The Period Company Medium in every brand's language
By The Period Company's own published claim, its Medium tier holds 20 mL Data quality grade B, converted from tampon counts. Tier names don't transfer between brands - millilitres do. Here is the smallest tier in each other brand whose claimed capacity covers it.
The source claim
The Period Company Medium: 'Medium absorbency... Absorbs up to 4 tampons worth of flow!' (PDP verbatim, verified 2026-06-11)
The covering tier in each brand
“Covering” means the smallest tier whose claimed maximum meets the middle of The Period Company Medium's range (20 mL). Grades: A = brand publishes mL, B = converted from counts at a stated basis, C = conflicting or unconfirmed.

All figures are the brands' own maximum-capacity claims, normalized to millilitres - claims made comparable are still claims, not lab measurements (the only blood-component study, BMJ Sexual & Reproductive Health 2023, measured far lower effective capacity than marketing figures). Sources, conversion rules, and verification dates live in the methodology.
