Tread Overhang on Stairs

Tread Overhang on Stairs

Learn how tread overhang on stairs can add style and safety, and explore options like carpet landings and bullnose designs.

Tread overhang on stairs refers to the part of each step that extends slightly past the riser below it.

This thoughtful design detail isn’t just about looks; it’s an important way to make stairs safer and more comfortable.

Whether you’re adding carpet stair landings to make stairs cozier or choosing wood treads for a sleek look, getting the right overhang matters.

What Is the Ideal Tread Overhang for Stair Safety?  

For safe, comfortable steps, the ideal tread overhang ranges between 3/4" and 1-1/4".

This small extension gives just enough space for each foot to land securely on the stair without risk of tripping.

If the overhang is too small, steps may feel steep and awkward.

Too large, and it can increase the chance of stumbles, especially on descent.

A well-chosen overhang, within the standard range, keeps staircases safe and comfortable for all ages.

Why Is There a Code Requirement for Tread Overhang?  

The building codes in the U.S. recommend specific ranges for tread overhangs to make sure staircases are safe and accessible.

According to these codes, most stair treads less than 11 inches deep need an overhang of at least 3/4" and no more than 1-1/4".

This range keeps the slope comfortable and provides enough room for secure foot placement.

Following these codes also makes it easier for families, guests, and others to navigate stairs safely.

How Does Tread Overhang Impact Carpeted Stairs?  

Adding carpet to stairs, especially on stair landings, adds warmth and luxury to any home.

When stairs are carpeted, a tread overhang is especially useful because it allows the carpet to wrap neatly over the step’s edge.

A rounded tread, known as a stair tread bullnose overhang, is often the best choice for carpeted stairs.

The rounded edge of a bullnose overhang protects toes, reduces wear on the carpet, and creates a polished, inviting look for each step.

What is a Stair Tread Bullnose Overhang?  

A stair tread bullnose overhang is a rounded edge that curves down over each step, adding both comfort and style.

This type of overhang is perfect for those who prefer a softer look or who are adding carpet to their stairs.

Not only does the bullnose add a finished touch, but it also visually highlights each step, helping with safe navigation.

For homes with accent lighting or carpet stair landings, a bullnose overhang is a classic choice that adds subtle elegance.

Steps to Success  

Choosing the right tread overhang can add a touch of luxury and safety to any staircase.

A comfortable overhang, between 3/4" and 1-1/4", provides secure footing and enhances the appearance of each step.

If you love the idea of carpet stair landings, a bullnose overhang can offer the perfect blend of softness, safety, and style.

With a well-chosen tread overhang, your stairs can be both beautiful and functional for years to come.
