I hear you: I don't like how skinny the letterforms are. There's an "extended" variant that I find much more pleasing. I put together a customization you can see here: https://codeberg.org/ashton314/iosevka-output (there's a nice screenshot on that page).

You can probably get the proportions you want if you find a way to tweak the line spacing (also possible by adjusting the `leading` option in `private-build-plans.toml` and rebuilding).

From another point of view, the font is just as tall as other fonts, just less wide. So I suspect you are (maybe unconsciously) making an unfair comparison by scaling one font more than the other.

You can see an apples-to-apples comparison here:

(and then put and hold your finger on the last line of text and select another font)
