I would like to locate the exact position of the north west corner of the text area. Using layout (see image in Notes section), it seems that the required offset from current page.north west is

xshift=1.0in+hoffset+oddsidemargin,

yshift=-1.0in-voffset-headsep,

Using showframe package: (as in MWE)

The image below is the north west corner of the text area at 6400% zoom where I have placed a gray + and a filled in circle. This visually looks like it is pretty close to the correct location. However, to get to this position required an additional tweak of

(-0.35pt,2.35pt)%% Required shift to obtain image below (see MWE)

from the above parameters.

The somewhat related questions listed in the References section mention an issue with inner sep and parindent, both of which have been accounted for. (They are actually not needed here, but added them anyway).

Why is this additional tweak required?

Using showframe option to geometry package:

IF instead of using the showframe package, I instead use

usepackage[showframe]{geometry}

The tweak required is slightly different:

(-0.1pt,1.8pt)

which yields:

References:

• 
  TikZ: Anchor current page north west isn't where expected.


• 
  TikZ current page.north west shifted ~4pts?.

Notes:

  Using layout, we obtain the following picture from which I obtained the parameters to compute the exact location of the north west of the text area.

  
  
  

  

  
  
  

  

  
  

Code:

documentclass{article}

usepackage{showframe}

usepackage{tikz}



usepackage{layout}

usepackage{geometry}



newcommand*{ShowNorthWestOfTextArea}{%

begin{tikzpicture}[remember picture, overlay]

    coordinate (X) at ([

            xshift=1.0in+hoffset+oddsidemargin-0.35pt,

            yshift=-1.0in-voffset-headsep+2.35pt,

        ]current page.north west);



    draw [draw=red, fill=yellow, text=gray] (X) circle (1pt)

        node [inner sep=0pt] {+};

end{tikzpicture}%

}%





begin{document}%layout% <-- uncomment to obtain the layout parameters
