This question already has an answer here:
I am currently reviewing the usability of some internal reports. One thing which strikes me as odd is that all the text is centered. I always prefer left-aligned text.
But apart from my personal opinion (and also apart from design aspects): is left-aligned text preferable from a usability standpoint? (left-to-right text direction assumed).
I can imagine that the eye needs to do more work with centered text (looking for the start of the next line), but I can't find any sources to support this thesis.
