Architecture & Construction Calculators
Calculators for material quantities and building measurements.
Turning a design into a finished building depends on getting quantities right — how much material a pour or a paint job actually requires, measured precisely enough to order the right amount without excessive waste. This category covers the calculations behind those quantities, useful for architects, contractors, and anyone planning a construction or renovation project.
Concrete Calculator
Calculate the volume of concrete needed for slabs, footings, and columns, plus an estimate of premixed bags required, in both US and metric units.
Paint Calculator
Calculate how much paint you need for a room's walls and ceiling from its dimensions, number of coats, and your paint's coverage rate.
Staircase Dimension & Code Compliance Calculator
Calculate the exact number of risers, treads, and total run for a staircase from its floor-to-floor height, and check the result against common US residential (IRC) and commercial (IBC) building code thresholds.
ADA Ramp Run & Landing Calculator
Calculate the exact ramp length needed for a given vertical rise at a chosen slope, the number of level landings required, and check the result against the ADA Standards for Accessible Design (2010).
