Is it even possible to calculate the midpoint of a sheet taking into account margins, row heights, font sizes, and anything else that could affect it

I am trying to place a graphic (a text box) at the left edge (horizontal) and center of the page (vertical) using VBA. The sheets I have to work with use all different font sizes, margins, row heights, etc. It seems impossible to do.

Have I found a limit in VBA

If you can accurately calculate this, please, pleasE, pleaSE, pleASE, plEASE, pLEASE, PLEASE post your code so I can solve this mystery.

Thanks much in advance for your assistance
