How to get terminal size or font size in pixels?

Question

I\'ve seen some posts and answers about how to get the terminal size in numbers of columns and rows. Can I get the terminal size, or equivalently, the size of the font used

Answer 1

Another possible approach, with limited support, is checking the ws_xpixel and ws_ypixel values of struct terminfo.

A python snippet to query these values:

import array, fcntl, termios
buf = array.array('H', [0, 0, 0, 0])
fcntl.ioctl(1, termios.TIOCGWINSZ, buf)
print(buf[2], buf[3])

This only works in certain terminal emulators, others always report 0 0. See e.g. the VTE feature request to set these fields for a support matrix.
