Enter the length of the deck and the width of the stringer into the calculator to determine the number of stringers needed. This calculator can also evaluate any of the variables given the others are known.

## Deck Stringer Formula

The following formula is used to calculate the number of deck stringers needed.

S = (L / W) + 1

Variables:

• S is the number of stringers needed L is the length of the deck (inches) W is the width of the stringer (inches)

To calculate the number of stringers needed for a deck, divide the length of the deck by the width of a single stringer. Add 1 to the result to account for the necessary overhang on each end of the deck.

## What is a Deck Stringer?

A deck stringer is a structural component used in the construction of decks, bridges, and other structures. It is a long, horizontal piece of timber or metal that connects the deck to the main structure, providing support and stability. The stringers are typically spaced evenly across the width of the deck and serve as the base for the deck boards or planks. They play a crucial role in distributing the weight load evenly across the structure, ensuring its safety and durability.
