It seems no two manufacturers use the same language to describe their products. What's "moderate protection" to some is "heavy protection" to others.
To help you sort it out, we’ve developed a standardized Total Capacity Rating system that we use across all brands and incontinence products we sell.
At a glance, the rating shows a product’s ability to absorb and hold bladder and bowel leakage.
Typical Bladder Void Volume for Adults vs Kids
Let's talk specifics. Did you know that adults pass an average of 1 cup (8 ounces or 237 ml) of urine at a time?
Kids are different - there's a calculation based on their age. Look for the "Urine Output Calculation" section to learn more.
For adults, 1 cup is what's considered a 'full' pee (or, 'void' if you prefer).
When shopping for incontinence products, there are three ways of looking at a person's absorbency needs:
- How quickly does the product absorb?
- How much does it hold: drips, leaks, a full void, or multiple voids?
- How dry does it stay?
This is where it becomes critical for you to decide what you're looking for, based on your needs. Are you looking for protection against:
- Occasional drips over several hours? Or
- Small, unexpected leaks (like after a sneeze)? Or
- Slightly larger leaks - like after you lift something, or jump or skip - that leave you feeling wet?
- Or, unpredictable, full (and possibly repeat) voids where you need to change your clothes?
Understanding the protection you need - which can also change over time - is the key to picking the right product. Perhaps you need LIGHT protection during the day but MAXIMUM protection overnight. We've explained what each rating level means below:
Watch for the rating on every product listing on our site to make sure the products you choose are right for you.
