Abstract:

If you are more than 95th percentile height or less than 5th percentile, we predict that some everyday objects do not always seem quite the right size for you. Just as you were able to compare your height with others in a given population, it is also possible to make such comparisons for other dimensions such as arm length, hand grip span, seated elbow height etc. Those whose build puts them towards the one extreme or the other will be familiar with the problems of using awkward sized objects.
