How to measure your child at home

Before you look at any chart, get two measurements: foot length (for shoes) and chest, waist, and height (for clothing). It takes less than five minutes and removes all the guesswork.

1

Trace the foot

Stand your child on a sheet of paper and trace around their foot, keeping the pen vertical.

2

Measure heel to toe

Measure the longest distance in centimetres. Do both feet — use the larger measurement.

3

Add growing room

Add 0.8–1 cm for comfortable fit and growing room. Children's feet grow fast — check every 3 months.

4

Match to chart

Use the foot length (in cm) to find the right size in each brand's chart below.

💡 Rookie Tip

Measure in the afternoon — feet are slightly larger after a day of activity and this gives a truer fit. Always measure standing, not sitting.

Universal shoe size reference chart

Use this chart to convert between US, UK, EU and CM sizing. All Rookie Kids shoe sizes follow US sizing conventions.

Age (approx) Foot cm US Size UK Size EU Size Category
4–5 yrs 14.5–15.5 cm 8C–9C 7.5–8.5 24–26 Toddler/PS
5–6 yrs 15.5–16.5 cm 9.5C–11C 9–10 27–28 Pre-School
6–7 yrs 16.5–17.5 cm 11.5C–12.5C 10.5–11.5 29–30 Pre-School

*Highlighted rows mark the transition zone from Pre-School to Grade School sizing — the most common source of sizing confusion.

Nike Kids Sizing

Nike footwear

Nike kids footwear is split into three categories: Toddler (TD), Pre-School (PS), and Grade School (GS). For most children aged 7 and above, you'll be shopping in the Grade School range — these are the iconic silhouettes like the Air Force 1 and Dunk Low in kid sizes.

Nike Fit Tip

Nike GS shoes run true to size but we recommend sizing up half a US size if your child wears thick socks or their foot is between two sizes. The Nike "Lace It Up" collection currently in-store has a slightly roomier toe box — perfect for active kids.

Age Foot cm US (GS) EU Category
5–6 yrs 14.5–16 cm 10.5C–12C 27–29 Pre-School (PS)
6–7 yrs 16–17.5 cm 12.5C–1Y 30–33 PS / GS
7–9 yrs 17.5–20 cm 1.5Y–4Y 33.5–36.5 Grade School
9–12 yrs 20–22.5 cm 4.5Y–6.5Y 37–39.5 Grade School
12–15 yrs 22.5–25 cm 7Y–8Y 40–42 GS / Youth

Nike kids clothing

Nike clothing sizes are based on age and chest measurement. The Nike "In The Zone" and "Victory Lap" collections — both available now at Rookie Kids — use standard Nike sizing.

Nike Size Age Height (cm) Chest (cm) Waist (cm)
4T / XS 3–5 yrs 98–110 53–57 50–53
S 5–7 yrs 110–122 57–62 53–56
M 7–9 yrs 122–132 62–68 56–60
L 9–11 yrs 132–143 68–74 60–65
XL 11–13 yrs 143–155 74–81 65–70
XXL 13–15 yrs 155–165 81–88 70–75

Jordan Kids Sizing

Jordan footwear

Jordan Brand uses the same PS/GS system as Nike (they share sizing infrastructure), but Jordan silhouettes like the Air Jordan 1 and Jordan 6 have specific fit notes. The "Love Is In The Air" and "In The Paint" collections — both live on Rookie Kids right now — feature Grade School sizing.

Jordan Fit Tip

Air Jordan 1s in GS sizing tend to run half a size small due to the stiff leather upper. Go up half a size. Jordan 6 and Jordan 11 run true to size with a wider toe box — great for wider feet.

Age Foot cm US (GS) EU Silhouette Note
6–7 yrs 15.5–17 cm 11C–12.5C 28.5–30 PS range
7–9 yrs 17–19.5 cm 1Y–3.5Y 33–35.5 GS — most styles start here
9–12 yrs 19.5–22 cm 4Y–6Y 36–38.5 GS — widest selection
12–15 yrs 22–24.5 cm 6.5Y–8Y 39–42 GS / Youth — AJ1 size up 0.5

Jordan kids clothing

Jordan Brand clothing runs similarly to Nike. The "Flowers Of Friendship" collection has a relaxed, slightly oversized fit — size down if your child prefers a more fitted look.

