Area and Volume Calculators: Sq Ft & Cu Yd
Use area and volume calculators for square footage, cubic feet, cubic yards, room area, and bulk material weight.
Square Footage Calculator
Use this square footage calculator to calculate exact area for standard rooms and complex layouts. Supports rectangles, triangles, circles, trapezoids, and L-shaped cutouts with multi-section addition and subtraction.
Cubic Feet Calculator
Use this cubic feet calculator to compute precise three-dimensional volume in cubic feet for rectangular containers, raised planters, and cylindrical columns. Automatically converts between cubic inches, yards, and liters.
Cubic Yards Calculator
Use this cubic yards calculator to estimate bulk material orders in cubic yards for topsoil, mulch, crushed gravel, and ready-mix concrete deliveries. Includes direct depth-in-inches helpers for rectangular areas.
Room Area Calculator
Use this room area calculator and enter lengths and widths in feet and inches to determine floor area, wall surface area, and perimeter moulding measurements for single or multiple connected rooms.
Square Feet to Cubic Yards Calculator
Use this square feet to cubic yards to determine precisely how many cubic yards of bulk material your project requires from surface square footage and target thickness. Whether ordering bulk landscape mulch, topsoil, crushed stone base, or ready-mix concrete, this estimator calculates exact cubic volume and bagged retail equivalents with a dependable subgrade compaction margin.
Cubic Yards to Tons Calculator
Use this cubic yards to tons to convert bulk material volume from cubic yards into total weight in tons and pounds. Quarries and aggregate yards sell heavy gravel, sand, and crushed road base across certified scales by the ton rather than by the scoop. Use this calculator to verify truck payload limits and get accurate delivery quotes.
Trade Guidelines for Dimensions, Area & Volume
Professional tips and standard industry assumptions for accurate material takeoffs and error-free estimating:
Convert All Dimensions to Feet First
When calculating square footage or cubic yards from measurements that include inches, convert inches to decimal feet first (inches divided by 12). For example, 10 feet 6 inches = 10.5 feet. This eliminates compounding rounding errors.
Cubic Volume Formula
Cubic Feet = Length (ft) × Width (ft) × Height/Depth (ft). To convert cubic feet to cubic yards, divide by 27 (since 1 yard = 3 feet, and 3 × 3 × 3 = 27 cu ft per cu yd).
Decomposing Irregular Spaces
For L-shaped, T-shaped, or irregular rooms, sketch the floor plan and divide it into simple squares, rectangles, and right triangles. Calculate the area of each subdivision separately and sum the results.
Bulk Material Weight Approximations
1 cubic yard of dry topsoil ≈ 1.1 tons (2,200 lbs); 1 cubic yard of crushed stone/gravel ≈ 1.4 tons (2,800 lbs); 1 cubic yard of wet sand ≈ 1.5 tons (3,000 lbs); 1 cubic yard of shredded mulch ≈ 0.4 tons (800 lbs).
Frequently Asked Questions: Dimensions, Area & Volume
How do I calculate square feet to cubic yards?
Multiply your total square footage by the project depth in feet (for example, 4 inches depth = 4/12 = 0.333 feet). This gives cubic feet. Then divide that total by 27 to find cubic yards. Example: 300 sq ft × 0.333 ft = 100 cu ft ÷ 27 = 3.7 cubic yards.
How many square feet are in a 10x10 room?
A 10x10 room has exactly 100 square feet of floor area (10 ft × 10 ft). With 8-foot high ceilings, the four walls have a combined gross wall surface of 320 square feet (40 linear feet × 8 ft).
How many cubic feet are in a cubic yard?
There are exactly 27 cubic feet in one cubic yard. A cubic yard is a cube that measures 3 feet long by 3 feet wide by 3 feet tall (3 × 3 × 3 = 27).
How do I convert cubic yards of gravel to tons?
Multiply cubic yards by 1.4 for clean crushed stone aggregate (or by 1.35 for dry gravel). For example, 5 cubic yards of crushed stone weighs approximately 7.0 tons (14,000 lbs).
