Change the standard size of a checkbox (scripting)

Its it possible to determine in a script, the size of a checkbox?

They’re usually sized for you in the dialog editor. What are you trying to do?

I'm just trying to open the checkbox with a larger view without everytime resizing it myself...

The size of the checkbox itself (as in the square with a tick inside it) can't be changed. It always draws at the standard size (scaled to the system's DPI).
