Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

  • Parquet block count = ceil((floor area ÷ block area) × (1 + waste allowance)), the same coverage method used for tile, applied to standard square parquet blocks

Frequently asked questions

How big is a standard parquet block?
A common size is around 300x300mm (0.09 m² per block), but parquet blocks are made in a range of sizes and patterns (herringbone, basketweave, and others) — always confirm the exact face area of your chosen product before ordering.
Why is the waste allowance higher than for large-format tile?
Parquet blocks are smaller and are often laid in patterned arrangements, which generates more perimeter cuts and offcuts per square meter of floor than a single large tile or plank would.
Does this include blocks for a border or feature strip?
No — this estimates the field (main floor) block count only. Add a separate quantity if your design includes a contrasting border, medallion, or feature strip around the room's perimeter.
