Size Guide
How to measure your child for school clothing
Measure once, order with confidence
Taking measurements
- Height: child stands straight against a wall, in socks, no shoes. Mark where a book held flat on their head meets the wall, then measure floor to mark.
- Chest/bust: arms out to the sides, measure over underwear at the fullest part of the chest/bust. Tape should be snug, not tight.
- Waist: measure around the body underneath the tummy, where the waistband will actually sit, not at the narrowest part higher up. This is the measurement to buy to. If your child does wear their trousers on the natural waist, measure there instead.
- Seat/hips: measure over underwear at the fullest part of the seat/hips, snug but not tight.
- Inseam: legs slightly apart, in socks, no shoes. Measure from the crotch down the leg to where you'd like the trousers or shorts to finish.
We'd always recommend buying against your child's actual measurements rather than age, because every child grows at their own pace. Stuck? Call us on 01242 285999 or email us and we'll help you find the right fit.
