How many cookies do browsers support?

Question

Browsers

Greetings
I tried to find reliable information on the network about the amount of cookies supported by browsers, but somewhere they write that only 4 kb are supported, somewhere - 20 kb, but how are things really - is there reliable information on browsers?

Answer 1

but how are things really going - is there reliable information on browsers?

But in fact, there are tests, for example, this one , as well as common sense, which suggests that the cookie size > 4Kb - in the vast majority of cases, it indicates serious developer errors.
