Body Fat Percentage?

Options
Hi everyone,
I've been doing the atkins diet for 2 and a half weeks and i've lost 10 pounds so far, making me about the 160 pounds mark. I just recently calculated my body fat percentage and it's 26%. I'm just a touch under 5 foot 6 and was just wondering how this fat percentage measures up in terms of my weight/height/age (I'm 19).

It's not something i've ever calculated but after reading about how BMI calculations can be a little bit off and sometimes not helpful, I wanted to find something else to go off of whilst I'm losing weight.

Any help or advice? Thanks!
