Overweight Calculator
Find your BMI category and the exact weight where overweight begins for your height, based on calculator.net guidance.
Choose your units
Enter height and weight to see BMI category and the weight where overweight begins.
How the overweight calculator works
The calculator uses your height and weight to estimate BMI, then maps the result to standard BMI categories. The overweight threshold is the weight that corresponds to a BMI of 25 for your height, and obesity begins at BMI 30. This aligns with the calculator.net approach and global WHO guidance for adults.
BMI category table
| Category | BMI range | What it means |
|---|---|---|
| Underweight | Below 18.5 | Below the healthy range |
| Normal | 18.5–24.9 | Healthy range for most adults |
| Overweight | 25–29.9 | Above the healthy range |
| Obese | 30 and above | Higher health risk range |
Why overweight thresholds matter
Knowing the exact weight where overweight begins can help you set realistic goals. If your BMI is above 25, you can estimate how much weight you would need to lose to return to the healthy range. If your BMI is below 25, the cutoff shows how much headroom you have before entering the overweight category.
BMI limitations to remember
- It does not account for muscle mass, bone density, or fat distribution.
- Athletes and lifters may score higher without elevated body fat.
- Older adults may have normal BMI with higher fat mass due to muscle loss.
Next steps after your result
If you want to act on your result, pair your BMI with measurements like waist circumference, activity level, and how you feel day to day. BiteCheck can help you log weight changes, plan meals, and monitor trends over time.
FAQ
What does the overweight calculator do?
It calculates your BMI from height and weight, then shows the weight where BMI 25 (overweight) and BMI 30 (obesity) begin for your height.
Which BMI categories do you use?
We use WHO BMI cutoffs: under 18.5 is underweight, 18.5–24.9 is normal, 25–29.9 is overweight, and 30+ is obese.
Can I use metric or imperial units?
Yes. Enter centimeters/kilograms or feet/inches/pounds and the calculator converts automatically.
Is BMI the same for athletes?
BMI does not measure body fat directly. Athletes with higher muscle mass may fall into overweight categories despite low body fat.
Why do thresholds matter?
The thresholds show the weight where BMI categories change for your height, which helps you set realistic targets and monitor risk changes.
Should I use this as medical advice?
No. This calculator is informational. Talk with a clinician for personalized guidance or if you have health concerns.
