Bra Cup Sizes (Smallest to Biggest)
Which is the smallest bra cup? What about the largest cup? In this guide, we present bra cup sizes (from the smallest to the biggest).
Do you know the smallest and biggest bra cup sizes?
Well, the answer to this question really depends on the bra manufacturer. Not all manufacturers make bras of all sizes. In fact, there are only a few manufacturers that make bras for full figured women.
Small Cup Sizes
Generally, the smallest bra cup size available in most stores is an AA.
An AA cup measurement means the difference between the size of the fullest part of the breast and the underbust is less than one inch.
To find your bra cup size, you need to measure your underbust and overbust, and then get the difference between them.
Here is a video showing how to measure your breast size:
If you have a small chest, you won’t really need an underwire bra as your breasts are not likely to be too heavy to require support. Therefore, you can easily find both bras and bralettes for your size!
Large Cup Sizes
There is no limit to how large a bra can get. However, the design usually has to be modified for full figured women. The customization can end up being quite expensive.
In most stores, you will find bras going up to an F cup. A couple of stores will even go up to a K cup and beyond.
The bra cup size depends on the measurement of the underbust (under-band) and overbust (the measurement of your bust passing through the nipples). The cup is determined by the difference between the two measurements.
However, keep in mind that bra measurements are not standardized. Therefore, you should always check the size guide provided by a company.
Bra Cup Sizes
The bra cup size is determined by the manufacturer. Some manufacturers offer a variety of bras from size 32, while other start their sizing from 28.
Generally, Asian bra manufacturers start their sizing from 32 while brands from Europe start from 28.
With that said, let’s look at all the bra cup sizes, from smallest to largest.

Now that you know bra cup sizes, what is your actual cup size?
If you have already measured your overbust and underbust and found the difference between the two, refer to the following table for your actual cup size.

So, your cup size is the bust size measurement and the corresponding alphabet denoting the difference between the overbust and underbust measurement.
For example, if your underbust is 40inches and your overbust is 44inches, the difference between the measurements is 4 inches. Therefore, you are a 44D.
