Here are the configuration settings for the Terminal app in Yosemite.

enter image description here

It shows that I can set font size to the distinct values given in Terminal. How can I set it to some other in-between value like in my case, I want to set it to "15"?

    My two cents - try iterm2. If there isn't any particular reason for sticking to Terminal - use iterm2.

Here is what I did in OS X Yosemite 10.10.4.

Terminal (menu) > Preferences... > Settings > Select the target Profile > Text > Change... (button)

This brought up the Fonts window shown in the image below.


I then resized the Fonts dialog box vertically until the Size text window appeared and entered 15, as shown in the image below.

    It would be lovely if there were a way to do it from the command line

You can also add custom values for font sizes. From the Font window, click the gear in the upper left, and choose "Edit Sizes".

Then, enter your value.

    This should now be the accepted answer, as you cannot do the currently accepted answer anymore.

    Both answers worked for me in 2022 with Monterey (macOS Version 12.3.1)

Optionally, you can increase and decrease font size for bash with,

Command and the Plus (+) key
Command and the Minus (-) key

On Ventura 13.3.1, there was no slider. I needed to add a new, discrete size.

"Edit Sizes" setting "New Size"
