Size guides and measurement conversion.
Compare your measurements with the product’s official chart before choosing a size. Return costs are worth checking before you order.
Standard
Size names are not universal across brands. Use the official product chart. The unit converter below converts measurements without guessing a clothing or shoe size.
Use the official brand chart for the exact product; a universal size conversion is not reliable.

This converts units only; it does not predict fit.
Check the product’s own chart
Where a shop publishes its own chart, that chart wins over ours. Brands drift from the standard, and they drift by model rather than by label: the same brand can run true in one shoe and half a size long in another.
Measure carefully and follow the brand’s instructions for the specific product. Fit depends on model, width and cut; there is no universal rule to size up or down.
Brand-specific charts and product instructions take priority over general references. Use tables as a starting point and confirm the current product chart before buying.
