How much runner do 10 steps need?

For 10 covered steps, the answer still depends on your tread depth and riser height. The figures below use equal steps with no landing or nosing allowance.

With a 10 in tread and a 7.5 in riser, 10 steps need 175 in — 14 ft 7 in, or 4.44 m — before any allowance.

Your staircase

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.

Number of stairs

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

Tread depth (in)

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

Riser height (in)

The vertical face between two treads.

Waste allowance

Custom%

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

Add a nosing / overhang allowance per step

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.

This calculator provides an estimate based on the measurements and installation assumptions you enter. Complex, curved or winder staircases may require professional measurement.

One step, shown in profile

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.

The 10 step numbers at a glance

Bare length 175 in (14 ft 7 in). With 5% waste: 183.8 in (15 ft 3.8 in). With 10% waste: 192.5 in (16 ft 0.5 in). With a 36 in landing and 10% waste: 232.1 in (19 ft 4.1 in).

Metric equivalent

A 10 step flight with a 22.5 cm going and a 19 cm rise needs 4.15 m bare, about 4.57 m with 10% waste.

Where this step count shows up

10 steps is common on short flights, split-level homes and the lower half of a stair that turns at a landing.

Check before you order

Count the tread-and-riser sections the runner will actually cover, not the number someone quotes for the stair. If one step differs, switch on “Measure each step” in the calculator and enter it separately. Bullnose or curtail bottom steps need extra material your fitter should confirm.

Questions people ask

How much runner do I need for 10 stairs?: With 10 in treads and 7.5 in risers, 10 equal covered steps need 175 in (4.44 m). Adding 10% gives 192.5 in (4.89 m), before supplier rounding and with no landing or nosing allowance.
Does 10 steps mean 10 risers?: Not always. Check how many tread-and-riser sections are covered and whether the runner starts or stops partway through one. Allow for those ends separately.
