Bra Size Calculator

Finding your bra size used to take time and effort. Let us do the work for you!

How To Measure Bra Size

To find your bra size, you'll need a tape measure and your best-fitting bra. (If you don't have a flexible tape measure, use a string and then measure it.)

1. Measure your band size

Wearing your bra (no sports bras or minimizers, please), take a snug measurement around your ribcage in inches, directly under your bust and level all around. If you get an odd number, round up to the next whole number (or our calculator will round up for you).

2. Measure your bust size

Take a loose measurement over the fullest part of your bust in inches, keeping the tape level around your body. If needed, round up to the nearest inch (or our calculator will round up for you).

3. Calculate your bra size

Subtract your band size from your bust size. You can then find your cup size using the Bra Size Chart below.

Converting Bra Sizes

A bra made by a US brand is sized differently than one from Europe or the UK, so anything above a D-cup may need to be converted. When you’re looking at bras on our site, we’ll let you know if you need to convert your size in the Fit Note under Product Details, or use the pop-up Convert My Size tool and let us do the work for you!

A Word About Bra Sizing

We get that bra size can be confusing, so think of it like jeans shopping. You don’t always wear the same size pants, and you would never assume a pair fits without trying it on first. The same is true for bras! Just as getting the perfect fit in denim depends on the brand, cut, style and rise, one bra might be great on you; another, not so much.

GET THE PERFECT FIT




How will you know when you’ve found the perfect fit?

Like falling in love, when it happens, you’ll know. Your breasts will be where you want them to be and look how you want them to look. You should feel lifted and supported, with zero pain. You know how when something doesn’t feel quite right, it’s all you can think about? This is the opposite of that. When the fit is fab, you won’t think about your bra at all. You’ll be contained, comfortable, confident and in control of your day. The perfect fit frees you up to handle anything; it lets you do you.

That’s why we never want you to settle for “good enough” again. Every time you put on a bra, check for the Fit 5, our favorite way of gauging whether it’s the best fit for you.

How to Measure Bra Size: 5 steps to a better fitting bra


Why You Should Have a Professional Bra Fitting

Our certified bra fit experts can measure and fit you, by phone or chat. Because our bodies are constantly changing, we recommend getting fitted every six months. We often find women are wearing too big of a band size and too small of a cup size. Our trained experts know how to quickly and easily get you into a better bra.

10 THINGS OUR BRA FIT EXPERTS
WISH YOU KNEW





  1. Wearing the right bra makes all the difference in how your clothes fit, how you feel, how your day goes. That’s why we are for everybody—and every body. The range we carry—76 unique sizes in bands 28 to 58 and cups AA to O—is unrivaled. We’re here to pair you with the perfect bras.

  2. Even with all the right measurements, you still have to try on a bra for fit.

  3. Stop paying attention to the letter and the number. You’re so much more than your bra size. Fit and support are what matter most.

  4. Start paying attention to which styles flatter your figure—bra types are so much more than a personal preference. Plunge bras are ideal for petites and close-set chests. Balconettes work for broader shoulders and full busts. Three- or four-part cups help center wide-set breasts. Smoothers banish back fat without sacrificing support.

  5. After 20 years in the business, we’ve found the best brands for petites are Chantelle, Natori, OnGossamer, Calvin Klein and DKNY. For average sizes, your best bets are Wacoal, Natori, Chantelle and Simone Pérèle. Full busts will love Freya, Panache, Fantasie, Prima Donna and Empreinte. Curvy figures, check out Elomi, Goddess, Glamorise, Bramour and Curvy Couture.

  6. If you rip your bra off the minute you walk in the door, it’s time for an intervention. The right bra should never be painful or even annoying to wear. It exists, and we can help you find it.

  7. The ideal wardrobe is made up of six bras: two nude and two black in styles that suit you, one strapless and one sports bra. Anything above and beyond is a bonus. For travel, pack two regular bras, a bralette, a sports bra if needed, a swimsuit and a pair of underwear per day plus two extras.

  8. Use a drawer to store your bras—nest them together, with cups splayed out lengthwise—and stash underwear and socks separately. Keep lingerie in a delicates bag to prevent snags, rips and fading.

  9. Hand-wash, or machine-launder in a mesh bag with a detergent made for delicates. Always air dry.

  10. Replace bras every six months (or sooner after weight loss, weight gain, pregnancy or weaning).
