How to know what size adult diapers to buy?

4 min read

According to research published in the Journal of Wound Ostomy and Continence Nursing, over 11% of Medicare recipients were diagnosed with incontinence in 2018. Knowing how to know what size adult diapers to buy is critical for both comfort and dignity, ensuring optimal performance and preventing leaks.

Quick Summary

Selecting the right adult diaper size involves measuring both the waist and hips, then using the larger of the two measurements to consult the specific brand's size chart. Proper fit is crucial for comfort, skin health, and reliable leak protection, so never assume your size based on other clothing or brands.

Key Points

  • Accurate Measurement is Key: Always measure both the waist and hips and use the larger number to find your size on a brand's specific chart.

  • Fit Over Guesswork: Never rely on clothing size or assumptions from other brands; sizes are not standardized in the incontinence product industry.

  • Recognize the Signs: Red marks mean too tight; sagging or leaks often mean too loose. Check for pinching, chafing, or gaps to identify a poor fit.

  • Choose by Mobility: Select briefs with tabs for less mobile individuals requiring caregiver changes, and pull-ups for more active wearers who can change independently.

  • Absorbency vs. Size: Consider absorbency needs when evaluating fit, as a higher absorbency product may feel bulkier but is necessary for greater protection.

  • When in Doubt, Test: If your measurements are between sizes, try sample packs of both sizes to determine which offers the best fit and comfort for your specific needs.

The Importance of Proper Diaper Fit

Choosing the correct size is the single most important factor for an effective adult diaper. A poorly fitting product can lead to numerous problems, affecting not only physical comfort but also emotional well-being. A diaper that is too small can chafe, restrict movement, and cause skin irritation, potentially leading to rashes or even skin breakdown. It also increases the risk of embarrassing leaks, as the material can become over-stretched or tear.

Conversely, a diaper that is too large will sag and create gaps around the legs and waist. These gaps are prime locations for leaks, especially when lying down or moving. The extra material can also feel bulky, uncomfortable, and less discreet under clothing. An optimal fit ensures the absorbent material is held snugly against the body where it's needed most, maximizing both absorption and containment.

Step-by-Step Guide to Measuring

To determine the right size, you will need a flexible tape measure. Do not rely on your regular clothing size, as incontinence product sizing often differs and is designed for a specific purpose. Follow these steps for the most accurate measurement:

  1. Measure the Waist: Wrap the tape measure snugly around the natural waistline, typically around the navel. Ensure the tape is parallel to the floor and not pulled too tightly. Record this measurement.
  2. Measure the Hips: Stand with your heels together and measure around the fullest part of your hips and buttocks. This is the hip circumference. Note this measurement as well.
  3. Find the Larger Measurement: Compare your waist and hip measurements. The larger of these two numbers is the one you will use to match with a product's size chart. Using the largest part of the body ensures a secure seal that prevents leaks.

Special Considerations for Body Types

Body shape can influence the best fit, even with accurate measurements. For individuals with a fuller midsection, paying close attention to the hip measurement is often more important. For very tall or shorter individuals, some brands offer extended-rise options to ensure full coverage. It's important to remember that sizing isn't standardized across all brands, so what's a 'Medium' in one brand might be a 'Large' in another. Always check the manufacturer's specific sizing chart.

Choosing Between Briefs and Pull-Ups

The correct fit also depends on the product style. Understanding the differences is key to making the best choice for the wearer's needs and mobility.

Feature Briefs (with tabs) Pull-Ups (protective underwear)
Mobility Level Best for individuals with limited mobility, bedridden, or those who need caregiver assistance. Ideal for active, mobile individuals who can pull them on and off independently.
Application Can be applied while lying down, making changes easier for caregivers and immobile users. Applied like regular underwear, requiring the user to be able to stand and bend.
Fit Highly adjustable due to refastenable tabs, accommodating various body shapes, including bariatric sizes. A snug fit is crucial. If too loose, gaps will form, leading to leaks. Stretchy sides aid comfort.
Absorbency Often available in higher absorbency levels, including overnight options with more extensive coverage. Absorbency varies, with discreet designs for light to moderate incontinence and more robust options for heavier needs.

Recognizing the Signs of an Ill-Fitting Diaper

Even with careful measuring, a test wear is often necessary to confirm a good fit. Look for these signs that indicate the size is wrong:

  • Leaks: The most common sign. Frequent leaks when the absorbency should be sufficient usually means the product is either too loose, causing gaps, or too small and tearing.
  • Red Marks: Redness, chafing, or deep indentations around the waist or legs are a clear sign that the diaper is too small and is digging into the skin.
  • Sagging or Bunching: If the diaper sags, bunches up, or shifts noticeably during movement, it is likely too big. This creates gaps and reduces discretion.
  • Tabs Overlapping (on briefs): For tab-style briefs, if the tabs overlap significantly, the diaper is too large. They should fasten securely on the landing zone without overlapping.
  • Discomfort: A general feeling of restriction, pinching, or tightness indicates a diaper that is too small. Remember, the fit should be snug, not tight.

Adjusting for Absorbency Needs and Lifestyle

Sizing isn't only about measurements; it's also about usage. Someone with high absorbency needs may find that a bulkier overnight product in their size feels tighter than a daytime pull-up. This is normal and a necessary trade-off for increased protection. If you are experiencing leaks but the fit seems right, consider increasing the absorbency level or using a booster pad instead of changing the size.

What to Do If You Fall Between Sizes

If your measurements place you right between two sizes on a brand's chart, your final decision should depend on personal preference and body shape. If you prefer a snugger fit for extra security against leaks, especially if you have slimmer legs, consider sizing down. If comfort and freedom of movement are your priority, or if you have a fuller midsection, sizing up might be a better choice. Many brands offer sample packs, which are a low-cost way to test both sizes before committing to a larger purchase.

Conclusion

Finding the right-sized adult diaper is a straightforward process that begins with accurate waist and hip measurements. By comparing these figures to a product's specific size chart and understanding the nuances between different styles, you can select a product that offers maximum comfort, dignity, and leak protection. Remember to observe how the diaper fits and feels during activity to ensure it’s providing the best possible support. A well-fitting diaper is a vital tool for maintaining quality of life for those managing incontinence.

No, adult diaper sizes are not standardized like regular clothing. Always consult the specific brand's size chart, as a medium in one brand may differ from another.

Briefs with tabs offer more adjustability for a precise fit and are easier for caregivers to change. Pull-ups require a more exact sizing match, as they rely on a stretchy waistband for a secure, comfortable fit.

If you are between sizes, consider your preference for a snugger or looser fit. Many brands offer sample packs, which allow you to try both sizes to find the best fit before buying in bulk.

A diaper that is too big will often sag, bunch up, and have noticeable gaps around the legs or waist. This extra space provides room for leaks, especially when the wearer is lying down.

A diaper that is too small can cause chafing, redness, or red marks around the waist and legs. It may also tear at the seams during movement, leading to leaks and skin irritation.

While absorbency level doesn't change your measurements, a higher-capacity product may feel bulkier. If you need more absorbency but find the product uncomfortable, it is still best to get the correct size and potentially add a booster pad, rather than sizing up.
