Every successful stair runner installation starts with the right measurements. In this video, I’ll show you the exact method I use on every project to measure staircases so your runner fits perfectly the first time.

Always measure twice before you cut — it saves material and prevents costly mistakes.

Once you’ve measured your stairs, the next step is running the numbers. This calculator uses the same formula I use on every professional install — based on 19 inches per stair (average depth). Some staircases may run deeper (up to 22 inches), so always double-check your own measurements before ordering.

Add 1–2 extra feet to your order to give yourself a safety margin — especially if your stairs vary slightly in depth.

Before you install a stair runner, you need to lay down your underpad. This adds comfort underfoot, reduces wear, and helps your runner last longer. In this video, I’ll show you exactly how to cut and staple your underpad so your stairs are fully prepped for the runner installation.

Installing the runner is where everything comes together. In this video, I’ll walk you through how to start at the base, keep your runner aligned, and staple it securely as you work your way up the staircase. By following this method, you’ll get a professional-looking finish even as a DIY installer.

Always start from the bottom step and work upward — this keeps your runner tight, aligned, and prevents shifting as you climb.

The final step is all about locking in your work so your stair runner looks sharp and stays in place for years. In this video, I’ll show you how to trim any excess, secure the top edge, and double-check your staples for a clean, professional finish.

Use a stair tool (or carpet bolster) to tuck the runner neatly into every crease. This gives your stairs a crisp, tailored look that lasts.
