Practical Guides for Real Homes
Not every home project needs a contractor, a spreadsheet and three cups of coffee. These guides explain what homeowners, DIYers and property owners actually need to know — in straightforward language, with practical examples, and the calculator one click away when you're ready to run your own numbers.
The technical side is still here when you need it — every guide is checked against published industry standards (ASTM, ANSI, TCNA and IRC) and every number in a worked example matches what our calculators produce. But the plain-English answer comes first, the engineering detail second. We don't publish sponsored roundups or product listicles; every article is written to be genuinely useful before a pour, a tile layout or a paint spec.
New guides ship regularly, with roofing, kitchen and bathroom planning, and home maintenance coverage on the way. If there's a topic you want covered, tell us — reader requests shape the calendar.
Field Guide articles are written in imperial units (feet, inches, °F, PSI, gallons) — the standard for US residential construction and the system used by ASTM, ANSI, TCNA, NEC, and IRC. Every calculator on the site supports both imperial and metric: use the Imp / Met toggle in the header to switch, and your preference is saved on this device. Key metric conversions: 1 inch = 25.4 mm, 1 foot = 0.3048 m, 1 gallon = 3.785 L, 1 sq ft = 0.0929 sq m.
