Accessibility Text Size Option ?

[aria]

I am thinking of getting a Mac this year but have never used one..
I was recently viewing a video on the Apple site demonstrating some of the accessibility features
'for visually impaired users.

It mentioned that you could increase the text size in increments at 2, 4, 6, 8, etc.

Does anyone know if you can increase text in smaller increments as in, 2.5, 3, 3.5, 4, 4.5, etc?

I am asking because a size 2 would be too small for me to see and a size 4 too large.
I currently use a screen reader, Zoomtext, at 2.5 and 3 size.

Thanks

A number of Apple Apps have the ability to adjust font on the fly but as to what steps they use, that would take some time to sort.
eg;
