Frequently Asked Questions

What does bra size mean?

Bra size includes two parts: the band size (number) and the cup size (letter). The band size measures around your ribcage, and the cup size represents the difference between bust and band.

How accurate is this bra size converter?

Our converter uses internationally recognized sizing charts and conversion standards. However, sizing can vary between brands, so we always recommend trying before buying when possible.

What are sister sizes?

Sister sizes are bra sizes that have the same cup volume but different band sizes. For example, 34C and 36B have the same cup volume, but 36B has a looser band.

Should I measure myself before using the converter?

Yes! For the most accurate results, measure your band size (around your ribcage under bust) and bust size (around the fullest part of your bust) before converting.

Do all brands use the same sizing?

No, sizing can vary between brands and manufacturers. This converter provides standard conversions, but always check the specific brand’s size chart when shopping.

Can I use this converter for sports bras?

Standard bra sizing applies, but many sports bras use S/M/L sizing. Check the brand’s conversion chart to match your size to their S/M/L system.

Why does my bra size differ in different countries?

Different countries use different measurement systems and sizing standards. For example, the US uses inches while Europe uses centimeters, leading to different size numbers even for the same actual measurements.
