Font Selection Decision Tree¶

Do you want ligatures?
├─ Yes
│  ├─ Extensive ligatures → FiraCode
│  └─ Moderate ligatures → JetBrains Mono
└─ No
   ├─ Want personality → SeriousShanns (you have this!)
   ├─ Want density → Iosevka
   ├─ Want classic → Source Code Pro or Meslo
   └─ Want retro → Terminess

Ligature Comparison¶

Extensive Ligatures (FiraCode)¶

->  →    =>  ⇒    !=  ≠    ==  ═    ===  ≡
>=  ≥    <=  ≤    ||  ‖    &&  ＆   ::  ∷

Moderate Ligatures (JetBrains Mono)¶

->  →    =>  ⇒    !=  ≠    ==  ═
>=  ≥    <=  ≤    ::  ∷

No Ligatures (Source Code Pro, Meslo, SeriousShanns)¶

-> -> => => != != == == === ===
(Characters stay separate)

Width Comparison¶

At same font size (14pt):

Narrow (Iosevka):

const myFunction = () => { return value; }  // 80 chars

Standard (FiraCode, JetBrains, Source):

const myFunction = () => { return value; }  // 80 chars (wider)

Impact: Narrow fonts fit ~10-15% more code horizontally.

Character Differentiation Test¶

Critical characters that must be distinguishable:

0O  (zero vs capital O)
1lI (one vs lowercase L vs capital i)
`'  (backtick vs quote)
-–— (hyphen vs en dash vs em dash)
,;  (comma vs semicolon)

All fonts in your collection handle this well. Specifically optimized for code.

Recommended Testing Order¶

Based on popularity, features, and your preferences:

Week 1-5: The Essential Five¶

JetBrains Mono - Modern, ergonomic, ligatures
FiraCode - If Week 1 feels good but want more ligatures
Source Code Pro - If you want no-nonsense, professional
Iosevka - If you want maximum density
Meslo - macOS familiarity

Week 6-8: The Alternatives¶

SeriousShanns (re-test your current favorite)
Any wildcard that caught your eye

Skip Unless Curious¶

ComicMono (you have SeriousShanns)
Terminess (niche retro use)
DroidSans (better options exist)
IosevkaAile/Etoile (not for terminal)

Font Pairing Recommendations¶

If you end up keeping 3-5 fonts, good combinations:

Balanced Trio:

Daily: SeriousShanns (fun, your favorite)
Professional: Source Code Pro (screen sharing, work)
Dense: Iosevka (small screen, lots of code)

Ligature Lover Trio:

Main: FiraCode (extensive ligatures)
Alternative: JetBrains Mono (when FiraCode feels busy)
Fun: SeriousShanns (personal projects)

Minimalist Duo:

Main: JetBrains Mono (all-around excellent)
Backup: Source Code Pro (alternative feel)

Maximum Variety:

Modern ligatures: FiraCode
Clean professional: JetBrains Mono
Classic: Source Code Pro
Personality: SeriousShanns
Density: Iosevka

(Five fonts max - don't exceed this!)

Font Sizes by Screen¶

13" Laptop (1440p)¶

12-13pt: Iosevka (narrow, fits more)
13-14pt: FiraCode, JetBrains, Source
14-15pt: SeriousShanns, Meslo

15" Laptop (1080p)¶

13-14pt: Most fonts
14-15pt: Comfortable for long sessions

27" 4K Monitor¶

14-16pt: Standard
16-18pt: If far from screen

General Rule¶

Start at 14pt
Adjust ±1-2pt based on comfort
Bigger = less eye strain, less code visible
Smaller = more code, more eye strain

Common Questions¶

Which font is "best"?¶

There isn't one. Depends on:

Your vision
Screen size and resolution
Language you code in
Personal aesthetic preference
Ligature preference

Best approach: Test 5-10, pick favorite.

How long to test each?¶

Minimum: 3 days of real work Recommended: 1 week Ideal: 2 weeks

What if I like multiple fonts?¶

Keep 3-5 max:

Main daily driver (80% of time)
Professional alternative (for work/screen sharing)
Fun option (personal projects)
Optional: specialty (dense code, specific use)

Do I need all font weights?¶

No. For each font family:

Keep: Regular, Bold, Italic, Bold Italic
Skip: Light, Medium, SemiBold, ExtraBold, Black

See Font Weights Guide for details.

What about Iosevka variants?¶

For terminal/coding:

Use: Iosevka Nerd Font or Iosevka Nerd Font Mono
Skip: IosevkaAile (sans-serif, not monospace)
Skip: IosevkaEtoile (serif, not monospace)
Maybe: SGr variants (stylistic alternatives)

After Testing: Cleanup¶

Once you've found your favorites (3-5 fonts):

Keep¶

~/Documents/code_fonts/
├── FiraCode*.otf (if you liked it)
├── JetBrains*.ttf (if you liked it)
├── SeriousShanns*.otf (you like this!)
└── (2-3 more you actually use)

Delete¶

Everything marked "dislike" in your font-sync log.

Archive¶

Fonts you're unsure about, save for 6 months then delete.
