About MeasureShed
MeasureShed is a set of free calculators for planning property projects. Every tool shows its formula, cites its sources, and prints a clean material list. No accounts, no paywalls.
Formulas come from published standards (IRC, ACI, AWC, manufacturer specs) and are reviewed before a calculator ships. The exact math is printed on each page — the same numbers the tool computes.
Advertising, in three fixed slots that never sit between your inputs and your results. We don’t sell leads, and we don’t accept placement that imitates calculator UI.
Results are planning estimates, not engineering advice. Building code requirements vary by jurisdiction; confirm dimensions, spans, and load requirements with your local code office or a licensed professional before you buy materials or cut lumber.
