Find Your Clothing Size in Seconds
Use your measurements to get a quick estimate for top and bottom size. You can switch between metric and imperial units.
How This "My Size Calculator" Works
Clothing sizes can feel random across stores, but there is still a practical way to make better first guesses. This calculator uses your basic body measurements—chest, waist, and hips—then compares them to a general threshold model used by many apparel brands. It then recommends a top size, a bottom size, and an overall size starting point.
We also calculate your BMI from height and weight, not to define your health, but to provide additional fit context (for example, whether a relaxed fit might feel more comfortable than a slim cut in some garments).
How to Measure Correctly
1) Chest or Bust
Stand naturally and wrap a soft measuring tape around the fullest part of your chest or bust. Keep the tape level with the floor and comfortably snug—not tight.
2) Waist
Measure at your natural waistline, usually just above your belly button. Do not hold your breath or suck in your stomach, since that leads to smaller-than-real measurements and poor fit.
3) Hips
Measure around the widest part of your hips and seat. Keep feet close together for consistency.
4) Height and Weight
Enter height and weight as accurately as possible. If you are between values, rounding to one decimal place is fine.
Recommended Size Logic (Quick Reference)
The calculator maps measurements to a simple size ladder. Different brands vary, but these ranges are a useful baseline:
| Size | Approx. Chest/Bust (cm) | Approx. Waist (cm) |
|---|---|---|
| XS | Up to 86-89 | Up to 66-74 |
| S | 90-97 | 75-82 |
| M | 98-104 | 83-90 |
| L | 105-112 | 91-98 |
| XL | 113-120 | 99-106 |
| XXL | 121-128 | 107-114 |
| 3XL | Above 128 | Above 114 |
Interpreting Your Result
- Top Size: Driven mainly by chest or bust measurement.
- Bottom Size: Based on the larger requirement between waist and hips.
- Overall Starting Size: The larger of top/bottom to avoid buying too small.
If your top and bottom sizes differ, that is completely normal. Many people are between sizes or have different proportions. In those cases, prioritize fit in the area that matters most for comfort and movement.
Tips for Better Online Shopping Fit
- Compare your measurements with each product's own size chart.
- Check if the item is listed as slim, regular, or relaxed fit.
- Look at fabric stretch (e.g., elastane blends can allow a closer fit).
- Read reviews for comments like "runs small" or "true to size."
- If between sizes, choose based on preferred fit: tighter look vs. easier comfort.
Final Thoughts
A size calculator cannot replace trying clothes on, but it can dramatically reduce guesswork. Use this tool as a starting point, save your current measurements, and update them every few months. Consistent measuring and smart comparison across brand charts is the fastest way to buy better-fitting clothes with fewer returns.
