3 Easy Steps on How to Find Your Bra Size at Home


We all know the struggle of an ill-fitting bra. The gaping, sagging, pulling, double boob—the list goes on. If you’ve ever been there, you’re not alone. Luckily, there’s an easy solution to ensure you look and feel great in the bras you’re wearing. You can measure your bra size in the comport of your home.

It’s as simple as knowing your correct bra size. By doing so, your clothes will fit better and you’ll feel more comfortable. You can also shop online and feel confident choosing your perfect size without staring at a bra sizing chart and scratching your head in confusion. That’s a win-win-win in our book.

We don’t always have time to go out and get a professional bra-fitting so one of our bra fit experts, Janelle, shared a quick and easy guide for how to measure your bra size at home.

Why is it Important to Have a Well-fitting Bra?

Before we jump into the step-by-step guide for how to measure bra sizes at home, let’s chat about why it’s so important to have a bra that fits well. As women, our bodies can change often and as much as a full cup size within one month’s time. We have reasons like hormones, weight fluctuations, and breastfeeding to thank—just to name a few.

With all that said, it’s important to measure yourself regularly. In an ideal world we’d all get professional bra-fittings done multiple times throughout the year. We understand that life can get in the way of that. As a go-to back-up plan, you can break out the measuring tape and measure yourself at any moment you think your bra size has changed.

Find Your Bra Size in 3 Easy Steps

Step 1: Grab a Measuring Tape and Your Cell Phone

The very first step for conducting your at-home bra fitting is to gather all needed supplies. Be sure to grab your smart phone and download our Soma® app. Through our app, you’ll have access to the easy-to-use bra size calculator where you’ll input your measurements along the way. Finally, put on a non-padded bra, grab your soft measuring tape, and stand in front of a mirror.

P.S. To locate the calculator in the Soma® app, make sure you’re logged in, go to the Account tab, tap Bra Fit Guide, and you’re ready to begin.

Step 2: Measure Your Band Size

As you click into the app, it’ll prompt you to input each bra measurement starting with your bra band size. Your band measurement is the circumference around your torso, directly under your bust. Janelle suggests you pull the end of the tape to the side to avoid going over the stomach and ensuring it is nice and snug. A good rule of thumb is to always round up to the nearest half inch. Now you can input your measurement into the app.

Step 3: Measure Your Cup Size

The final step for how to measure your bra size is to identify your cup size. Slide the tape up to the middle of your bust (around nipple level) and measure all the way across. Again, you’ll want to round to the nearest half inch.

Once you input your cup size, your bra size will be automatically calculated in the app—no math required on your end. Now you’re free to shop for your next favorite bra like one from our Bodify collection. Did you know that it’s the bra that changes with you? In fact, it has special cups that stretch and recover to each boob, a wire in airflow mesh that moves with you, and straps that don’t slip. It’s our solution to many common bra problems.

How Often Should You Get Measured for a Bra?

Now that you’ve found your custom bra size, you might be wondering how often you should get measured for a bra. The answer is simple—you should get a regular bra fitting at least every six months to a year. You can take your bra measurements as often as you’d like at home, but we highly encourage you to check in with a professional from time to time. With that said, we welcome and encourage you to come into your nearest Soma® store to get fitted by one of our experts. We’d love to have you in.
