How accurate are these charts?

Clothing and footwear sizes are nominal labels, not physical units. The tables here follow EN 13402 / ISO 3635 body-measurement bands and ISO 9407 Mondopoint foot lengths, which is what most European and Japanese labels are based on. US and UK retail sizes are conventions and vary by brand, often by a full size.

For the most reliable fit, use the measurement column: measure the body dimension listed above, then match it against the brand's own chart.
