The short answer is no, keycaps are not one-size-fits-all switches. Keycap compatibility depends on factors such as the switch type, keycap profile, and keyboard layout. While Cherry MX-style switches are common, all keycaps may not fit on all keyboards or switch types. Our article will explore the factors that affect keycap compatibility and help you find the best keycaps for your keyboard.
No, keycaps are not universal. The fit of keycaps varies based on several factors such as switch type, keyboard layout, and the keycap profile. While Cherry MX-style switches are the most common and compatible with a wide range of keycaps, other switches like Topre, low Choc, or Alps may require specific keycap designs, limiting compatibility options.
The variability in keycap size, shape, and design means that not all keycaps will fit every keyboard. Different keyboards have unique layouts and key sizes, particularly for larger keys like the spacebar and enter key. Therefore, when purchasing keycaps, you need to make sure they are designed to fit your keyboard’s specific switch and layout.
Keycaps are not the same size. Different keyboard layouts come with a variety of keycap sizes, especially for larger keys like the shift, enter keys, or standard spacebar size. For example, the right shift key can be 1.75u on some keyboards and 2.75u on others. Other keys, such as the spacebar, may vary between 6.25u and 7u depending on the layout. So, how to know if keycaps will fit? Always verify keycap sizes and consult a dimensions guide to make sure the keycaps will fit your keyboard.
If you're unsure about the sizes of your keyboard, checking a keycap dimensions guide is essential. Some popular layouts, such as full-sized, TKL, or 60% keyboards, all have distinct keycap size variations. To dive deeper into understanding keycap dimensions, you can explore this keycap dimensions guide for beginners to help identify the right fit for your keyboard.
Keycap Height
Most keyboards on the market share the same height ("OEM" profile). This is the standard keycap profile for keyboards. Also, the OEM profile is known for its iconic flat top, a slant to support the user's fingertips, and a slight cylindrical bow.
Spacebar Compatibility
The most popular spacebar length of all is around 6.25 units, which is roughly 158mm long measured from the bottom of the spacebar.
Modifier Compatibility
Here are some of the most common modifier layouts for keyboards:
Caps Lock Compatibility
A caps lock is the lock key found on most keyboards. It is located in R3 and usually around 1.75u.
Enter Key Compatibility
Enter Key or the keyboard's Return key can come in all shapes and sizes, from the backwards-L shape, J-Shaped Enter key to a simple rectangular.
Right Shift Compatibility
Keyboards that have a compact design usually come with a smaller right shift. This makes the right shift keycap sizes differ on each layout. Additionally, some can also be on different rows too. The right shift is available from 1.75u to a full 2.75u.
Key Stem
Well, this is basically the plastic part that connects your switch to the keycap. And, the type of stem defines what keycaps you can use on your keyboard. The most common one is the Cherry MX which has a cross-shaped stem.
Keycap profiles refer to the shape and height of the keycaps, which influence typing comfort, feel, and performance. Here is a table that highlights popular keycap profiles and their unique features:
| Keycap Profile | Features |
| Cherry Profile | Sculpted rows with angled tops, low profile (9.4mm), popular for speed and comfort |
| OEM | Medium height (11.9mm), commonly found on pre-built keyboards, suitable for general use |
| SA | Tall (16.5mm), spherical tops, ideal for those who prefer a vintage feel |
| DSA | Low profile (7.6mm), flat and uniform, preferred for fast typing |
| XDA | Flat tops, uniform across all rows, medium height (9.1mm), great for smooth typing |
Each profile offers a unique typing experience. Read this Guide to Different Keycap Profiles for a more in-depth understanding of keycap profiles.
Not all keycaps fit all switches, and not all switches are compatible with every keycap set. Cherry MX switches are the most common type, and they are compatible with most keycap sets. However, switches like Topre, Kailh, Gateron, and others may have different designs, requiring specific keycaps or adapters to ensure keycaps will fit your keyboard properly. Below is a table summarizing the key characteristics of popular switches:
| Switch Type | Features |
| Cherry MX | Most common, compatible with most keycaps, various tactile and linear options |
| Kailh | Similar to Cherry MX, offers unique Box switches for dust and water resistance |
| Gateron | Known for smoother keystrokes, Cherry MX-compatible, popular with people unlike the “scratchy” |
| Topre | Uses a rubber dome mechanism, not compatible with Cherry MX keycaps without adapters |
| Razer | Designed for gaming, tactile and clicky options, usually only compatible with Razer keycaps |

The layout of a keyboard determines the size and position of each key, which directly impacts keycap compatibility. Different layouts can require different keycap sizes, especially for larger or less common keys like the enter, shift, and spacebar. Standard layouts are the most common and typically follow established formats like ANSI, ISO, and JIS. These layouts generally make it easier to find compatible keycap sets:
Whether you're after comfort, speed, or a sleek minimalist setup, this guide on keyboard sizes and layouts will help you make the right choice.
Keycap material plays a significant role in durability and feel. The most common materials are ABS and PBT. ABS keycaps are affordable and smooth but tend to become shiny over time. In contrast, PBT keycaps are more durable and resistant to wear, offering a matte texture that doesn’t develop shine as quickly.
Quality also matters when choosing keycaps. Well-made keycaps will fit securely on switches, ensuring stability during typing. Poorly manufactured keycaps, regardless of material, may have fitting issues, causing them to feel loose or wobbly. Always opt for high-quality keycaps to avoid potential compatibility and performance problems.
Stabilizers are created to keep the keys from shaking, rattling, and tilting when typing or gaming. You easily see them under the larger keys such as space bar, backspace, and shift when switching keycaps. This is one of the key features that decides if your keycaps will fit your keyboard. We've listed a few common stabilizer types out there below:
When looking for a new keycap set, you will want to make sure the set thickness, material, and profile are suitable for the backlight. For example, if you are using RGB lighting, then you will need keycaps that are double-shot, clear, or pudding style to allow the light to shine through. So, don't forget to check if your new keycaps are backlit support or not.
Identifying your keyboard's switch type is important for keycap compatibility. You can find this information in the user manual or by contacting the manufacturer. Most keyboards utilize Cherry MX-style switches with a "+" cross-shaped stem, ensuring compatibility with a wide range of keycaps.
However, if your keyboard uses a different switch type, finding compatible keycaps that match your aesthetic preferences might be more challenging.
The keycap profile covers the shape and height of the keycaps. Many manufacturers clearly state the profile (e.g., Cherry, OEM, SA) on the product packaging. Choosing the right profile not only affects aesthetics but also the typing experience. Consider your preference for a flat or sculpted profile, and ensure compatibility with your keyboard and switch type.
* Note: The best compatibility is south-facing keyboards due to the interference between the keys when using Cherry-profile keycaps with north-facing keyboards.
Before purchasing keycaps, determine your keyboard's layout (ANSI, ISO-DE, JIS). Standard layouts (ANSI) are most common, but some keyboards have variations in key size and arrangement. Verifying your layout ensures the keycaps you choose have the correct configuration, particularly for keys like Enter, Shift, and Backspace.
To check keycap compatibility with your keyboard, you can use several online resources. Forums and knowledge bases like Deskthority and Geekhack are great places where enthusiasts share detailed specifications. The Reddit mechanical keyboard community is also excellent for asking questions and getting recommendations. Additionally, many websites that sell keycaps provide detailed specifications on their product pages. Always review these details before purchasing to ensure a perfect fit.
