Table of regular .ttf fonts

GNU Unifont

• GNU Unifont is a bitmap font with wide Unicode coverage, only good at (nominally) 12px.
• I've added a slashed zero.
• On the original page, Unix Bitmap formats are also available. I haven't modified these yet.
• Probably to extreme range of characters, conversion to "real monospace" with python fonttools ttx has failed so far.
• this is why it has to be selected as a variable pitch font in some terminals, see below for howto.

Trivia

• Personally I have a strong feeling that GNU Unifont closely "inspired" commercial font PragmataPro, although I haven't seen it acknowledged ...
• this would be a real GPL issue anyway, especially as it is one of the most expensive fonts available. and the author even tried to raise money to "make it public domain."
• GNU Unifont's only size fits right into PragmataPro's larger than usual size step between 10 and 11 pixels.
• Liberation Mono by RedHat is a little broader, but has a similar feel to GNU Unifont. It is not fixed to one size.
• PragmataPro has a larger i-dot. smaller line spacing and it seems stretched by one pixel compared with GNU Unifont.
• Luculent also has the large i-dot, is also pixel sharp between 7 and 14px and includes zodiac signs and sparklines.
• By the slight stretching, PragmataPro feels more refined/"designed". Personally, I prefer GNU Unifont most of the time. I like the feel, but surprisingly I like the feel of GNU Unicode better.
• GNU Unifont supports east asian characters, unlike PragmataPro.
• Iosevka is an agreeable Pragmata Pro replacement for antialiased rendering.
• Input Mono has a similar feel to Pragmata Pro, but is available for free in many widths and thicknesses. Input Font Family can also be customized in letterforms, line height, dotted / slashed / unmarked zero etc. http://input.fontbureau.com/preview
• Anka/Coder narrow from 14pt upward with anti-aliasing, I like Anka/Coder Narrow a lot.

Envy Code B 10 ttf

• a bit like the also very useable Dina 9 but with larger line spacing which can be good sometimes.
• now added turkish characters dotless i, capital dotted I and soft g

Generic Mono II

• sans-serif monospace font in the vein of Vera, with a friendly feel
• zero slash has lower angle than most
• now with corrected monospace bit (done with ttx)

Lekton

• has a similar feel to Ubuntu Mono or maybe Share Tech Mono and Klartext Mono
• now with dotted zero in order to distinguish letter oh and number zero
• also done: setting correct monospace flag with ttx

Skyhook Mono Regular

• futurisic monospace font, regular size is free, other styles available as paid offers
• had to correct the monospace bit with ttx from python pip fonttools to be able to use the font w/o workarounds.
• Personally I would prefer it when the author just sets the bit himself, after all it's supposed to be professional.
• I might not actually be allowed to offer it here. Fix it and I take it down.

fn0t

• fancy / futuristic monospace font
• smaller in actual size than point size would suggest
• now with monospace flag in ttx. However, this doesn't seem to be enough for MobaXterm
• zero not yet distinguished from vowel o

fs-regulate

• nice ornamental font
• smaller in actual size than point size would suggest
• I like this one for headers in org-mode, e.g.
• added Euro sign
• now with correct monospace flag in ttx and FontForge

Vintage IBM fonts

• pixel sharp bitmap fonts as .ttf files, only useable at 12pt
• modded: added Euro sign and some turkish characters
• to do for later: "unbreak" the pipe symbol
• IBM now offers IBM Plex Mono, but this is good only from 14pt upwards. Currently I still prefer the old ones.

vintage serif monospace fonts

• pixel sharp bitmap fonts as .ttf files, only useable at 12pt
• from http://int10h.org/oldschool-pc-fonts/

Px437 Compaq 8x16

• good narrow allround mono serif font
• added Euro sign and some turkish characters: dotless i, capital dotted I, soft g

Px437 ToshibaLCD

• slim and very clear

Verily Serif Mono

• derived from Bitstream Vera Serif (proportional).
• best used @ 16pt with antialiasing
• now with corrected underscore, original was miles below visible range
• not unlike the excellent Panama Monospace (which lacks distinguished zero and is proprietary)

