📖 Overview
Use this upgraded calculator to combine BMI with waist-based context for better screening insight.
⚙️ How It Works
This combines BMI with waist-to-height ratio to add abdominal-risk context.
The Formula
BMI = Weight (kg) ÷ Height (m)² | Waist-to-Height Ratio = Waist (cm) ÷ Height (cm)
| BMI | Body Mass Index screening metric |
| Waist-to-Height Ratio | Central adiposity indicator; < 0.5 generally considered lower risk |
⚠️This tool provides a screening estimate only. Neither BMI nor waist-to-height ratio is a diagnosis. Consult a healthcare professional for personalised health assessment.
Quick Reference
| Waist-to-Height | Risk Level | Notes |
|---|---|---|
| < 0.40 | Very low | Very lean, possibly underweight centrally |
| 0.40 – 0.49 | Low | Healthy central fat distribution |
| 0.50 – 0.59 | Elevated | Increased cardiometabolic risk |
| ≥ 0.60 | High | Strong indicator of abdominal obesity |
Practical Tips
💡 Track both indicators over time, not one-off values.
💡 Use consistent measurement conditions for repeat checks.
Frequently Asked Questions
❓ Why include waist ratio?
Central adiposity can add risk insight beyond BMI alone.
❓ Is this diagnostic?
No, it is a screening estimate and should not replace clinical assessment.
