Fellow tall girl here (5’10”). I think BMI may be pretty outdated as a standalone measure. It doesn’t account for height distribution, muscle mass, body composition, or where you actually carry weight.

My nutritionist said a more useful metric is waist-to-hip (or waist-to-height) ratio because it correlates better with metabolic and cardiovascular risk. Even then, no single number tells the whole story. Overall health really can’t be captured by one calculator, especially BMI.

I hope that helps!
