Preferred Handrail Height for Spiral Stairs—A Fitting Trial Study

Sinisammal J., Saaranen P.

International Journal of Occupational Safety and Ergonomics

2010

Vol. 16, No. 3

329--335

Stairways are, in general, a thoroughly studied subject, but there is almost no scientific data available about spiral stairs. They are, however, widely used in homes, industrial sites and public buildings. The purpose of this study was to determine preferred handrail heights for a spiral stairway. The most preferred handrail height for descent was 105 cm. On the other hand, 95% of the participants regarded handrail heights between 95 and 100 cm satisfactory for descending. Participants’ anthropometric data was combined with the handrail height preference to develop a draft of a model to predict preferred handrail height for other user populations.
