Keyboard stabilizers are components used in mechanical keyboards to ensure that larger keys, such as the spacebar, enter, and shift keys, operate smoothly and consistently. They prevent these keys from wobbling, shaking, or tilting when pressed, providing a stable typing and gaming experience.

Stabilizers are typically placed under these larger keys and are connected to them via a bar mechanism that balances the keypresses. Stabilizers consist of a stabilizer wirestabilizer inserts, and stabilizer housings. They work by reducing the indirect movement of these larger keys, ensuring a more consistent and stable typing experience.

Understanding the Role of Stabilizers

Mechanical Keyboard stabilizers, often referred to as ‘stabs‘, are integral components designed to enhance the stability and consistency of keystrokes, particularly for larger keys. Understanding the anatomy and types of stabilizers is essential for selecting the right ones for your keyboard.

1. Anatomy of Stabilizers:

  • Components: Consist of the slider, the housing, and the wire, which work together to prevent side-to-side movement and ensure smooth up-and-down motion of the keycap.
  • Screw-in Stabilizers: Include housings, stems, a wire, screws, and washers, offering a more secure attachment to the PCB.
  • GMK Screw-In Stabilizers: Come pre-assembled, simplifying the installation process.

2. Size Measurement: Stabilizer sizes are measured in units (U), just like keycaps. One unit (1U) equals the width of a standard key.

  • Common Sizes: There are three main stabilizer sizes:
    • 2U: This is the most common size, used for keys like Shift, Enter, Backspace, and Ctrl.
    • 6.25U: This size is specifically for the standard spacebar on most keyboards.
    • 7U: This is a less common size used for some non-standard, wider spacebars. You’ll likely only need this if your keyboard has a unique layout.

3. Mounting Styles: Cherry MX stabilizers are available in Plate-mounted, Screw-in, and Snap-in styles, with each providing different levels of security and ease of installation.

For a standard full-sized keyboard, you’ll typically need:

  • 1x 6.25U stabilizer for the spacebar
  • 7x 2U stabilizers for the Shift, Enter, Backspace, and Ctrl keys (one for each)

If you have a different keyboard layout (TKL, 60%, etc.), you might need fewer 2U stabilizers. 

How many stabilizers do I need for my keyboard?

Knowing exactly how many stabilizers you need can be tricky, especially with all the different keyboard size out there. 

We’ve got the ultimate sheet for popular keyboard layouts, including some unique ones you might not find elsewhere:

You can also try searching online forums or communities for people who use the same keyboard as you. They might have already made a guide on how many stabilizers you need.

The Different Types of Keyboard Stabilizers

In this section, we will discuss the two main types of stabilizer keyboards: plate-mounted stabilizers and PCB-mounted stabilizers. We will cover the advantages and disadvantages of each type, as well as some famous brands and models.

1. Plate-mounted Stabilizers

Plate-mounted stabilizers are the most common type of keyboard stabilizer. They are attached to the keyboard plate, the metal sheet supporting the keycaps. Plate-mounted stabilizers are generally easier to install than PCB-mounted stabilizers but can be noisier.

Plate-mounted stabilizers are typically made of plastic or metal and come in various colors to match keyboard builds. Some popular plate-mounted stabilizers include Durock, Cherry, and Costar stabilizers.

2. Screw-in Stabilizers

Screw in stabilizers are a type of mechanical keyboard stabilizer that is considered to be superior to the more common clip-in stabilizers. They are mounted onto the PCB (printed circuit board) of the keyboard using screws, which provides a more secure and stable connection. This can help to reduce key rattle and wobble, especially on larger keys such as the spacebar, Enter, Shift, and Backspace keys.

This guide will focus on installing plate-mounted stabilizers – a common choice among keyboard users.
