After installing Matter in Microsoft Teams and pinning the home tab, we'd recommend customizing the appearance to represent your company's brand and style. You can customize the following items:
Workspace Avatar: Square 272x272px images work best.
Workspace Cover Photo: 1096x242px images with a transparent background work best.
Workspace Wallpaper: Max of 512x512px. Choose from the following Fit / Sizing Options:
Cover (Fills the screen while maintaining aspect ratio)
Stretch (Forces the image to fit, even if it distorts)
Fit to Screen (Ensures the whole image is visible, may add padding)
Tile (Repeats the image)
How to Customize the Matter Home Tab
Go to the Matter Home Tab, located on the far left navigation bar.
Go to Admin Tools > Customize Appearance.
Upload the respective file, respecting the specification limits, and click the Save button to confirm your changes.
