Keyboard Tilt, Tenting, Orientation

keyboard ergonomics: angles of ergonomic keyboard.

• α is called tilt.
• β is called tenting.
• γ is called orientation.

Tilt

• Positive Tilt (tilt up): traditional keyboard has legs at the “back”, that make them positive tilt, about 10 degrees. This causes your wrists to bend up.
• Negative Tilt (tilt down): some ergonomic keyboards have legs in “front” (near the space bar area), called front riser. These create a “negative tilt”, about 20 degrees.

Tenting

Tenting is raising the middle of the keyboard higher. This is good for preventing hand pronation problem. [see Is Keyboard Tenting Important (Wrist Pronation)]

Split 2-pieces ergo keyboards use legs or stand.

Single-piece ergo keyboards may have tenting builtin.

Orientation

Orientation is about how you have to bent you wrist to the left or right. This is most common in single-piece ergo keyboards, having a inverted V shape. Typically 10 to 20 degrees.
