Has there been an update to the dimensions of the teams backgrounds? March 13, 2025

We are trying to upload 1920 x 1080 custom backgrounds and we are getting an error message saying invalid size. Testing other sizes, anything square 1:1 works but gets cropped in the viewer. We also tried 1280 x 800, but same gets cropped. There isn't mention of this update in any of the update logs. What is the correct size, is there a template to follow to know what gets cropped?

    Thanks for this tip!

    I was able to use images with a width of up to 1800px width (height of 1013px in 16:9) – because 1801px was 1px too much ;-)

    And it doesn't matter whether JPG or PNG.

    Maybe only for me:

    The imported background images are saved in this directory (thanks to @Martin Le Blanc in this thread):

    %userprofile%\AppData\Local\Packages\MSTeams_8wekyb3d8bbwe\LocalCache\Microsoft\MSTeams

    Manually copied images were ignored (but maybe I should have restarted "more than just" Teams?)

    We tried all these workarounds but the only thing that has worked was to reduce the size of the original images to 1800x1012px. Then Teams will let you upload them. Smaller works too, as long as they are in 16:9 format.

    Unfortunately, avoiding Teams seems to be the solution that works for me...

    Indeed! At least I have the support call written response to show that Microsoft knows that it is an issue.

    Agreed, downgrading to an older version should not be a fix. With our environment and patching regularly with thousands of computers; it doesn't work for us. Microsoft needs to fix the bug.
