How this page helps

This page helps you compare bra sizes across common systems like India, UK, US, EU, and FR so you can read labels more confidently and shop with fewer size mistakes.

Method

The guidance on this page is based on standard label mapping across major bra-size systems, plus practical fit context where country naming and post-D cup progression can vary by brand.

Quick answer

A bra size conversion chart helps you compare the same approximate size across systems like India, UK, US, EU, FR, and AU.

The safest method is to convert the band number and cup letter separately. This matters most when a bra tag shows multiple systems or when you are shopping imported lingerie online.

Band numbers may switch between inches and centimeters
Cup letters match fairly well only up to D
After D cup, country systems can diverge a lot

Best first step

Start from a size you already trust.

If you do not know your current size confidently, measure first instead of converting a guess.

Bra size conversion gets confusing because countries do not use one universal system. Band numbers may be shown in inches or centimeters, and cup letters may look similar only up to a point. This guide helps you compare sizes across India, UK, US, EU, FR, and AU more confidently. If you do not know your starting size yet, begin with our bra size calculator or the bra measuring guide before using the tables below.

Start here based on your situation

The Global Sizing Rule

There is no universal standard for bra sizing. Different regions label the same approximate fit in different ways. Band numbers may be shown in inches or centimeters. Cup letters often match from A to D, but after D cup the naming systems start diverging. That is why the same bra volume may be labelled as UK E, US DDD, or EU F depending on the brand.

How to Use This Chart

1
Start with the bra size you already know or trust most.
2
Split it into two parts: band size (number) and cup size (letter).
3
Use the first table to convert the band number across countries.
4
Use the second table to convert the cup letter across countries.
5
Combine both parts to get your closest equivalent size in another system.
6
Then let actual fit decide whether you should keep it or adjust nearby.

Simple rule: convert the label first, then judge the bra on fit. A technically correct conversion can still feel off if the band runs firm, the cups run shallow, or the style shape does not suit you.

Global Band Size Conversion

Use this chart to convert the number part of your bra size. India usually follows the same familiar band numbering as the UK, so UK or IN is often the easiest reference point for Indian shoppers.

UK / India / US
(Inches)
Europe / Japan
(Centimeters)
France / Spain
(+15 to EU)
Australia / NZ
(Dress Size)
2860756
3065808
32708510
34759012
36809514
388510016
409010518
429511020
4410011522

Useful shortcut: if a tag shows EU 75, think UK / India 34. If it shows EU 80, think UK / India 36.

Quick Conversion Examples

EU 75C → UK / IN 34C
EU 80D → UK / IN 36D
FR 90C → UK / IN 34C
FR 95D → UK / IN 36D
AU 12C → UK / IN 34C
AU 14D → UK / IN 36D

The "D-Cup" Divergence

Up to a D cup, most systems look similar. After D, the naming often splits. US brands may use labels like DD, DDD, F, while UK sizing usually follows a more systematic sequence like DD, E, F, FF, G. This is the biggest reason many shoppers convert larger cup sizes wrongly.

* The rows highlighted after D cup matter most. This is where many size-conversion mistakes happen, especially when moving between UK and US labels.

If Your Converted Size Still Feels Wrong

A correctly converted size can still feel wrong in real life. That does not always mean the chart is bad. It often means the bra itself runs differently.

Band feels too tight or too loose

Try a nearby sister size instead of abandoning the conversion entirely.

Cups feel too shallow or too tall

The shape of the bra may be the problem, not just the label.

Brand uses unusual cup naming

Check whether the brand follows UK, US, or EU progression after D cup.

You converted from an old bra label

Fresh measurements may give a better starting point than an old tag.

Best mindset: use conversion charts to translate labels, not to force perfect fit. The label gets you close. Actual fit tells you what to do next.

Which Countries Commonly Use Which System?

Sizing systemCommon countries / use cases
UK / IndiaUnited Kingdom, India, and many brands sold widely in Indian retail
USUnited States brands and stores using American cup progression
EUGermany, Netherlands, Poland, and many continental European brands
FR / ESFrance, Spain, and labels that add 15 to the EU band number
AU / NZAustralia and New Zealand, often using dress-style band numbers

If your converted size still feels confusing, compare it with our Indian bra size chart, check nearby sister sizes, or revisit your measurements using the measuring guide.

Frequently Asked Questions

Are UK and US bra sizes the same?

UK and US bra sizes are usually the same for band numbers and for cup letters from A through D. After D cup, the systems start diverging. For example, a UK E cup is often closest to a US DDD or F depending on the brand.

What is an EU 75C in UK sizing?

An EU 75C usually converts to a UK or Indian 34C. The EU band number is centimeter-based, while the UK band number uses the familiar 32, 34, 36 style most shoppers in India recognise.

What does DDD mean in US sizing?

DDD is a US cup label used after DD. In many conversion charts, a US DDD lines up with a UK E cup, but some American brands use slightly different naming after D cup, so it is worth checking brand-specific notes too.

Why do French bra sizes have such high numbers?

French and Spanish band numbers are higher because they add 15 to the standard EU band size. So an EU 70 becomes FR 85, and both usually correspond to a UK 32 band.

Is Indian bra sizing the same as UK sizing?

Most bra brands commonly sold in India follow UK-style sizing, especially for band numbers and cup progression. That is why UK or IN is usually the best reference point when reading imported labels in India.

Should I trust the converted label or the actual fit?

Use the converted size as a starting point, then let actual fit decide. If the band rides up, cups gape, cups spill, or the shape feels wrong, adjust using fit signs or nearby sister sizes instead of forcing the exact converted label.
