Keycap Profiles and Materials

Keycap Profiles and Materials

Keycaps are a crucial component of mechanical keyboards, influencing both aesthetics and typing experience. They come in various profiles and materials, each offering unique characteristics. Here,we cover the main keycap profiles and materials, helping you make an informed choice for your keyboard setup.


Keycap Profiles

Keycap profiles refer to the shape and height of the keycaps. Different profiles can affect typing comfort and speed. Here are some of the most common keycap profiles, along with additional ones (estimated height is measured based on the tallest point of the keycaps):


1. SA (16mm)/QXA (14mm)

2. ASA (12mm)

3. DSA (7.6mm)

4. OEM (12mm)

5. Cherry (9.4mm)

6. XDA (9.3mm)

7. MOA(9.8mm)/MOT (9.8mm)/MA(12mm)/MCA (9mm)/MAO (cat ears)

8. MDA (11.7mm)

9. Pudding Keycaps

  • Shape: Typically in OEM profile, but can be found in other profiles as well.
  • Feel: Features translucent sides and bottoms to allow RGB lighting to shine through more vividly.
  • Typing Experience: Same as the base profile (usually OEM), but with enhanced RGB lighting effects for a visually appealing setup.

10. JSA (taller than OEM)

11. CSA (12.5mm)

12. XVX (Cherry + XDA)

Keycap Materials

Keycap materials influence durability, texture, and sound. Here are the most common materials used for keycaps:

1. ABS (Acrylonitrile Butadiene Styrene)

  • Properties: Lightweight, smooth texture, and less expensive.
  • Durability: Prone to shine over time due to finger oils.
  • Sound: Produces a higher-pitched sound.
  • Popular Uses: Common in mass-produced keyboards.

2. PBT (Polybutylene Terephthalate)

  • Properties: Heavier, textured, and more durable.
  • Durability: Resistant to shine and wear, retains texture longer.
  • Sound: Produces a deeper, thocky sound.
  • Popular Uses: Preferred by enthusiasts for custom keyboards.

3. POM (Polyoxymethylene)

  • Properties: Smooth and slightly slippery feel.
  • Durability: Very durable and resistant to wear.
  • Sound: Similar to PBT with a deeper sound.
  • Popular Uses: Used in high-end keycap sets.

4. PVC (Polyvinyl Chloride)

  • Properties: Soft and flexible.
  • Durability: Less durable than ABS or PBT.
  • Sound: Higher-pitched sound.
  • Popular Uses: Less common, used in some budget keyboards.

5. PC (Polycarbonate)

  • Properties: Transparent or translucent, often used for backlit keyboards.
  • Durability: Durable but can yellow over time with UV exposure.
  • Sound: Similar to ABS.
  • Popular Uses: Keycaps designed for RGB lighting.

Choosing the Right Keycap Profile and Material

Choosing the right keycap profile and material depends on your personal preferences and how you use your keyboard.  Here are some considerations:

Typing Comfort

Profiles like Cherry and DSA are great for long typing sessions, while SA and MOA offer a unique aesthetic and feel for those who enjoy retro designs.

Aesthetics

Consider the look you want for your keyboard. SA and MOA profiles provide a vintage feel, while OEM and Cherry are more modern. Pudding keycaps enhance RGB lighting.

Durability

If you want keycaps that last, PBT and POM materials are excellent choices. ABS is more affordable but less durable.

Sound

The material affects the sound of your keystrokes. PBT and POM tend to produce a deeper sound, while ABS is higher-pitched.

By understanding the different keycap profiles and materials, you can enhance your typing experience and customize your keyboard to suit your preferences. Whether you prioritize comfort, aesthetics, or durability, there's a keycap set out there that will meet your needs.
