Laying Decking Boards: The Direction Matters
When it comes to installing a wooden deck, one of the most fundamental questions that homeowners and DIY enthusiasts often ask is: "What direction do you lay decking boards?" The direction you choose to lay your decking boards can significantly impact the aesthetics, functionality, and longevity of your deck. Let's delve into the intricacies of this decision, ensuring you make an informed choice that enhances your outdoor space.
Understanding Decking Board Direction
Decking boards can be laid in two primary directions: parallel to the house (with the groove side facing the house) or perpendicular to the house. Each direction has its own advantages and considerations, which we will explore in detail.
Parallel to the House
- Pros:
- Allows for easier water runoff, preventing puddles and potential damage to the deck.
- Creates a more uniform and continuous appearance, as the boards align with the house's lines.
- Can make the deck appear longer and more spacious.
- Cons:
- Can make the deck appear narrower, as the boards' width is emphasized.
- Requires more precise cutting and fitting around the perimeter of the deck.
Perpendicular to the House
- Pros:
- Draws the eye inwards, making the deck feel more intimate and cozy.
- Can make the deck appear wider, as the boards' length is emphasized.
- Allows for easier installation around obstacles, such as stairs or built-in features.
- Cons:
- Can lead to water pooling on the deck's surface, potentially causing damage or creating a slippery surface.
- Requires more boards to be cut to fit around the perimeter of the deck.
Considerations Beyond Direction
While the direction of your decking boards is crucial, it's not the only factor to consider. The type of wood, the size and spacing of the boards, and the overall design of your deck can all impact the final result. For instance, wider boards can create a more luxurious feel, while narrower boards may be more suitable for smaller decks or intricate designs.

Additionally, consider the grain pattern of the wood. Laying the boards with the grain running the same direction as the house can create a cohesive, streamlined look. Conversely, laying the boards perpendicular to the house can create a striking contrast and draw attention to the deck itself.
Best Practices for Laying Decking Boards
Regardless of the direction you choose, there are several best practices to follow when laying decking boards:
| Best Practice | Why It's Important |
|---|---|
| Start from the house and work outwards | This ensures a straight, even edge along the house and makes it easier to cut and fit boards around any obstacles. |
| Use spacers between boards | Spacers allow for proper air circulation and water drainage, preventing the growth of mold and mildew. |
| Stagger the joints between boards | Staggering joints helps to distribute weight evenly and prevents the deck from sagging or warping over time. |
| Secure boards with hidden fasteners | Hidden fasteners provide a cleaner, more attractive finish and help to prevent water from becoming trapped between the boards. |
By following these best practices, you can ensure that your deck not only looks great but also stands the test of time.

Final Thoughts
Choosing the direction to lay your decking boards is a decision that requires careful consideration. Both parallel and perpendicular layouts have their own advantages and considerations, and the best choice ultimately depends on your personal preferences and the specific requirements of your deck. By understanding the pros and cons of each direction and following best practices for installation, you can create a deck that is both functional and aesthetically pleasing.
