Get an optimized cutting layout for medium-density fibreboard sheets. Less wasted material, fewer trips to the lumber yard.
Open the Optimizer →MDF is heavier and more expensive per square foot than plywood, and every wasted offcut means extra dust, extra weight to dispose of, and a bigger hole in your budget. Standard MDF panels in North America run 4×8 ft (49×97 in nominal); in Europe, 2440×1220mm and 2800×2070mm are typical. Sheets are dense — a single 18mm 4×8 panel weighs around 95 lb (43 kg), so reducing the number of sheets you have to lift is reason enough to optimize.
Our cut calculator runs a 2D bin-packing algorithm with rotation, kerf compensation, and waste reporting. Enter your panel size, paste in a parts list, and the tool returns the cutting diagram and total sheet count. Free, no signup needed.
| Panel | mm | inches |
|---|---|---|
| Standard (US) | 2440 × 1220 | 96 × 48 |
| European wide | 2800 × 2070 | 110 × 81 |
| Half-sheet | 1220 × 1220 | 48 × 48 |
| Long panel | 3050 × 1220 | 120 × 48 |
Use a higher tooth count blade. 60+ tooth ATB or TCG blades give cleaner edges in MDF and produce finer dust that's easier to control with a vacuum.
Plan kerf carefully. MDF doesn't tear out, but a 3.2mm kerf still adds up — on a 30-part cabinet job, that's 90mm of board you've sawdusted. Set kerf accurately in the optimizer.
Keep sealable offcuts. Bare MDF edges drink in moisture and swell. If you're saving a remnant for a future project, store it flat and edge-seal with primer.
Wear a respirator. MDF dust contains urea-formaldehyde resin. Cut outdoors when possible, or hook a HEPA-rated vacuum to your saw.
Consider grain direction. MDF is isotropic so rotation is always safe — unlike plywood, you don't lose strength when a panel runs the "wrong way." Let the optimizer rotate freely.
