Here’s a quick overview of standard rubber fin straps (used on scuba/snorkel fins), including typical sizes and what “standard” means in this context — plus examples you can buy:

There isn’t a single official global standard for fin strap size — divers rely on common sizes from manufacturers (e.g., ~460 mm length). Some earlier diving equipment standards like DIN 7876 discussed fin dimensions and strap adjustability but have since been withdrawn.
