Finding incontinence products that fit correctly can be challenging. Diaper sizes are very different from clothing and require you to do some research in advance. To make things easier, we’ve put together this step-by-step guide on how to choose the right size.

If you care for someone with incontinence, accidents will happen. But selecting the right size of incontinence products (e.g., adult diapers or pull-ups) can prevent leaks, reduce the risk of skin problems, and keep your loved one clean and dry.

Diaper sizes are very different from clothing and require you to do some research in advance. To make things easier, we’ve put together this step-by-step guide on choosing the right size.

What You'll Need

A Flexible Tape Measure

This will allow you to take accurate measurements of your loved one to identify the perfect size incontinence wear for them.

How to Measure

Step one: Take your loved one’s measurements

Before looking for incontinence products, you must determine your loved one’s size. Use a flexible tape measurer to:

  • Measure the width of your loved one’s waist. Keep the tape just below their belly button to ensure accuracy. 

  • Measure the widest part of your loved one’s hips. 

  • Measure the widest part of your loved one’s thighs. The area between their hips and pelvis.

Encourage your loved one to relax while taking the measurements. If their muscles are tense, it can throw off the sizing by up to an inch. 

Pro tip: Never buy incontinence products based on your loved one’s pant size. Diapers and pull-ups are typically worn just below the belly button so the measurements won’t be the same.

Step two: Compare the measurements to a product size guide

After collecting your loved one’s waist, hip, and thigh measurements, compare them to an incontinence product size chart.

Most manufacturers provide size brackets featuring waist and hip measurements (e.g., waist/hip: 17”-28”). They also provide information about suggested weight, absorbency capacity, and quantity. 

The two most important numbers are the waist and hip measurements. When in doubt, select the larger number. If your loved one’s diaper or pull-up is too small, it won’t provide enough coverage or protection.

Parmeet Kaur, PT, a specialist in pelvic floor physiotherapy at Brentwood Physiotherapy Clinic in Calgary, Toronto, says that although sizing charts can be helpful, “It's important to remember that there is no universal size chart when it comes to adult incontinence products.”

“Each product may require a different size and fit depending on the brand or style you choose.

Before making your purchase, be sure to read all the sizing information available so that you get the best fit for your needs. With the right size, you can enjoy a comfortable and secure fit that will keep you dry and confident throughout the day.”

Step three: Consider other important factors

Taking your loved one’s measurements is crucial when selecting incontinence products, but it’s not the only thing to consider. 

You need to account for several other factors as well, including:

  • Comfort. Adult incontinence products are woven from soft, clothlike materials, allowing the skin to breathe. Many are also free of allergens, such as latex and gluten.

  • The type of incontinence. What type of incontinence does your loved one have? Some products are made specifically for urinary or fecal incontinence; while others support both types.

  • Tabs or No Tabs. Adult diapers have tabs or closures, making it easier to ensure a perfect fit. Pullups don’t have tabs or closures. Instead, they feature tearable side panels that can be easily ripped away.

  • Snug. Snug refers to how the diaper rests against your loved one’s skin. A diaper that’s too snug may cut off circulation or cause a rash. Whereas a diaper that isn’t snug enough may leak.

  • Absorbency. Incontinence products have different levels of absorbency. If you’re buying diapers or pull-ups for the first time, we recommend buying several different absorbency types. After some trial and error, you can determine which products you and your loved one prefer.

Don’t worry about making the “wrong” decision. If a particular product doesn’t fit or your loved one doesn’t like it, that’s okay. There are a variety of adult diapers and pull-ups designed for people of all shapes and sizes. 

Step four: Browse our selection of incontinence and toileting products

Adult diapers

Hear it from Caregivers

“I’m new to these products, so am kind of experimenting with different ones. [Some diapers] have a long tab instead of two separate tabs, which I like. I am ordering a different diaper for night use. They are great at absorbing and strength.” - Kathy L.

“Good quality diaper[s]. Fit well!” - Francis T.

“First time customer and very pleased with the customer service and prompt delivery just like they promised. I will definitely continue to order from Carwell.” - Victor M.

Common Myths About Adult Diapers and Pull Ups

Myth #1: Big diapers provide more absorbency

Modern incontinence products (regardless of size) have wicking technology that draws moisture away from the skin. If there’s a choice between fit and absorbency level, always choose ft. 

Myth #2: Some diapers just have a loose fit

A diaper that’s loose or baggy is an accident waiting to happen. 

Make sure the waist of the incontinence product is snug against your loved one’s skin. The leg gathers should hug their thighs, but the diaper shouldn’t bunch up or pinch them when they stand up or walk around.

Myth #3: Adult diapers and pull-ups cause skin problems

Wearing incontinence products may irritate your skin, but selecting the right size and changing the products frequently can significantly reduce your risk. The diapers and pull-ups that we carry are soft, breathable, hypoallergenic, and antibacterial.
