FREE CALCULATORS.
NOW WITH AR.

Measure linear feet with your phone camera, save the result locally, and use it in a bid.

Walk four corners to capture square footage, perimeter, and saved area results.

Capture length, width, and depth to calculate cubic feet and cubic yards for material orders.

Use your phone tilt sensor to capture pitch, degrees, ratio, and roof slope factor.

Snap a jobsite photo, pin dimensions, save the result locally, and keep field notes organized.

Fast cooling-load sanity check (BTU/h + tons) — not a full ACCA Manual J.

Plug in square footage, get a defensible labor estimate by trade.

Diameter-at-breast-height in, climbing + rigging hours out.

PVWatts-style annual production from system size, tilt, and azimuth.

Length × width × average depth → gallons + chemical baseline.

Translate markup % to margin % (and back) without the math mistakes.

Sqft to squares to bundles, with waste factor by pitch.

Wall + ceiling area → sheets, mud, tape, screws, hang + finish hours.

Slab L × W × thickness → cubic yards, rebar pounds, form linear feet.

Wall area minus openings × coats → gallons, prep cost, labor hours.

Perimeter and post spacing → posts, pickets, rails, concrete bags.

Patio area → pavers, base + sand cubic yards, edge restraint, polymeric sand.

Area × surface difficulty → hours, water + detergent, defensible sell price.
