Cabinet hinge overlay is how far the cabinet door covers the cabinet opening or face frame when the door is closed. If the overlay is wrong, the replacement hinge may not line up, the door may hit the neighboring door, or the reveal around the cabinet may look uneven.
Quick answer: for a centered overlay door, subtract the cabinet opening width from the door width, then divide by two. For example, a 17-inch door over a 16-inch opening has a 1/2-inch overlay on each side.
Important: full overlay, half overlay and inset describe door position, but they do not replace actual measurement. Two hinges can both be called full overlay and still have different overlay dimensions, plates or cabinet requirements.
Cabinet Hinge Overlay Calculator
Use this calculator when the door is centered over the opening. If the door is part of a pair, or if it uses unusual reveals, confirm the result with the hinge manufacturer’s installation sheet.
Cabinet Hinge Overlay Chart
| Door position | Typical overlay idea | What it means | Main buying risk |
|---|---|---|---|
| Inset | 0 inch overlay | Door sits inside the cabinet opening | Needs inset hinge and precise reveal |
| Partial overlay | Commonly around 3/8, 1/2, 5/8 or 3/4 inch | Door covers part of the face frame or opening edge | Buying a hinge with the wrong overlay dimension |
| Half overlay | Used where two doors share a partition | Each door covers part of a shared center stile or panel | Confusing half overlay with 1/2 inch overlay |
| Full overlay | Door covers most of the cabinet edge or face frame | Creates a cleaner, less exposed frame look | Assuming all full overlay hinges fit the same cabinet |
How To Measure Overlay With Tape
- Close the cabinet door.
- Place painter’s tape on the cabinet frame next to the door edge.
- Mark the outside edge of the closed door on the tape.
- Open the door.
- Measure from the cabinet opening edge to the mark on the tape.
- That distance is the overlay for that side.
Half Overlay Is Not The Same As 1/2 Inch Overlay
This is one of the easiest hinge mistakes. Half overlay usually describes a door arrangement where two doors share the same partition or center stile. 1/2 inch overlay is a measurement. They are not automatically the same thing.
If a product listing says 1/2 inch overlay, it is talking about a measured overlay. If it says half overlay, check the diagram and application before buying.
Face-Frame Vs Frameless Cabinets
A face-frame cabinet has a frame around the front of the cabinet box. A frameless cabinet does not have that same front frame. Hinge selection changes because the hinge attaches and adjusts differently.
For replacement work, identify the cabinet type before shopping. A hinge that fits a face-frame cabinet may not fit a frameless cabinet, even if the overlay language sounds similar.
Other Hinge Measurements To Check
- Cup diameter: many concealed hinges use a 35mm cup, but you should measure the existing bore.
- Cup depth: a shallow door may not accept a deep cup.
- Screw-hole distance: replacement hinges may not reuse the same holes.
- Opening angle: common hinges include 105-degree and wider-angle versions.
- Soft-close: useful upgrade, but fit comes before features.
- Mounting plate: especially important for frameless and concealed hinge systems.
What To Buy After Measuring
After measuring overlay, search by cabinet type, overlay amount, hinge style and opening angle. Useful product categories include 1/2 inch overlay soft-close hinges, full overlay concealed hinges, inset hinges, face-frame cabinet hinges and hinge mounting plates.
Do not buy a hinge only because it says soft-close. A quiet hinge that does not match the overlay is still the wrong hinge.
Common Mistakes
- Buying by old hinge appearance: similar-looking concealed hinges can have different overlays and plates.
- Confusing half overlay with 1/2 inch overlay: one is a layout term, one is a measurement.
- Ignoring cabinet type: face-frame and frameless cabinets use different hinge setups.
- Skipping the cup measurement: the cup bore matters for concealed hinges.
- Assuming full overlay is universal: full overlay is not one fixed measurement across all systems.

FAQ
What does overlay mean on cabinet hinges?
Overlay is how much the door covers the cabinet opening or face frame when closed. It helps determine which hinge will place the door correctly.
How do I calculate cabinet door overlay?
For a centered overlay door, subtract the cabinet opening width from the door width, then divide by two. That gives the overlay per side.
Is half overlay the same as 1/2 inch overlay?
No. Half overlay usually describes a shared-partition door layout. A 1/2 inch overlay is a measured amount. Always check the hinge diagram and specs.
What is a full overlay cabinet hinge?
A full overlay hinge is used when the door covers most of the cabinet edge or frame. The exact hinge still depends on cabinet type, mounting plate and measured overlay.
Can I replace cabinet hinges without measuring overlay?
It is risky. You may get lucky if you buy the exact same hinge, but for most replacements you should measure overlay, cabinet type, cup diameter and screw positions.
Bottom Line
Measure overlay before buying cabinet hinges. For a centered overlay door, door width minus opening width divided by two gives the overlay per side. Then confirm cabinet type, cup size, mounting plate and opening angle before ordering replacement hinges.
