How to Know Your Bra Size: A Guide to the Perfect Fit

Finding the perfect bra size is essential for comfort, support, and confidence. An ill-fitting bra can cause discomfort, poor posture, and even long-term health issues. Many women wear the wrong size without realizing it, but with the right measuring techniques, you can determine your true bra size and enjoy a flawless fit.

Step-by-Step Guide to Measuring Your Bra Size

To accurately measure your bra size at home, you’ll need a soft measuring tape, a mirror, and a non-padded bra for the most precise results.

1. Measure Your Band Size

The band provides the primary support for your bra, so getting this measurement right is crucial.

• Wrap the measuring tape around your ribcage, just under your bust.

• Keep the tape snug but not too tight.

• Round to the nearest whole number.

• If the number is even, add 4 inches; if it’s odd, add 5 inches. The total is your band size.

For example, if your ribcage measures 32 inches, adding 4 inches gives you a band size of 36.

2. Measure Your Bust Size

• Place the measuring tape around the fullest part of your bust.

• Ensure the tape is level and not pressing into your breasts.

• Round to the nearest whole number.

3. Calculate Your Cup Size

• Subtract your band size from your bust measurement.

• The difference determines your cup size:

  • 1-inch difference = A cup

  • 2-inch difference = B cup

  • 3-inch difference = C cup

  • 4-inch difference = D cup

  • 5-inch difference = DD (or E) cup

For example, if your bust measures 38 inches and your band size is 36, the difference is 2 inches, which means you have a B cup.

Signs You’re Wearing the Wrong Bra Size

Even after measuring, it’s essential to check the fit of your bra. Here are some common indicators of a poor fit:

• Straps Digging In or Slipping Off: If your straps are too tight or constantly slipping, your band or cup size may be incorrect.

• Band Riding Up: Your band should sit level across your back. If it rides up, you may need a smaller band size.

• Cup Spillage or Gaping: If your breasts overflow from the cups, the size is too small. If there’s gaping, you may need a smaller cup size or a different bra style.

• Uncomfortable Underwire: If the underwire digs into your skin or sits on top of your breasts, your cup size may be too small.

Bra Fit Tips for Different Breast Shapes

Different breast shapes require different bra styles for the best fit and support.

• Full on Top: Opt for balconette or full-coverage bras to prevent spillage.

• Full on Bottom: A demi-cup or push-up bra can enhance the upper bust.

• Asymmetrical: Choose bras with removable padding to balance the shape.

• Wide-Set Breasts: Look for plunge or front-closure bras to bring the bust closer together.

Why Professional Bra Fittings Matter

While measuring at home is a great starting point, professional bra fittings can provide the most accurate results. Lingerie specialists can assess your size, breast shape, and preferred style to recommend the perfect fit.
