Font size is a critical aspect of typography that affects readability, accessibility, and the overall aesthetic of a text. It is typically measured in points, with larger sizes being easier to read from a distance and smaller sizes allowing for more content to fit on a page.

Spacing, or distributed practice, refers to the strategy of spreading out learning over time, which enhances long-term memory retention compared to massed practice or cramming. This approach leverages the psychological spacing effect, where information is more easily recalled when learning sessions are spaced apart rather than concentrated in a short period.
