• Estimating underlay and trim quantities.
• Costing a flooring project.

Flooring Calculator: limits and things worth knowing

• Divide the area by the pack coverage and round up to whole packs, then add 5-10% for cuts. Complex room shapes and diagonal lays need more.
• Order from a single batch for consistent colour and finish, and keep a spare pack for later repairs — ranges are discontinued frequently.
• Laminate and engineered boards need an expansion gap around the perimeter, typically 10-12 mm, which is covered by the skirting or beading rather than filled.
• Underlay is usually sold separately and by a different coverage figure; do not assume the two match.

Is it private and secure?

Your privacy is built in. Flooring Calculator runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
