CalcCommonsConstruction & Measurement Calculators
Start with measurements, convert units, and estimate materials for a home or outdoor project.
Area & volume
Area is measured in square units; volume adds a depth and uses cubic units. Use Area for individual shapes, Square Footage for multiple rooms, and Volume for geometric solids.
Square Footage Calculator
Add room areas and quantities, convert square units, and estimate cost per square foot.
Area Calculator
Calculate the area of six geometric shapes with conversions to common square units.
Volume Calculator
Calculate prism, cube, cylinder, sphere, and cone volumes in cubic units, liters, and US gallons.
Yards & landscaping
For a bed or path, measure length and width separately from depth. Cubic Yard gives the geometric volume. Gravel estimates weight using a density; Mulch converts volume to whole bags.
Gravel Calculator
Estimate gravel volume and approximate weight from dimensions, density, and waste allowance.
Cubic Yard Calculator
Convert a rectangular bed, round bed, or known area and depth into cubic yards.
Mulch Calculator
Estimate mulch in cubic yards and bags for a rectangular bed, round bed, or measured area.
Concrete planning
Slabs, pads, footings, and walls share a rectangular-volume calculation. Round columns use a cylinder. Concrete Calculator adds quantity, waste, bag-yield estimates, and an optional unit price. Verify product specifications and structural requirements before ordering.
