Overlay doors sit on top of the cabinet frame and cover part of it, while inset doors fit completely inside the cabinet opening. Overlay is more common and forgiving for installation.
Partial overlay (0.5") is standard for traditional cabinets, while full overlay (1.25") gives a more modern look. The overlay determines your hinge type and affects the door size calculation.
A reveal of 0.125" (1/8") is recommended for most installations. This provides enough clearance for smooth operation while maintaining a clean appearance.
Yes, this calculator determines the overall door dimensions regardless of panel style. The calculations work for any cabinet door type including raised panel, flat panel, and Shaker styles.
If you're replacing doors and keeping the same hinges and overlay, you can simply measure your existing doors. Otherwise, measure the cabinet opening and use this calculator for accurate sizing.
Measure the inside width and height of the cabinet frame opening to the nearest 1/16". Take measurements at multiple points as openings may not be perfectly square.
For double doors, a gap of 0.125" between doors is standard. This allows for proper operation and accounts for any slight variations in installation or wood movement.
The basic door sizing remains the same regardless of wood species. However, some woods expand and contract more than others, so you may want slightly more clearance for solid wood doors in humid climates.
