Chat, Changing font size

You can control the size of chat fonts in the client settings under the Accessibility tab. 

1. Sign in to the Zoom desktop client.
2. Click your profile picture, then click Settings.
3. Click on the Accessibility tab. 
4. Chat Display Size is what you want to adjust. 

Hope that helps and please make sure to mark the solution as accepted if this information is what you needed.

Thank you for your response; however,

"Chat Display Size is what you want to adjust. " does NOT show up. Could be that I have Windows 11 so the instructions are different?

I don't see the accessibility option, and pressing control and plus do not work. Thanks!

Zoom Desktop. Ubuntu 20.04 LTS.  Zoom Desktop menu - "Accessibility".  As you can see the existed  options can't give the ability to change the text size for Chat window at all.

Does exists any hided/secret tricks or keyboard combinations?
Thanks.

I Just hosted a meeting and while in Chat, I hit "Control and the - (minus sign as I was at 180%) and VOILA!!! I was able to keep hitting the minus sign down to 100%. I hope this works for those like me who did not find the "Accessibility' link.

It worked a treat - many thanks 

The thing that confused me is that I need to hit shift to get the + sign, but not to enlarge the font. So, it's actually "Ctrl =" to enlarge the font and "Ctrl -" to shrink it.

I want to make the default font size smaller. But the only smaller size is 80%, which is a tad too small. The font size of the rest of the UI text is just right. It's probably a 90%. Can we have that option?

I'll give this a try.  My chat was huge in a meeting today so I couldn't read the messages coming through without cutting and pasting them into a doc - which was inconvenient to say the least.  I don't have an accessibility tab either.  I will try control -  tomorrow and hope it works!
