Why age charts mislead
Age-based size charts survive because they are convenient, not because they are accurate. Two children of the same age can sit several size steps apart - growth does not arrive on a schedule, it arrives in spurts that differ per child. An age chart hides that spread behind a single column, and the buyer who plans a program from it orders a size run shaped like a spreadsheet instead of like a classroom. A child can move two size steps inside a school year, and the direction is always one way - which is why kids' shoes are bought with an eye on the near future, not just the current fit. An age chart cannot see that; a measured foot can. The honest unit of kids' sizing is the same as the adult one: foot length, heel to longest toe, measured standing, matched to the chart's centimeter band.
The second problem with age charts is the scale itself. Kids' sizing ladders differ by market - US kid and youth scales are separate systems from US men's and women's scales, and parents shopping across borders get tripped by identical numbers meaning different feet. The conversion table the desk works from maps EU steps to US men's and women's columns with a foot-length anchor; kids' scale printing is confirmed per program on the spec sheet rather than assumed from a chart.
What the desk's stock runs cover
On the stock route, the smaller-foot band sits at EU 36-41. Several runs in the current list live there - a kids' chunky sneaker, a trail-style runner and a rugged casual runner - all packed 12 pairs per carton in a size run that steps 1-2-3-3-2-1 across the six steps. Read against the conversion table, that band serves older kids and smaller-foot buyers: EU 36-41 spans the rows that map to the smaller end of the adult scales. The exact runs on hand change as cartons ship, so the live list is confirmed at RFQ - see the stock route for how the list is presented. Runs in this band ship 12 pairs per carton like every other run on the list, and mixed models can share a carton where a program wants two styles in one delivery - which is how school-sized budgets usually start.
| Style ref | Type | Sizes | Pairs per carton |
|---|---|---|---|
| CH7-1 | Kids' chunky sneaker | 36-41 | 12 |
| CH26 | Trail-style runner | 36-41 | 12 |
| 3300-1 | Rugged casual runner | 36-41 | 12 |

Reading EU 36-41 against US expectations
By the desk's approximate conversion table, EU 36-41 covers foot lengths of roughly 22.5 to 26.5 cm. On the US men's column that is roughly sizes 4 to 8.5; on the US women's column, roughly 5.5 to 10 - approximate throughout, and brands vary. For a US-facing kids' listing, the practical move is not to convert into a kid-scale figure at all: publish the foot-length band, show the EU step beside it, and let the measured foot choose the row. Parents measure the foot once and the number works across every listing that carries the same column - which is why the measuring note on how to measure foot size matters double in the kids' aisle, where the shopper is measuring someone else's foot.
Growing room is the kids' fitting question adults do not face. The working convention is the same thumb-width rule used for adults - space at the front of the shoe, checked standing - applied a touch generously, because the foot will use it sooner. Generous does not mean a full size up: a shoe that is too long lets the foot slide forward, and the toes grip to hold it, which is its own fit problem. The rule and its failure modes are in the note on toe box room.
Width rides along in kids' fittings too: a growing foot often needs forefoot volume more than it needs length, and a round, deep toe box in the correct band beats a longer shoe in a narrow last. The style families that tolerate width are the same ones at adult sizes, and the same top-down photo test applies. Kids' chunky builds earn their popularity partly here - the silhouette is generous where children's feet actually need it.
School and uniform programs size differently again: the buyer is ordering a population, not a person. The desk works from a size profile - which steps the group clusters in, what the boundary spread looks like - and builds cartons to match, mixed models allowed where the program carries more than one style. A profile taken from measured feet beats an age table every time, and it takes one measuring session to produce. The desk keeps the profile on the program sheet, so replenishment mid-season matches the shape of the first order.
For sellers: scales, labels and the compliance layer
Three things separate a kids' listing from an adult one. First, the scale: state explicitly which ladder the sizes printed on your page belong to, because kids' scales, women's scales and EU steps are all in circulation, and parents convert in their heads badly. Second, the chart: keep the foot-length column visible beside the size selector, with the measuring instructions linked, since the shopper is measuring a squirming child and needs the standing rule more than anyone. Third, the compliance layer: children's footwear sold in the United States enters CPSIA territory - third-party testing at a CPSC-accepted lab, a Children's Product Certificate and tracking labels. That is a program-level topic; the desk's summary sits on the compliance page, the dedicated note is kids shoes and CPSIA, and the testing plan for your program is confirmed with a compliance adviser. And keep the returns loop kind: parents exchange kids' sizes constantly, and a page that teaches measuring and states the scale plainly turns those exchanges into loyalty rather than frustration.
If you are building a kids' range, the desk works from your market's foot-length profile rather than from an age table: name the channel in the request form, and the size runs and scale printing come back on the program sheet in writing, where they can be checked before cartons move.
