How the calculation works
Curb volume = run length × rectangular section width × section height.
A worked example
A 60 ft run at 6 × 8 in measures 20 ft³, or 0.7407 yd³, before allowance.
What to check before using the result
- Gutter pans, battered profiles, channels and rolled curbs need their own cross-sectional areas.
- This tool does not claim a highway or drainage standard.
