How We Compare Two Sizes
We look at three things: the raw band difference (how much the ribcage measurement differs), the cup letter difference, and the estimated volume difference since the same cup letter jump means very different things on a small band versus a large one. This is especially useful when you're deciding between your usual size and its sister size, or comparing an old size to a new post-pregnancy or post-weight-change estimate.
Frequently Asked Questions
Why compare volume instead of just the letters?
Cup letters aren't consistent across bands, so two sizes with the "same" letter gap can actually differ a lot in real volume.
Can I use this to decide between my old and new size?
Yes enter your pre- and post-change sizes to see exactly how much has shifted before you shop.
What if the comparison shows almost no difference?
That usually means the two sizes are close sister-size equivalents, and either should fit similarly.
