Mechanical Keyboard Sizes and Layouts

 

 

Here follows a visual introduction to keyboard sizes, profiles, and layouts, along with some key generalizations.

 

Sizes

Keyboard size is based on the length of the keyboard compared to a full-sized one. The most common sizes are full-sized (100%), tenkeyless/TKL (80%), and compact (60%). The number and types of keys available for each size varies between keyboards, with generalizations being less applicable once you dip into the compact zone.

Profiles

Keyboard profile is the vertical shape of the keyboard, as in, the heights of each row of keys relative to one another. Note the angle of the backplane, as well as the heights and shape (sculpted/angular or uniform/flat) of each key row.

  • Curved: Backplane is curved, keycaps are sculpted and at the same height.
  • Contoured/Sculpted: Backplane is angled, keycaps are sculpted and at different heights.
  • Staircase: Backplane is angled, keycaps are slightly sculpted and at the same height.
  • Flat: Backplane is level, keycaps are level and at the same height.

 

Mechanical/Physical Layouts

Mechanical layout is the physical arrangement of keys on the keyboard, and is different from functional layout (Section [2.3]). The most common layouts are ANSI, ISO, and JIS (JIS won’t be covered here). Variants and other layouts do exist besides the ones listed below.
 
Note: U refers to an arbitrary unit of measurement. For instance, if 1U is the length of a standard key, 2U will be roughly double that length.

 

ANSI (American National Standards Institute)

  • 2U Backspace Key
  • 1.5U Tab Key
  • 1.75U Caps Lock Key
  • 2.25U Enter/Return Key
  • 2.25U Left Shift Key, 2.75U Right Shift Key
  • 1.25U Alt Keys
  • Backtick/Tilde Key: Below Esc Key, Beside 1 Key
  • Hashtag Key: Between 2 and 4 Key
  • At Symbol Key: Between 1 and 3 Keys
  • Backslash/Pipe Key: Above Enter/Return Key

 

ISO (International Organization for Standardization)

Functional Layouts

Functional layout is the firmware-mapped arrangement of keys on the keyboard, and is different from mechanical/physical layout (Section 2.3). The most widely used layout is QWERTY, but other layouts and variants of these layouts also exist and may be more popular in certain countries.
