Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hello Susan,
Thank you for posting to the Microsoft community.
I understand you want to be able to increase the size of the font in Teams display. I'll be providing answer to your request.
To increase the font-size of your Microsoft Teams display, go to your Microsoft Teams account, click on your profile picture in the top right corner, select the three horizontal dots (...) next to your profile picture. In the menu, select Zoom and then use + and - buttons to increase or decrease the display size.
You will be able to adjust the overall display size which include the font size, making it easier to read.
Hope this helps, and let me know if you need further assistance.
Best Regards,
Favour | Microsoft Community Support Specialist
