Deck Post Spacing Calculator

Formula

The formula to calculate the deck post spacing is:

$\text{DPS} = \frac{\text{L} - \text{W}}{\text{N} + 1}$

Where:

$\text{DPS}$ is the deck post spacing
$\text{L}$ is the length of the deck
$\text{W}$ is the width of the deck
$\text{N}$ is the total number of deck posts

What is Deck Post Spacing?

Deck post spacing refers to the distance between the posts that support a deck. This is a crucial aspect of deck construction as it directly impacts the stability and safety of the deck.

Example Calculation

Example:

Length: 20 feet
Width: 10 feet
Total Number of Deck Posts: 4

Calculation:

$\text{DPS} = \frac{20 - 10}{4 + 1} = 2 \text{ feet}$
