We don't recommend increase the size of resolution field of knowledge documents. Instead, the following options can be considered for lengthy documents
--some contents of a knowledge document can be in an external file and you can attach the external file as an attachment of the knowledge document. in fact, you could attachment multiple files to a knowledge document and have the resolution field as reference to the attachments to save space
--you could also split big KD into a couple of knowledge documents and use related knowledge tab to "link" them together
