Diagonal Decking vs. Horizontal Decking: Which Style Should You Choose?
When it comes to deck building, deciding between diagonal decking and horizontal decking can be a big choice. Each style has its own look, feel, and functionality. Whether you want to make a statement or keep things simple, here’s a guide to help you choose the best style for your deck project.
We’ll go over the pros and cons of each, how they affect things like deck frame and joist spacing, and which patterns work best for your outdoor space.
Horizontal Decking: The Classic Layout
Horizontal decking is the go-to layout for many homeowners. In this setup, deck boards are installed horizontally across the deck frame, usually running parallel to the house. It’s a straightforward approach that works with almost any type of decking material, from wood to composite.
Pros of Horizontal Decking
- Simple to Install: Because it’s a common layout, most deck builders know how to install horizontal decking quickly and easily.
- Cost-Effective: Fewer cuts and adjustments make it a budget-friendly option for many.
- Minimal Waste: With fewer cuts, there’s typically less leftover decking material.
Cons of Horizontal Decking
- Visible Butt Joints: Since the boards run horizontally, you’ll see more butt joints, which are the spots where boards meet end-to-end. These joints can expand over time if the wood expands and contracts.
- Less Sturdy for Large Decks: In larger decks, horizontal decking can feel less rigid, which might mean extra support is needed for stability.
- Simple Look: Horizontal decking provides a classic, understated look but might not be as eye-catching as other layouts.
Best For
Horizontal decking works well for smaller decks or areas where you want a simple, traditional look. If you’re working with a tighter budget or prefer a straightforward style, this layout is a good choice.
Diagonal Decking: A Stylish Twist
Diagonal decking involves placing decking boards at a 45-degree angle to the frame. This creates a dynamic look that can make your deck stand out and look more modern. Diagonal decking adds a visual boost and, in some cases, can make the deck feel sturdier.
Pros of Diagonal Decking
- Enhanced Stability: Installing deck boards diagonally can strengthen the deck frame, especially on larger decks. Diagonal lines create a more solid structure.
- Unique Look: Diagonal decking has a distinct appearance that adds interest and makes the deck feel custom.
- Better Drainage: The angle can help water run off more effectively, which helps keep the deck boards in better shape over time.
Cons of Diagonal Decking
- Higher Cost: The diagonal layout typically requires more decking material, which can increase costs.
- More Labor: Diagonal decking requires more cuts, measuring, and precision, which can make the installation process take longer.
- Wasted Material: Because of all the cuts, there may be more leftover pieces than with horizontal decking.
Best For
Diagonal decking is ideal for those who want a visually appealing deck that stands out and feels sturdy. It’s great for larger decks where extra stability is a plus and in outdoor spaces where aesthetics are a top priority.
Comparing Durability and Strength
- Horizontal Decking: This layout relies heavily on the strength of the deck frame and may need more joists for stability in larger decks. If installed properly, horizontal decking holds up well, though it’s more suited for smaller decks where stability isn’t a huge concern.
- Diagonal Decking: Thanks to the angled layout, diagonal decking often feels more solid, especially on bigger decks. The structure has extra support because of the crisscrossed deck joists and extra framing involved, making it a durable choice for larger projects.
Choosing Patterns: Adding a Custom Touch
Both horizontal and diagonal decking allow you to play with decking patterns for a unique look. You could add features like a decking inlay or try different patterns, such as a herringbone pattern or curved inlays for a bit more flair.
- Horizontal Decking Patterns: If you like the classic look but want to spice it up, consider adding a border around the deck. You can also mix and match board colors for a modern twist.
- Diagonal Decking Patterns: Diagonal decking already makes a statement, but you can take it further with patterns like chevron or herringbone. These styles are bold and make your outdoor space look polished and modern.
Considering Material Needs and Costs
The amount of decking material you’ll need depends on the pattern and layout you choose.
- Horizontal Decking: Requires less material, especially for smaller decks, which can save on costs.
- Diagonal Decking: Usually needs more decking material because of the angled cuts. This can make it pricier, but it may be worth it for the added stability and visual appeal.
If you’re set on diagonal decking but worried about costs, talk to your contractor about mixing and matching materials or minimizing waste.
Joist Spacing and Frame Requirements
- Horizontal Decking: Typically requires joist spacing of around 16 inches for a sturdy frame. In some cases, joist spacing might need to be closer for extra stability, especially on larger decks.
- Diagonal Decking: Due to the added weight and angle, diagonal decking may need closer joist spacing, often around 12 inches, to keep everything solid.
This difference in joist spacing means that diagonal decking can increase framing costs. However, this extra support also adds to the durability and lifespan of your deck.
Maintenance and Wear
Maintenance for both horizontal and diagonal decking comes down to the type of material you choose and the climate you live in.
- Horizontal Decking: Horizontal boards tend to show wear patterns along the grain, especially in high-traffic areas. This style can trap water more easily, so sealing and routine maintenance are essential.
- Diagonal Decking: The angle of diagonal decking helps with water drainage, which can help the wood last longer and reduce the chances of peeling paint or weather-related issues. Still, it will need regular maintenance to keep it in top shape.
