The spread from 20-25 shows that what is normal covers quite a big range. This is because ‘normal’ weight for height covers both men and women, and people of different shapes and body composition. A man would normally be expected to have a higher BMI than a woman of the same height, because men tend to have more muscle than women (women naturally have more fat) and muscle weighs more per square inch than fat. For the same reason a slim, muscular woman will have a higher BMI (i.e. weigh more) than a slim, not very muscular woman of the same height.
