Printable stair runner length calculator

Run the numbers once, then take them with you. The print view produces a clean one-page specification: your measurements, the calculated length, the materials list and the cost breakdown.

You can also download the figures as a text file or copy them to the clipboard for an email.

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.

What the printed sheet shows

Project and client name if you entered them, every input measurement, the bare and order lengths in your chosen units, the accessory counts, and the cost lines. Site navigation, buttons and form controls are all removed.

Share instead of print

The share button creates a link carrying your figures, so the person you send it to can change a value and see the effect rather than working from a static sheet.

Questions people ask

Can I save it as a PDF?: Yes — use 'Save as PDF' in your browser's print dialog, or download the results as a text file.
