Font size is changing

I set the font size of body and header typography, but sometimes it is changed and the font size becomes much smaller on the page, but not in the settings.
If I enter to the admin site and refresh that page, the font size will be normal again. But later it will shrink again.
Why is this happening?

Thanks for the answer!

Maybe you zoom the view of the page on the browser.
Try to Click Ctrl+0 to reset the view and check the result.

No, I didn’t zoom the view of the page. It must be something else.

:slight_smile: I just guess as per my personal experience.

If not, you may need to provide the theme/template name, a demo URL…
Or it’s the best to ask the author who you bought that item from.
