Absorbency
271 fl oz marketed
Approximated real-life capacity
48 fl oz
Calculated, not measured: approximated from this product's marketed figure of 271 fl oz, counted as 169 fl oz: figures above 7,000 ml are mostly rated from the materials rather than tested, and run about 1.6 times the ISO test.
Capacity is published two ways: ISO 11948-1 soaks the whole product in salt water (the lab total), DIN 13222 puts it on a test torso and adds liquid until it leaks (closer to use).
Across 280 products whose makers publish both, the second follows a curve: about a third of the ISO total for smaller products, falling to about 28 % at 5,150 ml.
The curve is typically within 12 %, but one product in ten is off by more than 30 %, and what a diaper holds in real use depends on far more: fit, body position, how fast and how often.
