I see that under display there are two options, 100% or 200%. I would like something in-between say 125%. Is this possible?

Hello, Sibbie & welcome to LQ.

We are volunteers trying to help you with the information you gave us. You gave us nothing.....

That said, some terminal programs allow zooming or changing the font size. Others don't change fonts at all. If you don't like your terminal program, change it.

If you want to change text size in the consoles outside of X, the fonts are in /usr/share/kbd/consolefonts. Most top out at 16pts. But there's the 'terminus' console fonts which go up to 32pts. So I have 'setfont ter-928n' run ast startup which sets a 28pt font.

If we knew something more than just "Mint", and your wanting something "in-between", we might be able to offer useful help. Start by pasting input/output here, using code tags, from an X terminal running command inxi -GSaz --vs. If a command not found message results, install inxi with sudo apt, or equivalent GUI tool.

You can also use the ctrl + to zoom in on text and ctrl - key combinations to zoom in and out on text.

Sibbie, yes there are other possibilities like 125%
Open System Settings -> Display
The top middle of Display you will see Settings
In settings enable the "Enable Fractional scaling controls (experimental)
Then at the top middle select Layout
You should now see more to select under the Monitor scale

Another fix would be to go to System Settings -> Font Selection
Increase the Text scaling factor from 1.0 to something like 1.2 or what ever looks best for you.

Not all apps will scale right, and sometimes you gotta edit config files or set environment variables yourself, etc.

GTK2 50%/100%/200% Only (But this is basically EOL, very few apps in mint repos use that, mainly hexchat and gimp).
GTK3 50%/100%/200% Only
GTK4.14+ Allows Fractional Scaling

QT4 Nope, but also basically EOL, very few apps in mint repos use it, mainly VLC.
QT5.6+ Allows Fractional Scaling
QT6 Allows Fractional Scaling

Elementary apps all allow fractional scaling
