Why don't Google sites support 14pt font size?

I suppose you might as well ask why other point sizes are skipped as well. It would be impractical to list them all. Having said that, I think it's a good question why 14pt is skipped.Standardized sizes The first thing to state is that the point sizes have been standardized. Among others there's Brevier (8pt), Bourgeois (9pt), Long Primer (10pt), Small Pica (11pt), Pica (12pt), English (14pt), Colombian (16pt) and Great Primer (18pt). Note how the standardized sizes come in incremental steps in the larger range—increasing as the sizes become larger. Since body text is usually in the 8–12pt range, there will be more sizes defined here. For example, there's also a 10½pt size, though it doesn't have a specific name. For sizes below 8pt you will find more ½pt incremental sizes.Web standard Standardized sizes aside, it's strange to me indeed that the 14pt size is skipped. This is conjecture from my part, but one explanation could be that the point sizes are actually pixel sizes and since 16px has been standardized for the web (though most websites tend to use 14–15px), 14px is depreciated and thus it's left out to urge you to use 16px instead. It seems bad practice however to use pt as a unit when they're actually sizes in px, though I can imagine if the sizes were expressed in px, people may get confused by the big sizes. For example, 12pt equals 16px, whereas 16pt is 22px.Optical standard One other explanation I can think of is that the 10pt for body is supposed to go with 16pt for headings while the 12pt for body is supposed to go with 18pt for headings, thus there would be no need for 14pt. 8pt would be for captions and 24pt for display use. Thus you would have some extent of correspondence with the system of optical sizes.
