What cup size is 90 cm? In the world of bra sizing, a 90 cm measurement typically refers to the band size, not the cup size. The cup size is determined by the difference between your bust and band measurements. To find the cup size, you need both the band measurement (90 cm) and the bust measurement.
Understanding Bra Sizes: How to Determine Your Cup Size
What Does 90 cm Mean in Bra Sizing?
In many European countries, especially those using the metric system, a 90 cm band size is common. This measurement corresponds to the circumference of your ribcage right below the bust. However, to determine the complete bra size, you also need the bust measurement, which is the fullest part of your chest.
How to Calculate Cup Size?
To find the cup size, subtract the band size from the bust measurement. The difference in centimeters will help you determine the cup size according to standard sizing charts.
- 1 cm difference: A cup
- 2 cm difference: B cup
- 3 cm difference: C cup
- 4 cm difference: D cup
- 5 cm difference: E cup
For example, if your bust measures 95 cm and your band size is 90 cm, the difference is 5 cm, indicating an E cup. Thus, your bra size would be 90E.
Why Accurate Measurements Matter
Wearing the correct bra size is crucial for comfort and support. An ill-fitting bra can lead to discomfort, poor posture, and even back pain. Accurate measurements ensure that the bra fits snugly, providing the necessary support without being too tight or too loose.

Tips for Measuring Bra Size at Home
- Use a Soft Measuring Tape: Measure around your ribcage, just under your bust, to get the band size.
- Measure the Bust: Wrap the tape around the fullest part of your chest.
- Calculate the Difference: Subtract the band measurement from the bust measurement to find your cup size.
- Check for Comfort: Ensure the bra feels comfortable and supportive without digging into your skin.

How Do I Know if My Bra Fits Correctly?
A well-fitting bra should sit level around your body without riding up at the back. The straps should be adjusted so they don’t dig into your shoulders, and the cups should fully encase your breasts without spilling over or gaping.
What Are Sister Sizes in Bras?
Sister sizes are alternative sizes where the cup volume remains the same even though the band size changes. For example, if a 90C is too tight, you might try a 95B or an 85D for a similar cup fit.
How Often Should I Get Measured for a Bra?
It’s recommended to get measured every six months to a year, as weight fluctuations, hormonal changes, and age can affect your bra size.
Can I Measure My Bra Size Without a Tape Measure?
Yes, you can use a piece of string to measure your band and bust, then measure the string with a ruler. However, using a soft measuring tape is more accurate.
Why Are Bra Sizes Different Across Brands?
Different brands may have slight variations in sizing due to design and material differences. It’s always best to try on a bra before purchasing or refer to the brand’s specific sizing chart.
