Architecture Calculators & Tools
Free, practical tools for architects, builders, and homeowners — size up a room, count materials, work out roof pitch, estimate build cost, analyze energy efficiency, and score a design's sustainability.
Room Dimension Calculator
Turn a room's length, width, and height into floor area, perimeter, wall area, volume, and the paint needed to coat the walls
Material Coverage Calculator
Work out how many gallons, boxes, or bags you need to cover an area, with a wastage allowance built in so you never run short
Roof Pitch Calculator
Convert a roof's rise and run into its slope angle, slope factor, and the standard rise-per-12 pitch ratio used on drawings
Building Cost Estimator
Get a rough construction budget from floor area, a per-square-foot rate, stories, and a basic, standard, or premium finish
Energy Efficiency Analyzer
Score a building 0–100 from its insulation, window performance, HVAC rating, and air sealing, with a letter band and sub-scores
Sustainable Design Score
Rate a design on renewable energy, recycled materials, water efficiency, and passive and green-design features from 0 to 100
