Curb and Gutter Concrete Yardage Calculator

This calculator estimates the volume of concrete in cubic yards required for a curb and gutter barrier. By entering the length, face width, gutter width, and curb height (in inches), you can accurately determine how much concrete is needed for construction.

Curb and Gutter Yardage Formula

Formula
$$\text{Yardage} = \left[ l \cdot \left( \frac{f}{12} \cdot \left( \frac{g}{12} + \frac{h}{12} \right) \right) + l \cdot \left( \frac{h}{12} \cdot \frac{h}{12} \right) \right] \cdot 0.037037$$

Where:

  • $$l$$ — total length of the barrier (feet)
  • $$f$$ — face width (inches)
  • $$g$$ — gutter width (inches)
  • $$h$$ — height of curb (inches)
  • $$0.037037$$ — conversion factor from ft³ to yd³


This formula combines the gutter and curb volumes into a single estimate. All dimensions are converted from inches to feet before the final volume is converted to cubic yards. Ideal for civil engineers and contractors working on sidewalks, roads, and parking lots.
