You don’t need to use a specific device. You can have it all on devices and look just as nice. Simply, you have to scale the gui relative to the screen size by changing the scale. I recommend to use this plugin and look into the tutorial. [Plugin] AutoScale Lite for GUIs - Scale your UI “Scale” is the percentage of the screen size. Each gui’s size or position consists of 4 numbers. If you want to scale it further to fit a specific ratio, you would have to use UIAspectRatioContraint. You can learn more about that here, UIAspectRatioConstraint | Documentation - Roblox Creator Hub
