Diaper Size by Weight Converter

| Size | Weight (kg) | Weight (lb) | Match |
|---|
This is only a guide, not medical advice. Every brand fits a little differently — check the fit: two fingers of space at the waist and no marks on the legs.
How to use
- Enter your baby weight in kg or lb.
- Press Find Size — the recommended size and the full chart will appear.
- If the weight falls between two sizes, take the bigger size (for comfort).
Tips
- If the weight sits between two sizes, choose the bigger size for comfort.
- Size charts differ slightly by brand — check the pack chart when switching brands.
- Red marks on the skin usually mean the size is too small.
