(I am a student in the TypeWest program so please forgive any basic questions.)
I have a question about metrics: Should the ascenders/descenders match the metrics we are using? For example: If my Ascender metric is 800, should the stem of the “b” touch/reach the 800 position?
I’ve seen various typefaces use different types of alignment and I’ve made my findings into a diagram below. You can right-click and "Open Image in New Tab" to make the image bigger.
I’d love to know about best practices since not “reaching” the metric value leaves more space. Let me know if this question is confusing and I can try to clarify.
(I am using a 1000 UPM grid by the way.)
