Getting the most from kids sizing
Conversion tables translate one label into another, but they cannot account for how a specific brand drafts its patterns. Use a converter to narrow the range, then compare the result against the product's own measurement chart before ordering.
Keep a written record of your key measurements in centimetres. With those numbers, any chart in any region becomes readable, regardless of which labelling family it uses.
Frequently Asked Questions
Should I buy by age or by height?
Height is far more reliable. Age labels reflect an average child in the brand's home market.
How much growing room should I allow?
One size up is reasonable for outerwear; for everyday clothing an oversized fit can be uncomfortable and unsafe for young children.
