Parquet flooring calculator
Engineered and solid wood flooring is sold by the pack, like laminate, but the packs are usually smaller and the boards more expensive — so ordering the right number of packs matters more. The method is the same: net area, plus cutting waste, divided by the coverage per pack and rounded up.
The calculator also estimates the underlay and the skirting, which are easy to forget when ordering.
Your measurements
Printed on the pack label — usually 1.5–2.5 m².
Result
- Net floor area
- 12.00 m²
- Area incl. waste
- 12.84 m²
- Packs to buy
- 6 pcs
- Area you will buy
- 13.32 m²
- Underlay (net area + 10%)
- 13.2 m²
- Skirting boards (perimeter − doors + 5%)
- 13.8 m
Leave the flooring in the room for about 48 hours before fitting so it adjusts to the temperature and humidity.
How the calculation works
- Net area = length × width, minus areas permanently covered (fitted wardrobes, kitchen units).
- Area to order = net area + waste: 7% for a straight layout, 12% for a diagonal layout or a room with many corners.
- Packs = area to order ÷ coverage per pack (from the label), rounded up.
- Underlay = net area + 10%; skirting = perimeter − door openings + 5%.
Worked example
For a 4 × 3 m room (12 m²) with 7% waste you need 12.84 m². With packs of 2.22 m², that is 12.84 ÷ 2.22 = 5.8, so 6 packs — 13.32 m² in total, with a small reserve.
What the calculator assumes
- The calculation is the same for engineered, solid and laminate flooring; only the coverage per pack changes (roughly 1.5–2.5 m²).
- 7% waste covers cutting the row ends; herringbone and diagonal layouts need much more.
- Thresholds and skirting are not part of the floor area.
When to adjust the result
- Leave the flooring in the room for about 48 hours before fitting so it acclimatises to the temperature and humidity.
- Solid wood laid on a screed needs the screed to be dry; the maximum residual moisture is in the manufacturer's instructions.
- Glued-down wood floors need adhesive calculated separately, from the coverage on the adhesive bucket.
Frequently asked questions
Floating or glued parquet?
Floating floors are quicker to fit and easier to replace; glued floors feel more solid underfoot, transmit less footstep noise and work better with underfloor heating. The flooring manufacturer says which methods each product allows.
How much extra parquet should I order?
About 7% for a straight layout, 10–12% for diagonal layouts or rooms with many corners, and more for herringbone. Keep a spare pack from the same batch for repairs.
