Deck boards come in a variety of sizes and thicknesses, and understanding the differences between them can help you make an informed decision. In this post, we’ll take a closer look at 5/4 deck boards and how they compare to other options.

Standard Deck Board Sizes

Deck boards are typically sold in standard sizes, with the most common being 2×6, 5/4×6, and 2×4. The first number in the size refers to the thickness, while the second number refers to the width. So, a 2×6 board is 1.5 inches thick and 5.5 inches wide.

5/4 Boards Versus Other Options

5/4 deck boards are a popular choice for many homeowners because they are thicker than standard 2×6 boards, making them more durable and able to support heavier loads. 5/4 boards are also available in a variety of widths, including 4”, 6”, 8”, and 10”.

Compared to 2×4 boards, which are only 1.5 inches thick, 5/4 boards are more durable and better able to withstand heavy foot traffic and furniture. However, they are also more expensive than 2×4 boards.

When compared to 2×6 boards, 5/4 boards are slightly thinner (1.25 inches versus 1.5 inches). However, because 5/4 boards are made from thicker material, they are still stronger and more durable than 2×6 boards.

Choosing the right board thickness for your deck can be a challenge, but understanding the differences between standard sizes and materials can help you make an informed decision. Whether you choose 5/4 boards or another option, make sure to select a board thickness that will provide the strength and durability you need for your deck.
