SSMS 2017 Changing font size
I'm using SSMS 2017 and want to make my font larger in the query window. When I go to Tools > Options > Environment > Fonts and Colors > and then change the size of my font and press Ok, nothing changes. The size doesn't get affected in the open query window nor in a new query window.
Solution 1:
This is working solution tested on ssms v18.4.
In OP's case I think you did not restart your ssms.
Also, as in arrow 4 you will need to know what settings you want to change in order for it to work as expect.
It should be very much the same for your ssms version.
Done.
