Kidswear Shopping Guide: Durable, Safe Fabrics & Size Charts
Size children's clothes by height and chest measurement rather than age, because sizes vary widely between brands and children grow at different rates. Choose soft, breathable cotton for everyday wear, avoid scratchy embellishments near the skin, and buy one size up for fast-growing toddlers when the fit allows.

Why age labels mislead
A '4–5 years' label from one brand can fit very differently from another, and international brands often size by height in centimetres. Measuring your child takes a minute and avoids most returns.
| Typical label | Approximate height |
|---|---|
| 2–3 years | 92–98 cm |
| 3–4 years | 98–104 cm |
| 4–5 years | 104–110 cm |
| 5–6 years | 110–116 cm |
| 7–8 years | 122–128 cm |
| 9–10 years | 134–140 cm |
Choosing fabrics for children
- 100% cotton or cotton jersey for daily wear and sleep.
- A little elastane helps leggings and trousers keep shape.
- Avoid rough sequins, beads and stiff embroidery inside garments.
- Organic cotton can be gentler for sensitive skin, though certification claims should be checked.
- Flat seams and tag-free labels reduce irritation.
Safety checks
- 1
Small parts
Buttons and decorations should be firmly attached for younger children.
- 2
Drawstrings
Avoid cords around the neck and hood on young children's clothing.
- 3
Dyes
Wash new clothes before first wear to remove excess dye and finishes.
- 4
Nightwear
Choose children's sleepwear that complies with your country's flammability and fit requirements; follow its safety labels.
Buying for growth
For toddlers, buying one size up with adjustable waists or roll-up cuffs stretches the wear time. For school uniforms and special-occasion outfits, buy close to the date to avoid outgrowing.
