Detailed Answer
Yes, but less than skill level. Full-size keyboards (104 keys) have standard spacing (19–19.5mm between centers) and a numpad, which helps data entry but moves the mouse further away. Tenkeyless (TKL, 87 keys) removes the numpad – preferred by typists and programmers because the mouse is closer, reducing shoulder strain. 60% keyboards (no arrow keys, function row) can hinder beginners because they rely on layers (Fn key) for punctuation, slowing you down initially. However, pros adapt. Laptop keyboards (compact layout) have smaller keys (17–18mm pitch) – some people type faster on them because finger travel is shorter. Ultimately, comfort and consistency matter most. Choose whatever size lets you keep home row position without stretching uncomfortably.
