How do I enlarge speaker picture

The speaker picture size is based on the resolution of the picture and how large the user's window is during the meeting.  There is no way to force a speaker picture to be larger on everyone's screens.

As a  teacher on Zoom, I totally agree that having my speaker picture larger at times would be very useful.

Hello,

You can achieve this by using Multi-speaker video layout.

The Multi-speaker video layout helps provide meeting participants a more engaging experience, dynamically adapting to current speakers by highlighting and enlarging their video tiles over others, while still providing a view of other participants in a smaller gallery view below. This will also be available when viewing shared content in side-by-side mode, with the speakers being more prominently displayed next to the shared screen or app window.
