Bra Size Calculator
Do you hate bras, or are you just wearing the wrong size? According to research, 80% of women wear the wrong size bra. Imagine wearing shoes that are two sizes too big or too small! Sounds like a painful nightmare, right? Well, that’s exactly how your upper body feels when you leave your breasts hanging (or suffocated!) in a bra that’s the wrong size.
While there is no way to get the perfect size consultation at home, the bra measuring system comes pretty close! Not all bras are equal in fit (see our breast profile guide to learn why!) but, with a little measuring tape and effort, you can find your size in the comfort of your own home. A fact that is little known among our women is that, just because your bra fit you perfectly at age 16, doesn’t mean it will at 20! Things like losing or gaining weight, exercising, nursing and age can alter your bra size, making it necessary for you to refresh your bra wardrobe.
Well, let us help! Our online bra size calculator will make the process as simple as 1-2-3. Just put on a non-padded bra, grab a measuring tape and get ready to measure yourself! (Hint: And once you’re done, browse or have a look at our Losha Bra Styling Guide to help you choose what style works best for you.)
Bra Size Calculator
Find your estimated bra size using two simple measurements. Use a soft measuring tape and enter both measurements in centimetres.
For best results, measure while wearing a non-padded bra.
Step 1: Measure Your Underbust (Band Size)
Measure yourself wearing a contour or underwire bra (avoid padded or push up bras), Stand up, then relax your arms and shoulders. Breathe out. Wrap a tape measure around your chest and back, just under your breasts. It’s OK to hold it tightly – your bra is designed to stretch. Keep the tape parallel to the floor.
Step 2: Measure Your Overbust (Cup Size)
Next, take the tape and measure around your breasts and back. Again, keep the tape parallel to the floor. Let it rest gently against the fullest part of your bust. Don’t hold the tape too tightly this time. Again, enter your measurement below, in centimeters (cm).
