ARKITECTRUE
Architecture, design, and the art of building well.
From room dimensions and material take-offs to roof pitch, build cost, energy efficiency, and sustainable design, ArkitecTRUE pairs free hands-on architecture calculators with practical guides and a richly illustrated museum. Design smarter and build better.
Architecture Calculators & Tools
Free tools for architects, builders, and homeowners — room dimension calculator, material coverage calculator, roof pitch calculator, building cost estimator, energy efficiency analyzer, and sustainable design score.
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
Architectural Styles & Iconic Buildings Museum
Wander an immersive museum of the built environment — the great architectural styles from Gothic to Modernism, the world's most iconic buildings and landmarks, and the building elements that define them, each with its own gallery so you can understand what shapes a building's character and what makes great design endure.
Tour the museum →From the Journal
Fresh guides on architectural styles, residential and modern design, sustainable building, landscape architecture, interior design, and urban planning.
