Measuring a staircase accurately
Stairs are measured tread by tread rather than as a simple length by width calculation, because winders, half landings and varying tread depths all affect how much carpet is needed and how it is cut.
- Tread depth and riser height are recorded individually where a staircase is not perfectly uniform
- Extra allowance is normally included for pattern matching or for future re-laying further down the flight
- A free measure at the property is the most reliable way to get an accurate figure rather than estimating from room dimensions alone
