Estimates only

All calculators on DIYCalcs provide estimates for planning purposes. Results depend on the accuracy of your measurements and on assumptions such as product coverage, material density and waste. Actual quantities can differ. Always verify quantities with your supplier, follow product instructions and comply with local building codes.
