US and Foreign Bra Sizes

As almost all women know, bra sizes usually consist of a number which tells the band size, and one or more letters that tell the size of the cup.  Bra sizes vary widely by manufacturers and countries. So if you’re abroad shopping, finding your actual bra size can be confusing and time.

The designers of intimate apparel use different bra sizing systems, and international sizes may not be familiar to you. So, to make things easier, use the size conversion chart below to convert US bra sizes into the UK, European, Australian, French, and Italian.  You must first familiarize yourself with the symbols used in the chart.

                        US       =          United States

                        UK      =          United Kingdom

                        EU       =          Europe (also, Japan)

                        AU      =          Australia (also, New Zealand)

                        FR       =          France (also, Spain and Belgium)

                        IT        =          Italy (also, Chez Republic)

As mentioned before, bra sizes may vary also by manufacturer, so the conversion table below can only give an estimate of your bra size.  Here’s the chart, which converts both the band and cup sizes.

US	UK	EU	AU	FR	IT
34A	34A	75A	12AA	90A	2A
34B	34B	75B	12A	90B	2B
34C	34C	75C	12B	90C	2C
34D	34C	75D	12C	90D	2D
34DD/E	34DD	75E	12D	90E	2E
34DDD/F	34E	75F	12DD	90F	2F

Follow the sequence, and we jump to US size 44:

US	UK	EU	AU	FR	IT
44AA	44A	100A	22AA	115A	7A
44A	44A	100A	22AA	115A	7A

44C	44C	100C	22B	115C	7C
44D	44D	100D	22C	115D	7D
44DD/E	44DD	100E	22D	115E	7E
44DDD/F	44E	100F	22DD	115F	7F
44F	44F	100G	22E	115G	7G
44G	44G	100H	22F	115H	7H
44H	44H	100I	22G	115I	7I

From the above chart, you will notice that UK bra sizes are similar to the US bra sizes, e.g., a US 34A bra is the same as the UK 34A bra. Another thing to point out is that US bra sizes never go beyond DDD cup sizes; and some brands use E for a DD and F for a DDD.

Here are simple charts to convert the band and cup sizes among US, UK and Europe sizes.

Band Conversion Chart
Europe	70	75	80	85	90
USA	32	34	36	38	40
UK	32	34	36	38	40

 

Cup Conversion Chart
Europe	A	B	C	D	E	F	G	H
USA	A	B	C	D	DD or E	DDD or F	G	H
UK	A	B	C	D	DD	E	F	FF

Japanese bra sizes also use the European sizes, although the Japanese cup size is written before the band size. For example:  C75, instead of 75C.

The bra industry has no standardized sizing, so the issue on how loose or tight the band is cut is always there.  You might find a brand with firmer and tighter materials, compared to another brand with band easily stretch.  You might even get more confused if you find that some US brands are using the UK bra sizing system.  So if you are looking to buy your bras online, make sure that you are aware about the bra sizing method used by the manufacturer.  A UK bra cup measuring an H is bigger than a US H cup by 3 sizes.  It’s really important that you know how a particular brand sizes their bra items.
