How do diaper sizes work?

Understanding the right fit for your baby
Choosing the right diaper size is essential for keeping your baby comfortable, dry, and happy. A diaper that is too tight can irritate delicate skin, while a diaper that is too loose can lead to leaks, frequent outfit changes, and extra laundry for busy parents. With a Lofties diaper subscription in Switzerland, parents can ensure they always have the right size delivered directly to their home, avoiding last-minute store runs.

Diaper sizes are based on weight, not age
Diapers are designed according to your baby’s weight rather than age, since babies grow at different rates. While generic diapers may list broad weight ranges, this can lead to a poor fit if your baby is at the lower or upper end of a size. At Lofties, our size guide helps parents select the perfect fit to optimise comfort and minimise leaks.

Lofties diaper sizing guide
Here’s how Lofties diaper sizes correspond to your baby’s weight:

  • Size 1: 2–5 kg
  • Size 2: 4–8 kg
  • Size 3: 7–12 kg
  • Size 4: 10–18 kg
  • Size 5: 14–25 kg
  • Size 6: 20+ kg

 

Each baby is unique, so always check the fit rather than relying on weight alone. For example, Size 1 is ideal for most babies in the first months of life and ensures comfort while keeping skin dry.

How to check diaper fit
A properly fitted diaper should sit gently on your baby’s waist and legs without leaving marks or gaps. You should be able to slip a finger under the waistband easily, and the leg cuffs should rest softly without folding inward. Lofties diapers are designed with soft, snug materials that reduce leaks and allow natural movement, ensuring your baby stays comfortable all day and night.

Preventing irritation
Lofties diapers are hypoallergenic, dermatologically tested, and free from over 200 harmful chemicals. Our snug leg cuffs help reduce friction and spills, keeping skin healthy. If your baby falls between two sizes, choose the size that fits best for comfort, while keeping an eye on the waist and leg openings to ensure proper fit.
