Small font

Had been using Scrivener for windows and recently switched to using the iPad version. One of my projects has suddenly become very small print. I must have done something but can not figure out what. Other projects are fine and have looked at setting and they seem to be the same for both projects. Any idea what I did and how to correct?

Thanks in advance

Try using the “zoom” gesture on the text, like you would with a map. Sounds like you changed the magnification on accident.

Thanks for some reason before the two finger feature did not work.
