Size & Fit
Brands don't agree on what "Age 4" means. We do our best to translate.
We curate kidswear for children aged 2 to 8. Most of our brands produce in those sizes. A few have natural ceilings or floors, and where they do, we tell you.
The Fit Guide Rating
Every product page carries a rating between 1 and 5. It tells you how that brand's sizes compare to standard UK age expectations.
| Rating | What it means |
|---|---|
| 1 | Runs very small. Size up by one. |
| 2 | Snug fit. Size up if you want roomier. |
| 3 | True to size. Order your child's usual age. |
| 4 | Runs large. Consider sizing down if between ages. |
| 5 | Runs very large. Size down by one. |

How to measure your child
Height. Standing against a wall, no shoes, heels touching. Mark the top of their head and measure from the floor.
Chest. Around the fullest part, usually just under the armpits. Snug but not tight.
Waist. Around the natural waistline, just above the hipbone. Looser than the chest.
Height is usually the most reliable guide. Some brands publish garment measurements rather than body measurements, and each chart says which.
If it doesn't fit
Kids grow at their own pace and brands don't always agree on what "Age 4" means. If something arrives and it's the wrong size, we'll exchange it. Get in touch within 45 days of delivery and we'll sort it.
