How To Change GameObject Position Base On Screen Size?

Hello everyone, i’m trying to change my game object’s position base on screen size, but i still cannot figure out how to do that, here is an example:

as you can see i have some circles on the screen in 1334x750, and when i change the screen size:

The circles changed its position, a circle get inside the screen and i don’t want that, i want all gameobjects stay at the same place like the screen in 1334x750, thank you for reading.

do not use fixed scale of the screen, use 16:9 ratio or an other aspect ratio, this will solve this issue
