I've written a 5,000 word essay on a topic of my choosing.
While reading through my writing, my teacher suggested I justify my text, as opposed to left-aligning it, as this looks neater.
I agree, finding it looks much better; however, after looking around, many people stated that the justification of text makes it much harder to read. Also, most of the sources I consulted, as part of research, used left-aligned text.
Is it just a subjective matter, or is there a standard?
