This page regularly updated and is best viewed in ‘desktop mode’ because of the tables & photo comparison tools. If you are on mobile, you can easily toggle to desktop view at the bottom of this page (click here).
The chart featured here is a metric version of my original chart. If you need more guidance than simple measurements, please check out the blog post featuring my original Menstrual Cup Comparison Chart for tips on how to choose the right cup for your body.
The table below is a size comparison for several brands of cups, the first set are brands that I have personally used (testing does not equal endorsement). The cups below are all made from silicone, with the exception of the Keeper (Rubber) and Me Luna cups (TPE). These cups range in price from about $20 – $40 – and they are well worth it!
For more information about the firmness score, please visit the Menstrual Cup Firmness Guide from Put A Cup In It.
