    I prefer those electrical ones that actually tell your density. I have really, really dense bones, so the measures are always off for me by a lot. even when I was a competing athlete, my weight and height said that i was obese! I could stand to lose weight now I know, but at 5’4″ and 180lbs, you’d think I’d be way bigger than a size 8. I want to get back to a 4 or 6.

  • Janine

    WebMd is very useful, nice to know it also has a BMI calculator! I’ll have to go and check out the page and calculate my own. I don’t worry about my weight, but eh, curiosity 🙂

  • Larisa

    Didn’t know the CDC had one of these calculators! The more you know! It’s nice that it has separate ones for age groups!

    • Phil

      The CDC definitely should have one, being that the link between obesity and diabetes is so strong, and diabetes is at almost epidemic proportions.

  • Duke

    Nice article! There are lots of BMI calculators out there. I suggest sticking with just one to track your progress though, for consistency.

  • Christina

    I usually use the NINH to check, very simple and easy to use, not too fussy. I check my BMI regularly, as I’m just an average girl trying to keep her weight in a healthy range (while battling my raging desire for carbs)

    • Luther

      No desire for carbs, but for some reason stress makes me gain weight at an alarming weight. it’s always good to check, I weight in after my workouts every other day.

  • Julie

    Eh, BMI is only accurate for average people. If you’re a very fit person with lots of lean mass but low bodyfat, you’re pretty much screwed, as you’ll show up as “obese”. I think a body fat calculation is a better tool than a BMI.

    • Steph

      I agree. There’s a lot more factors than just weight and height, especially for those of us who build muscle easily. Where can the average person get more intensive tests, without paying an arm and a leg?

  • Angie

    Thanks, this is very important to know. Sometimes people are naturally big boned and muscular which can make the true BMI for them inaccurate so how is that worked with these tools? I hope its not a silly question, i will need to give this a try myself.

    • Xavier

      I think it’s good to know the running average though. I wish the doctors would do tests for bone density at physicals and stuff though. Do they? Mine never have.
