How do I make an image label converted to scale size so it's the same for all devices?

I have an image label under a Scrolling Frame, but somehow I just can't get it to scale size, meaning the same size on all devices.

I used multiple scaling plugins, but they all seem to fail. My other guis are scaled fine, it's just this image label under Scrolling Frame I can't get the right size.

Image label size: {1.2, 0},{1.5, 0}

Image label position: {-0.083, 0},{-0.303, 0}

ZIndex: 1

ScaleType: Fit

Anchor point: 0,0

do you mean you want it to fit the screen? if so put 0 in each setting

{1, 0},{1, 0}
