I see the following problems with font size: All these fonts have the identical size of 22В pt: For example, if I align em squares (= set same font size) from two different fonts, I get very different вЂњmвЂќ height:ДЄnother example. That means that different fonts set at the same size might have drastically different perceived size. When I say em size is absolutely arbitrary and is not related to anything in the font at all, itвЂ™s not an exaggeration. Too bad itвЂ™s invisible and no element in font matches it. This square will be 32/43В px tall/wide if you set the font size to 32В pt. Long story short, this square is what you actually control when setting font size.

Meaning, if I open Fira Code and draw em square, it will not align with anything at all: In a digital type, though, an вЂњem squareвЂќ is (and IвЂ™m quoting Wikipedia):ДЄ grid of arbitrary resolution that is used as the design space of a digital font. Why was the height called вЂњem sizeвЂќ? Because letter вЂњmвЂќ was coincidentally a square, and вЂњmвЂќ width = character piece height = em size. In traditional metal type, em size is the height of the character piece. This is because font-size sets the so-called вЂњemвЂќ size. But these numbers are still nowhere to be seen. So user requesting 32В pt font is actually requesting 32В px on macOS and 43В px on Windows. VS Code seems to take editor.fontSize value directly in pixels. Same font, same pt size, no relative scaling This holds to this day: 16В pt text on Windows is в…“ larger than 16В pt text on macOS. So they figured, why not make everything в…“ larger?ДЄnd they did, indeed. Why not 72? Not because they had better displays (they didnвЂ™t), but because 72 gave you too few pixels to render a legible text. In the spirit of true cooperation, Windows uses 96В PPI instead of 72.

Nice! Of course, Mac displays have improved their PPI since, but the convention stays. If you view text there, its physical size on the screen will match its physical size when printed. Why the number 72? Turns out, original Macs used to have displays with exactly 72 PPI.

If you put macOS on a 32вЂќ monitor and a 24вЂќ monitor, both set to 1080p resolution, youвЂ™ll get identical pixel size, but not physical size, undermining the original idea.

Instead, macOS always uses 72В PPI to convert points to pixels. If I want to see my letters 2 inches tall, I can do that by setting the font size to 144В pt. The idea here was that you set font size directly in physical units, ignoring minute details like screen resolution. Point is a physical unit of measure, equal to 1вЃ„72 of an inch (0.353В mm), originating from typography. What is going on? PointsДЇirst, that size is not in pixels, itвЂ™s in points. If we measure letters themselves, number 32 is nowhere to be seen:ДЈ2 is not the width or height of a letter, neither is it a capital letter height, an x-letter height, an ascender height, a descender height. What happens when you set 'font_size': 32 in your favorite editor? I wouldвЂ™ve told you anyway, but IвЂ™m glad that you asked.
