Is 5'5 tall for an 11 year-old girl?

My friend is a bit concerned and Is wondering if her daughter is at a normal height for her age. She's also skinny even though she eats a lot; doesn't gain weight. No period yet.

Note: She's 5'11, her husband is 6'4 and most of the family members (both genders) are very tall.

Is that tall for a girl that age?