Jordan Size Age Height (cm) Chest (cm)
S (6–7) 6–7 yrs 111–122 57–62
M (8–9) 8–9 yrs 122–132 62–68
L (10–12) 10–12 yrs 132–148 68–76
XL (13–15) 13–15 yrs 148–163 76–84

Levi's Kids Sizing

Levi's kids jeans & bottoms

Levi's kids sizing is based on waist and length (slim, regular, husky). The "Bearhug" and "Coastal Creative" collections — both available at Rookie Kids — use Levi's standard kids sizing. Important note: Levi's kids denim runs slim through the waist. If your child is between sizes, size up.

Levi's Size Age Height (cm) Waist (cm) Inseam (cm)
4 Slim 4–5 yrs 98–107 51–53 43
5 Regular 5–6 yrs 107–114 53–55 47
6 Regular 6–7 yrs 114–122 55–57 51
7 Regular 7–8 yrs 122–128 57–60 55
8 Regular 8–10 yrs 128–137 60–63 58
10 Regular 10–12 yrs 137–147 63–66 62
12 Regular 12–14 yrs 147–157 66–69 66
14 Regular 14–16 yrs 157–165 69–73 70

Levi's Fit Tip

Levi's 511 Slim and 510 Skinny run very slim — consider the 514 Straight or 505 Regular for more comfort room. The Bearhug collection has a specially designed soft waistband that adjusts 2–3 cm, making it ideal if your child is between sizes.

Converse Kids Sizing

Converse footwear

Converse Chuck Taylor All Stars are iconic — but they size differently from Nike. Converse runs large and has no arch support, which affects fit. The "Bleacher Society" collection at Rookie Kids is available in Pre-School and Grade School sizing.

Converse Fit Tip

Converse Chuck Taylors typically run 1–1.5 sizes larger than Nike. If your child is a Nike GS 4, try a Converse 3. The canvas upper has some give, so err on the side of a snugger initial fit.

Age Foot cm Converse US EU Nike Equivalent
5–6 yrs 15–16 cm 9C–10C 26–27 10.5C–11.5C
6–8 yrs 16–18 cm 11C–13C 28–31 12C–1.5Y
8–11 yrs 18–21 cm 1–3.5 33–36 2.5Y–5Y
11–14 yrs 21–23.5 cm 4–6 36.5–38.5 5.5Y–7.5Y

Hurley Kids Sizing

Hurley clothing & swimwear

Hurley kids sizing is straightforward and age-based. Board shorts and swimwear use waist measurement. Hurley tops run true to size with a slightly relaxed, surfer-inspired fit — perfect for warm-weather beach and pool lifestyle.

Hurley Size Age Height (cm) Chest (cm) Waist (cm)
4T 3–4 yrs 96–104 52–55 49–52
5 4–6 yrs 104–116 55–59 52–54
6 5–7 yrs 116–122 59–63 54–56
7 6–8 yrs 122–128 63–67 56–59
8 7–9 yrs 128–135 67–71 59–62
10 9–11 yrs 135–147 71–76 62–65
12 11–13 yrs 147–158 76–82 65–69
14/16 13–15 yrs 158–168 82–88 69–73

Clothing size guide by age — all brands at Rookie

When in doubt, use this quick-reference chart covering all brands stocked at Rookie Kids. Height is the most reliable measurement for clothing — waist and chest can vary significantly by body type.

Frequently asked questions

How do I measure my child's shoe size at home?

Place your child's foot on a sheet of paper in the afternoon (feet expand slightly during the day), trace around it keeping the pencil vertical, and measure from heel to the longest toe. Add 0.8–1 cm for growing room, then match to the brand charts above.

Do Nike kids sizes run true to size?

Nike kids footwear generally runs true to size, but we recommend sizing up half a US size for children whose feet are growing quickly, or for shoes worn with thick sports socks. If your child is between sizes, go up.

What is the difference between PS and GS sizing?

PS (Pre-School) covers roughly ages 4–7, typically US 10.5C–3Y. GS (Grade School) starts at US 3.5Y and goes to 7Y, covering ages 7–14. The GS range carries far more styles and colourways — it's the sweet spot for most kids at Rookie.

Are Levi's kids jeans true to size?

Levi's kids denim runs slim, especially through the waist. For a comfortable fit — particularly the 511 Slim and 510 Skinny — size up one. The Bearhug collection has an adjustable waistband so it's more forgiving between sizes.

Can I return or exchange if the size is wrong?

Yes — Rookie Kids accepts exchanges on unworn items with tags attached. Check our full returns policy on the website, or reach out via our contact page and our team will help.

How often should I re-measure my child?

Children's feet can grow up to 2 cm per year between ages 4–12. We recommend remeasuring every 3 months for younger children (4–8) and every 6 months for older kids (8–16).
