Factors that Determine Number of Keys on a Keyboard

Different factors that determine the number of keys in a computer keyboard include the keyboard size and the keyboard layout. 

Keyboard Size

The keyboard size refers to the physical dimensions of the keyboard. When it comes to choosing a keyboard, one of the most important factors to consider is the size of the keyboard.

The size of the keyboard will determine the number of available keys, which can be important for both ergonomics and gaming.

There are several keyboard sizes. The full-size keyboard is the largest, and it has 104 keys.

The tenkeyless keyboard is smaller, and it has 87 keys. The 60% keyboard is the smallest, and it has 61 keys.

Full Sized Keyboards

The most common size is the full-sized keyboard. These keyboards have between 104 and 108 keys. Full-sized keyboards are the largest option and they offer the most keys.

This can be beneficial for those who need to have a lot of keys available, such as for gaming or programming.

However, full-sized keyboards can also be more difficult to transport and they can take up more space on a desk.

Tenkeyless (TKL / 80%) Keyboards

Tenkeyless (TKL) keyboards or 80% keyboards are a smaller option that eliminates the numeric keypad.

This can be beneficial for those who want a more compact keyboard that is easier to transport.

TKL keyboards can also be more comfortable to use since they don’t require as much reach for the numeric keypad.

75% Keyboards

75% of keyboards are even smaller than TKL keyboards, and they eliminate the navigation keys (i.e. the arrow keys).

This can be beneficial for those who want an ultra-compact keyboard. However, it can also be more difficult to use, since the navigation keys are moved to a secondary layer.

65% Keyboards

65% of keyboards are even smaller than 75% of keyboards, and they also eliminate the function keys. This can be beneficial for those who want an extremely compact keyboard.

If you would like to choose a 65% keyboard for you, you can look at the guide for the best 65% keyboard written by me.

60% Keyboards

60% of keyboards are the smallest option and they eliminate both the numeric keypad and the navigation keys. This can be beneficial for those who want an ultra-compact keyboard.

However, it can also be more difficult to use, since the numeric keypad and navigation keys are moved to a secondary layer.

You can also check the best 60% keyboards if you would like to choose a 60% keyboard for you.

40% Keyboards

40% of keyboards are even smaller than 60% of keyboards, and they also eliminate the function keys. This can be beneficial for those who want an extremely compact keyboard.

However, it can also be more difficult to use, since the function keys are moved to a secondary layer.

If you have a large desk, you may want to consider a full-sized keyboard. If you have a smaller desk, you may want to consider a tenkeyless or 75% keyboard.

If you have a very small desk, you may want to consider a 60% or 40% keyboard

Keyboard Layout

The three most common layouts are ANSI, ISO, and JIS. ANSI is the standard layout in the United States, while ISO is the standard in Europe. 

JIS is the standard in Japan. Each of these layouts has a different number of keys. ANSI has 104 keys, ISO has 105 keys, and JIS has 106 keys.

ANSI

ANSI is the most common layout in the United States. It has 104 keys and is what most people are used to seeing.

ISO

ISO is common in Europe. It has 105 keys and is very similar to ANSI, but has a different placement for the Enter key.

JIS

The JIS layout is used in Japan. It has a total number of 106 keys in a full-sized keyboard layout.

WKL

The WKL (Winkeyless) layout eliminates the Windows key and application key which reduces the number of keys.
