Hello so im making a leveling gui and the bordersize pixel looks way different on mobile than pc

Pc:

Mobile:

sorry, the image is a little small for mobile, idk how to fix that, but zoom in or something and youll see it. How do I fix that?

If you cant see it, in the photo the frame borders are overlaping the rest of the frames bc they are sized wierd

Try using the {x, 0, x, 0} slots

0.2 = 20% of the width/height of the screen

the size of the UI changes when screen size changes
