What’s the Difference Between a Font and a Typeface?
This is where we get the terms typeface and font. In the example above, Garamond would be the typeface: It described all of the thousands of metal blocks a printer might have on hand and which had been designed with the same basic design principles. But a font was something else entirely. A font described a subset of blocks in that very typeface--but each font embodied a particular size and weight. For example, bolded Garamond in 12 point was considered a different font than normal Garamond in 8 point, and italicized Times New Roman at 24 point would be considered a different font than italicized Times New Roman at 28 point.
