Difference between Stair Treads and Carpet Stair Treads

Stair treads are the horizontal pieces of wood or other materials that make up each step of a staircase. They are designed to provide a safe and stable surface for people to walk on.

Carpet stair treads are individual pieces of carpet that are designed to adhere to your stair steps, and provide comfort, style, and noise reduction. 

Difference between Stair Treads and Stair Runners

Stair runners are long pieces of carpet or other material that run down the center of a staircase. 

Stair treads cover only the top of each step 

Do I Need to Measure the Hight of my Stair Steps? 

Unlike the width and depth measurements, the height of each step is not necessary when it comes to installing carpet stair treads. This is because the treads are designed to fit snugly on top of the steps, and do not have carpet on the back of each step, as is the case with stair runners. 

Standard stair tread dimensions

The typical standard dimensions for stair treads are a minimum tread depth of 10 inches and a maximum riser height of 7 3/4 inches. The standard width of staircases in homes typically ranges from 36 to 42 inches. The width of a staircase is determined by the space available in the home, the number of risers, and the type of staircase. Generally, wider staircases are more comfortable to use and offer more stability. However, narrow staircases can also be used safely if they are designed and constructed correctly.

Importance of accurate measurements

Accurate measurements are crucial when it comes to installing carpet stair treads. If the measurements are off, the treads may not fit properly, which can lead to safety issues and an unattractive appearance. This can be especially important when measuring egress stairs. It's important to take your time and measure each step carefully.

Tips for accurate measurements

  • Take your time and measure each step carefully.
  • Measure each step twice to ensure accuracy.
  • Use a level to ensure that each step is level before measuring.
