Enter the total length of the deck (ft) into the Deck Slope Calculator. The calculator will evaluate and display the Deck Slope.

## Deck Slope Formula

The following formula is used to calculate the Deck Slope.

**DS = DL * .25**

- Where DS is the Deck Slope (inches of slope height/drop)
- DL is the total length of the deck (ft)

## How to Calculate Deck Slope?

The following example problems outline how to calculate Deck Slope.

Example Problem #1:

- First, determine the total length of the deck (ft).
- The total length of the deck (ft) is given as: 51.

- Finally, calculate the Deck Slope using the equation above:

DS = DL * .25

The values given above are inserted into the equation below and the solution is calculated:

DS = 51 * .25 = 12.75 (inches of slope height/drop)

Example Problem #2:** **

For this problem, the variables needed are provided below:

total length of the deck (ft) = 30

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

DS = DL * .25** = ?**
