Impact of Screen Width on Land Visibility

When I resize the browser window by changing only the width, the amount of land displayed on the screen seems to change significantly.

I’m curious about why this happens. Is it related to the camera’s field of view or the aspect ratio? I’d love to understand the mechanics behind this behavior better.

Hi @Mehmed ,
Thanks for your post.
Here are 2 threads related to your inquiry.
The first describes at a high level how Cesium picks optimal zoom level zoom level depends on viewport size?
And the second explains methods to modify this when using the library
Fixed Zoom Level for Different Screen Widths

I hope these are useful for your question. If not, happy to try to provider more explanation or resources.
Thanks,
Luke
