Mountain Bike Full Face Helmet, Sizing help!?

Im about to buy a full face helmet for mountain biking. Idk what size to get! I wear a 7 3/8 fitted hat, which is 58.7 cm, so that would be my head size. The size chart says that a medium is 57cm, and a large is 58 cm. Idk if i should grab a medium or a large.

If your head is 58.7cm, surely a 57cm is too small?

If I were you I’d go to a shop and try some on. Even if you don’t end up buying it there, at least you know the right size.
