Consider the two plots
{
Plot[x, {x, 0, 100}, Axes -> False,
Frame -> {True, True, True, True},
FrameTicks -> {{None, All}, {All, None}}, AspectRatio -> 5/16,
ImageSize -> {600, Automatic}]
,
Plot[x^2, {x, 0, 100}, Axes -> False,
Frame -> {True, True, True, True},
FrameTicks -> {{None, All}, {All, None}}, AspectRatio -> 5/16,
ImageSize -> {600, Automatic}]
}
I would like both of them to appear perfectly one above the other with exactly the same x-axis lengths, starting and ending at the same x-axis-pixel locations respectively on my screen. How can I do this?

ImagePaddingis exactly what I needed, thanks! – Kagaratsch Jun 23 '18 at 15:49
