Designing a curved staircase sounds tricky, but it doesn’t have to be. A stylish deck deserves stairs that feel just as inviting. Designing circular stairs for decks means planning and building a curved set of steps that connect your deck to the ground in a safe, beautiful way.
These stairs create a smooth flow and add instant curb appeal without taking up too much space. By learning the basics, you can design and build them yourself or feel confident working with a contractor. This guide will show you how to pick the right style, plan your layout, and even add carpet stair treads for extra comfort and safety.
What Are Circular Deck Stairs?
Circular stairs are a curved set of steps that connect your deck to the ground or patio.
Unlike straight stairs, they sweep out in a graceful curve. Many homeowners choose them for these reasons:
-
They look luxurious and unique.
-
They make good use of tight spaces.
-
They offer smoother movement around the deck.
-
They create a striking first impression.
While circular stairs often cost more than straight stairs, the boost in style and ease of use may be worth it.
Types of Stairs to Consider
When planning your project, you’ll come across a few types of stairs.
Here are the most common options:
1. Straight Stairs
These are the simplest and most affordable style. They run in a straight line from the deck to the ground.
2. L-Shaped or U-Shaped Stairs
These stairs change direction at a landing. They fit well in small yards and can look formal.
3. Spiral Stairs
Spiral stairs twist around a central pole. They save the most space but can feel tight if you carry big items.
4. Circular Stairs
These curve gently without wrapping fully around a post. They are broader and more open than spiral stairs, blending beauty and function.
Tip: When comparing types of stairs, think about who will use them. Kids and pets often find wider curved stairs easier to climb.
How to Build Circular Stairs
How to build circular stairs may sound daunting, but it starts with a few clear steps:
1. Plan Your Design
Sketch out your stairs. Decide on the radius (the distance from the center of the curve to the edge) and the rise and run of each step.
For safety and comfort:
-
Keep the rise (height of each step) between 6–7 inches.
-
Make the tread (depth) at least 10 inches deep.
-
Plan a width of at least 36 inches so people don’t feel cramped.
2. Choose Materials
Use treated lumber or composite boards rated for outdoor use. If you’re adding stair treads, look for weather-resistant styles that add grip and comfort.
3. Lay Out the Curve
Mark the arc on the ground using a stake and string to guide your cut lines.
4. Build the Stringers
Stringers are the backbone of your stairs. For circular stairs, you may need to cut curved stringers from sturdy plywood or laminated boards.
This is the trickiest part. Take your time measuring and marking.
5. Install Treads and Risers
Secure each step firmly. Use outdoor-rated screws and check for wobble before moving on.
6. Add Railings
Railings keep everyone safe, especially kids and guests. Choose a style that complements your deck’s design.
Pro Tip: Always check your local building codes before you begin. Some areas have rules about railing height and stair dimensions.
Design Ideas for a Stunning Look
Here are a few ideas to make your stairs feel special:
-
Mix Materials: Combine wood steps with metal railings for contrast.
-
Add Lighting: Place LED lights under each tread for a soft glow at night.
-
Use Neutral Colors: Soft browns and grays feel timeless and hide dirt.
-
Install Quality Stair Treads: Oak Valley Designs offers easy-to-install treads that add comfort and style to every step.
