Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi, chelle99
In Microsoft 365, comparing the visual size of fonts at the same font size is usually determined by the design of the font. General:
Some fonts such as Arial Narrow or other compactly designed fonts usually appear smaller at the same size.
Fonts such as Impact or Arial Black and some decorative fonts usually appear larger at the same size.
These differences stem from the letter widths, letter heights, and overall design style of the fonts. Specific minimum and maximum fonts may vary depending on updates and font libraries. For an accurate comparison, you can type the same size text in a text editor and make a visual observation or use some specialized software to take measurements.
I hope the above information can help you. Feel free to send a message if you need further help.
Best wishes
