The Ergonomic Keyboard Index (EKI) is my 0–20 scoring system for comparing ergonomic keyboards on comfort, practicality, and buildability.
If you want the full explanation of every category and how the scoring works, read the dedicated article:
Ergonomic Keyboard Index (EKI) – Measuring Keyboard Ergonomics at a Glance.
Below you’ll find a concise table with all keyboards I’ve reviewed using EKI. This page will grow over time as I add more boards.
Keyboard EKI Scores
| Keyboard | Core Ergonomics (max 12) | Practicality & Portability (max 5) | Buildability (max 3) | Final EKI Score (0–20) |
|---|---|---|---|---|
| Ferris Sweep (34-key) | 9/12 | 4/5 | 3/3 | 16/20 |
More keyboards coming soon – each new review that uses EKI will be added here so you can compare them at a glance.
Thanks for reading!
