Getting the most from sports 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 activewear fit tighter?
Compression pieces are drafted smaller intentionally. Check whether the brand lists the garment as compression, athletic or relaxed fit.
Do running shoes need a different size?
Many runners go up half a size to allow for foot swelling over distance.
