Which Size is Right for You?
Start with 65% or 75% if you:
- Want a compact board without learning curves
- Use arrow keys daily (spreadsheets, coding)
- Need F-keys occasionally
- Want one keyboard for everything
Consider 60% or smaller if you:
- Want maximum portability
- Have limited desk space
- Are willing to learn Fn layers
- Want the minimalist aesthetic
Pro Tip: Start Slow
Do not jump straight to 40% or smaller. Start with 65% or 75%, get comfortable with layers, then downsize if you want. Most people stick with 65-75% as the sweet spot.
