This might help a bit:

	| f |
	((1 to: 30) collect: [ :n |
		f _ StrikeFont familyName: #NewYork size: n.
		{
			n.
			f pointSize.
			f height.
			f ascent.
			f descent.
			f.
		}
	]) explore.

#familyName:size: answers the smallest font at least n pixels in height, so you get the same "pointSize = 18" font when you ask for sizes 21 through 25. Note that this font has three pixels of leading, so the overall height of 21 is really 18 pixels of character data + 3 pixels of leading. 

Cheers,
