It appears that the icons in your SharePoint document library are displaying in a larger size than usual on the site page. This could be due to a change in the display settings or a bug. To resolve this issue, you can try clearing your browser cache and refreshing the page. If that doesn't work, you can try changing the view settings for the document library.
To change the view settings, go to the document library and click on the "View" tab. From there, select "Current View" and then "Modify View". In the "Columns" section, make sure that "Thumbnail" is selected and adjust the "Thumbnail size" to your desired size.
If the issue persists, you can try using a different browser or device to see if the issue is isolated to your current setup.
