MDF cut list optimizer
A clean sheet is the expensive part of the story.
This free MDF cut list optimizer turns finished cabinet parts into a kerf-aware sheet layout before the board is lifted onto the bench. Enter the stock you can buy, the rectangles you need, and the allowances your saw will consume; then inspect what fits and what still needs a decision.
Live MDF cut list optimizer
Give every panel a place before the sheet reaches the bench.
Start with the cabinet example, then replace each row with your own rectangular parts. The plan accounts for sheet size, outside margin, blade kerf, quantity, and rotation.

This is a geometric nesting layout, not an automatic table-saw cut sequence. Review support, defects, finish faces, tooling, and safe handling before cutting.
Read the plan
The sheet count is the answer. The layout is the evidence.
Area can estimate a theoretical minimum, but it cannot prove that wide shelves and tall sides share the same rectangle. The layout tests actual dimensions with the main Free Nesting engine, preserves kerf and margin, and keeps unplaced parts visible. Use the MDF cut list optimizer to follow that evidence instead of trusting area alone.
Yield divides finished part area by the sheets used. “Waste” is the remainder, not a claim that it is unusable. A clean rectangle may be a useful offcut; a damaged strip may not.
Follow one sheet
Four decisions carry the MDF cut list from drawing to bench.
The page stays useful by following the material in order. Each decision adds a physical fact the previous one could not know.
01
The drawing becomes finished rectangles.
Name each side, shelf, deck, rail, and door, then enter finished width, height, and quantity. Names keep similar rectangles identifiable.
02
The sheet introduces real boundaries.
Match purchasable stock, reserve any edge-trimming margin, and add measured blade kerf separately. Finished dimensions stay finished.
03
Rotation opens another arrangement.
Plain MDF often permits 90-degree rotation. Veneered, routed, finished, or matched faces can remove that freedom.
04
The result becomes a question you can inspect.
Read sheet count, yield, waste, and unplaced parts, then trace the labels. The operator still decides handling and safe setup.
MDF-specific judgment
Uniform material still arrives as a particular board.
An MDF sheet cutting optimizer can model rectangles precisely. It cannot see the face, edge, weight, dust, or shop around them.
Separate thickness from the two-dimensional layout.
The nest uses width and height and assumes compatible stock. Confirm thickness, grade, moisture resistance, and finish before grouping rows; a perfect layout is wrong if a part needs another panel.
Put cutting loss in the rules, not inside the part.
Enter finished sizes, measure kerf on scrap, and reserve margin only where stock will be trimmed. Paint gaps, profiling, sanding, or tabs belong in the dimensions or production process.
“No grain” does not always mean “no direction.”
Plain MDF is comparatively uniform, so rotation often improves packing. Veneer, laminate, routed patterns, finished faces, edge-banding, and matched doors can restore direction.
Plan handling and dust control outside the diagram.
Full MDF sheets are awkward to support and create fine dust. Follow board, tool, extraction, and protective-equipment guidance. The planner cannot certify a machine setup or make a cut safe.
From one sheet to the next
The free plan solves this sheet. Pro removes the setup from the next one.
The MDF cut list optimizer keeps calculation free. Upgrade only when remembered projects, shop defaults, reusable parts, offcuts, and production handoff would make repeated work faster.
Calculate, inspect, and continue without an account.
Carry this cut list into the full workspace, compare modes, and use standard exports. The useful result stays free.
Reuse the workshop knowledge around the layout.
- Saved projects and cross-device history
- Material, part-kit, offcut, CSV, and shop-profile libraries
- Cost-aware labels and production packets
Same planning engine. Pro does not buy a better packing result; it reduces repeated setup, lookup, and handoff work.

Practical questions
MDF cut list optimizer FAQ
What does an MDF cut list optimizer calculate?
It places rectangular finished parts on MDF sheets after kerf, margin, quantity, and rotation are defined. The result reports sheet count, yield, waste, unplaced parts, and labeled positions; it does not replace a safe workshop plan.
Can MDF parts rotate freely?
Plain MDF has a uniform core, so undecorated parts can often rotate. Lock orientation when a face is veneered, finished, routed, matched, damaged, or tied to edge treatment. The actual board decides the rule.
Should I add blade kerf to every part dimension?
No. Enter finished part dimensions, then add measured kerf once as a cutting constraint. Enlarging every part counts the allowance twice. Test the blade, machine, and MDF because nominal width may differ from effective kerf.
Does the layout tell me the order of cuts?
The free nesting result proves geometric placement, not cut order. When every cut must cross the current sub-sheet, compare the job in the Guillotine Cutting calculator and review its sequence against your equipment and handling limits.
The board is still whole. Make the next decision visible.
