I'm only 5 feet tall but weigh 105. I never used to worry about it, but my sister who is 10 years older than me looks a lot thinner than me. So does her 6"3 husband. I'm a teenager so it's clearly not "puppy fat"?

Endomorph, mesomorph, ectomorph, Small boned, large boned, genetics, current age, age plus a few more factors involved.

Nothing to be embarrassed about---talk to your mom and sister.

I'm sure your weight is fine.  Don't compare yourself to anyone else.  If you're concerned though .. Ask your doctor.  You are a teenager and still growing.  You should be concerned about being healthy and feeling good.

You are at an ideal weight for your height. And quit comparing yourself to others. There are so many factors that go into one's build, you cannot make a true comparison.
