Nonpareil, Minion, Brevier, Long Primer, Pica, English, Columbian, Paragon....and others.

Basically, it went like this 3,4,5,6,7,8,9,10,11,12,14,16,18,20,22,24,28 until 30 points, after that, it was mostly wood type.

Moveble Type existed before the era of international standardization so specific agreed upon standards did not exist at the outset. Standards eventually came into being once printing became more widespread and foundries started to sell type but still varied amongst regions. Hence arcane names such as Brevier, Nonpareil, etc. did not necessarily translate from one place to the next.

Maybe so, but generally speaking, in the twentieth century, it was a little more limited than that. At least in my experience. The common sizes included 6, 8, 10, 12, 14, 18, 24, 30, 36, 48, 60, and 72...all available in lead.

I happen to have some 16 pt and 54 pt type, but I wouldn’t consider them common.

This is good to keep in mind if you’re designing a publication that is supposed to have a retro or throw-back feel.

21.5 pt type? No such thing!