HOWTO: Using "variable width fonts" in Putty / MobaXTerm

workaround

due to missing flags, some fonts are not listed as monospace fonts, meaning they are not visible in normal selection

• right-click on an open terminal window
• select "change terminal settings" / "Window/Apperance"
• check the box "allow selection of variable width fonts"
• click the "change" button
• now, all available fonts are listed

correction

• The missing flags could possibly corrected with ttx from python fonttools
• After correction, those fonts are also selectable in Xshell, which doesn't offer the workaround.

font recommendations

beside of what is available here (because I modified it), I'd like to make you aware of the following fonts

other sans-serif monospace pixel suggestions

• Tamsyn
  • Tamsyn 10x20 has that futuristic "square" feel of quadra-style fonts like White Rabbit, Earth 2073 or Otonokizaka Mono II or maybe Lekton - but it is pixel sharp. The jagged "s" might feel nervous or energetic. Try it in pure green on black...
  • Tamsyn 7x13 is a quite small font that still feels relaxed.
• Raize.
  • 12px is a good standard font that can be replaced with IBM ISO 9 for less edge.
  • 11px is small, broad and edgy, just like Triskeline is small, broad and round.
• Dina
  • Dina 9 is nearly equivalent to Envy Code B 10 TTF modified above, has less line spacing and maybe feels a little more joyful.
  • Dina 8 feels more relaxed than Tamsyn 7x14.
  • Dina 6 is broader than Luculent 7. Size comparable to Sheldon / Sheldon Narrow.
• Triskweline quite small, calm and broad.
• Luculent is quite narrow, has a large dotted i and a wide range of characters. There are individual fonts for each pixel size. The zero is "backslashed" ...
  • Luculent 14 has single pixel width stems, which is unusual for that size and reminds me of plotter and DIN stencil fonts.
  • Luculent 12 is fancy but readable, not unlike Ubuntu Mono 13
  • Luculent 11 is a size that I always come back to.
  • Luculent 9/10 is in same territory as Envy Code B 10px and Dina 9, but more rounded and with large i-dot
  • Luculent 7 is surprisingly readable for the size (smaller than Dina 6) though feeling a little strained.
• Sheldon Narrow (a ProFont replacement by Sheldon Simms) and especially the more widely spaced Sheldon are very small but quite readable and good for side-by-side comparison of code.
• zevv-peep: both beautiful and good to read though sadly lacking character range. Somewhere between Luculent and Ubuntu Mono / Lekton. Listed as "peep" in font list.
• Minglan Code has great pixel sharp sizes together with extreme Unicode ranges. https://en.m.fontke.com/font/10245073/download/?fromlang=en

other serif monospace suggestions

pixel sharp fonts

• PT Mono by Paratype: Medium width serif font that has wide range of pixel sharp small sizes and includes cyrillic and greek
• Px437 IBM Thin1 (relaxed feel, not yet modified)
• Nimbus Mono somehow, this one calms me down. Broad and thin. pixel sharp in 14px
• Rursus compact mono robust medium-with typewriter that feels "handmade". needs anti-aliasing (not cleartype) and preferably larger sizes from 15pt upward, but has nice range and feel
• Libertinus Mono more typewriter-like than PT Mono. Pixel sharp in 11pt

needing anti-aliasing

• Go Mono: quite narrow, needs anti-aliasing
• Luxi Mono: not bad but lacks zero-oh distinction. maybe use my corrected version of Verily Serif Mono instead.
• Selectric by Paradox: Very good Courier replacement. Has nonslashed but distinguishable zero.
• Courier Prime Code. West coast calm but needs anti-aliasing.
• Panama Monospace slim, elegant proprietary font, yet without distinguished zero
• Damien Typewriter by DamienG: the Comic Sans of terminal fonts... could use some additional characters. - various vintage typewriter fonts by Lukas Krakora and Peter Wiegel e.g. Erica Type and Oceanside Typewriter
