Bra Measuring Guide

54 CommentsSunday, 19 June 2016  |  Val

 

There isn't any replacement for obtaining a proper bra fitting in person from a professional bra fitter, but in circumstances where this is not possible, and you really have no idea on your correct size, the guide below can be used to provide a general indication of your bra size.  Please also bear in mind that sizes vary between manufacturers and between different styles of bra. So what fits perfectly in one style or brand, may not in another.

To determine your bra size, you take two measurements -

1. Under bust Measurement
Measure under your bust - Must be a firm, reasonably tight measurement :
if the measurement is an even number of inches this is your band size
if the measurement is an odd number of inches add one inch to get your band size

(For example, if your under bust measurement is 35ins., add 1 inch to obtain bra band size 36, if your under bust measurement is 34ins this is your band size)

2. Bust Measurement
Measure round the fullest part of your bust to determine Cup size.
If the over bust measurement is the same as the figure determined above, your Cup size is A.
1in. more gives Cup size B
2in. more gives Cup size C
3in. more gives Cup size D
4in. more gives Cup size DD
5in. more gives Cup size E
and so on…..

Examples:
Under bust measurement of 32ins. = band size 32
Bust measurement of 38ins. = Cup F

So the correct fitting would be 32F

Under bust measurement of 35ins. + 1 inch = band size 36
Bust measurement of 42ins. = Cup FF

So a guide to the correct fitting bra would be 36FF

 
Problems with you current bra? Are you wearing your correct size?

Bra rides up at back? . . . adjust hook and eye closure to tighten, loosen straps or try a smaller band size (for example 36 instead of 38).

Band digs in? . . . try one band size larger (for example 36 instead of 34) or opt for a bra with a wider band.

Sides bulge? . . . order one band size larger (for example 36 rather than 34) or choose a style that provides more support and cup coverage.

Cups overflow? . . . order one cup size larger (for example C to D) or one band size larger (for example 36 to 38).

Sore shoulders? . . . loosen bra or opt for a bra with wider, or padded straps.

Bustline sags? . . . shorten straps or choose a firmer support style.

Underwires pinch or poke? . . . order one cup size larger (for example C to D) or try a wire free (soft cup) style.

Straps slip? . . . tighten straps or opt for bra with wider straps.

It is really common for ladies to be wearing bras which are two sizes too big round the band - taking the size I have advised as a good starting point, you appear to be wearing three sizes too big. Have a look at our bra fitting guide. Take a reasonable new bra tightened on the loosest hook - is it riding up at the back? This is a good way to determine whether the band is too big. Then pull it in reasonably tight around the band - how do the cups now look? Hope this helps

Hi guys,
I have researched and researched over the internet about the band dilemma, and I still donít have a concrete answer.
Why some calculations add 2 inches to the true chest size? Why others just take the true size and call it the band.....
Anyone knows?
Looking forward to be enlighten
Many thanks
Alex xx


Val

Hi Alex, hopefully I can help. The simple answer is that adding 2 to the band size is the out-dated way of bra fitting. Going back many years, bras were not made in the same way, and of the same materials, as they are now. The material was much less giving and therefore the 2 inches was added to the band for a better fit. Nowadays this is no longer the correct way to determine the size needed and adding 2 inches is no longer required. Unfortunately, some companies are still giving out-dated (incorrect) advice. Hope this helps

Val

Hi Gabi, you need to measure under your bust and then at the fullest part of your bust, which should be a larger number. Have you got the numbers the wrong way round in your question?

Roma

Hi my underbust is 32 exact and fullest part of bust is 38, what would b my bra size? Also please help me I wear a 34D and cup fits but band is loose, also the centre part(gore) doesn't lay flat..how can I fix up my bras, they are new just used once and expensive so I would love to fix the problem and wear them. As I can't just throw them and I can sew so any alterations would be easy for me.


Val
Tuesday, 30 January 2018  |  7:17

Hi Roma, from the measurements you have given you would be a 32F, but as I always advise this is a guide only as brands and styles can vary. As you are wearing a 34 band, the size you should be wearing in this band to get the correct cup volume is 34E, so your cup is essentially two sizes too small. This is why the centre gore isnít laying flat. Are you wearing your bras on the loosest or tightest hook and eye? Wearing on the tightest hook and eye will give a better support, but the cups will feel too small. Wearing on the loosest will allow for a bit more room in the cups, but will not be a good fit. Take a look at our bra fit guide for more advice. Unfortunately there isnít much you can do to get a better fit from the bras you have. You may have read that removing the wires will help, and it is true that by removing the wires you will increase the size of the cup, but you will completely lose all support and shape. Apologies that I cannot offer a fix for the bras you have, but I would definitely try a 32F.

Hi my bra is a 38d but now the cup is big so do I go to 36c


Val
Tuesday, 13 February 2018  |  7:24

Hi Sharon, not necessarily Ė How does the band fit? If the band is still OK (whilst wearing a reasonably new bra which hasnít stretched), you need to stay with a 38 but try a C cup. Only go down to 36 if the band also too big. A 36D will give a tighter band and one size down in the cup


Emma Matthews

Hi Emma, from these measurements I would try a 30DD and then have a look at our bra fit guide if you need further help from that point on

My cup size was 38dd but now the back is tight so went for a 40dd and cup too big and back just rides up help please


Val
Tuesday, 13 February 2018  |  7:39

Hi Alison, are the 38DD and 40DD bras the same brand/range? Sizes can differ between brands and even styles, so you may not be comparing like with like. If the back is riding up on the 40DD this would definitely suggest that a 40 in this brand is too big. Were you wearing it on the tightest or loosest hook? Try the 40DD on the tightest hook, if this is a better fit, a 38 would be a better fit for you. If you feel that you need to stay with a 40 band, the comparable cup size from a 38DD would be 40D, not 40DD. This is why the cup is too big. Have a look at our fit guide for further help
