I see 10.5 stone searched a lot by people who have just stepped off a metric scale and want the number in words they grew up with. It is also a classic half-stone milestone on weight charts, the sort of figure people write on the fridge when they are working downwards from 11 or 12 stone. Height still decides what it means: at 5ft 6in the BMI is 23.6, mid-range; at 5ft 4in it is 25.1, a shade over. The table below lays it out height by height.

One thing I always tell people: half a stone sounds like a lot until you spread it across a height range. The same 66.68 kg gives a BMI of 27.1 at 5ft 2in and 19.9 at 6ft 0in. That is the difference between overweight and healthy from the identical reading on the scale. Find your height in the table and read across.

If you are between those heights, the tape measure tells you more than another weigh-in will. BMI is a screening measure rather than a diagnosis, because it says nothing about build or muscle.
