How do I make a ScrollingFrame fit properly on all devices?

I’ve found a few questions like this here on the DevForum, but none seem to help me. They’re either too complicated (use terms and stuff I don’t know about/how to use) or don’t apply to my situation.

What do you want to achieve?
I want my ScrollingFrame and all the buttons/texts to fit perfectly on all devices.

What is the issue?
When I go and test it it just looks all cramped up or way too far away from each other.

What solutions have you tried so far?
I’ve had people try to help me, I’ve tried using the AutoScale Lite plugin and more, I’ve looked the solution to this up on Google, but I can’t find anything good to help me with it.

Also, something to note is that I’m not a UI designer at all. Please use simple terms lol.
