How Modibodi and WUKA period underwear compare on the only thing that travels across brands - capacity in millilitres - plus how each one's sizing runs. No brand's thumb on the scale.
Verified against the brands' own pages 2026-06-11 · Every capacity is the brand's own claim, graded and dated
By their own published claims, WUKA reaches a higher maximum capacity (up to 60 mL) than Modibodi (up to 50 mL) at its highest current tier. That does not make every WUKA pair more absorbent than every Modibodi pair - it means the top of WUKA's range is higher. Compare tier by tier in millilitres, not by the label words.
Every capacity above is the brand's own maximum claim, typically from a saline saturation test. The only published study with real blood components (BMJ Sexual & Reproductive Health, 2023) poured blood slowly onto three pairs of one unnamed brand's super-absorbency underwear until it pooled: under 3 mL each, 2 mL on average. That is a different measurement, not a ranking of these claims. Use the numbers to compare the two brands like for like, not as a leak-free guarantee.

The 3 in-stock pairs from each brand with the highest verified capacity claim, from the live catalog, highest first. Where a brand publishes no per-product capacity we can verify (Ruby Love pulled its claims), its 3 cheapest in-stock pairs instead, and the cards say so by showing no millilitre figure. Prices and stock are from the weekly refresh; a brand with nothing in stock shows no cards.
Sizing
Modibodi publishes no runs-small or runs-large guidance (order your usual size by hip); WUKA publishes no runs-small or runs-large guidance (order your usual size by hip). Both brands size from your hip measurement, so rather than converting one brand's size into the other's, the size finder gives you your size in each directly.
Modibodi: Modibodi publishes no runs-small or runs-large guidance. Its size guide says measurements refer to your body, not the product, and that hip is the measurement that matters most.
WUKA: WUKA publishes no runs-small or runs-large statement. It says to choose your usual dress size, then fine-tune by hip measured at the fullest part. Its Stretch pair covers up to four sizes for days when your size changes.
Quick answers
Is Modibodi or WUKA more absorbent?
By their own published claims, WUKA reaches a higher maximum capacity (up to 60 mL) than Modibodi (up to 50 mL) at its highest current tier. That does not make every WUKA pair more absorbent than every Modibodi pair - it means the top of WUKA's range is higher. Compare tier by tier in millilitres, not by the label words. These are saline-lab maximums, not leak-free guarantees; the one test with real blood (BMJ 2023, three pairs of one brand) measured a few millilitres before pooling, a different measurement from a claimed maximum.
Do Modibodi and WUKA use the same absorbency labels?
No. Modibodi publishes 3 current tiers (20–50 mL across the range) and WUKA publishes 4 current tiers (7–60 mL across the range). Even where the words overlap, the millilitres differ, which is exactly why this page compares them in millilitres with a data-quality grade on every number.
How do Modibodi and WUKA sizes compare?
Modibodi publishes no runs-small or runs-large guidance (order your usual size by hip); WUKA publishes no runs-small or runs-large guidance (order your usual size by hip). Both size from your hip measurement, so the size finder gives your size in each brand directly rather than guessing from the other brand's number.
Is Modibodi or WUKA better?
Neither is better across the board - they differ on measurable things. Compare three numbers on this page: the millilitres at the tier you actually need (not the tier names), how each brand's sizing runs for your hip measurement, and current prices in the catalog. The right brand is the one whose numbers fit your flow and your body, and that answer differs by person.
