there are really 2 main types of dwarf
- the ones who have large heads, wide pelvises and distinctive facial features, but with short limbs and hands and are 'out of proportion' compared to an average person.
then there are 'midgets' - so-called because they are in proportion all over and are sort of 'miniature' people.
so i think 'midgets' would have the same thing with the foot and forearm, but i think dwarves have larger feet - just going by the mental image of any dwarves i have met or seen.
i guess with any kind of growth problem, it could go either way.
i am really curious for a definite answer myself now
