A BMI number on its own — "24.1" — doesn't tell you what to do . The free BMI calculator now answers the follow-up questions most calculators skip: what's a healthy weight for my height, what's my ideal weight, how much do I need to lose or gain, and is BMI even the right metric for me?

Your healthy weight range and ideal weight

A healthy BMI is 18.5–24.9, which maps to a specific weight range for your height. Instead of leaving you to do the algebra, the calculator shows:

Your healthy weight range (in kg, pounds, or stone)

A target weight at BMI 22 — the middle of the healthy band

Exactly how much to lose or gain to get into range

So "24.1, Normal" becomes "you're in the healthy range" — or "lose about 6 lb to reach it."

A visual gauge, not just a number
