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.

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.

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

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 speeds up a site visit

Regional presets fill typical dimensions in one tap so you only change what is different. Fractional entry means you can type what you read off the tape. The share link puts the same figures on the office computer before you get back.

The quote

Add labour per step, accessories, delivery and tax, and print. The print view drops the site navigation and form controls and leaves a clean specification with the project and client fields you entered.

  • Runner, underlay and accessory lines
  • Labour and delivery
  • Tax or VAT
  • Total and cost per step

Numbers you can defend

Every allowance is explicit — waste percentage, nosing allowance, landing depths — so if a client questions the quantity you can show exactly where it came from.

Questions people ask

Can I save several staircases?
Yes. Save each one with a name; they are stored in your own browser and can be reloaded or deleted at any time.
Can I print a quote for a client?
Yes. Enter a project and client name and print — the output is a clean specification without site navigation or form controls.
