Egress Stair Dimensions

Egress Stair Dimensions

Measuring egress stair steps is a relatively simple process. The most accurate way to measure is to use a measuring tape. We'll explain how in this blog.

Are you looking to find egress stair dimensions so you can apply carpet stair treads? Accurate measurement of egress stair dimensions will ensure you get the right fit of carpet stair treads for your needs.

Here are the tools needed for measuring egress stair dimensions:

  • Tape measure
  • Level
  • Pencil
  • Paper 

Here is a step-by-step guide to measuring egress stair dimensions:

  1.  First, measure the height of the step from the floor to the top of the step. Do this by placing the end of the tape measure at the floor and extending it up to the top of the step. Make a note of this measurement on the paper.
  2. Then, measure the depth of the step by placing the end of the tape measure at the back of the step and extending it to the front of the step. Again, make a note of this measurement on the paper.
  3. Finally, measure the width of the step by placing the end of the tape measure at one side of the step and extending it to the other side. Make a note of this measurement on the paper.
  4. Once all the measurements have been taken, you will have a complete picture of the dimensions of the stair step.

Common mistakes to avoid when measuring egress stair dimensions include not accounting for the thickness of the stair tread overlay and not measuring the rise and run of the stairs accurately.

Measuring curved stairs is takes a little more work, but it reletively simple as well. 

What is an Egress Staircase?

An egress staircase is a type of staircase that provides a safe means of exit from a building in case of an emergency. It is designed to meet the code requirements for exit discharge and access exit, which are essential for the safety of occupants in a building. Egress staircases are an important feature in homes as they provide a safe means of escape in case of a fire or other emergency.

Stair Tread Overlays for Increased Safety

Stair tread overlays are an excellent way to increase safety on egress stairs. 

The benefits of using stair tread overlays include:

  • increased traction
  • reduced slip and fall accidents
  • improved durability.

Types of Stair Treads Available

Stair treads come in a variety of materials, shapes, and sizes to suit any home or business.

Common materials used for stair treads include:

  • wood
  • metal
  • stone
  • vinyl.
  • Rubber

Standard Sizing for Egress Stairs

The International Building Code (IBC) provides standard sizing for egress stairs. The egress capacity factor is used to determine the minimum width of the egress stair. The factors that affect egress stair sizing include the number of occupants in a building, the type of occupancy, and the height of the building.

To determine the appropriate size for egress stairs in your home, you should consult with a professional such as Code Red Consultants. They are a nationally recognized testing laboratory that can provide guidance on the exterior stair code requirements and the International Code Council (ICC) standards.

Ensuring Safety with Egress Stairs

Common safety hazards to watch out for in egress stairs include loose or missing handrails, uneven stairs, and slippery surfaces. Here are some tips for maintaining egress stair safety:

  • Keep the stairs clear of clutter and debris.
  • Install handrails on both sides of the stairs.
  • Ensure that the stairs are well-lit.
  • Regularly inspect the stairs for any signs of damage or wear.
  • Install stair treads for added traction. 


Getting the accurate stair tread dimentions and installation of stair treads to your stairs is essential for ensuring safety. Installing stair tread overlays, and ensuring that their egress stairs meet the standard sizing requirements, will help increase overall safety. By following these guidelines, you can rest assure that those using the stairs are safe in case of an emergency.
