Home & Building
Sizing and take-off calculators for the house itself: paint, tile and plaster quantities, concrete and rebar, AC and heating capacity, water heaters and pipe sizes, wire gauge and solar panels, decking, stairs and cabinet cuts. Imperial units, US codes, and the metric equivalent alongside every number.

Count deck boards and fasteners, get the best cut yield from a 4 × 8 sheet, lay out stair risers and treads to IRC limits, and size hinges, screws and window profile — all in inches and feet.
5 calculadoras How much concrete, steel and brick does this take?Size a strip footing, a spread footing, a beam and a masonry wall, and get the concrete in cubic yards, the premix bags, the rebar weight and the brick count — with the imperial conversions of every constant shown.
5 calculadoras How much paint, tile and plaster do I buy?Work out gallons of paint, boxes of tile, cubic feet of plaster, rolls of membrane and feet of baseboard from one set of room dimensions — with the waste allowance and the whole-unit rounding already applied.
6 calculadoras What size AC, heater and vent fan does this room need?Size the air conditioner in BTU/h and tons, the heater in BTU/h and kW, the exhaust fan in CFM and the wall insulation in R-value, from one set of room dimensions — using ENERGY STAR, ASHRAE 62.2 and IECC figures.
4 calculadoras What size water heater, tank, pipe and pump do I need?Size a water heater in gallons or GPM, a storage tank, the supply pipe diameter in inches, the pump in horsepower and the drain and trap size — using DOE first-hour ratings and IPC minimums.
5 calculadoras What wire gauge, what breaker, and how many solar panels?Size branch circuit wire and breakers from NEC Table 310.16 ampacity and voltage drop, work out how many solar panels your bill needs, and calculate the capacitor for power factor correction.

Five take-offs that share the same dimensions. Switch between them without retyping the job.
Datos para la cuenta: Deck length or window width (ft), Deck width or window height (ft), Board face width (in).
Referencia: International Code Council.
Preliminary sizing rules and material take-offs. The dimensions you enter carry across all five, so you can walk the whole structure without retyping.
Datos para la cuenta: Length or clear span (ft), Width (in), Depth or thickness (in).
Referencia: International Code Council.
Same room, five different shopping lists. The dimensions stay put; only the coverage rule changes.
Datos para la cuenta: Room length (ft), Room width (ft), Ceiling height (ft).

The same room drives all four numbers. Switch between them without retyping anything.
Datos para la cuenta: Room length (ft), Room width (ft), Ceiling height (ft).
