I am preparing for a conference presentation in which I will talk about giving users options to modify the presentation of text in a UI.
I want to talk about what range of options they should have within a given aspect of typography (i.e. how large and how small should you allow users to make type), but I would also like to talk about how fine tuned those options should be (i.e. does pressing an "increase font size button" increase it by 2 points or 3), but I am not sure how to say this in a succinct way.
Does "gradient" or "how gradated options/ranges are" make sense?
