Resizing the chat list
You can change the size of your chat list to make it easier for you to use.
To resize your chat list:
- At the top of the chat box, click on the drop down arrow next to your profile picture.
- Hover over Most popular to show the menu options.
- Choose the size of your chat list by selecting Tiny, Small, Medium, or Large.
If you'd like to minimize your chat list -- just click the Chat icon at the bottom of the chat box.
You can also turn off the chat list entirely in Gmail. Note: Doing so will sign you out of chat unless you are signed in with another client.
