🗄 Drawer Reveal Calculator

Determines exact drawer face dimensions, equal reveals, and box sizes for any cabinet type. Consistent reveals are the mark of professional cabinet making — unequal gaps are immediately visible and indicate amateur work. Covers all major slide systems and cabinet construction types.

Formulas

Face height (N equal): FH = (OH - bot_reveal - reveal x (N+1)) / NFace width (frameless): FW = OW - 2 x revealBox width (undermount): BW = OW - 3mmBox width (side-mount): BW = OW - 2 x slide_clearanceY position (drawer n): Yn = bot_reveal + (n-1) x (FH + reveal) + reveal

FAQ

What is a "reveal" in cabinet making?

The visible gap between adjacent drawer faces (or face and cabinet edge). Standard: 3mm for European frameless; 3–5mm for face-frame; 2mm for high-end inset. Consistent equal reveals across all drawers is the mark of quality craftsmanship.

Blum Tandem box width calculation?

Box width = Opening width − 3mm (1.5mm each side). The slide mounts underneath, so no side clearance needed for hardware. For Blum Legrabox: same formula. Always verify with the specific slide's installation instructions.
