In short
Where the number just works. At 9-10 years (S), 11-12 years (M), 13-14 years (L), Adidas Kids lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 2T, Garanimals, Macy's Epic Threads, Macy's First Impressions cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Adidas Kids number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Fit & the transitions that trip parents up
Adidas Kids-specific things the size number alone won’t tell you — drawn from its own charts.
One unisex chart, labelled by age
adidas kids charts a single unisex ladder — baby and toddler sizes, then kid sizes labelled by age range, from 5–6 years up to 15–16 years. There’s no separate boys’ and girls’ sizing to reconcile.
Slim, tapered legs; a looser pull-on waist
The signature track pants and joggers (Trefoil, Tiro) run lean and tapered through the leg — several parents size up for a snug calf — while the elastic waist tends to run loose on a slim child. Length is generally fine; it’s the silhouette that reads streamlined, not the sizing.

What shoppers say about the fit
Community consensus
Shopper opinion · not Little & Youth’s measurementThis is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Adidas Kids’ own published chart; the notes here come from public parent discussion.
adidas kids runs slim through the leg, with a roomy pull-on waist. The signature track pants and joggers (Trefoil, Tiro) are cut on a lean, tapered athletic line — several parents find the pegged leg snug at the calf and size up for it — while the elastic waist tends to run loose on a slim child. Length is generally fine; it’s the silhouette that reads streamlined rather than the sizing running off in either direction.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy Adidas Kids?
Consider it if…
- You want recognizable athletic style — the three-stripe track pieces and Trefoil logo carry real playground appeal.
- You want durable activewear — built for movement and hard wear.
- You want a sporty, streamlined look — the tapered cut is the point for many kids.
Think twice if…
- You want a relaxed, roomy leg — the tapered/pegged cut is deliberately slim.
- You want dressy or classic pieces — it’s activewear, not occasion clothing.
- You need a snug waist without adjustment — the pull-on elastic can sit loose on slim kids.
Skip the cross-referencing — let Little & Youth do it.

Do adidas kids joggers run slim?
Yes — the Trefoil and Tiro track pants are cut on a tapered, pegged leg that several parents find snug at the calf, so a broad or muscular child often sizes up. The pull-on elastic waist, by contrast, runs a little loose on slim kids.
Is the length true to size on adidas track pants?
Length generally runs true; the fit story is the slim leg and the roomy waist, not the length. If your child is between sizes and lean, the waist may be the deciding factor.
What measurements do I need to size Adidas Kids accurately?
Adidas Kids publishes height, chest, waist, hip, inseam in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
How do Adidas Kids’ shoe sizes work?
Adidas Kids’ shoes fit true to size, and they’re cut wide-friendly. Kids’ shoe sizes go by foot length, not age — measure your child’s foot and match it to the size. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.

Adidas Kids is sold on its own site and on Amazon, so you can pick the marketplace you prefer.
