If you’re like most women, you’ve had a few questions about bras. What size should I buy? Will a certain style or brand fit better? How do I find the right fit? (skip straight to the Underwire Bras Size Chart)

Bras are sized in letters, numbers, and cup sizes. 

The letters represent the band size, while the numbers represent the cup size. For example, a 34B bra has a band size of 34 and a cup size of B. 

In addition to standard cup sizes (A-D), some bras feature cup sizes DD and up (known as D2+, D3+, etc). These bras are designed for women with larger breasts who need extra support and coverage. 

We’ll now proceed to look at aspects of measurement and the ar9us charts that you can rely on depending on what type of underwire bra you are keen to buy.

The first step is to measure your band size:

1. Place the measuring tape around your ribcage, under your breasts. Right where the band of your bra would go when you put the bra on. Pretend as if the tape was your bra band. 

3. Make sure it is pulled tight but is not uncomfortable and that the tape is level.

4. Note how many inches you are and add 3 to this measurement. For example, if your ribcage is 31 inches, your band size is 34. If you land on an even number this is your band size.

5. If you land on an odd number, you’ll want to round up or round down to the nearest even number based on your build. Round down if you’re softer (more “plum”) around the band and round up if you’re leaner (more “bony”) and don’t have much give around the band. This is your band size.

The next step is to measure your cup size:

1. Place the measuring tape around the fullest part of your bust. This is usually over your nipples or the “roundest” part of your breasts. You won’t need to pull the tape particularly tight for this measurement it just needs to sit flat, but you’ll still want to ensure it’s level. 

2. Make a note of how many inches you are. This will help determine your cup size.

3. Check the chart above and pick the range you best fall in.

What if Your Measurements Are in Between Sizes?

If your measurements are in between sizes, we recommend ordering the smaller size. This will ensure a better fit and provide the most support. You can still size up if your instincts tell you this is the perfect solution for you. A size up will mean that your bra will fit not so tightly while a size down would most likely feel a little tight. 

Different uses for different underwire bras size charts 

Underwire bras size charts typically list the bra sizes in alphabetical order with the corresponding cup size. But they are not uniform, as they might vary based on different factors as we have already seen. 

For example, if you’re under the age of 30, you would use the A-D cup size range. If you’re over the age of 30, you would use the DD-F cup size range. 

Underwire bras size charts can also be used based on bathing suits (underwire bra size chart bathing suits) or babies (underwire bras size chart baby). 

Lastly, you can use an underwire bras size chart by height (underwire bras size chart by height). This method considers your body height and determines the best fitting bra size for you.

Frequently Asked Questions

How do I know what size underwire I need?

Your best bet is to use an underwire bra size chart, which you can use in combination with an underwire comparison chart (underwire bras size chart comparison ) and conversion. An underwire bras size chart is best if you know your current size and want to see what other sizes are available. The underwire conversion chart (underwire bras size chart conversion) is best if you know your bra size in inches or centimeters and want to find the equivalent size in a company’s range of underwire bras. 

How is an underwire bra supposed to fit?

Underwire bras should fit comfortably and securely. The wire should sit flat against your ribcage and should never dig into your skin. The band should be snug (but not too tight) and should never ride up your back. The cups should fully cover your breasts and the straps should be adjusted so that they’re not too tight or too loose. 

What is the largest underwire bra?

The largest underwire bra size is about 46K. Some other large bra sizes include 44L, 45J, and 46H. Bras in these sizes are often difficult to find in stores, so many women have to order them online. 

The first thing you’ll want to do is measure your bust size. Once you have your measurements, you can use them to find your size on the chart. Keep in mind that the largest size may not always be available, so you may have to try a few different sizes before finding the perfect fit. 

Is there an underwire bra for plus size?

Yes! While there are not as many plus-size underwire bras as there are regular-size bras, there are still a few great options that cater to women looking for plus-size underwire bras.
