📏 Find Your Diaper Size

Sizing varies a lot between brands. One measurement — your hip circumference — is the single most reliable guide across all of them.

How to measure

Stand straight with feet together and wear only underwear (or nothing).

Wrap a soft tape measure around the fullest part of your hips — this is usually 7–9 inches below your waist.

Keep the tape parallel to the floor. It should sit flat without digging in.

Note the measurement in inches. Write it down.

Also measure your waist (natural waistline, narrowest point). Use whichever is larger.

📏Measure hips at their widest point — usually around the fullest part of your backside, not your waist.

🧵Use a soft tape measure or a piece of string you then measure with a ruler.

📐Stand straight with feet together. The tape should sit flat, not digging in or drooping.

↕️When you fall between sizes, always size up. A slightly loose diaper is more comfortable and more discreet than one that is too tight.

🔁Try a sample pack first before ordering a full case. Most brands offer 1–3 unit samples.

⚖️If your waist and hips give different sizes, use the larger measurement.
