The key to an eye-catching outdoor living space? A polished perimeter. If you’ve chosen enduringly beautiful composite decking, opting for durable deck railing is the next logical step. We’ll cover:
- Different components of a deck railing system.
- Correct deck railing height — plus, the right width of your balusters and height from deck surface to bottom rail.
- Your deck railing options.
What Is a Deck Railing System?
When you think “deck railing,” you may think of it as a single piece tracing the outside of your deck. In reality, deck railing is a system of interconnected (and often customizable) parts.
Parts of a Deck Railing System
What Is the Right Deck Railing Height for My Deck?
In the U.S., the International Residential Code (IRC) dictates the minimum required deck railing height.
Note: Please be sure to check with all local building codes in your municipality and state before beginning any projects. Thoroughly review the relevant Railing Installation Guide before beginning.
There are a few additional minimum height and width requirements to keep in mind, especially if you’re interested in DIY-ing your railing.
Spacing Requirements for Balusters
The balusters, or upright portions between posts, should be spaced no more than 4” apart.
Note: This won’t apply for a glass panel infill, which is one solid piece of glass.
Spacing Requirements for Bottom Rail
For most states, the distance between the surface of the deck and the bottom rail (the bottommost bar, running perpendicular to the deck) should be no more than a 4” gap.
What Are My Deck Railing Options?
- Impervious to moisture damage: A composite core with a 4-sided cap covers the backside and grooves and contains no organic wood filler.
- Enduringly beautiful: Whether you go traditional or modern, your composite deck railing system won’t weather like wood railings do.
- Environmentally friendly: Composite railings from TimberTech are made from up to 50% recycled material.
- Offers an attractive wrought iron-inspired look: Powder-coated aluminum keeps the look sleek and inviting, and the timeless profile ensures clear sightlines.
- Incredible durability: Won’t rot or deteriorate and resists fading, staining, and scratching. Plus, exceptional moisture resistance protects against corrosion, fading, or warping.

Choosing Your TimberTech Deck Railing
Once you’ve decided between aluminum or composite railing, customizing the perfect complement to your deck is easy. Just follow these steps:
Step 1: Choose Your Top Rail
The top rail will either be aluminum, composite — or, in the case of Drink Rail, a moisture-resistant TimberTech composite deck board.
Step 2: Choose Your Color
Select the right hue for you. Choose from black, white, or shades of brown/bronze for a polished perimeter that will complement your outdoor living space, whatever the aesthetic.
Step 3: Choose Your Infill
Your infill is the portion that “fills” the space between the top and bottom rail. Choose from infill options including:
Go for contemporary and industrial-chic with this infill that maintains clean sightlines.
Available in both square and round varieties, this durable option can go modern or traditional.
For a classically elegant look, go for enduringly beautiful composite balusters.
