How many metres of stair runner do I need?

For a typical UK or European staircase, allow roughly 0.4 to 0.45 m of runner per step. A 13 step flight lands at about 5.4 m before waste.

Optional starting measurements

Example measurements only, not building-code advice. Replace them with measurements from your own stairs.

Check a few steps before using one set of measurements for the whole flight.

Count the tread-and-riser pairs the runner will cover. Exclude landings.

Measure the runner path across the flat tread. Fractions like 10 1/2 work.

The vertical face between two treads.

%

10% is the starting allowance here, not a guarantee. Ask your fitter about patterns and turns.

Enter the extra runner path around the edge, including any underside wrap. Do not add it twice if it is already included in your measurements.

Side elevation of a staircase. The runner travels across each tread and down each riser, so every step consumes tread depth plus riser height of material.

Metres by step count

At 41.5 cm per step: 10 steps = 4.15 m, 13 steps = 5.4 m, 15 steps = 6.23 m, 16 steps = 6.64 m. Add 10% and round up to the nearest 10 cm.

Roll lengths in metres

Ask for the longest continuous cut available for your chosen runner. Enter that value in the seam planner for a preliminary piece count; have the installer confirm the actual join positions.

Don't forget the landing

A half landing adds 0.9 to 1.5 m in one go, which is often the difference between one piece and two.
