If you’re reading this, you probably know as well as any other woman that finding your bra size isn’t as easy as you once thought. Your bra size has likely changed throughout your life which can happen for a number of reasons including fluctuating weight and having children.
How to Measure Bra Size in 3 Steps
There’s much more to measuring your bra size than just grabbing a measuring tape and marking down a band size. In the next three steps, we’ll go into measuring your band size, then your bust size, and lastly, your cup size.
Determining the correct measurements for your band, bust, and cup size will make it easier for you to find bras that fit right no matter where you get your bras.
Step 1: Find Your Band Size
Make sure to wear a lightly-lined or unpadded bra before measuring your band size. Take a measuring tape wrap it snugly across your back, keep it parallel to the ground and measure directly under your bust. Round down to the nearest even number and note your band size.
Step 2: Measure Your Bust Size
Keep the measuring tape around your back at band level and measure across the fullest part of your chest, making sure to hold the measuring tape snugly against you and parallel to the ground. Do a few deep breaths to let the tape rest on its most comfortable position. If it falls on the half-inch, just round up.
Step 3: Determine Your Cup Size
Determining cup size is where things can get tricky because cup sizes can vary depending on the maker. The most common way to calculate your cup size is by subtracting your band size from your bust size and using the difference to find your cup size. For example, if your chest size (A) is 102cm / 40” (inches) and under the bust is (B) is 85cm/33” (inches) your A-B is 17 cm/7” (inches). This would mean you have a cup C.
Bands are measured tightly under bust, cups are measured loosely over the fullest part of the bust. If you are between two band sizes, choose the smaller. If you are between two cup sizes, choose the bigger.
