Suggest a calculator
The most useful additions to Tupep have come from reader suggestions. If there’s a home or yard project you keep re-calculating by hand, tell us about it — include the material, the units you work in, and anything that makes the estimate tricky (waste, patterns, odd shapes), and we’ll look into building it.
Corrections
Accuracy matters to us. If you believe a formula, coverage rate, or assumption on any page is wrong, please include the page link and the source you’re comparing against, and we’ll review it promptly.
Note: Tupep provides material estimates for planning purposes. For structural work, always consult a licensed contractor and your local building codes.
