I am trying to change the tk widgets to ttk, so I can globally correct them,
e.g.
root=tk.Tk()
sb=ttk.Scrollbar(root)
sb.pack(side=tk.RIGHT,fill=tk.Y)
style=ttk.Style()
style.configure("TScrollbar", width="10m")
However the width doesn't apply on the up/downarrows which they remain tiny.
Where I can find the style options that I can change?
I've tried
style.configure("TScrollbar.uparrow", width="10m")
but doesn't work

Thank you all for the suggestions.
I am going to try them.
It would have been nice it tk had a global option to rescale everything by x2
Like in XFCE window manager

If you want to relate your screen distances to the size of characters in a
font, then you could use font's `measure` method to compute pixel distances for
em-s:

Recently I've got a 4k laptop, and the first experience with linux and the 4k
display is quite painful.
I am still trying to tune it but for the moment my tkinter applications do not
render nicely on such a display.
- all widths like borderwidths, decorations, separators etc, set in pixels do
not scale with the dpi settings. Could we use "mm" for their settings instead?
- checkbox, radiobox the indicator appears tiny wrt the text
Is there a way to detect from tkinter a high res display and force a window
scaling x2 for everything?
What is your experience with such displays?
