Top Tips for Measuring Stairs for Carpet Runners

Adding a carpet runner to your stairs can enhance your home’s aesthetic while improving safety and comfort. But before you can choose the perfect runner, it’s essential to get accurate measurements. Properly measuring stairs for a carpet runner ensures a precise fit, prevents material waste, and simplifies the installation process. Here’s a step-by-step guide on how to measure stairs for a carpet runner, with some practical tips to make sure you get it right.

1. Gather Your Tools and Prepare

Before you start measuring, gather the essential tools: a tape measure, a notepad, and a pencil. For some measurements, especially with long staircases, it’s helpful to have an extra set of hands to hold the tape measure or double-check dimensions.

Key Tools Needed: Tape measure (preferably retractable), notepad, pencil, calculator (optional), and an assistant if possible.

2. Measure Each Stair Tread and Riser
For a carpet runner to fit your stairs perfectly, you need to measure both the tread and the riser.

Tread Measurement: The tread is the flat part of each step where your foot lands. Measure the depth of the tread from the front (the edge or “nose” of the step) to where it meets the riser. Record this measurement accurately for each step.

Riser Measurement: The riser is the vertical section between each tread. Measure the height of the riser from the bottom of one tread to the bottom of the next tread above it.

Tip: Although stairs in most homes are uniform, slight variations can occur, especially in older homes. Measure each step individually and note any differences.

3. Calculate the Width of the Runner

Once you know the dimensions of each step, decide how wide you want the carpet runner to be. Typical carpet runners leave 10 centimetres of the stair exposed on each side, but this can vary based on your preference and the width of your stairs.

How to Measure: Measure the full width of the stairs, then subtract the amount of wood you want to leave exposed on each side. For example, if your staircase is 80 centre mitres wide and you want to leave 10 centimetres on each side, your runner width would be 60 centimetres.

Tip: Measure both the top and bottom of the staircase, as some staircases slightly vary in width from top to bottom. Use the narrowest width as your runner measurement to ensure it fits throughout.

4. Measure Total Staircase Length
Now, calculate the total length of the runner by measuring the entire staircase from top to bottom.

How to Measure the Staircase Length: Begin at the top of the stairs and measure down each tread and riser, adding up the total measurement. To be thorough, measure as follows:

For Each Step: Add the tread depth and the riser height together to get the total length for each step.

Multiply by the Number of Steps: Once you have the measurement for one complete step (tread plus riser), multiply it by the number of steps in the staircase. For instance, if each step is 50 centimetres inches and you have 12 steps, the total length would be 50 centimetres x 12 = 600 centimetres (6 metres).

Add Landing Lengths: If your staircase includes any landings, measure their depth separately and add them to your total length.

Tip: Measure twice to confirm accuracy, especially if your staircase includes winders (angled or curved steps) or landings.

5. Adjust for Landings, Winders, and Curved Stairs

If your staircase includes landings, curved stairs, or winders (steps that turn or are pie-shaped), additional measurements are needed to ensure proper fit.

Landings: Measure the length and width of each landing separately, ensuring you account for the runner width you chose. Some runners may need custom pieces to fit landings, particularly if the landing is wider than the stairs.

Winders and Curved Stairs: If you have winders, measure both the narrow and wide ends of each step to get the exact dimensions. For curved stairs, use a flexible measuring tape to follow the curve of the tread and riser.

Tip: For complex staircases, consider consulting a professional installer, as they can ensure accurate measurements and help determine if custom adjustments are necessary.

6. Double-Check Your Measurements

Before ordering your carpet runner, go over each measurement and check for consistency. Ensure your final measurements include all treads, risers, and any additional sections like landings.

Why Double-Check? Miscalculations can lead to ordering too little or too much carpet, affecting both your budget and installation ease. Double-checking prevents costly mistakes and ensures a seamless fit.

Tip: It’s a good idea to measure each section twice, and if possible, have a friend or family member verify your measurements.

7. Consult with a Carpet Specialist if Needed

If you’re unsure about your measurements or have a unique staircase layout, consulting with a carpet professional can be very helpful. Many carpet stores offer assistance in calculating measurements and can provide recommendations on custom fitting options for stair runners with landings, curves, or other unique features.

Summary

Knowing how to measure stairs for a carpet runner is essential to ensure a precise fit, a smooth installation process, and a stylish result. With accurate measurements for each tread, riser, and any additional sections like landings, you’ll be well-prepared to order the perfect runner for your staircase. By following these tips and double-checking your measurements, you can bring comfort, safety, and style to your stairs without any surprises on installation day.
