European kids shoes come in EU sizes, and American parents get one number with no reference point. A size 24 sandal from Spain sits somewhere between a US 7 and a US 8, and the brand decides which. This guide gives you the conversion table, the foot measuring method that works at home, and the growing room rule that keeps a shoe wearable for more than six weeks.

Measure the foot before you look at any chart

Shoe sizes are a translation of one number: the length of the foot in centimeters. Get that number and every chart becomes readable.

1. Tape a sheet of paper to the floor, against a wall.
2. Stand your child on the paper with the heel touching the wall. Standing matters, because the foot spreads under body weight and a measurement taken while sitting comes out short.
3. Mark the paper at the tip of the longest toe. On many children that is the second toe, not the big toe.
4. Measure from the edge of the paper at the wall to the mark, in centimeters.
5. Repeat for the other foot. Feet are rarely identical. Use the larger one.

Measure late in the day. Feet swell as the day goes on, and a shoe fitted in the morning can feel tight by evening.

EU to US conversion for kids shoes

The table below covers the range European kids brands make. Foot length is the number to trust, the US column is the closest common equivalent.

EU size	Foot length	US size	Typical age
19	11.5 cm	4 US	6 to 9 months
20	12.2 cm	5 US	9 to 12 months
21	12.8 cm	5.5 US	12 to 15 months
22	13.5 cm	6 US	15 to 18 months
23	14.2 cm	7 US	18 to 24 months
24	14.8 cm	8 US	2 years
25	15.5 cm	8.5 US	2 to 3 years
26	16.2 cm	9.5 US	3 years
27	16.8 cm	10 US	3 to 4 years
28	17.5 cm	11 US	4 years
29	18.2 cm	11.5 US	4 to 5 years
30	18.8 cm	12.5 US	5 years
31	19.5 cm	13 US	5 to 6 years
33	20.8 cm	1.5 US youth	7 years
34	21.5 cm	2.5 US youth	8 years

Age is the weakest signal in that table. Two children born the same week can be three EU sizes apart. Use age only to sanity check a number you already measured.

How much growing room to add

Add 0.5 to 1 cm to the measured foot length, then pick the EU size closest to that total. Less than 0.5 cm and the shoe is outgrown within weeks. More than 1 cm and the heel slips, which changes how a young child walks.

For a first walking shoe, stay at the lower end. A beginner needs to feel the floor, and a roomy shoe makes that harder.

Where European brands differ from each other

Conversion charts describe length. They say nothing about width, and width is where most returns come from.

• Cienta makes canvas and velvet styles in Spain with a medium width and a rounded toe box. Their Mary Jane styles run true to the table above.
• Shoo Pom is French leather, cut a bit narrower through the middle of the foot. On a wide foot, go up one EU size. See the first steps sandals.
• Aladino makes Spanish leather sandals with an adjustable buckle, which gives you real room to adapt the fit across a season. Example: closed toe Roman sandals.
• Old Soles uses soft leather with a flexible sole for babies in their first month of standing. See the orthopedic baby sandals.

Signs the shoe no longer fits

Children rarely say a shoe is too small. They stop wearing it. Check every six to eight weeks, and act when you see any of these.

• Red marks across the top of the foot or on the heel after a normal day.
• Toes curled at the front when the child stands, which you can feel through the upper.
• The child pulls the shoes off as soon as you get home.
• The sole is worn through at the ball of the foot.

Questions parents ask

Is EU 24 the same as US 8 in every brand?

No. EU 24 lands between US 7.5 and US 8.5 depending on the maker. Measure the foot in centimeters and match that, not the US number printed on a different brand.

Should I buy a size up so the shoes last longer?

Add growing room of 0.5 to 1 cm, not a full size. A shoe that is too long makes a young child trip and drag the heel.

My child is between two sizes. Which one?

Take the larger size in sandals and closed leather shoes, since both stretch a little with wear. Take the smaller size in a soft first walker, where contact with the floor matters.

Do European sizes run small compared to American ones?

They don't run small, they measure differently. EU sizing measures the last, the wooden shape a shoe is built on, and that shape runs longer than the foot inside it. That's why the same child wears EU 25 and US 8.5.

How often should I remeasure?

Every eight weeks up to age three, then every three months. Feet grow in bursts, not on a schedule.
