I suppose that'd depend on how tight the sports bra is and how squishable your breast tissue is. I have a size M and my chest wraparound goes from 93cm to 84cm -- I'm a somewhat serious swimmer though so my chest and back muscles are bigger than average (best description I can come up with is that invisible unflexed but visible flexed). A good comparaison would be that the binder compresses roughly as much as pressing on my chest with both hands interlinked as much as possible. Hope this makes and is useful! Happy to answer further questions
