Curved Stair Dimensions

Curved Stair Dimensions

This blog post will provide a step-by-step guide on how to accurately calculate curved stair dimensions, and how to make templates for custom orders.

Are you looking to buy carpet stair treads, but unsure if you can find the right fit? Curved stairs can be particularly challenging to navigate, especially for children and elderly family members. But, there are options out there that can help. Custom carpet stair treads can provide an added layer of safety while also enhancing the design of your curved staircase. Oak Valley Designs offers a wide range of carpet stair treads, and also offers custom options. Their products are easy to install, and will elave your staircase looking a step above. 

It's very important to get the correct measurements when ordering custom carpet stair treads.

To get curved stair dimensions:

  1. Measure the tread depth - This is the horizontal distance between the front edge and the back edge of the tread.

  2. Measure the tread width - This is the horizontal distance between the two side edges of the tread.

  3. Measure the riser height - This is the vertical distance between the top of one tread and the top of the next tread.

  4. Measure the angle of the curve - This is the angle of the curve of your curved staircase. You can use a protractor or angle finder to measure this.

Measuring Your Curved Stair Steps Properly

Before ordering custom carpet stair treads, it's essential to measure your curved stair steps properly. This will ensure that you order the correct size treads that fit your stairs perfectly. Here are the tools you'll need for measuring:

Tools You'll Need for Measuring

  • Tape measure
  • Pen and paper
  • Straight edge

How to Measure Curved Stairs without a Protractor 

Measuring curved stairs without a protractor can be done using a few simple tools. First, you will need a tape measure and a level. Start by measuring the rise and run of each step, which is the distance from the top of one step to the top of the next. Then, use the level to measure the angle of each step. Place the level on the edge of the step and adjust it until the bubble is in the center. Finally, measure the angle with the tape measure. Make sure to measure from the same point on each step, such as the back corner, to ensure accuracy.

Ordering the Correct Size Treads

When ordering custom carpet stair treads, you'll need to decide between standard tread sizes and custom tread sizes. Here are the benefits of each:

Standard Tread Sizes vs. Custom Tread Sizes

  •  Benefits of custom treads: Custom treads are made to fit your specific curved staircase, ensuring a perfect fit. They also provide more design options, including different materials, colors, and patterns.

  • Standard tread sizes available: If you have a standard curved staircase, you may be able to find pre-made treads that fit your stairs. However, these may not fit perfectly, and you may have limited design options.

How to Make a Template for Custom Orders

If you decide to order custom carpet stair treads, you may need to make a template of your curved stair steps. Here's how:

Materials needed

  • Large piece of paper or cardboard
  • Scissors
  • Tape
  • Pen or marker

Step-by-step instructions

  1. Cut the paper or cardboard to the same size as your curved stair step.

  2. Place the paper or cardboard on the stair step and tape it down.

  3. Trace the outline of the stair step onto the paper or cardboard.

  4. Cut out the traced shape.

  5. Label the template with the corresponding stair step number.

  6. Repeat for each curved stair step.

  7. Take a photo of each template and send them to the custom carpet stair tread manufacturer.

Measuring Egress Stair Dimentions 

Measuring egress stair dimensions is relatively easy and can be done with simple tools. To start, you'll need a tape measure, a level, and a calculator.

  1. Begin by measuring the total rise of the stair, which is the vertical distance from the top of the stair to the bottom.
  2. Then, measure the total run, which is the horizontal distance between the two points.
  3. Next, divide the total rise by the total run to calculate the stair's slope.
  4. Finally, measure the individual stair treads and risers to get their exact dimensions. This will help you determine the exact size of the stairs and ensure that they meet the necessary safety requirements.

Measuring Stair Landings

If your curved staircase has landings, you'll also need to measure those for custom carpet stair treads. Here's how:

How to Measure Stair Landings

  1. Measure the length and width - This is the horizontal and vertical distance of the landing.

  2. Measure the angle of the curve - This is the angle of the curve of your landing. You can use a protractor or angle finder to measure this.

Ordering Custom Carpet Stair Treads for Stair Landings

Custom carpet stair treads for landings provide added safety and design options. When ordering, be sure to specify that the treads are for a landing and provide the measurements you took.


Custom carpet stair treads are an excellent option for those looking to add style and safety to their curved staircase. By measuring your curved stair steps and landings correctly, you can order the correct size treads that fit your stairs perfectly.
