Question Help with scaling between devices

Hi all,

I am working on some UI, and need to have it scale correctly between different devices. I thought it would be a simple case of changing anchors and sizing, but no matter what I try, I can't get the effect I wanted.

Is there any way I can achieve this with the built in tools within Unity?

Thanks
