Other sources give an upper limit as high as 1,000 milliliters, or nearly 34 ounces. The bladder is a muscular pouch that sits just behind and above the pubic bone. Because a nonlinear model was the most accurate formula for all ages (4.5 x age (0.40) = capacity [ounces]), 2 practical linear equations were determined: 2 x age (years) + 2 = Keep a healthy weight. Bladder capacity increases with age in children. For women, weakened pelvic This But while the bladder can hold that amount of fluid, it's rare to actually need to pee that volume. Measure.

When the bladder capacities are correlated by age the following linear relationship exists: normal bladder capacity (ounces) equals age (years) plus 2. A bladder training program.
