Understanding Bra Measurements

The Basics of Bra Sizing

Bra sizing is determined by two key measurements:

• Band Size: The circumference of your ribcage, measured just below the bust.
• Cup Size: The difference between your bust measurement and band size.

Both these measurements are essential for identifying your bra size.

Why Use Centimeters for Bra Measurements?

Many countries, such as Europe and Asia, use centimeters for bra sizing. Using cm ensures a more precise measurement and eliminates confusion when converting from inches. A cm-based calculator can save time and improve accuracy.

Step-by-Step Guide to Calculate Cup Size

Step 1: Measure Your Band Size

1. Take a soft measuring tape and wrap it snugly around your ribcage, directly under your bust.
2. Ensure the tape is level all around your body.
3. Record the measurement in centimeters.

Pro Tip: If the number is not whole, round it to the nearest cm for ease.

Step 2: Measure Your Bust Size

1. Wrap the measuring tape around the fullest part of your bust.
2. Keep the tape level and not too tight or loose.
3. Note the measurement in centimeters.

Step 3: Calculate the Difference

Subtract your band size from your bust size to find the difference:

Difference (cm) = Bust Size (cm)−Band Size (cm)

Step 4: Use a Sizing Chart

Compare the difference to a standard sizing chart to determine your cup size:

Example: If your bust size is 90 cm and your band size is 80 cm, the difference is 10 cm. According to the chart, your cup size is A.
