Deck Slope Calculator

Formula

To calculate the deck slope:

$\text{DS} = \text{DL} \times 0.25$

Where:

$\text{DS}$ is the Deck Slope (inches of slope height/drop)
$\text{DL}$ is the total length of the deck (feet)

What is Deck Slope?

The deck slope is the height or drop in inches over the length of the deck. This calculation helps determine the proper slope for drainage and stability of the deck structure.

Example Calculation 1

Let's assume the following value:

Deck Length ( $\text{DL}$ ) = 20 feet

Using the formula:

$\text{DS} = 20 \times 0.25 = 5 \, \text{inches}$

The Deck Slope is 5 inches.

Example Calculation 2

Let's assume the following value:

Deck Length ( $\text{DL}$ ) = 35 feet

Using the formula:

$\text{DS} = 35 \times 0.25 = 8.75 \, \text{inches}$

The Deck Slope is 8.75 inches.
