Rectangular sheet nesting

Place rectangular parts on sheets and see sheet requirements and material utilisation.

How to use

Calculation inputs

Each row: width × height × quantity. Example: 400 x 300 x 5. Decimal point; up to 200 pieces.

Calculation result

Enter the values; results update automatically.

Up to 200 parts; guillotine-split heuristic with no optimality guarantee. Kerf area follows this cut model. Grain, tabs and thermal effects are excluded.

How to use

Enter sheet dimensions, margin on all four edges, kerf and rectangle list. Optional rotation is 90°. Area totals separate parts, margins, kerf and remnants.

Example calculation

1000 × 1000 mm; m = k = 0; 500 × 500 × 4 → n = 1; η = 100%.

Calculation method

A = Ap + Am + Ak + Ar η = Ap / A × 100%

Calculation limits

Up to 200 parts; guillotine-split heuristic with no optimality guarantee. Kerf area follows this cut model. Grain, tabs and thermal effects are excluded.
