Korean Diaper Size Matcher
Recommend diaper sizes across 6~8 Korean brands by baby weight, age, and use type. Monthly consumption + border alerts.
About this tool
Korean Diaper Size Matcher takes baby weight, age, and use type (day / night / swim / training pants) and compares the official weight tables of 6+ Korean-distributed brands β Huggies, Pampers, Mamy Poko, Nature Love Mere, Coupang Green, GoodNites β to recommend the best current size and the weight at which the next size kicks in. Estimates monthly consumption (10β12/day for newborns down to 6β7/day at 12 months) and monthly cost using average market prices. Brand sizing tables differ by 1β2 kg per tier, so the comparison shows exactly where, e.g., "Huggies 4" and "Pampers L" overlap. All inputs stay in your browser.
Use cases
Scenario 1
First week with a newborn
Parents of a 3.2 kg newborn compare "newborn" vs. "size 1" boundaries across six brands and buy a one-week supply.
Scenario 2
Night-leak fix during seasonal change
For a 6-month 7 kg baby with frequent dawn leaks, get a recommendation to size up at night and recalculate monthly usage.
Scenario 3
Switching brands
For a 9 kg baby outgrowing Huggies size 3, compare Pampers L vs. Huggies 4 ranges side-by-side to decide.
Scenario 4
Bulk vs. weekly purchase decision
When the tool warns the baby is at a borderline weight, decide between a bulk box and a weekly pack to minimize waste.
Scenario 5
When to start training pants
Check the 18β24 month window for switching to training pants by weight and age, and plan separate day-vs-night usage.

Frequently asked
- Q. Why do brand sizes differ at the same label?
- A. Each brand sets its own ranges (Huggies 4 = 8β13 kg, Pampers L = 9β14 kg). The tool plugs your weight into every brand at once.
- Q. What is normal monthly consumption?
- A. Roughly 300β360/month for newborns, 240β270 at 3β6 months, 180β210 around 12 months β add 10β20% if you keep separate night / outing packs.
- Q. Day vs. night diapers β what changes?
- A. Night diapers assume 10β12 hours of wear with thicker absorbent pads and stronger leak guards. They cost 15β30% more but cut night leaks dramatically.
- Q. At a borderline weight, should I size up?
- A. Within 0.5 kg of the boundary, keep the current size unless red marks appear; oversizing widens leg gaps and increases leaks.
- Q. Is baby data stored anywhere?
- A. No. Calculation runs entirely in the browser; only the last input is cached in localStorage for convenience.
