I'm running Blender 2.77 on a MacBook Air with OSX 10.11.6 with just the built-in keyboard and trackpad (I mostly script stuff). When I type Ctrl++ it doesn't make the font in the Python console larger, it just shows a string of "===". I've tried all kinds of other two and three-key combinations, but the font never gets bigger.

I'll give a talk introducing Blender scripting to some Python programmers, and I'd really like them to see what's going on there. I'll take any kind of work-around that makes the text bigger without chaning the Python console window size edit: or changing the font size in all the windows at the same time.

I looked around in preferences and couldn't find an explicit font size for the Python console, but there may be some keyboard mapping I can do?

I bought the computer in the far east and it types in Traditional Chinese as well - I don't know if that influences the settings. Another person with same situation here (MacBook Air, OSX, Chinese Keyboard, Blender) had no problem with it.

If you follow the way blender stores the screen layout you will find the space used by the console has a font_size property, setting that will get the result you want.

A small script is easier than finding it manually.

import bpy

for a in bpy.context.screen.areas:
    if a.type == 'CONSOLE':
        a.spaces[0].font_size = 16

Alternatively for the current console, keep in mind bpy.context is by default aliased as C:

# repeatedly execute until satisfied
C.space_data.font_size += 1

  • $\begingroup$ yippie yay yay for Python OK! OK this is a really helpful introduction to screen areas, and it will be a simple but compelling example in my basic talk. Thank you! $\endgroup$

In the help text it says: "Zoom: Ctrl +/-, Ctrl-Wheel" I see you tried ctrl +/-, but try the scroll wheel.

So, with the mouse hovering over the console pane, hold down ctrl and scroll with the middle mouse button to resize.

  • $\begingroup$ Thanks, but if you read the question you will see I do not have a scroll wheel. I have no problem doing anything else in Blender with my track pad, but I can't believe that a font size in a Python window exclusively for typing and reading text would be the one window that requires me to go out and invest in a 3-button mouse!! That would be ironic considering I've never needed nor used a mouse with Blender! $\endgroup$

    $\begingroup$ @uhoh Can't you scroll with a touchpad? $\endgroup$

    $\begingroup$ If there is something scrollable and the cursor is over it, two fingers scrolls. But I don't have a hard-wired, dedicated scroll wheel. If the cursor is over the Python console, then two fingers scrolls up and down. It looks like this: youtube.com/watch?v=9wyVwZUuKOw $\endgroup$

Go to user preferences

Look at the DPI setting in system, under general

  • $\begingroup$ OK got it (in my version it's called System not general). But it's a global thing and makes the UI look ridiculously crammed and cartoonish. I'll consider it, but I really need something that only affects the Python console. Thanks! $\endgroup$

  • $\begingroup$ I like this answer, but I see you don't want it to effect everything. So try: With the mouse hovering over the console pane, hold down ctrl and scroll with the middle mouse button to resize. $\endgroup$

  • $\begingroup$ Thanks @10Replies but I've already given one of these in the same room and I know just what I need. I need that text to be bigger without screwing up the whole thing. The scripting window has a nice font size control right there, but I'd like to show and use the interactive Python console as well. $\endgroup$
