It's much more likely that you're creating websites that fail accessibility guidelines and that many people are forced to zoom in to read.

100%/16px is standard for article body copy.

The intro in the linked article is set with a 24px font size and 960px width. For me, on a good desktop screen, that is uncomfortably large on both counts for a full paragraph of body text.

The main part of the article, set at 18px with about 700px width, is sensible IMHO.
