To help you in your journey, we’ve gathered deck top rail ideas to suit your unique style, plus guidance on how to incorporate each look into your design.
FAQ: “What Is the Top Rail on a Deck Called?”
Before you jump into deck top rail ideas, get familiar with all the components of a railing, including the top rail, so you can customize your design like a pro.
- Top rail – The uppermost piece of the railing that runs between posts and connects to the top of the infill. The top rail is also sometimes referred to as a cap rail. A top rail is different from a handrail, which is typically installed lower than the top rail and is meant to be graspable.
- Bottom rail – The lower piece of the railing that runs parallel to the top rail between posts and connects to the bottom of the infill.
- Infill – The piece that fits between the top and bottom rail, filling the inner portion of the rail.
- Post – The vertical piece that connects each railing panel and secures the railing to the deck surface. Composite railings feature a post sleeve that covers a wood post, while aluminum railings feature a full aluminum post.
- Post cap – The top piece of the post that often features a design and can include lighting.
- Post skirt – A detail piece that covers the bottom of the post, where it connects to the deck surface.
Deck Top Rail Ideas: Know Your Material Options
Deck top rail ideas and styles can vary by your material choice. While traditional wood has historically been a popular choice, it’s not the best. More contemporary materials like composite and aluminum railing can give you that look you want — with the durability and performance you deserve.
Deck Railing Materials
Made of a mix of high-performance polymers and recycled wood and plastic fibers, composite railing is designed to look like real wood while being far more durable. Choose top rail designs ranging from traditional milled wood looks to more contemporary, minimalist designs.
Aluminum railing is designed to mimic the look of wrought iron, with far greater resistance to rust, corrosion, and fading. Choose from classically inspired top rails to more sleek, modern designs.
With TimberTech® composite and aluminum railing, you skip the rigorous maintenance while enjoying high-performance, high-style railing designs. Plus, our railing systems offer several top rail, color, and infill options, so you’re bound to find the right look for your space.
Now that you’re familiar with your material choices, explore deck top rail ideas from contemporary, popular options to more timeless, traditional designs.

Railing Installation Best Practices
No matter what style of railing you choose, there are common railing installation best practices you’ll need to abide by to ensure a safe, sturdy structure. If you’re thinking of installing your railing on only a section of your deck, keep in mind for your design that any part of your deck surface that is 30” or more above the ground will require a railing.
Common Railing Best Practices
Deck height: 30” or more above the ground will require a railing
Top rail height: At least 36” minimum from the deck floor.
Space between balusters: 4” maximum.
Space between bottom rail and deck floor: 4” maximum.
