Calculator results

All calculator results are estimates for planning purposes only. They are not guaranteed to be accurate for your specific project. Actual material quantities will depend on site conditions, product specifications, installation methods, ground conditions and many other factors.

You should always verify quantities with your supplier, and consult a qualified professional for any structural, safety-critical or regulated work.

No professional advice

Nothing on this site constitutes professional engineering, building regulation, structural or construction advice. We are home DIYers sharing planning tools. We are not engineers, surveyors, architects or qualified tradespeople.

Accuracy and errors

While we take care to use reasonable planning figures and flag our assumptions clearly, we make no warranty that the calculations are error-free. If you spot something that seems wrong, please contact us.
