How to Determine Your Correct Bra Size

My bra doesn't fit right! How can I measure for the right size?

With 80% of women wearing the wrong bra size, it’s a pertinent question to ask yourself: “Am I?” Well, ladies, you are not alone. I myself have struggled with finding my perfect bra size, especially after I lost 25 pounds. It took me about two years to figure out my size, and I have only recently been wearing the correct one.

Why is finding the right bra size so challenging? Weight fluctuations are a huge factor in determining your size. Of course, pregnancy (before, after, and during) is another variable to consider.

Plus, your correct bra size hardly ever fits into a single number (band size) and letter (cup size). For example, a DD cup is the equivalent of an E cup, and a DDD cup is the equivalent of an F cup. Manufacturers can’t seem to agree on a basic cup size system!

Some women wear even have 3 different sizes in their lingerie drawer, depending on what brands they’re wearing. Of course, the bra makers seem to love making it more difficult than it already is with different sizing and cup labeling. But not to worry. I have some great tips and tricks for how to find your perfect bra size. And believe me, I wish I had some of this knowledge two years ago.

First Measure for Band Size.

The first thing that you need to do to determine your bra size is to put on your lightly lined or unpadded bra. Then, measure directly underneath your breasts. Do this by using your measuring tape and wrapping it securely around your back. As you measure, make sure that the tape is level all the way around, with both sides of the measuring tape meeting in the front to determine your band measurement.

Once you have your correct measurement, round to the nearest whole number and make a note of it. If your number is odd, add 1, and if your number is even, add 2. That’s your band size! For example, if you measured 34”, add 2” to make 36”, which would be your band size.

Measure for Cup Size Next

Now it’s time to determine your cup size. Measure the fullest part of your bust, keeping the measuring tape lined up and level along your back, with the two ends of the tape meeting in the front again. Take a note of your bust measurement, rounding to the nearest whole number, and then subtract your band size from your bust measurement.

Remember that 36” band size I mentioned? Well, let’s say that the bust measurement was 40”. Now we can subtract the 36” band size from the 40” measurement of the bust, which comes out to be 4”. Using the chart below, we can determine that our example’s bra size is 36D.

See? Not as complicated as you thought it would be, right?
