Enter the depth of the deep end, the depth of the shallow end, and the length of the slope into the calculator to determine the slope of a pool.

Pool Slope Formula

The following formula is used to calculate the slope of a pool.

Slope = (Depth of Deep End - Depth of Shallow End) / Length of Slope

Variables:

  • Depth of Deep End (feet)
  • Depth of Shallow End (feet)
  • Length of Slope (feet)
  • Slope (ratio) – This is the calculated slope of the pool expressed as a ratio (e.g., 1:4)

To calculate the pool slope, subtract the depth of the shallow end from the depth of the deep end and divide the result by the length of the slope. The result is the slope of the pool expressed as a ratio.

What is Pool Slope?

Pool slope refers to the incline between the shallow and deep ends of a pool. It is an important design aspect for pools as it affects safety, usability, and aesthetics. The slope is typically expressed as a ratio, indicating how much the pool depth changes over a certain distance.

How to Calculate Pool Slope?

The following steps outline how to calculate the Pool Slope.


  1. First, measure the depth of the deep end of the pool.
  2. Next, measure the depth of the shallow end of the pool.
  3. Measure the length of the slope (the distance over which the pool depth changes from the shallow end to the deep end).
  4. Use the formula to calculate the slope: Slope = (Depth of Deep End – Depth of Shallow End) / Length of Slope.
  5. Enter the measurements into the calculator above to get the slope ratio.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Depth of Deep End = 8 feet

Depth of Shallow End = 3 feet

Length of Slope = 25 feet
