Bra Size Calculator India
Find a practical starting size using your underbust and bust measurements. Then check the band, cups and fit—before choosing a bra.
No signup Inches or centimetres Fit guidance after result
A bra size estimate is a first size to try—not a guarantee of fit in every brand or style. Our quick model supports a limited band and cup range and explains when it cannot calculate.

How to measure your bra size
All you need for the quick calculator is a soft measuring tape and two measurements. The photographs show tape placement as a general example; they are not personalized fitting instructions.
Step 02
Measure your standing bust
Wrap the tape around the fullest part of the bust. Keep it horizontal without flattening the tissue.
- Keep the tape horizontal at the back
- Avoid squeezing or compressing the bust
- Use an unpadded bra if it helps support a natural shape
Before measuring: Stand naturally, keep the tape untwisted, and ask someone for help if you cannot keep it level at the back.

After calculating
Check the fit in 10 seconds.
The label is a starting point. How the bra feels and moves matters just as much.
Band stays level
It should feel comfortably snug and stay in place without riding up.
Cups feel right
Look for gaping, spillage or uncomfortable pressure.
Nothing digs in
Straps and wires should feel supportive, not painful.
Persistent or new breast pain and changes should be discussed with a healthcare professional.

How the estimate works
Clear numbers. A better starting point.
The calculator uses a simplified UK-style band-and-cup model. It is a guide for choosing a first size to try—not a professional fitting or a medical assessment.
See the India bra size chart1. Band estimate
Underbust is converted into inches and rounded to a supported even-numbered UK-style band.
2. Cup estimate
The difference between standing bust and the estimated band determines the starting cup letter.
3. Comfort options
Snug, Regular or Comfort can adjust the band suggestion. The result explains when an adjustment changes the label.
4. Honest limits
The quick model supports bands 28–44 and cups AA–H. Unsupported combinations show a message instead of a forced size.

Helpful answers
A few things worth knowing.
Sizing can take a little trial and adjustment. These answers can help you make a more confident next choice.
How do I calculate my bra size at home?
Measure snugly around your ribcage below the bust, then around the fullest part of the bust. Enter both numbers in the same unit. The calculator estimates an initial UK / India-style band and cup label.
How accurate is a two-measurement bra size calculator?
It offers a useful starting estimate, not an exact fitting. Band elasticity, cup shape, body shape, brand charts and how you measured all affect the size that feels best.
Why is the result different from the size I already wear?
Different sizing methods and brand charts can produce different labels. First check that your measurements are correct, then assess whether the new band stays level and the cups feel comfortable.
Should I measure with or without a bra?
An unpadded, supportive bra may help some people take a standing bust measurement. Others may be comfortable measuring without one. Avoid padding or compressing the bust.
Why do Snug, Regular and Comfort sometimes give different sizes?
The preference changes the band allowance in this simplified model. When the band changes, the calculator may adjust the cup letter to approximate a similar cup volume. It is an option to try, not proof that one preference is the correct fit.
What if the calculator cannot give a size?
This quick model currently supports UK-style bands 28–44 and cups AA–H. Some measurements or comfort adjustments fall outside its supported range. The tool will explain the limitation instead of guessing. A brand chart or specialist fitting can help with other ranges.
Is Indian bra sizing the same as UK or US sizing?
Indian retailers often use UK-style band and cup labels, but there is no universal brand-independent mapping. Check the specific retailer's chart, particularly for cups above D.
What if one breast is larger, or the bra still feels uncomfortable?
Some asymmetry is common. Try fitting the larger side first, then adjust the smaller side if needed. If a bra gaps, digs in or rides up, compare its style and construction as well as its size. Seek medical advice for persistent pain or concerning changes.
