Thinx Super (legacy ladder) in every brand's language
By Thinx's own published claim, its Super (legacy ladder) tier holds 45 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
Thinx Super (legacy ladder): up to 5 regular tampons (legacy ladder, see Light)
Note: Thinx no longer uses this tier in its current product marketing - this page translates it for shoppers who still own or remember it.
The covering tier in each brand
“Covering” means the smallest tier whose claimed maximum meets the middle of Thinx Super (legacy ladder)'s range (45 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.
