Biggest Bra Size: Most Common Questions

  • Lingerie Lowdown

Whether you’ve read my blog before, you’ve googled a specific question, or you’ve stumbled here by complete accident, you’re probably interested in the biggest bra size and all the questions that go with it. 

I recently wrote a blog post on Smallest Bra Size: Most Common Questions, so I thought it was only right to do another on the biggest bra size. You’re welcome!

What is the Biggest Bra Size?

Apparently, the biggest bra size ever recorded is 102ZZZ, which, to put it plainly, is absolutely crazy (that poor woman). However, the average biggest bra size is a bit smaller than that...

What is the Biggest Bra Cup Size?

The biggest bra cup size, or the most widely available one, is a K cup, but obviously it’s possible to be bigger than this. If you're measuring bigger than a K, it's most likely that you'll have to get your bras made by a specialist place.

What is the Biggest Bra Back Size?

The biggest bra back size is typically around the 52 inch mark. Again, though, it’s possible to be bigger than this. (If you're measuring higher than 102ZZZ, you will also need to alert Guinness World Records.)

How High Do Bra Sizes Go?

Cup sizes typically range from AA (the smallest) to a K (the biggest), and chest sizes range from 28-52 inches. If you find that your sizes are bigger than these, it's recommended that you go to a specialist lingerie store for further advice from a fitting expert.

Is a DDD the same as an F?

If you've been measured as a DDD, or you've found a bra in a DDD size, then it's important to know what this is the equivalent to. Most places don't count DDD as a real size, and it is actually the same as an F cup. If you need more help with bra size conversions, view our how to measure your bra size guide.

Biggest Bra Size: Finding the Right Bra

The bigger your boobs get, or the fuller your chest is, the harder it becomes to find a bra. This is down to a number of reasons. Not only is it to do with what is or isn’t available, it’s also because you need a certain level of support. 

Unfortunately, there’s a lot of cheap bras out there that aren’t designed with your support and comfort in mind, so many people end up in pain and discomfort from poor quality bras. Luckily, at BraForMe, we’re all about inclusivity, and we really understand the importance of a bra that protects and properly supports your breasts.

Our Top Pick For Larger Cups

Best K Cup Bra

If your boobs are on the larger side of the scale, you might have already heard of Elomi. If you haven’t, let me introduce you…

Elomi are part of the Wacoal group, and they’re well known for their supportive bras that go all the way up to a K cup. The  range is a great place to start. It features two full cup bras: Elomi Cate full cup bra and Elomi Cate Soft Cup. The Soft Cup bra actually starts from a B cup, so it’s suitable for all bra sizes with fuller shapes.

However, if we’re talking about the best bra for the biggest bra size, then we need to discuss the Underwired Full Cup Bra. Not only does this bra come in a stunning range of colours, but it’s packed with lots of great features designed to support you and keep you comfortable.

Elomi - Cate Full Cup Bra

  • Comes in sizes DD-K in multiple colourways

  • Has unpadded, smooth underwired cups for comfort without sacrificing support
  • Provides a natural rounded shape, uplift and separation

  • Features a stylish arc design

On the higher end of the price scale, we have PrimaDonna bras. PrimaDonna are known for producing unbeatably high-quality bras, with a luxurious look and feel. Although the price point might seem intimidating at first, they are completely worth the money.

PrimaDonna - Orlando Full Cup Bra
