How to measure steps?
There are well documented rules of thumb in terms of ideal step dimensions, and what might be termed ‘step psychology’, for example: 1 Steps should be uniform in height and width, and in straight steps, depth. 2 The minimum height should be 100mm (4”) – anything less is usually considered a trip hazard. 3 The absolute maximum height – for comfort – should be 200mm (8”) – this would probably be too high for people who want to frequently carry food and drink in and out of a house e.g. to a socialising area down the garden. 4 The aim is to create a good rhythm for people when walking up and down steps, so a lower riser height (e.g. 100mm) is usually accompanied by a deeper tread depth (say, 500mm), and vice versa – so a riser height of 200mm would normally be associated with a shallower tread depth (say 250mm). 5 Narrow steps tend to impart a sense of haste and urgency, as do shallow, steep steps; wider, deeper steps tend to feel more unhurried, safe and relaxed (and are potentially also a place to arrange containers!).
