This might work. Match means error.

/.{251}/s

there's no need to use an expensive regular expression

just use length property for strings, e.g.

var s = "abcd...xyz";
console.log(s.length)

and, just to answer the question, the regular expression would be 

if (!(/^.{,250}/).test(s)) { /* error */ }
