How to Measure for Incontinence Products: A Complete Sizing Guide
How to Measure for Incontinence Products
Choosing the right size is not just about comfort. A better fit can help reduce leaks, support skin health and make pads, pants or briefs feel more secure during everyday movement.

For most adult incontinence products, measure around the widest area between the waist and hips.
Do not rely only on clothing size. A medium in everyday underwear may not match a medium in incontinence pants, briefs or fixation products.
A product that is too large can leak just as easily as one that is too small.
Many leakage issues come from gaps around the legs, poor positioning or a product that cannot stay close to the body during movement.
Why the Right Size Matters
When an incontinence product leaks, many people assume they need the highest absorbency available. In reality, fit is often just as important as absorbency. Leading continence brands such as ABENA, MoliCare, TENA and Medline all place strong emphasis on correct sizing, product style and body-close fit when choosing an incontinence aid.
A correctly sized product sits closer to the body and helps the leakage barriers, leg elastics or cuffs work as intended.
A good fit should feel secure without digging into the skin, rolling down or creating bulky folds under clothing.
Reducing leaks and excess moisture can help protect sensitive skin from prolonged exposure to urine or faeces.
How to Measure for Incontinence Products
Use a soft measuring tape and measure gently. The tape should sit flat against the body without pulling tight. If possible, measure over light clothing or underwear, not thick layers.
Measure the widest point between the waist and hips
For many adult incontinence pants and briefs, the best starting point is the widest area around the body, usually around the hips or between the waist and hips. This is more reliable than guessing from clothing size.
- Keep the tape level all the way around.
- Do not pull the tape too tightly.
- Write the measurement down in centimetres.

Compare the number with the product’s own size guide
Each brand and product range may fit differently. Always compare your measurement with the size chart for the specific product you are buying, especially when changing from one brand to another.
For example, the sizing range for TENA pants may not be identical to MoliCare, ABENA or Medline products.
Check the fit after the product is worn
After applying the product, check around the waist, hips and legs. There should be no large gaps, twisting or folded material. The product should stay in place when the person sits, stands or walks.
Common Sizing Mistakes That Cause Leaks
The right size should support the product’s absorbent core and leakage barriers. The wrong size can stop these features from working properly.
A larger product is not always more protective. If it is too big, it may create gaps around the legs or waist, allowing urine to escape before it reaches the absorbent core.
Try this: Choose absorbency based on leakage level, but choose size based on body measurement.
Everyday clothing sizes are inconsistent. They also do not account for the absorbent core, leg barriers, fixation system or product style.
Try this: Use the manufacturer’s size guide for the exact product range.
A product can fit while standing but move out of place when walking, sitting, transferring or lying down.
Try this: Recheck fit during the activity when leaks usually happen.
Different brands use different cuts, materials and sizing ranges. A size that works in one range may not perform the same in another.
Try this: Recheck measurements and sizing charts whenever changing brands.
Signs Your Incontinence Product Is Too Big or Too Small
| What you notice | Possible fit issue | What to try first |
|---|---|---|
| Leaks from the leg area | Product may be too large, poorly positioned or not close enough to the body | Check leg fit, remeasure hips and compare with size chart |
| Red marks, digging or discomfort | Product may be too small or fitted too tightly | Check the next size up or a different product style |
| Product slides down while walking | Size may be too large or product style may not suit mobility level | Consider pull-up pants or a more secure brief style |
| Tabs do not fasten securely | Brief may be too small or incorrectly positioned | Remeasure and check application technique |
| Frequent overnight leaks | May involve saturation, sleeping position, sizing or product type | Review night-time absorbency and fit; consider bed protection as backup |
Different Product Types Fit Differently
Sizing is not the same across pads, pull-up pants, briefs and fixation systems. The right product depends on leakage level, body shape, mobility and how much assistance the person needs.
Pads & liners
Often used for light to moderate leakage. Fit depends on correct placement and secure underwear or fixation.
Pull-up pants
Useful for people who walk independently and prefer an underwear-like feel.
All-in-one briefs
Often suitable for heavier leakage, reduced mobility or when a caregiver assists with changes.
Bed & chair protection
Helpful as an added layer for overnight leakage, bedbound care or surface protection.

What If You Are Between Two Sizes?
If your measurement falls between two sizes, do not automatically choose the larger option. The better choice depends on where leaks happen, how the product feels and whether the wearer is active, seated or mostly lying down.
If the product feels loose or leaks at the sides
The smaller size may create a closer fit, especially around the legs. Make sure it is not tight or restrictive.
If the product feels tight or leaves marks
The larger size or a different cut may be more comfortable. A too-tight product can cause discomfort and may not sit correctly.
Quick Size & Fit Checklist
Use this before deciding that a product does not work for you.
- I measured the widest area between waist and hips.
- I checked the exact size guide for this product.
- The product sits close to the body without gaps.
- The product does not dig into the skin.
- Leg cuffs or barriers are not folded inward.
- The product stays in place when sitting or walking.
- I chose absorbency based on leakage level, not size.
- I reviewed whether pads, pants or briefs best suit my mobility.

Frequently Asked Questions
Should I measure my waist or hips for incontinence products?
For many adult incontinence products, the safest starting point is the widest area between the waist and hips. Always compare your measurement with the product’s own size guide.
Can a product leak because it is too big?
Yes. A product that is too large can create gaps around the legs or waist, allowing leakage before fluid reaches the absorbent core.
Can a product leak because it is too small?
Yes. A product that is too small may not sit correctly, may feel tight, and may reduce the effectiveness of the absorbent area and leakage barriers.
Are incontinence product sizes the same across brands?
No. Sizing can vary between brands and product ranges. Always check the exact size guide for the product you are buying.
What should I do if I am between two sizes?
Look at the fit problem. If the product is loose or leaking from the sides, the smaller size may be better. If it feels tight or leaves marks, consider the larger size or a different product style.
Does higher absorbency mean I should choose a larger size?
No. Size and absorbency are different decisions. Choose size based on body measurement, and choose absorbency based on leakage level and change frequency.
Still Unsure Which Product Fits Best?
A correct measurement is the first step. The next step is choosing a product type that matches leakage level, mobility and daily routine.
