Comment calculer un meuble

The carcase

A cabinet is two sides, a top, a bottom, a back and shelves. Each panel is sized from the overall dimensions minus the thickness of adjoining panels.

Standard dimensions

For a cabinet W wide, H high, D deep, with panel thickness T:

Sides: 2 × (H × D)
Top & bottom: 2 × ((W − 2T) × D)
Back: 1 × ((W − 2T) × (H − 2T))
Shelves: n × ((W − 2T) × D)

Doors and drawers

Doors: (W / n) − gap wide × full height. Drawers need slides with their own clearances — see the drawer guide.

Practical tips

• 18 mm is the standard carcase thickness.
• Leave 2–3 mm gaps between doors.
• Plan shelf heights around what you will store.
