How to Measure for an Adult Brief or Pull-Up

Direct Answer

Measure both waist and hip circumference in centimetres. Use the larger of the two measurements to select the size. Do not guess based on clothing size — underwear sizing and brief sizing use different cuts. A proper fit means the leg elastic sits snugly against the inner thigh without cutting in, and the waistband sits at the natural waistline.

Step-by-Step Measurement

1. Waist: Measure around the narrowest part of the torso, usually just above the belly button
2. Hips: Measure around the widest part of the hips and buttocks
3. Use the larger measurement against the size chart
4. If between sizes, consider body shape: choose the larger size for broader hips, the smaller size for a narrower hip-to-waist ratio if leg sealing is the priority

Checking the Fit

• Leg elastic should create a gentle seal — you should be able to slip one finger under the elastic
• The absorbent core should cover from the lower abdomen to the upper buttocks
• Standing leak guards should stand upright inside the leg cuff, not folded flat
• Tabs should fasten within the designated landing zone without stretching to the limit
• No gap should be visible at the lower back when the wearer is lying down

Common Fitting Mistakes

• Wearing too low: The core misses the urethra entirely
• Wearing too high: The lower buttocks are exposed
• Leg guards tucked in: Urine flows directly out the leg opening
• Tabs too tight: Causes skin damage and tab tearing
• Tabs too loose: Gaps form at the waist and hips
• Wrong size for body shape: A size Large for a tall, narrow person fits differently from a size Large for a shorter, broader person

Size Chart Reference

Always check the manufacturer's specific size chart as measurements vary between brands.
