Tk 9 uses a different strategy for the scaling-related stuff:  On X11 it
retrieves the display's scaling level (100%, 125%, 150%, ...) from the
system settings, assigns it to the public variable tk::scalingPct, and
passes a value derived from the latter to "tk scaling" (see "man n
tk_scalingPct").  Both $tk::scalingPct and [tk scaling] are used at many
places in the Tk code and library scripts to make the widgets and
standard dialogs scaling-aware.

Out of curiosity:  What is your desktop environment
(GNOME/KDE/Cinnamon/MATE/Xfce)?  What is the display's scaling level?
Are you using Xorg or Wayland?.  What are the values $tk::scalingPct and
[tk scaling] immediately after starting wish?

 In my experience *every* Tk app is far too small for me. For example, I
use gitk but fortunately it lets you set all the fonts. For others I am
able to add in the [tk scaling] if statement or simply can't use them.
 I'm using Tcl/Tk 9.0b2 on Linux 6.1 amd64 Debian/Linux 12 (bookworm) with
Xfce 4.18 (GTK 3.24).
 $ wish9
% puts $tk::scalingPct
100
% puts [tk scaling]
1.3333333333333333
 I don't know if I am using Xorg or Wayland. My display is 1920x1200 (16:10
aspect ratio)

Suggestion:  In the "Fonts" tab of the "Appearance" dialog set the font DPI to 120.  This will increase the size of the fonts by a factor of 1.25, for all applications, including the Tk scripts.  After doing this, right after starting wish, $tk::scalingPct will be 125 and [tk scaling] will be 1.66666666666666666666.  Just give it a try!
