I know Americans in generally are fatter than most of the world, but
does this apply to our hands as well?

Variations in hand sizes follow shoe sizes.  The local hardware store
has a wide variety of work and gardening gloves.  Mostly, I use gloves
for firewood handling.  Unfortunately, the only gloves that fit me
properly are Women's Small or Medium.  Men's Small fingers are too
long.  I became somewhat proficient at altering and stitching the
glove fingers, but at about 2 hrs per pair, I gave up and have
resigned myself to wearing pink, purple and flower design leather
gloves.  I have a similar problem with pianos where an octave span is
a stretch.

Scroll down to the table and graph in the middle of the document.
Notice the wide range in hand sizes.  The authors sources of data and
sample sizes are not very good, but does show that there are
differences in hand sizes.

Hand size is also an issue with smartphone screen sizes:
