Ergonomics and Angles
Typing angle, front height, and Alice layouts.
Core Analysis
Why is front height critical?
A front height above 19mm forces excessive wrist extension, leading to RSI over long sessions. High-profile boards require palm rests to correct the geometry.
Data Overview
| Metric | Target | Implication |
|---|---|---|
| Front Height | 17-18.5mm | Comfortable without wrist rest |
| Typing Angle | 6-7 degrees | Optimal row visibility |
Source citation: Ergonomic standards (OSHA guidelines) suggest maintaining a neutral wrist angle (0-15 degrees extension).

Common Mistakes
- Buying an Alice board and still touch typing incorrectly (crossing hands over the split).
- Setting feet to extreme 10+ degree angles.
FAQ
- Does Alice actually help RSI?
- It reduces ulnar deviation by angling the clusters, but does not solve wrist extension. Only tented splits solve both.
