What Does PS Stand for in Shoe Sizes
PS in shoe size stands for “preschool.” Babies can grow into children almost in a blink of an eye. Their shoe sizes will change drastically throughout different stages of development. For that, manufacturers grouped children’s shoe sizes into different categories accordingly.
You will mostly find these terms, including the PS size meaning, on StockX:
- I: Infant (1 year or younger)
- TD: Toddler (1 to 3 years old)
- PS: Pre-school (3 to 5 years old)
- GS: Grade school (6 to 12 years old)
- W: Women’s
- M: Men’s
In other references, the grade school sizes are further broken into genders: Girl Grade School (GG) and Boy Grade School (BG).
However, major brands like Adidas, Nike, Reebok do not seem to use these terms on their official websites.
For these brands, the sizes for newborns up to six-year-olds are tagged with “C” while sizes for older children up to 12 years old are tagged with “Y,” e.g. “10C” or “12Y.” This way, buyers can tell that they are not adult sizes.
In any case, below, you will find the PS to US, UK, and EU sizes in centimeters.

Tips for Measuring Your Children’s Shoes
For accurate measurements:
- Trace your child’s foot on paper.
- Measure during the afternoon when their feet are largest. Also, measure both their feet and take the measurements of the larger one for buying shoes.
- Add one 1cm to the measurement to provide ample wiggle room for growth. Remember, children grow very quickly!
- Don’t just fit the shoes while standing and taking a few steps—get your child to jump, crouch, or bend over while in the store. Ideally, the shoes should not hinder their movement.
