What size is 100 in a bra? The number "100" in a bra size typically refers to the band measurement in centimeters. This size is commonly used in European and Asian countries. To find the corresponding size in other systems, such as the U.S. or U.K., it’s important to understand how bra sizing works and how to convert these measurements.
Understanding Bra Sizing
Bra sizes consist of a band size and a cup size. The band size is the number part of the size (e.g., 100), which measures the circumference of the ribcage just under the bust. The cup size is represented by letters (e.g., A, B, C) and indicates the volume of the breast.
How to Measure Bra Size
- Measure the Band Size: Use a soft measuring tape to measure around your ribcage, just under your bust. Keep the tape snug and level.
- Measure the Bust Size: Measure around the fullest part of your bust, ensuring the tape is level and not too tight.
- Calculate the Cup Size: Subtract the band size from the bust size. Each inch of difference corresponds to a cup size (e.g., 1 inch = A, 2 inches = B).
Conversion of Bra Sizes
To convert a size 100 band from the European system to U.S. or U.K. sizes, you can use the following table:
| Feature | European (EU) | U.S. (US) | U.K. (UK) |
|---|---|---|---|
| Band Size | 100 | 44 | 44 |
| Cup Size (example) | D | D | D |
Note: The cup size letter may vary slightly between countries due to different sizing standards.
Why Accurate Bra Sizing Matters
Wearing the correct bra size is crucial for comfort, support, and appearance. A well-fitted bra can improve posture, reduce back pain, and enhance the overall look of your clothing. Conversely, an ill-fitting bra can lead to discomfort and health issues.
Signs of a Poorly Fitting Bra
- Band Rides Up: If the band rides up your back, the band size might be too large.
- Straps Dig In: If straps leave marks or dig into your shoulders, they may be carrying too much weight, indicating a band that’s too loose.
- Cup Spillage: If breasts spill over the top or sides, the cup size may be too small.
- Wrinkling Cups: If the cups wrinkle or gap, the cup size may be too large.
