Vertical Depth from a Slope Percentage and Horizontal Length

Sometimes all you know is the slope in a percentage (SP) and the horizontal length (HL) of the excavation. Knowing the vertical depth or height (VH) will enable you to estimate the amount of materials you get from the excavating with these measurements.

Vertical Depth from a Slope Percentage and Horizontal Length

Formula: VH = HL * (SP ÷ 100)

Example calculation

horizontal length = 14' 1"
slope percentage = 33.3%
convert feet to inches
14 * 12 + 1 = 169"
169 * (33.3 ÷ 100)
169 * 0.333 = 56 (rounded) = 4' 8"
The vertical height of this excavation is 4' 8"
