Getting Your Stair Dimensions

Upgrading your staircase?

Before you pick patterns or colors, getting your stair dimensions right is the first and most important step.

Accurate measurements ensure your carpet stair treads fit securely, look polished, and perform safely.

In this guide, you'll learn how to measure straight and curved stairs, avoid common mistakes, and choose the right tread size for your space.

By the end, you'll be ready to order with confidence—and install with ease.

Why Stair Measurements Matter  

Choosing the wrong size tread can leave you with uneven edges, tripping hazards, or worse—a product that doesn’t even fit.

If you’re a DIYer, there’s nothing more frustrating than investing time and money into a home project only to realize your measurements were off.

And for families with little feet or four-legged friends running around, stair safety isn't optional—it's a priority.

Getting your stair dimensions right isn't just about making sure things fit; it's about creating a home that feels secure, looks beautiful, and stands the test of time.

What You’ll Need to Measure Stairs  

Taking measurements doesn’t require anything fancy.

Most people already have everything they need in a kitchen drawer or toolbox.

Here’s what to grab before you begin:

• A tape measure (preferably a flexible one for tight spaces)

• A pencil or pen

• A sheet of paper or notepad

• Optional: a flashlight for low-light stairwells

If you’re working with curved stairs, it may also help to have a helper on hand or a flexible fabric measuring tape to capture more complex angles.

Step 1: Measuring the Width  

The width is the distance from one side of the stair to the other, running horizontally across the step.

Here’s how to do it right:

• Measure from the left edge to the right edge of the stair step.

• If your stairs have any variation in shape (especially near a curve or post), measure every step individually.

• Write down the smallest width—that’s your base measurement.

For most Oak Valley customers, the visual appeal of 2–3 inches of exposed wood on each side of the tread is ideal.

This spacing frames the stair tread nicely and maintains that high-end look.

Step 2: Measuring the Depth  

The depth refers to the front-to-back dimension of the stair tread, also known as the "run."

To measure it:

• Place your tape at the very front edge of the step.

• Extend it to the back where the stair meets the riser or wall.

• Note the measurement at the deepest point—this ensures full coverage and avoids slippage.

Getting your stair dimensions for depth is especially important if your stairs have a noticeable overhang or if you're installing thicker treads that might push beyond the edge.

Step 3: Measuring the Height (If Needed)  

While height isn’t always needed for carpet stair treads, it becomes relevant for homeowners who are doing a complete staircase makeover or dealing with unusual layouts.

To find the height (or rise):

• Measure from the top of one stair to the top of the next.

• This gives you the vertical distance between each step.

If you’re working on a new construction project, this information is often used alongside building codes to ensure compliance and safety.

How to Tackle Curved Staircases  

Getting your stair dimensions right becomes even more important when your staircase isn’t perfectly straight.

For curved or spiral staircases, dimensions can shift slightly step by step.

Here’s how to measure curved stair dimensions the right way:

1. Start with the total rise: Measure from the bottom landing to the top of the last stair.

2. Count the number of steps to divide and calculate the average rise per step.

3. Measure the total horizontal run, or how far the staircase extends horizontally.

4. Divide by the number of steps to get the average run per stair.

When dealing with curved stair dimensions, always take multiple measurements on each individual step.

For example, measure both the narrow side and the wide side of the same step.

Then average those two numbers to get your final dimension.

These variations might seem small, but they matter—especially for a snug tread fit that won’t shift or wrinkle over time.

Understanding Stair Treads and Their Purpose  

Stair treads are the horizontal boards you walk on as you go up and down your staircase.

While bare wood treads can be attractive, they also come with risks—like slipping, scuffing, and damage over time.

That’s why many homeowners choose carpet stair treads as a solution.

They add comfort, grip, and design flexibility—all without the cost or permanence of a traditional stair runner.

What Makes Carpet Stair Treads a Smart Choice?  

Adding stair treads is one of the simplest and most cost-effective ways to upgrade your home.

Here’s why more families are choosing carpet stair treads every day:

• Non-slip protection: Treads reduce the risk of slipping, especially on slick hardwood or laminate stairs.

• Added comfort: Padded material softens every step—ideal for pets, toddlers, or aging knees.

• Noise reduction: No more creaky steps or echoing footsteps. Your house stays quieter, especially during naptime.

• DIY-friendly install: No tools or glue required. Simply peel and stick using OVD’s environmentally friendly adhesive.

• Style upgrade: Available in dozens of textures, patterns, and neutrals to match any home décor.

You don’t need to be an interior designer or contractor to pull off a polished, elevated stairwell—just a measuring tape and some confidence.

How to Choose the Right Size Based on Your Measurements  

Once you’ve finished getting your stair dimensions, you can confidently shop for the right size.

Here’s how to make sure the treads you choose are the perfect fit for your stairs—and your lifestyle:

• Follow your measurements: Always buy based on the smallest width and depth you recorded.

• Leave breathing room: If you love the look of exposed wood, choose treads that are 2–3 inches narrower than your total stair width.

• Consider your home’s style: Modern homes tend to favor sleeker, narrower treads, while traditional homes often look best with wider, fuller coverage.

• Think about your household: If you have children, elderly parents, or pets, wider treads often feel more secure and forgiving.

Need a custom size?

Oak Valley Designs offers made-to-order treads so you can match your staircase exactly—even those tricky curved stair dimensions.

Why Getting It Right From the Start Matters  

Incorrect measurements lead to more than just an ill-fitting product.

They can result in returns, delays, added costs, and a lot of DIY frustration.

Taking the time to get your stair dimensions the right way helps ensure:

• A seamless, fast installation

• Minimal adjustment or trimming

• Long-lasting results that stay in place

• That satisfying “I did it myself” feeling

And with OVD’s $1 swatch program, you can even test out color, texture, and thickness before you commit to a full order.

What If You Have Unique Stair Features?  

Some staircases include landings, transitions, or even partial turns that break up the traditional stair flow.

If this is your case, here’s what you can do:

• Measure each section individually: Landings, winder steps, and corners may need a different tread size or layout.

• Take photos: When in doubt, send us pictures of your stair layout. We’ll help you decide what you need.

• Go custom: Oak Valley’s custom order program allows for truly one-of-a-kind sizing for complex stair layouts.

Even if your home features detailed trim or uneven curved stair dimensions, we can help you create a solution that blends comfort and craftsmanship.
