Font on my iPhone 10 is suddenly huge when I open new documents/projects

I love writing on my iphone when I have an inspiration. All of a sudden, new projects or new pages/drafts are using a large font. It seems I can control some of the font size with the accessibility setting, but I want the small font back! Help please!?
Thank you!

Is it actually the font, or the zoom setting? Pinch/spread your fingers on the screen to change the zoom.
