How to Measure

Waist Measurement

1

Stand naturally with feet shoulder-width apart

2

Locate your natural waistline (narrowest part of torso)

3

Wrap measuring tape around waist, keeping it level

4

Tape should be snug but not tight - you should be able to breathe comfortably

Hip Measurement

1

Stand with feet together

2

Find the widest part of your hips/buttocks

3

Wrap tape measure around this area, keeping it parallel to floor

4

Ensure tape is not twisted and lies flat against your body

Product-Specific Sizing Notes

Hybrid All-in-One Diapers

These run slightly larger due to the built-in absorbency. If you're between sizes, consider sizing down.

Tip: The velcro adaptation allows for fine-tuning the fit.

Fitted Diapers

These have a more tailored fit. Stick to your measured size for optimal comfort and performance.

Tip: Requires a separate cover for waterproof protection.

Diaper Covers & Swim Diapers

These should fit snugly around the legs and waist to prevent leaks. Size according to your measurements.

Tip: Check leg openings for proper seal without being too tight.
