How to Measure Yourself for a Bra – Braducational Video

By Linda's Online on May 17th, 2013

Hi everyone! It’s Kim from Linda’s 🙂 I hope you loved the first Braducational video: How to Hand Wash Your Bras. If you missed it, check it out! Next up in this series is: How to Measure Yourself for a Bra. Let’s be clear: an in-person fitting with an expert bra fitter (like the Bra Divas at Linda’s) is ideal. As expert fitters, we have so much bra knowledge in our heads, and have tried each of the of bra styles on hundreds of women. We typically use a measuring tape to measure a woman’s underbust, then take a look at her breast tissue for shape and size, and go from there. Getting a bra fitting at Linda’s is really easy, and fun. But if you can’t make it into the shop this video will walk you through the process of measuring yourself at home so you can find a starting point for your best bra size! Take a look at the video, and read my extra tips and advice below.

To measure yourself for a bra, you will need:

  • Your best fitting bra (Even if your current bra doesn’t fit perfectly, it’s better than no bra at all. The goal is to get your bust lifted so that you can get an idea of your current size. Avoid minimizers or push up bras.)

  • A soft measuring tape (You can pick up one of these at the drug store. They’re very inexpensive!)

  • Linda’s Online Bra Calculator (The calculator on Linda’s Online is a step up from the typical DIY subtracting method. The calculator uses a complicated algorithm to determine a starting point for your size.)

Step 1: Measure your underbust

With your bra on, use the soft measuring tape to measure underneath your breasts around your body. Really get that measuring tape directly underneath your bust! The measuring tape should be straight across, and parallel with the floor. Be sure to keep it taut. Remember, the bra band provides 90% of your bra’s support, and needs to be snug to do so – so make sure you’re relaxed (not holding your breath) and the tape is snug. In this case, our model’s underbust measurement is 29 inches

Tip: Even if your current bra doesn’t fit very well, it’s better than no bra at all. The bra should help lift your bust up enough so you can really get the measuring tape up in there, but if you need a buddy to help keep your bust lifted while you do this (hey, what are friends for?), don’t be afraid to ask.

Step 2: Measure your cup size

Again, with your bra on, use the measuring tape to measure around the fullest part of your bust. The tape should stay straight across from front to back. In this case our model’s cup size measurement is 36 inches.

Tip: Again, wear your best fitting bra while you measure your cup size. Even if it doesn’t fit perfectly, it will give a more accurate measurement than going braless. If your bra is particularly loose, worn out, or you have very large, sagging breasts, you can use the buddy system again. Have a friend use the bra straps to physically pull your bra up so that your breasts and nipple are about half way between your shoulder and elbow. Then measure around the fullest part of your bust. Not exactly ideal, but it has helped in certain cases.

Step 3: Calculate your size

Log on to and visit the Bra Calculator page. Use the fields to input your underbust and cup size measurements and click the “Calculator Your Size” button. In this case, the model’s measurements were 29 inches for her underbust and 36 inches for her cup size. The calculated size is a 30G.

Note: You’ll notice that the calculator will add between 0 and 3 inches to your underbust. Totally normal! All women of any size need a snug band for their bra to do its job, but basically, the fuller the bust, the snugger the band needs to be to stay in place. 

Don’t be alarmed if this is really different than the bra size you typically wear. Many women are not wearing the right bra size! (Read a little bit about bra sizes and why they may shock you.) And keep in mind, a calculator is a great tool, but it can never replace the expertise and insight of a real, expert bra fitter. A fitter can take into consideration your shape, body type, and different bra styles. Also, bras are similar to jeans: every brand and style fits a little differently. You’ll never get a true “this is my size in every bra” size from the calculator or a fitter. So use this size as your starting point. It’s a great step in the right direction, and with a little trial and error, you too can find the right bra and feel fabulous!
