Ideal Waist Size Calculator
Estimate ideal waist size from height and compare your current waist with practical upper-target thresholds.
Common target zone used for practical waist screening.
| Height | Ideal / Upper Target Waist |
|---|---|
| 150 cm | 69 / 75 cm |
| 155 cm | 71.3 / 77.5 cm |
| 160 cm | 73.6 / 80 cm |
| 165 cm | 75.9 / 82.5 cm |
| 170 cm | 78.2 / 85 cm |
| 175 cm | 80.5 / 87.5 cm |
| 180 cm | 82.8 / 90 cm |
| 185 cm | 85.1 / 92.5 cm |
| 190 cm | 87.4 / 95 cm |
| 195 cm | 89.7 / 97.5 cm |
| 200 cm | 92 / 100 cm |
Ideal Waist Ratio Interpretation
Your current waist-to-height ratio is mapped to practical target bands for waist-size planning.
| RANGE | CATEGORY |
|---|---|
| 0-0.40 | Below Common Range Below common adult waist-to-height screening zone. |
| 0.40-0.50 | Target Range Common target zone used for practical waist screening. |
| 0.50-0.60 | Above Target Above the common 0.50 waist-to-height screen threshold. |
| 0.60+ | High High central-fat screening zone from waist-to-height ratio. |
What This Ideal Waist Size Calculator Does
This tool calculates waist targets from your height using two ratios: a stricter ideal-style target and a broader upper practical target of 0.50 waist-to-height ratio.
How to Use These Waist Targets
Treat these values as planning anchors, not strict rules. Waist trend over time is usually more useful than a single reading. If your goal is fat loss, use the upper practical target to set short-term milestones and the stricter target as a longer-term benchmark.
Combine this with the Waist to Height Ratio Calculator and Waist to Hip Ratio Calculator for screening context, then pair with Calorie Calculator and Weight Loss Calculator for action planning.
Measurement Guidance
- Measure waist at the same anatomical point every time.
- Take readings at normal exhale, standing relaxed.
- Keep tape level and snug without compressing tissue.
- Record weekly averages to smooth daily fluid fluctuations.
