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 references, 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.

The library now runs to fifty guides across ten categories — including a new Homes Around the World collection on how homes are built and measured in Japan, China, the UK, South Africa and beyond, and new clusters for pools, ponds, masonry and stairs. If there's a topic you want covered, tell us — reader requests shape the calendar. If there's a topic you want covered, tell us — reader requests shape the calendar.

A note on units

Guides are written for both unit systems — metric first, imperial alongside where the trade still uses it. Every calculator defaults to metric: use the Met / Imp toggle in the header to switch, and your preference is saved on this device. Regional standards differ: building codes, timber sizes, bag sizes and practices vary by country, so where a guide cites one, it names it.

Concrete Guides

Estimating, mix design, thickness, reinforcement, and curing — the full concrete cluster, anchored by the Concrete Slab & Footing Calculator.

Drywall & Wall Guides

Board selection, fasteners, compound quantities, and finish levels — everything around the Drywall Sheet & Screws Estimator.

Tile & Flooring Guides

Takeoffs, layout patterns, grout, and joint width — the tile guides behind the Tile Layout & Mortar Calculator, plus the plank-floor quantity guide.

Paint Guides

Quantities, sheen, primer, and coats — the decisions that surround the Paint & Primer Coverage Calculator.

Garden & Outdoor Guides

Volume math, depth by application, mulch vs. stone — and the deck lumber takeoff, from joist spans to screw counts, behind the Mulch and Deck Lumber calculators.

Roofing & Solar Guides

Measurement-first guidance for the top of the house — roof area and squares, the panel count and system size that follow from it, and the vent area an attic needs, anchored by the Roofing Materials and Solar Panel Sizing calculators.

Home Maintenance Guides

The measurement problems behind quiet emergencies — service capacity, wire sizing, hot water, drains, the thermal envelope, and the water standing in your pipes — explained with worked examples, with four calculators now live beside them.

Pool & Pond Guides

Water is heavy, awkward and worth measuring twice — volumes, fill times, liners and pump flows, with the safety notes that belong around water.

Workshop Guides

The hardest-working room of the house — light levels, circuits and the planning that keeps a workshop usable.

Regional Planning Guides

The calculators are global; the context is local. How homes are built, measured and renovated in different countries — and what it changes about your planning.

Editorial Note

The Field Guide is intentionally narrow. We publish fewer articles than a typical home-improvement blog, but each one is meant to be a definitive reference you can rely on — and hand to your contractor with confidence. If a topic is missing, request it via the contact form — we read every message.
