It may be possible that you may have a problem with your server settings that are causing you the maximum size errors. 

Exceeding the uploaded file size is a widespread problem that can be eliminated easily and without much effort.

This is the limit set for a single file to be uploaded on WordPress. Though WordPress comes with various maximum file sizes, mostly 64MB but may vary sometimes.
