In ExtraLight and ExtraLight Italic variants, each character is wider than their counterparts in other variants.

Tested on Intellij IDEA and Notepad++.

I was curious about this, so I did some investigation:

Focusing on this part of the bug report, I can see what you mean:

The last t in Document seems to end up just slightly further to the right than in the screenshot above (compare with the 🔎).

However, I can also see that there’s some contrast applied to the letters, see for example the e and s – that’s not how those letters look like in Source Code ExtraLight:

In your screenshot, you’ll see quite a bit of contrast in the e, while the design has virtually none.

The letters are all the same width across all the weights of course:

So what I think is going on here is Notpad++ compensating for a font it deems “too thin” to display. This is something that’s called “smear bolding”, and is known from decades-old versions of MS Word.

FWIW, I don’t observe the issue as claimed in my SublimeText setup:

The conclusion is – this can only be fixed by Notepad++ – either via a bug report, or user settings.

@SubhamSatyajeet There is a work-around. The old "smear-bold" only affects fonts with a usWeightClass of under 250. For example it would affect ExtraLight (200) and Thin (100). (the correct weights) So as a work-around some fonts have ExtraLight set to 275, and Thin set to 250 - to prevent the stupid text engine from distorting the characters. Here is the two ExtraLight fonts with the weight set to 275. Try these: SourceCodePro-ExtraLight-275.zip

@frankrolf I made a mistake in my first comment - The two editors where this was reproducible were IntelliJ IDEA and Notepad++. Sublime Text works as expected. I'll close this issue since it is not related to the fonts themselves.

@kenmcd Thanks for the 275 width fonts, this did work for IntelliJ IDEA! (not for Notepad++)
