What Are CYL Keycaps? Complete Guide To Cylindrical Keycap Profiles
Have you ever wondered why typing on some mechanical keyboards feels so satisfying and surprisingly precise? The secret might lie in a small but crucial detail: the keycap profile. In that diverse world, CYL keycaps emerge as a perfectly balanced choice between comfort and performance. So, what are CYL keycaps? This article will be your comprehensive guide, explaining everything you need to know about this cylindrical keycap profile, from its structure and typing feel to how to choose the perfect set, whether you’re a beginner or a seasoned mechanical keyboard enthusiast.
The Distinctive Shape & Structure of CYL Keycaps
To fully understand CYL, we need to dissect the unique structure that made its name. This isn’t just about aesthetics, but the science of the typing experience.
“Cylindrical” – A Concave Surface that Cradles Your Fingertips
The core identifying feature of CYL keycaps is the key’s top surface.
“CYL” is short for Cylindrical. Instead of being flat or spherically dished, the surface of a CYL keycap has a slight concave curve across its width, like the inner surface of a cylinder. This design is intentional:
- Cradles your fingertips: Helping your fingers naturally find the center of the key.
- Increases contact area: Providing a more secure and stable feeling when typing.
- Reduces slippage: Minimizing the chance of your fingers slipping to adjacent keys, especially during fast typing.
This is a major difference compared to spherical keycaps (like SA) or uniform flat keycaps (like DSA).
“Sculpted” Profile & Ergonomics
Most CYL keycap sets feature a sculpted profile. This means the rows of keys have different heights and angles, forming a gentle curve when viewed from the side.
This ergonomic design (ergonomics keycap) offers direct benefits:
- Natural hand posture: It helps keep your wrists and fingers in a more comfortable position, reducing fatigue during long sessions.
- Optimized typing travel: Your fingers don’t have to reach as far to hit keys in the top rows.
- Improved speed and accuracy: The optimized typing angle for each row helps you type faster and more precisely.
Typing Feel & Sound of CYL Keycaps
Shape is only half the story. The actual typing experience and the sound produced are what make users love or hate a keycap set.
The “Finger Fit” Feel – Smooth and Precise
The cylindrical concave surface creates a distinctive “snug” feeling, which enthusiasts often call finger fit. When typing, you can clearly feel your finger “sinking” slightly into the key, which helps with subconscious positioning.
This experience is particularly useful for:
- Programmers & Writers: Minimizing typos during long work sessions.
- Gamers: Helping to control movement and ability keys with confidence, without needing to look down at the keyboard.
Overall, CYL provides a smooth typing experience that is stable and less wobbly than taller profiles like SA.
Typing Sound (Noise Level) – “Thock” or “Clack”?
Sound is an integral part of the mechanical keyboard experience, and CYL keycaps can produce a very diverse sound spectrum, largely dependent on the material.
- PBT CYL keycaps: Tend to produce a deeper, cleaner, and more solid sound (often described as “thocky” or “creamy”). This sound is highly sought after in high-end custom builds.
- ABS CYL keycaps: Tend to create a slightly higher-pitched and clearer sound (closer to “clacky”). GMK CYL sets (which use doubleshot ABS plastic) are famous for this signature sound.
Common CYL Keycap Materials and Brands
The material not only affects the sound but also determines the durability and appearance of the keycap set. The two “giants” in the industry are ABS and PBT.
Comparing ABS and PBT for CYL Keycaps
| Criteria | ABS Keycaps | PBT Keycaps |
|---|---|---|
| Surface Feel | Smooth, slick | Slightly textured, grainy |
| Durability | Prone to wear and developing a shine over time | Very durable, resistant to wear and chemicals |
| Sound | Higher-pitched, clearer (“clacky”) | Deeper, fuller, and cleaner (“thocky”) |
| Colors | Brighter, more vibrant colors | Slightly more muted colors |
| Price | Generally cheaper (except for premium brands like GMK) | Generally more expensive due to higher production costs |
Expert’s advice: If you prioritize durability, a textured feel, and a deep sound, choose PBT. If you love vibrant colors and the signature sound of major brands like GMK, ABS is an excellent choice.
Prominent Brands You Should Know
- GMK (Germany): Considered the gold standard for ABS keycaps. GMK CYL sets (they call it Cherry profile, but it is fundamentally very similar) use thick ABS plastic and doubleshot keycap technology for permanent legend durability.
- ePBT (EnjoyPBT): Famous for high-quality, thick PBT keycap sets at a reasonable price. An ePBT keycap set is a great choice for those who want a premium PBT experience without breaking the bank.
- Domikey: A good alternative to GMK in the doubleshot ABS segment, with a more accessible price point but still respectable quality.
Comparing CYL with Other Keycap Profiles
| Profile | CYL (Cherry/OEM-like) | SA Profile | DSA Profile | OEM/Cherry Profile |
|---|---|---|---|---|
| Height | Medium – Low | Very High | Low, Uniform | Medium – Low |
| Surface | Cylindrical | Spherical | Spherical, Shallow | Cylindrical |
| Design | Sculpted | Sculpted | Uniform | Sculpted |
| Typing Feel | Balanced, comfortable, precise | “Retro,” deep travel, resonant sound | Minimalist, easy to rearrange keys | Fast, familiar, standard |
| Best For | All-purpose: typing, coding, gaming | Fans of vintage style | Minimalists, ortholinear keyboard users | Most mainstream users |
To truly understand the value of CYL, let’s put it head-to-head with other major contenders.
- CYL vs. SA Profile: SA is significantly taller, giving a more “lofty” or “towering” typing feel and a very resonant sound. CYL is lower, easier to get used to, and provides a more stable typing feel.
- CYL vs. DSA Profile: DSA has a uniform height across all rows, making it suitable for those who like to rearrange their key layout. However, CYL’s sculpted design and finger-cradling surface offer much better key homing.
- CYL vs. OEM & Cherry Profile: This is the group with the most similarities. CYL is essentially a general term for cylindrical profiles like OEM and Cherry. Cherry profile is typically a bit shorter than OEM, favored by gamers for its slightly shorter key travel.
How to Choose the Right CYL Keycap Set for You

FAQ – Frequently Asked Questions About CYL Keycaps
Are CYL keycaps good for gaming?
Very good. The sculpted design and finger-cradling surface help you locate skill keys (QWER) and movement keys (WASD) accurately without looking. Cherry profile (a type of CYL) is especially popular among professional gamers.
Are CYL keycaps compatible with all types of switches?
Most CYL keycap sets on the market today use the Cherry MX stem mount (a cross shape), which is compatible with the vast majority of popular mechanical switches like Cherry, Gateron, Kailh, Akko, etc. However, always check the product specifications before buying.
How do I clean CYL keycaps?
You can remove the keycaps and soak them in warm water with a mild soap (like dish soap), then use a soft brush to scrub them. With PBT keycaps, you can be more confident as they are resistant to chemicals. Avoid using alcohol or harsh detergents on ABS keycaps.
CYL Keycaps isn’t an overly complex term. It’s simply a general name for keycap profiles that have a cylindrical concave surface and an ergonomic, sculpted design, with Cherry and OEM being the two most typical representatives. They offer a perfect balance of comfortable typing feel, high precision, and aesthetics, making them suitable for almost every type of user. Hopefully, this article has fully answered the question “what are CYL keycaps” and given you more confidence in choosing the next keycap set for your mechanical keyboard.
