| Delphi 13 Options: Editor > Display > Font > Line Height |
I recently installed Delphi 13 on my new development machine. And ever since I watch Alister Christie's Code Font video, I've been hooked on using Consolas. I like how it distinguishes between zero and capital "O".
When I brought up the options to change the editor font to Consolas I noticed a new Line Height feature. I played around with some different line heights and for me personally, I settled on 1.2 which fits my eye nicely.

Line Height of 1.2 fits my eye nicely
I don't remember seeing Line Height in Delphi 11. And a quick confirmation of the Delphi 11 IDE options proves it's not there. I installed Delphi 12 but never really used it. I did a quick check and lo and behold the Line Height feature is available in Delphi 12. I must have missed it because I totally skipped using 12 all together.
I also decided to check out if there were any other fonts I might like. Here is the list of alternatives to Consolas that ChatGPT gave me. I tried the ones that were available in Delphi and decided to stick with Consolas.

| Font | What makes it good |
|---|---|
| Fira Code | A modern monospaced font with programming ligatures (so =>, !=, ->, etc. can render as single, clean glyphs). Improves readability of symbol-heavy code. |
| JetBrains Mono | Designed specifically for developers: clean shapes, tall lowercase letters (makes code easier on the eyes), and good clarity even at smaller sizes. |
| Hack | A clean, well spaced monospaced font — good if you like clear distinction between similar characters (0 vs O, l vs 1). Good for plain-text editing or coding without fuss. |
| Cascadia Code | Created by Microsoft for terminals/editors. Has optional ligatures and good support for modern coding environments. Works nicely for both GUI IDEs and terminals. |
| Source Code Pro | A straightforward, clean monospaced font with consistent spacing and good legibility — useful if you prefer simplicity over styling. |
| Iosevka | A very flexible monospaced font (lots of glyph/width/variant options), popular among people who want tight control over how their code appears. |
| DejaVu Sans Mono | A classic, reliable open-source monospace font with wide character coverage and solid legibility — good fallback or default choice on many platforms. |
Here is Alister Christie's video on code fonts I watched many years ago. Wow, this video was released in 2013.

I've tried many times to move away from the Consolas font, but in the end it's always proven to be the best alternative: no annoying ligatures, clear characters, perfect height and width, excellent readability. A must-have. :)
