Decathlon size guide

Official chart in centimetres: women, men, kids and baby.

Official source: Decathlon — recorded on September 23, 2026

About this chart

  • Decathlon publishes a single general chart, with no split by brand or sport.
  • For women's and men's clothing, Decathlon publishes two charts that split sizes differently: the women's L covers a 96–103 cm bust in the letter chart, but 100–103 cm in the detailed chart, where 96–99 cm is M-L. If you know your French size, go by the detailed chart.

Bras — band and cup

For styles with a back fastening, a neighbouring size can work: with one cup size up, take one band size down, and vice versa. A 95C can therefore wear a 100B (fastened tighter) or a 90D (fastened looser).
