Finding the right bra size can be a game-changer for your comfort and confidence.  Wearing a bra that fits well can enhance your posture, alleviate back pain, and make your clothes look great.  Here is a comprehensive guide to help you measure your bra size accurately at home.

Why Correct Bra Sizing Matters

A bra that fits properly offers you the support you need and stops you from being uncomfortable.  Wearing the wrong size can lead to issues like:

  • Back, shoulder, and neck pain
  • Breast spillage or gaping cups
  • Straps digging into your shoulders
  • Bands riding up your back

 What You'll Need

  • A soft measuring tape
  • A mirror
  • A pen and paper to note down measurements
  • A well-fitting, non-padded bra (optional but it helps with accuracy)

Step By Step Measuring Guide

1. Measure Your Band Size

Step 1: Stand in front of the mirror and wrap the measuring tape snugly around your ribcage, directly under your bust.  Make sure the tape is level all the way around.

Step 2: Note the measurement in either inches or centimetres.  This is your band size.  Make a note of this measurement.

Tip: The tape should be tight but not uncomfortable.  Make sure it is parallel to the ground and lies flat against your body.

 

2. Measure Your Bust

Step 1: With the measuring tape, measure around the fullest part of your bust.  Make sure the tape is straight and not too tight.

Step 2: Not this measurement down.  It's helpful to take this measurement while wearing a non-padded bra to get an accurate number.

Tip: Stand naturally without arching your back or slumping to get the most accurate measurement.

4. Calculate Your Cup Size

If you wish, you can calculate your cup size by subtracting your band size from your bust measurement.  The difference in inches or centimetres corresponds with your cup size:

  • A cup = 1 inch / 2.5 cm
  • B cup = 2 inches / 5 cm
  • C cup = 3 inches / 7.5 cm
  • D cup = 4 inches / 10 cm
  • DD/E cup = 5 inches / 12.5 cm
  • DDD/F cup = 6 inches / 15 cm and so on.

For example, if your band size is 34 inches / 86 cm and your bust measurement is 37 inches / 94 cm, the difference is 3 inches / 8 cm, making you a 34C.

Common Fit Issues and Solutions

  1. Band riding up: Your bra is too loose if the band rides up your back.  Try a smaller band size. 
  2. Straps digging in: If your bra straps dig into your shoulders the band might be too loose, or the cup size might be too small.  Make sure the band provides most of the support.
  3. Spillage or gaping: You may need to change your cup size if your breasts spill over the cup or there is gaping.  For spillage, try a larger cup and for gaping, try a smaller cup.
  4. Centre panel not laying flat: The centre panel of the bra should lie flat against your chest.  If it doesn't, the cup size might be too small.

Tips For The Perfect Fit

  • Adjust straps: Straps should be snug but not tight.  Adjust them as needed.
  • Test the band fit: You should be able to fit two fingers comfortably under the band.  It should feel snug but not constricting.
  • Scoop and swoop: When putting on your bra, lean forward, scoop your breasts into the cup and adjust the band and straps.

When To Re-measure

Your body can change due to weight fluctuations, pregnancy or hormonal changes so it's a good idea to measure your bra size regularly.
