Bra Size Basics – Braducational Video

By Linda's Online on September 24th, 2013

Hi I’m Kim from Linda’s!  32A, 40D, 34DDD, 38B … We all recognize a bra size when we see it. But do you know what these numbers and letters actually mean? You’d be surprised how many women don’t know the basics of bra fitting – and you may even be one of them!

What does Band Size Mean?

The number portion of your bra size is your band size.  This number relates to your “underbust” – the spot right under your breasts where your bra band should lie.

The wider this part of your body, the higher your band size will be.

Bra band sizes are even numbers, usually between 28 and 56. (That’s right! At Linda’s, we carry a wide range of band sizes!)

Tip: Your band size has nothing to do with how large your breasts are. In modern bra sizes, your band size is typically about 0-3 inches larger than your ribcage measurement in inches. Remember, a snug bra band is very important for a good fit, because your bra band provides about 90% of your bra’s support!

What does Cup Size Mean?

The letter after your band size is your cup size. The cup size tells you the difference between the size of your breasts and the size of your rib cage.

At Linda’s we carry AA to N cup sizes. AA is the smallest, and N is the largest.

This brings me to a very important bra fitting tip: your cup size is relative to your band size.  As the band size gets bigger, the cup gets bigger too. For example, a 36B bra is about one cup size larger than a 34B bra, and two cup sizes larger than a 32B bra.

If you go down to a smaller band size, your cup size has to go up if you want the same amount of space in the cup. So a 36B bra has the same cup size as a 34C or 32D bra. This is often called a “sister size”.

With this in mind, don’t get too hung up on your cup size. Some women are shocked or upset when they find out they’re a AA or D or G cup. In reality, the cup size is almost meaningless without the band size.

Tip: Just like jeans, bra sizes vary in size from brand to brand, or country to country. For instance, UK brands use double letter cup sizes, like FF, or HH. And in some companies a DD is the same size as an E cup.

It can get confusing, and that’s why we’re here to help you navigate the world of bras and choose the perfect size and style, just for you.

Buy bras that help you look and feel great and don’t worry about the size on the tag.  At Linda’s, size doesn’t matter. It’s the fit that’s most important.

Don’t worry, you don’t have the be a bra fitting expert – that’s what we’re here for! For more information visit us at a Linda’s shop or visit online at Also, visit the Braducational Video page on our website, or check out more blog posts like this one!
