Selecting a mechanical keyboard with the proper size and layout is essential. The size layout largely determines the uniqueness of a mechanical keyboard, and likewise, the layout also determines its limitations. With choices like 60%, 75%, 80%, 100%, and more, it makes sense to ask which is ideal for work or gaming. This post explains each size so you can make an informed choice.

Keyboard Key Composition

The number of keys on each keyboard size varies. Do you know the key composition for a keyboard? Which keys are missing from 60% of keyboards? We need to know the key composition to understand better the difference in the number of keys on each keyboard size.

  • Typing & control keys: Which include letters, numbers (row), punctuation, and modifiers (Shift, Ctrl, Alt), are the main area for text operations.
  • Function Keys: The twelve function keys F1–F12.
  • Number keys (row): Number keys in a row.
  • Arrow Keys: The four directional keys (up, down, left, and right).
  • Editing keys: Keys such as Insert, Delete, Home, End, Page Up, and Page Down.
  • Number pad: A separate section of keys for number entry and calculations, typically found on the right side of the keyboard on full-size keyboards.

Now that the most common keyboard sizes are full-size (100%), TKL (80%), 75% and 60%, besides these sizes, there are some other sizes, including 1800 compact, 65%, and 40%. Let's take a look at the differences in the specific key combinations of keyboards of these sizes.

The Comparison of Keyboard Sizes

The percentage of the layout represents the approximate area of the standard keyboard occupied by the layout. The lower the percentage of the layout, the smaller the keyboard size, the more portable it is, and the more dependent on the use of key combinations. Conversely, keyboards with larger percentages require fewer key combinations to remember and also take up more desktop space. 

Let’s check the details for each size, understanding these details will help you better choose the right keyboard for your needs.

Full-size / 100%

A full-size keyboard includes all of the keys present in the standard keyboard layout. The most common configuration is the traditional 104-key keyboard. 104 keys are now one of the most popular keyboard layouts.

Even when using a 100% full-size keyboard, the most comfortable range for our hands is the 60% main key area. You can easily reach the number keys with a stretch of your fingers and type symbols with both hands.
For typing tasks, this 60% area is the optimal sweet spot. Your wrists can stay in place without moving your arms to reach distant arrows or editing keys, allowing you to type without extensive hand movements. This is the charm of a 60% keyboard.

Other Size or Layout Keyboards (Non-Standard Layouts)

Ortholinear keyboards have a grid layout, with each column of keys aligned vertically. Unlike standard staggered keyboards, which have keys offset in each row to permit natural finger angling, ortholinear keyboards contain keys that are lined horizontally and vertically, similar to a grid or matrix.

The existence of a numeric keypad is generally to facilitate data entry in the banking or accounting industries, or as an external option for users who lack a numeric keypad, but this is relatively rare.

Split / Ergonomic Layout
A split or ergonomic layout keyboard is designed to reduce strain and improve comfort for the user by promoting a more natural typing position.The keyboard is divided into two separate halves that can be positioned independently. This allows users to position each half to align with their natural hand, wrist, and arm position.

Why Does Size Matter?

As I previously stated, the size of a keyboard dictates its distinctiveness while also limiting its functionality. Because we all have different locations, scenarios, and tastes when it comes to keyboards, different sizes provide us with possibilities to fulfill a variety of demands.

Desk Space: Larger keyboards, such as full-size keyboards (100%), require more space, which may be an issue if you have a tiny desk or desire more room for other devices, such as mice.

Portability: Smaller keyboards, such as TKL (Tenkeyless), 75%, 65%, and 60%, are more portable and easy to transport, making them ideal for travel or LAN parties.

Usage Preference: Different keyboard sizes allow different usage styles. Gamers usually favor compact layouts (e.g., 60%) for more mouse movement area, whereas office workers may prefer full-size keyboards with extensive key sets, including a numeric keypad.

How to Choose the Right Keyboard Size?

In general, you should examine your usage needs as well as your typing and gaming preferences.

  • For those who regularly enter numbers, the full-size keyboard layout with its dedicated numeric keypad is the most practical option.
  • If compactness is not a priority, but you still want to conserve desk space, the TKL (Tenkeyless) layout is a great option. It keeps recognizable key locations while drastically shortening the keyboard, making it popular among gamers who benefit from more mouse movement space.
  • For those who rarely use function keys or have limited desk space, as well as those who want portability, the 60% and 65% layouts are recommended. Also, 60% and 65% are suitable for game players because of their ergonomic features and extra mouse space. These small keyboards provide vital keys while saving up desk space or allowing for convenient transportation.

By considering these aspects depending on your personal needs and tastes, you can select a keyboard size that improves your productivity, comfort, and enjoyment of using your computer.


Selecting the appropriate mechanical keyboard size is critical for both functionality and comfort. Each keyboard size, from 40% to full-size (100%), offers distinct traits and limits that cater to various preferences and needs.

Understanding the exact key components and the distinctions between sizes enables you to make an informed choice. Consider your usage circumstances, desk space, and personal preferences when choosing a keyboard size for work, gaming, or travel.
