When to use this calculator
- Calculating how many cabinet shelves (e.g., 900 mm × 300 mm) can be cut from a single 4×8 melamine sheet before ordering material for a kitchen remodel.
- Estimating total sheet count and cost for a closet organizer with multiple shelf panels cut from 3/4" white melamine particleboard.
- Planning a woodshop project where students maximize the number of 400 mm × 250 mm parts from a shared 2.44 m × 1.22 m panel with minimum waste.
- Determining whether to purchase full sheets (2,440 × 1,220 mm) or half sheets (1,220 × 1,220 mm) based on the longest piece required for the job.

How it works
How It's Calculated
The calculator uses a guillotine-cut (strip-cut) layout — the standard approach on a panel saw, table saw, or track saw. It tries both piece orientations and picks the one that fits more pieces:
// Orientation A: piece length along the board length
Columns_A = floor(Board_Length ÷ (Piece_Length + Kerf))
Rows_A = floor(Board_Width ÷ (Piece_Width + Kerf))
Pieces_A = Columns_A × Rows_A
// Orientation B: piece rotated 90°
Columns_B = floor(Board_Length ÷ (Piece_Width + Kerf))
Rows_B = floor(Board_Width ÷ (Piece_Length + Kerf))
Pieces_B = Columns_B × Rows_B
// Best layout
Pieces_per_board = max(Pieces_A, Pieces_B)
// Area and yield
Piece_Area = Piece_Length × Piece_Width / 1,000,000 (m²)
Board_Area = Board_Length × Board_Width / 1,000,000 (m²)
Used_Area = Pieces_per_board × Piece_Area
Yield_% = (Used_Area / Board_Area) × 100
Waste_m² = Board_Area − Used_Area
// Total boards for the full job
Boards_needed = ceil(Total_Pieces / Pieces_per_board)Saw Kerf
A standard triple-chip carbide blade for melamine has a kerf of 3.2 mm (⅛"). Industrial beam-saw blades can be as narrow as 2.5 mm; a general-purpose circular saw blade may reach 4 mm. For a board with 8 rip cuts, total kerf loss is 8 × 3.2 mm = 25.6 mm — enough to lose an entire row of pieces if ignored. Default value in this calculator is 3 mm.

Common Errors
1. Ignoring saw kerf: Forgetting the 3 mm kerf per cut causes the last piece in a row to be undersized or not fit at all, ruining an entire board. Always subtract kerf.
2. Ignoring grain direction: Melamine with a wood-grain print is directional. Rotating pieces 90° to improve yield may reverse the grain direction, which is visible and unacceptable on finished cabinet doors or shelf fronts. Grain constraints can reduce piece count by 20–40% versus non-directional melamine.
3. Confusing piece area total with sheet count: The sum of piece areas is never directly equal to sheets needed, because offcut shapes don't perfectly nest. Always use the piece-per-board formula.
4. Forgetting edge banding: Cut melamine edges expose raw particleboard and must be edge-banded (PVC or ABS tape, 0.4–2 mm thick). Edge-banding adds a small amount to the finished piece dimension — account for this in your final piece measurements.
Example: 900 mm × 300 mm kitchen shelves from a 2,440 × 1,220 mm board
