Stair runner length calculator with price

If you already have a quote per foot or per metre, this page turns it into a real number in seconds. Enter the rate, pick the unit, and the material cost appears next to the length.

Currency options cover USD, GBP, EUR, CAD and AUD, and the tax field handles sales tax, VAT or GST.

Your staircase

Start from typical stair sizes where you live

IRC-style stairs: 10 in minimum tread, 7¾ in maximum riser. Runners are usually 27 in or 32 in wide and sold by the linear foot.

Number of stairs

Count every step you will cover.

Tread depth (in)

Front edge to back of the step. Fractions like 10 1/2 work.

Riser height (in)

The vertical face between two treads.

Waste allowance

Custom%

10% is a common starting point; pattern matching and winders need more.

Add a nosing / overhang allowance per step

Needed when the runner wraps around a projecting nose (Hollywood installs and thick pads). Waterfall installs usually don't need it.

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

Your measurements, drawn to scale

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.

Pricing units explained

Per linear foot and per linear yard are the US and Canadian norm; per linear metre is standard in the UK, Europe and Australasia. Per inch appears occasionally on made-to-order runners. Choose the one on your quote — the calculator converts internally.

What price to expect

Rather than quoting made-up averages, use two or three real supplier prices in the field and compare the totals. The share link lets you send each version to a client side by side.

Tax, delivery and the true total

A long runner is heavy and delivery is rarely free. Enter it as a flat figure and set your tax rate so the total on screen is the total on the invoice.

Questions people ask

Which pricing unit should I choose?: Match your supplier's quote exactly — per linear foot, per linear yard, per linear metre or per inch. Mixing them up is the single most common costing error.
Can I include VAT or sales tax?: Yes. Enter your rate in the tax field and the estimate shows the tax-inclusive total.
