I wish to have an image in my terminal background but I am unsure how big the image needs to be. The terminal is sized at 80x24 which means 80 columns wide and 24 rows high, however I am unable to find anywhere documenting how wide a column itself is. Does anyone happen to know the pixel width of a column/row in the Gnome Terminal?

Don't you want to resize your terminal? I guess the column/row size depends on the fonts you are using. – AlexTheBird Jun 18 '11 at 23:04
No I am happy with my 80x24 size, but those numbers on their own are a useless metric for determining the physical size of the terminal. Without knowing the pixel width of a column it is impossible to know the true width of the terminal. – Peter Jun 18 '11 at 23:12

It's 80x24 characters, so the size depends on the font, e.g. with the 11pt Monospace font it's 722x434 → one character is 9x18px with 1px border around the terminal.

I suggest you make a screenshot of your terminal and determine the size by using the selection tool of GIMP (or go with the easier solution suggested by AlexTheBird - just thought if you want to make a background image, you already have GIMP locked and loaded :-)).

Thanks, exactly what I needed to know. – Peter Jun 18 '11 at 23:20
And in gimp you can zoom the image which makes the selection much easier. – AlexTheBird Jun 19 '11 at 0:53

You could start the gnome screenshot tool. You can find it in "Applications menu -> Accessories -> Take Screenshot".

  1. Select "Select area to grab" hit the "Take Screenshot " button and save the image file.
  2. Right mouse click on the image file you saved and go to tab "image" and et voila ... your image size.

You mean "Grab the current window" and set Effects to not include the window border, right? ;-) Also, you would need to disable the menubar to get the right size. – htorque Jun 19 '11 at 0:11
No, I mean "Select area to grab". Because then you can ... select the area to grab. The area would be the 80x24 Peter mentioned. – AlexTheBird Jun 19 '11 at 0:29
You can select an area of eg. 722x434 pixel-precise? Not bad! – htorque Jun 19 '11 at 0:33
ok ok, maybe it is a little bit hard to select it pixel-precise. :-) – AlexTheBird Jun 19 '11 at 0:37
