The point was first established by the Milanese typographer, Francesco Torniella da Novara (c.1490 – 1589) in his 1517 alphabet, L'Alfabeto. The construction of the alphabet is the first based on logical measurement called "Punto," which corresponds to the ninth part of the height of the letters or the thickness of the principal stroke
Notations
A measurement in points can be represented in three different ways. For example, 14 points (1 pica plus 2 points) can be written:
1P̸2p (12 points would be just "1P̸")—traditional style
1p2 (12 points would be just "1p")—format for desktop
14pt (12 points would be "12pt" or "1pc" since it is the same as 1 pica)—format used by Cascading Style Sheets defined by the World Wide Web Consortium
