Asking your girlfriend or wife to guess your size is probably going to be quite inaccurate, as in my experience women often have difficulty explaining the size of something without actual measurements.Also In my line of work, housewives bring in room dimensions and suprisingly often they get metric and imperial measurements confused or combine the two in one measurement from the same tape measure?!
If you then ask them to describe the room in approximate terms, they often get it wrong!...A 20ft long room turns out to be only 15ft long when actually measured!
