Engineered wood flooring calculator
Enter your room size and this calculator turns it into m² and whole packs of engineered wood, with a waste allowance that matches your laying pattern. Engineered boards are the most expensive flooring this calculator covers, so the waste percentage matters most here.
Engineered packs commonly cover between 1.5 and 2.2 m², and wide-board ranges sometimes less. At €40 to €80 per m², two packs of over-ordering costs real money, and under-ordering risks a batch mismatch in visible grain.
This is the estimate. The designer lays out every board in your actual room, so the pack count comes from real cuts, not a flat percentage.

If the room width is an awkward multiple of the board width, the last row becomes a thin rip and its offcut is pure waste. With boards of 220 mm or more this can quietly add several percent, so a layout planner catches it before you order.
Grain matching means less reusable offcut
Unlike laminate, visibly different grain means you cannot always start a row with any offcut. Sit at the upper end of the waste range if the range has strong grain variation.
Solid wood is different
Solid hardwood has to run perpendicular to the joists when it is nailed down, which can force the layout direction and change the waste. This calculator assumes floating or glued engineered boards.
Frequently asked questions
- How much waste should I allow for engineered wood flooring?
- Allow 8% to 12% for a straight lay, using the higher figure for rooms with alcoves or angles, 10% to 15% for a diagonal lay, and 15% to 20% for herringbone or chevron. Strong grain variation pushes you to the top of each range, because fewer offcuts are reusable.
- How many packs of engineered wood for a 25 m² room?
- With 10% waste you need 27.5 m². At a pack coverage of 1.9 m² that is 27.5 ÷ 1.9 = 14.5, so 15 packs. Check your exact pack coverage, because engineered ranges vary widely.
