So I have this Frame with all the Images and stuff and I want to keep their ratio constant, so i put an UIAspectRatio into the Main Frame that handles all the ui objects.
first check your screengui inset settings, see whether you like to preserve some extra space for it to avoid device things such as ‘camera’ and ‘bottom bars’
then you seem to use a fixed aspect ratio (UIAspectRatio), then obviously if you scale fully to the landscape’s device height, it will look exactly like this. because this device has a longer width than your reference
1920/1080 = 1.777
800/360 = 2.222
so if you don’t like this, don’t use a fixed aspect ratio. and then think about which parts in your ui should have larger width, or where do the extra width should go
