Rule of thumb is an English phrase that been in common use since the 17th century. It describes a method of doing things which, although not scientifically verified, is broadly correct but may not strictly accurate or reliable in all applications, even though it may have proved successful on past occasions.

Its derivation was thought to be from an old English ruling that set the maximum width of a stick a man could beat his wife with to be no wider than his thumb. However, there is no such evidence for this and so the origin of the phrase remains uncertain.

It may be that a rule of thumb is eventually proved in science to be correct, upon which it continues to be used but the likelihood is that it will still be referred to as a ‘rule of thumb’ – see below.

Builders of the past would have used rules of thumb in construction. Gothic cathedrals eventually would soar in height as master masons learned through experience to understand certain relationships e.g, the height of a tower in relation to its base and wall thickness; the depth of foundations according to soil conditions, or the diameter and spacing of piers to support the masonry above.

Advancement would typically be through making mistakes and learning from them. A classic example is the collapse (in 1237) of the main tower at Lincoln Cathedral, and the collapse (1210) of the south-west tower of Chichester cathedral followed in 1635 by the collapse of its north-west tower.

Rules of thumb are still used today by construction professionals as they can give a basis from which a more detailed design may be delivered. Examples are:

The Evans rule, which arose out of a Royal Academy of Engineering paper by Evans et al: the 1:5:200 ratio. This states that if initial building construction costs are ‘one’, over the years ‘five’ will be the operating and maintenance costs, while ‘200’ will be business operating costs.

Health and Safety Executive: in assessing noise risks for large, dynamic sites …’as a general rule of thumb, the noise level is probably 80db or more if the noise is intrusive but normal conversation is possible between people 2m apart – comparable to a busy street, a typical vacuum cleaner or a crowded restaurant.

Rules of thumb may also be used by engineers in steel construction, architects, quantity surveyors and other construction professionals.
