Are you overweight?  Maybe Body Mass Index says you are, but actually you are not. BMI can be wrong. Look at the weight percentiles, because they adjust for age.

The older you get, the higher your BMI is allowed to be. For example, in people over age 50, BMI of 25 to 30 is still normal and very healthy. I also believe the 45th percentile weight is a good estimate of your ideal weight.

Also, these height and weight charts and BMI charts show what the average population is like.

Why do I have two versions of a BMI calculator on halls.md? It's a leftover from year 2000, and I can't bring myself to delete old pages. So this page reminds me of the old-school html with tables, while the main BMI calculator is where new features will continue to appear.

Way back in year 2000 when I created all this BMI stuff, calculators and analysis and custom formulas, the CDC was lagging. But to their credit, the science and their webpages and calculators have become quite good. You can unfortunately still find rigid categories on CDC pages like this but, they have more useful things like a BMI percentiles calculator for children, which, reminds me to mention because it's not obvious: my Weight Percentiles calculator is VERY equivalent to a BMI percentile.

Recently I've been looking at other BMI calculators, for instance at Mayo Clinic, which disappoint me, not only because of the ads for their branded diet, but they refer to a 2013 WHO report, where various academics still lump together overweight and obesity into 'combined', which of course is less healthy than normal weight. Whenever you read a study abstract where the word "combined" is used in confusing ways, that's deliberate tricky wordsmithing.
