How to obtain string not longer than certain length in R

I have a vector of strings that looks like this

x <- c("WDNTO","WDRN","WDSAX","WECAX","WEN","WEDTO")

What I want to do is to extract only strings not longer than 4 characters, resulting in 

  WDNT,WDRN,WDSA,WECA,WEN,WEDT

What's the way to do it?
