Parquet Flooring Calculator 2026 — Boards & Cost

The amount of parquet is the room area plus a margin for cuts and possible damage. A standard margin is 7–10% for straight laying and 12–15% for herringbone or diagonal laying. For a 25 m² room with an 8% margin you should buy approx. 27 m² of boards.

The margin depends on the laying pattern: straight (classic, parallel) — 7–8%, French or English herringbone — 10–15%, diagonal laying — up to 15%. A larger margin is worthwhile in rooms of complex shape, with alcoves and angles. The margin covers cutting waste and broken boards.

The price of wooden parquet in Poland in 2026 depends on wood species and grade: engineered oak board PLN 120–250/m², solid oak parquet PLN 150–400/m², exotic species PLN 250–800/m². Add the cost of installation (approx. PLN 50–80/m²) plus underlay and skirting boards.

The cost of installing wooden parquet is roughly PLN 50–80/m² for gluing or floating installation. Sanding and varnishing solid parquet adds PLN 40–70/m². Herringbone installation is 20–40% more expensive due to the labour involved. Prices depend on the region of Poland.

Solid parquet is a board made entirely from one wood species — it can be sanded many times but is more expensive and sensitive to moisture. An engineered (three-layer) board has a top layer of fine wood on a stable base — it is cheaper, more dimensionally stable and suitable for underfloor heating.

Yes, but with limitations. An engineered board up to 14 mm thick made of low-expansion wood (oak) works best. Solid parquet and high-expansion species (beech, maple) are not recommended. Keep the floor temperature below 27°C and use a flexible adhesive.

The calculator computes the area with margin, the material (board) cost and the installation cost, and sums them into a total cost. It does not include the cost of underlay, skirting, adhesive, varnish or subfloor preparation (screed, priming). Add these for a full estimate.

The subfloor must be level (deviation up to 2 mm over 2 m), dry (cement screed moisture below 2%) and clean. Gluing requires priming. Floating installation uses a sound-deadening underlay and a vapour barrier film. An improper subfloor is the most common cause of squeaking and detaching parquet.

After gluing parquet, wait 24–48 hours before walking on it and approx. 7 days before full load (furniture). Varnishing requires 2–3 coats with drying between; full curing of the varnish takes approx. 7–14 days. During this time avoid washing the floor and laying rugs.

Floating installation of an engineered board with a click system is possible yourself and saves labour cost. Gluing parquet and sanding require experience and specialist equipment — better left to professionals. Mistakes in glued installation are costly to repair.
