Calculateur de Caisson de Tiroir & Jeu de Coulisse

How to use it: enter the cabinet opening width, your slide's nominal length, and your material thickness and clearances. This models a "captured" drawer box: two full-depth side panels, with the front and back panels fitted between them, and a bottom panel set into a groove inset from all four edges - the most common shop-built drawer box construction.

Formula.

Box width = opening width − total side clearance
Box depth = slide length − depth setback
Front/back length = box width − 2 × side thickness
Bottom width = box width − 2 × bottom inset, Bottom depth = box depth − 2 × bottom inset

Worked example. With the defaults (450 mm opening, 450 mm slide, 25 mm depth setback, 13 mm total side clearance, 12.7 mm side thickness, 6 mm bottom inset): box width = 450 − 13 = 437 mm; box depth = 450 − 25 = 425 mm; front/back length = 437 − 2×12.7 = 411.6 mm; bottom = (437 − 2×6) × (425 − 2×6) = 425 × 413 mm.

This models one common construction method - a captured box with an inset-groove bottom - not every drawer-box style. Applied (screwed-on) bottoms, dovetailed boxes, and overlay drawer fronts mounted proud of the box all change these numbers. It does not model a specific hardware manufacturer's published clearance chart; side clearance and depth setback vary meaningfully between undermount, side-mount, and different slide series, so treat the defaults as a starting point and confirm against your actual slide's installation instructions.

Drawer box height here is a direct input, not derived from the cabinet opening height - how much of the opening height a drawer box actually uses depends on face-frame or frameless construction, top/ bottom rail width, and reveal gaps, which this tool does not model.
