About Tradesman Math

Every calculator on this site is built from published engineering tables and code requirements (IRC, IBC, manufacturer specs), then checked against known examples. Where a number affects safety — stairs, spans, footings — the tool tells you the code rule and says to verify locally.

The site is deliberately boring: fast pages, honest math, and tools that answer the question you actually asked.

It's run by a small independent team — no parent company, no sales team, no dark patterns. We ship a new tool only when its math is verified against a real source, and we read every correction that comes in. Found something wrong? Tell us — with your local code reference, that's the fastest fix we can make.
