Bra conversion tool
Bra Size Converter
Compare bra size labels across India, UK, US, EU, AU, and FR systems. This converter helps you shop more safely across regions and warns when cup naming becomes less reliable after D cup.
Best for
Comparing imported, marketplace, and cross-region bra labels before you buy.
Key caution
After D cup, UK and US cup naming can diverge. Always read the warning notes shown by the tool.
Important reminder
Converted size labels are a guide, not a guarantee. Brand fit and bra style still matter.
Switching between Indian brands instead? If you want to compare sizes across brands like Zivame, Enamor, Jockey, or Clovia, use the Brand Size Converter.

Safe for label comparison
Use this to compare labels across systems before you buy.
Not a fit guarantee
If the converted size still feels off, use sister sizing or fit troubleshooting next.
Global equivalents
Based on your input of 34C (India), here is the closest label comparison across systems.
Low-friction conversion zone
This size range usually converts more cleanly across systems, though brand variation can still affect fit.

Practical reminder
Label conversion is only step one. If your converted result still feels wrong, compare a sister size, check the bra shape, and remember that imported brands often fit differently even when the label appears equivalent.
Before you use the bra size converter
• Convert the label first, then judge the bra by real fit, support, comfort, and cup behavior.
• Treat brand variation and size-system conversion as two separate issues.
• Be more cautious after D cup, where UK and US naming often diverge.
• Use sister sizing or fit troubleshooting if the converted size still feels wrong.
Why this tool matters
Bra size conversion is useful, but post-D labels are not as universal as people think.
A label that looks equivalent on paper can still feel different in real life. That is especially true when shopping across Indian brands, imported labels, marketplace listings, lingerie boutiques, and mixed international size charts.
This bra size converter helps you compare size systems more safely and understand where the naming becomes less trustworthy after D cup.
For many smaller cup sizes, conversion is fairly straightforward.
After D cup, UK and US cup naming often diverges, and brands may label similar practical sizes differently.
That is why a bra size converter should not only show equivalent labels. It should also warn where direct conversion becomes less reliable.
Use the converter as a guide, then confirm with fit feedback, sister sizing, and brand context.
How to read the result
Use the converted label as your closest comparison point, not as a blind promise.
A good bra size conversion tool should make cross-region shopping easier, but it should also make you more careful where labels become ambiguous, especially across UK, US, EU, AU, FR, and India-facing listings.
Closest label match is the starting point
The converter helps you identify the nearest equivalent bra size label in another region. That is useful for shopping, but not the end of the decision.
Post-D conversions need extra caution
Once you move into fuller-bust cup naming, similar practical sizes can appear under different labels depending on whether the brand leans UK or US.
Fit still matters after conversion
Even a technically correct conversion can fail if the bra style, stretch, wire shape, or cup construction runs differently from what you usually wear.
Use nearby tools when the result feels off
If the converted bra size seems close but not quite right, sister sizing or a fit check is often more useful than trying random labels.
Best use case
Use bra size conversion to compare labels across regions, not to assume every converted size will fit perfectly in every brand.
Safe zone
Smaller and simpler cup ranges usually convert more cleanly across India, UK, US, EU, AU, and FR systems.
Divergence zone
After D cup, naming differences between UK and US labels become much more confusing. Use the tool’s caution notes instead of trusting the first label blindly.
Common conversion examples
These examples make it easier to compare common bra sizes across India, UK, US, EU, AU, and French systems before you buy from another region.
Simple example
India/UK 32C → US 32C → EU 70C → AU 10C → FR 85C
Common fuller-bust example
India/UK 34DD → US 34DD → EU 75E → AU 12DD → FR 90E
Caution example
India/UK 36E may appear as 36DDD or 36F in some US brand contexts depending on the label system.
India shopping note
Indian shoppers often see mixed bra size systems on:
Imported lingerie brands
Marketplace listings with copied charts
Brand pages that mix UK and US naming
International content that assumes US labels
Convert the label first, then use fit logic if the result still feels off.
Open sister size calculator
Best when the conversion looks close but the band feels too tight or too loose.
View conversion guide
Best when you want a chart-style reference alongside the tool result.
Check bra fit problems
Best when the converted bra still gaps, spills, pokes, rides up, or feels unstable.

FAQ
Bra size converter FAQ
Common questions about bra size conversion across India, UK, US, EU, AU, and FR systems, including label differences, post-D cup confusion, and what to do when the converted bra size still feels wrong.
Does a converted bra size always fit exactly the same?
No. Conversion helps compare labels, but the real fit can still vary by brand, bra style, wire shape, stretch, cup construction, and overall bra design.
Why do UK and US cup labels become confusing after D?
After D cup, many systems stop naming cups the same way. A UK E may appear as DDD or F in some US contexts depending on the brand. That is why this page warns you more strongly in the post-D range.
Is India sizing closer to UK or US sizing?
For many practical shopping situations, Indian sizing is easier to compare with UK-style band and cup progression. But imported bras and marketplace listings may still use US-style labels.
Why does EU sizing look so different?
EU uses a different band numbering system, so the same practical bra fit can look very different on the label even when the cup relationship is similar.
What is French bra sizing?
French sizing usually uses the same cup lettering style as EU sizing, but the band number is typically EU band plus 15. For example, EU 75 often corresponds to FR 90.
What should I do if the converted size still feels wrong?
Use the conversion as a guide, then check the fit. Sometimes a sister size, a different bra style, or a brand-specific adjustment is more useful than a direct bra size conversion.
Is this converter useful for online shopping in India?
Yes. It is especially helpful when comparing imported bras, shopping on marketplaces, or moving between Indian, UK, US, EU, AU, and FR labels.
Can the same label convert correctly but still fit badly?
Yes. A mathematically close conversion can still feel off if the bra runs tight, shallow, narrow, tall in the cup, or simply uses a construction that does not suit you.
Best way to use this tool
- Start from the bra size you already wear or the size you measured most recently.
- Use the converted label as a comparison point, not as a guarantee of perfect fit.
- Be more careful in fuller-bust ranges where UK and US cup naming often diverges.
- If the converted size feels close but not quite right, check sister sizing or fit issues next.
Conversion has limits
Bra size conversion is a practical label-comparison tool, but it cannot fully account for brand fit, bra style, cup shape, wire width, stretch, support distribution, or construction differences.
That is why the best bra size converter helps you compare labels clearly, then encourages real fit judgment afterward.
Next step
Need your likely size before converting?
Direct bra size conversion works best after you already know your likely starting size. Measure first, then compare labels across systems more confidently.
