Every BabyHouse shoe uses standard EU sizing — the one scale that runs seamlessly from newborn (EU 16) through toddler and big-kid sizes, with US conversions below. Ages are only a guide; what matters is how long your child's foot is. A few styles come in combined sizes (like EU 16-17): one roomier size covering that range.
📏 Measure your baby's foot from the heel to the tip of the toe — then find it below.
| Size | Age guide | Fits foot up to | Foot (cm) | Insole length | US approx. |
|---|
Stand your baby on a piece of paper (or hold the foot flat on it). Mark the back of the heel and the tip of the longest toe, then measure between the marks in inches. Measure both feet — go with the longer one.
Each size's insole is about 0.4" longer than the foot it fits, so there's wiggle room without slipping. If your measurement sits at the top of a size, go up one — little feet grow about half a size every 2–3 months.
Every brand labels baby sizes differently, so trust the inches, not the age. Measure first, then pick the size — feet, like babies, do their own thing.
