I want to make my font to pay what you want, and i don’t know what licence I need to use for that, & what website for distribuate my font.
Gumroad supports pay what you want.
So licensing will really depend on where and how you sell your fonts. We will try to provide more actionable insights in the future, but you could start on places like Creative Market, which has its own licensing model (most distributors will have their own rules, and different selection criteria): https://creativemarket.com/licenses
Is Gumroad reliable source for selling fonts?
