Description

PeriodFinder puts every brand's published sizing and absorbency claims on one scale, so they can actually be compared. Absorbency is translated into millilitres and graded by how well each brand documents its number. Sizing is translated from a single hip measurement into each brand's own size, with notes where a brand runs small or large. Ask which Knix tier matches Thinx Super, what size fits a 40 inch hip in every brand, or which in-stock products cover a given absorbency. Answers come from a catalog of 468 products across nine brands, refreshed weekly, with the method published openly at periodfinder.com/absorbency/methodology. PeriodFinder is an independent comparison site. It is not medical advice, it does not diagnose anything, and it takes no payment from any brand for placement or ranking.
