Why Is It Important to Measure Bra Sizes Correctly?

Wearing the wrong bra sizes can lead to discomfort, poor posture, and even long-term health issues. Accurate measurements ensure you get a bra that fits properly, supports you well and boosts your confidence.

Measuring Bra Sizes

The bra size calculator in India uses two primary measurements: the underbust (the band size) and the overbust (the cup size). Follow these steps to find your perfect fit:

Step 1: Measure the Underbust

  • Use a soft measuring tape and wrap it snugly around your ribcage, just under your breasts.
  • Ensure the tape is level and straight.
  • Note the measurement in centimetres or inches. This is your underbust measurement.

Step 2: Measure the Overbust

  • Wrap the tape around the fullest part of your bust (over the nipples).
  • Make sure the tape is not too tight and remains level.
  • Record this as your overbust measurement.

Step 3: Calculate the Bra Size

  • Band Size: Round your underbust measurement to the nearest even number. For example, if your underbust measures 31 inches, your band size is 32.
  • Cup Size: Subtract the underbust measurement from the overbust measurement. Use the difference to determine your bra cup size using a standard bra size chart:
Difference (in inches) Cup Size
1 A
2 B
3 C
4 D

Examples of Bra Size Calculation

Example 1:

  • Underbust: 30 inches
  • Overbust: 32 inches

  • Result: 30B

Example 2:

  • Underbust: 32 inches
  • Overbust: 35 inches
  • Band Size: 32
  • Difference: 35 – 32 = 3 (Cup Size: C)
  • Result: 32C
