Formula or rule of thumb
Example
Use the measured project dimensions, apply the product or layout assumptions, then round to the package or supplier unit.
Common mistakes
Do not hide waste, package coverage, product yield or site assumptions inside one unexplained number.
Planning note: product yields, installation methods, site conditions and local requirements can change the final quantity. Use the exact manufacturer or supplier information before purchasing.
