How many pol is that device?

[vinians]

I want to scale the font correctly in a bunch of devices, so I want to know how to determine the size in inches of the diagonal of the screen?

Try this code:

Sub GetDevicePhysicalSize As Float
    Dim lv As LayoutValues
    lv = GetDeviceLayoutValues
    Return Sqrt(Power(lv.Height / lv.Scale / 160, 2) + Power(lv.Width / lv.Scale / 160, 2))
End Sub

Best regards.

You can also use the new property:

Log(GetDeviceLayoutValues.ApproximateScreenSize)

However I recommend you to use AutoScaleAll instead:
