Technically, the cut-off is 1048576 bytes right now (that's the amount I set in $MAX_POST_LENGTH, a global variable in Rockets) however I will probably be increasing this value to account for file uploads, etc.
PHP typically has a 16 MB limit, set in php.ini. It prevents people from uploading movies and giant files and things that tends to slow down the server for other users.
