When Properly Fit, Adult Diapers Will Not Leak

Is it True That a Larger Diaper is Better?

No. Wearing a larger diaper size than needed can actually increase the risk of leakage. A large diaper does not absorb more liquid than a small diaper. Many people wrongly assume that a larger diaper contains more absorbent fabric than a smaller diaper, simply because of its size. The truth is, each adult diaper and adult pull up is designed to absorb a specific amount of liquid, regardless of its size. Both an extra small adult diaper and an extra large adult diaper can handle the same exact amount of fluid. A high quality, maximum-absorbency adult diaper can easily absorb more than 16 ounces while keeping the wearer’s skin dry and comfortable.

Proper Fit is Key to a Leak-proof Diaper

The proper fit of an adult diaper is equally as important as selecting the correct diaper. Even the best product on the market can leak if it doesn't fit properly. A diaper that is either too large or too small will be not only increase the risk of leakage, but may also increase risk of skin irritation and breakdown. A diaper should have a snug, comfortable fit. If the diaper is too large for the wearer, gaps between the skin and the diaper can occur – and liquid can escape through the gaps. If there is a gap between the diaper and the legs, liquid can escape before being absorbed. The diaper’s leg elastic should be in smooth contact with the skin all the way around both legs. One simple way to ensure a smooth seal after each change is to lightly run your finger underneath the elastic around both legs.

How to Fit/Size an Adult Diaper

A lot of people use sizing guides to find the proper size based on their height and weight. Please refer to our sizing guides for information about fitting of an adult diaper. These sizing guides use your weight and height to help you determine the proper size. They are provided by various manufacturers to guide you in selecting the correct size. it is important to note that sizing charts are not standard and can vary by brand. 

Proper fitting of an adult diaper depends on an accurate hip/waist measurement. If you have the right size, a good diaper, like those we sell on Rely Medical, will not leak.

If you want to find your exact waist size, or the size of someone you care for, follow these few steps:

For Someone Standing: Use a measuring tape to measure the hips or waist, whichever is largest. Place the tape snugly, but not tightly, around the largest area.

For someone sitting or lying down: Place the tape measure from hip bone to hip bone, multiply by 2, and then add 2 inches to the measurement. For example, someone who measures 18 inches from hip bone to hip bone would have a 38-inch waist: 18" x 2 = 36" + 2" = 38"

Take the "Would You Wear It" Test: If you are measuring as a caretaker, take a look at the product once it's being worn and answer the following questions. Then decide whether this is the right size:

  • How does the adult diaper fit at the legs?
  • How much overlap is there on each side?
  • Does it look like a pair of underwear?
  • Is it too loose?
  • Is it too tight?
  • Does the adult diaper shift or bunch up?

It is important to note that bigger is not always better. When it comes to adult briefs and incontinence products, proper fit equals better containment and better comfort. And, in the end, proper adult diaper fit is KEY to comfort and performance.
