Jewellery sizes can vary depending on the type and style, but for rings, the most common sizes range between M and O for women, and Q to T for men. For bracelets and necklaces, lengths often range from 18cm to 21cm for bracelets and 40cm to 60cm for necklaces. However, jewellery should be chosen based on personal fit and preference, which is why it's important to try on different sizes or consult a size guide.
