Hello, i need a help, how to make those ImageButtons fit on small screen devices?

1st picture - how it should be

Use scale for sizing UI in most cases not offset, and to keep it a square you can add a “UIAspectRatioConstraint” into it.
Use scale for UI sizing, not offset (most of the time). You should also use UIAspectRatioConstraint. I’d recommend installing a plugin such as AutoScale Lite - Roblox or AutoScale Plus - Roblox. Autoscale Plus provides full automation and it’s only 50 robux. The lite version works fine too.
