?
- Mounting base dimensions: Will the bases sit flat and cover any existing marks?
- Projection and finger clearance: Is there comfortable room to grip and open the cabinetry?
- Cabinet thickness and screws: Are the thread and screw length suitable?
- Quantity: Have you counted each size separately?
Keep these measurements together when comparing products. It makes it much easier to distinguish a handle that looks similar from one that will fit correctly.
Install carefully
Check the hardware against the cabinet before drilling, and confirm each hole position using the actual piece or an appropriate installation jig.
Tighten all cabinet handles and knobs by hand using a manual screwdriver. Avoid power drills and impact drivers, and tighten only until secure. Overtightening can damage the hardware, threads, or cabinet surface.
If a handle does not sit properly, stop and check the alignment and screw length rather than applying more force.
