Need to know how to measure cubic feet? This guide explains how to calculate cubic feet (cu ft), a key imperial unit for measuring volume. Cubic feet are used for spaces like rooms, storage units, or appliances, calculated by multiplying length, width, and height in feet.
Explore our cubic feet measurement guide, use our free calculator, and check practical examples to master volume calculations for construction, shipping, or home projects.
Key Fact: Cubic feet = length (ft) × width (ft) × height (ft). Example: A 2 ft × 3 ft × 4 ft box = 24 cu ft.

Cubic Feet Measurement Examples
Understand how to figure cubic feet with common scenarios:
| Dimensions (ft) | Cubic Feet (cu ft) | Practical Example | Use Case |
|---|---|---|---|
| 1 × 1 × 1 | 1 | Small storage cube | Packaging |
| 2 × 2 × 2 | 8 | Medium moving box | Relocation |
| 2 × 3 × 4 | 24 | Microwave oven | Appliance sizing |
| 5 × 5 × 2 | 50 | Small storage unit | Self-storage |
| 10 × 10 × 8 | 800 | Small room | HVAC calculations |
| 20 × 20 × 10 | 4000 | Large shipping container | Freight transport |
Cubic feet = length × width × height (in feet). Use inches to feet or read tape measurements for related tools.
How to Measure Cubic Feet: Key Tips
What is it? Cubic feet measure volume by multiplying length, width, and height in feet. It’s used in the US for spaces like refrigerators, rooms, or cargo. Example: A 2 ft × 3 ft × 4 ft box = 24 cu ft.
Common Mistake: Using inches without converting to feet—divide each dimension by 12 first (e.g., 24 in = 2 ft). Learn more at Inches to Feet.
How to Calculate Cubic Feet
Calculation Formula
Cubic Feet: cu ft = length (ft) × width (ft) × height (ft)
If using inches: cu ft = (length ÷ 12) × (width ÷ 12) × (height ÷ 12)
Standard volume formula for construction, shipping, and storage.
Step-by-Step Example
Measure Dimensions
Measure length, width, height in feet (e.g., 2 ft × 3 ft × 4 ft).
Calculate Volume
Multiply: 2 × 3 × 4 = 24 cu ft.
If Using Inches
Convert inches to feet (e.g., 24 in ÷ 12 = 2 ft), then multiply.
