Choose their size in three simple steps
- Start with the size they wear now. Use the age band on this item. M means months; T and Y mean years.
- Allow for the outfit. Coats need room for a jumper; daytime one-pieces need room through the torso and nappy.
- Choose the fit they need. For ordinary daytime clothing between two age bands, the larger band usually gives more room. Sleepwear and footwear need a secure fit, so do not size up automatically.
Read the label
| Example size label | What it means |
|---|---|
| 3–6M | Approximate age: 3–6 months |
| 18M | Approximate age: around 18 months |
| 2–3Y / 2–3T | Approximate age: 2–3 years |
| 73 (3 to 6M) | Supplier code 73, with the supplier’s 3–6 month age guidance |
| 80cm / 80 | Commonly a height-style clothing label, approximately 80cm child height. This generic interpretation is not supplier-verified. |
These are general guides, not measured garment dimensions. There is no single sizing standard across suppliers, and children of the same age can need different sizes.
Coats & jackets
Allow room for the jumper underneath. The front should fasten without pulling, and sleeves should reach the wrists without covering the hands. Between two age bands, the larger usually works better for a daytime outer layer.
Cardigans & jumpers
Start with their usual age band. Cardigan buttons should close comfortably without pulling across the chest. Cuffs should sit near the wrists. For a relaxed daytime layer, choose the larger of two age bands.
Trousers, leggings & shorts
The waist should sit comfortably without digging in, with room to bend and sit. Check leg length as well as waist fit, and allow room through the seat for nappies.
Rompers & daytime one-pieces
Allow room through the torso and nappy. Shoulders and crotch should not pull when your child sits or stretches. A taller child may need the larger of two age bands even when the waist fits the smaller one.
Dresses & skirts
Choose comfortable room at the chest or waistband and a length that leaves them free to walk, sit and play.
Shoes & boots
Measure both feet from heel to longest toe while standing, wearing the socks they will use. Use the longer foot. An age label is not a reliable substitute for foot length; numeric shoe labels are not centimetres.
How to measure
- Height: Measure from the top of the head to the heel, without shoes.
- Chest: Measure around the fullest part, with the tape level and comfortably loose.
- Waist: Measure around the natural waist without pulling the tape tight.
- Compare a garment: Lay a well-fitting item flat. Chest width is armpit to armpit; length is shoulder to hem; sleeve length is shoulder seam to cuff.
Body measurements and flat garment measurements are different. For example, a flat chest width is not a chest circumference. We do not present generic centimetre charts as verified measurements of our products.
