Frequently Asked Questions
Q: Why do I need to measure both standing and leaning?
A: Measuring both positions helps account for different breast shapes and provides a more accurate cup size calculation. Our calculator uses a weighted average (70% standing + 30% leaning) for optimal results.
Q: What are sister sizes?
A: Sister sizes are different bra sizes that hold the same cup volume. For example, 34C, 32D, and 36B are sister sizes. If one size doesn't fit perfectly, try the sister sizes.
Q: How accurate is this chart?
A: Our chart is based on international sizing standards, but bra sizes can vary between brands and styles. This chart provides a starting point, but we recommend trying on bras when possible.
