Cabinet Material Calculator

This calculator breaks a single cabinet box down into its component panels and sums the plywood area each one needs, then scales that by how many identical cabinets you're building. It assumes a standard six-panel box: two side panels (depth × height each), a top and bottom (width × depth each), one back panel (width × height, even though backs are often thinner 1/4" stock, the sheet-goods area still counts), and one shelf sized slightly smaller than the interior opening (width minus 1.5" and depth minus 0.5", accounting for face-frame or side-wall thickness). All of that per-cabinet area is multiplied by your cabinet count, then divided by usable sheet area to get sheets needed — a full 4×8 sheet is 4,608 square inches, but this calculator only counts 85% of that as usable, building in a realistic waste factor for cut-offs, grain direction, and defects, then rounds up since you can't buy a partial sheet.

Edgebanding is calculated separately and only covers the front-facing edges that would actually show on a finished cabinet: both side heights, both the top and bottom widths, and the shelf's front width (2H + 3W per cabinet), converted from inches to feet. Keep in mind this models one standard cabinet configuration — it doesn't account for face frames, doors, drawer boxes, adjustable shelf pins, or multiple shelves per cabinet, all of which add their own material on top of this box-only estimate, so use the sheet count here as your carcass material baseline and add separately for doors, drawer fronts, and any extra shelving.
