几年前是4K，不过现代浏览器都相应提升了吧，不同浏览器的规则不同

Practical user agent implementations have limits on the number and
size of cookies that they can store. General-use user agents SHOULD provide each of the following minimum capabilities: o At least 4096 bytes per cookie (as measured by the sum of the length of the cookie's name, value, and attributes). o At least 50 cookies per domain. o At least 3000 cookies total. RFC6265: HTTP State Management Mechanism http://tools.ietf.org/html/rfc6265 这里说的是SHOULD，因此你不能断定某些脑残浏览器会怎么定义自己的策略。不过按照这个标准执行不会错，忽略那些浏览器就好。 |
