Keycap Compatibility
When it comes to customizing your keyboard with new keycaps, the first step is understanding what makes a keyboard a good candidate for this upgrade.
What Makes a Keyboard Compatible?
Compatibility hinges on several factors. The design of the key stems—the small posts underneath each keycap that connect to the keyboard itself—is crucial. Most custom keycaps are designed to fit a specific type of stem shape, typically a cross-like structure known as the MX style, which is common in mechanical keyboards.
Another factor is the size and layout of your keyboard. Keyboards come in various sizes, from full-size layouts with number pads to compact 60% layouts without them. Custom keycap sets are usually designed for standard layouts, so if your keyboard has an unconventional design or non-standard sizing for keys like the spacebar or enter key, finding replacements can be challenging.
Keycap Profiles and Sizes Matter
Beyond just fitting onto the stems, the profile of the keycap—its height and shape—is also important for compatibility. There are different profiles, such as flat, cylindrical, or spherical tops, and each offers a different typing experience and aesthetic.
The size of the keycaps must also match your keyboard’s layout. For example, if you have a larger-than-average escape key or a smaller backspace key, you’ll need to find custom keycaps that match those unique dimensions to ensure a perfect fit.
Making sure you have the right information about your keyboard’s layout and the type of stems it has will save you time and help you choose custom keycaps that will spruce up your workspace without any issues.
Keycap Fitment
Getting a set of custom keycaps to fit your keyboard is not just about aesthetics—it’s a precise science.
Stem Design
The stem is the part of the keycap that attaches to the keyboard’s switch. Most mechanical keyboards come with what’s known as an MX-compatible cross-shaped stem, but this isn’t universal. There are other types, like Topre or ALPS, which have different shapes and won’t accommodate MX-styled keycaps.
Before buying custom keycaps, take a moment to pop off one of your current keycaps (gently!) and observe the shape of the stem. This will determine the type of custom keycaps you can search for.
Size and Shape Considerations
Keycaps aren’t one-size-fits-all. They vary in shape and size to accommodate different fingers, typing styles, and aesthetics. These designs are referred to as profiles, which range from flat, uniform collections to contoured sets that change shape from row to row.
Understanding the profile of your existing keycaps and whether you want to maintain that feel or switch it up will guide your purchase. Remember, the incorrect profile might not only feel strange to type on but could also lead to compatibility issues.
Material Matters
Materials used in custom keycap production are varied, including ABS (acrylonitrile butadiene styrene) and PBT (polybutylene terephthalate), and even specialty plastics that can affect the keycap’s fit. For example, PBT is known for being tough and resistant to wear, which means it might feel more snug on a switch compared to ABS.
In your quest for the perfect set of custom keycaps, taking note of these materials can help you make an educated choice, ensuring a balance between form, function, and fit.
Mechanical vs. Membrane Keyboards for Custom Keycaps
| Feature | Mechanical Keyboards | Membrane Keyboards |
| Switch Design | Individual switches per key, allowing for a wide range of tactile feedback and sound profiles. | A single rubber sheet with domes; keys are typically part of this unit. |
| Keycap Customization | Each keycap is individually replaceable, fostering extensive personalization options. | Swapping keycaps is less practical due to design; limited customization options. |
| Materials Used | Keycaps made from durable materials like ABS or PBT, available in various textures and designs. | Often use cheaper materials and have fewer design options. |
| Stem Compatibility | Distinct stem designs (Cherry MX, Topre, Alps) that require matching custom keycaps. | Standardized stems if removable, but often not designed to be replaced. |
| Community Support | Robust aftermarket support with community-driven group buys and a wide variety of designs. | Limited community engagement in customization due to less practicality in replacing keycaps. |
| Performance | Preferred for consistent, precise keystrokes; optimized custom keycaps can enhance grip, ergonomics, and visibility. | Generally offer quieter but less consistent performance; wear out more quickly. |
| Durability | Custom keycaps tend to be high quality and long-lasting. | Stock keycaps may degrade faster and usually aren’t meant to be replaced. |
| Aesthetic Choices | Vast array of colors and artistic designs for expressing individual style. | Limited by the uniform design of the keyboard; few aesthetic enhancements possible. |
| Functionality | Layouts and keycaps can be customized for specific tasks, improving productivity through better ergonomics and shortcuts. | Typically not designed with customization in mind, leading to limited functionality changes. |
In simple terms, if you want to personalize your keyboard and make it unique, a mechanical keyboard is the way to go. You’ll have more choices and more support from other users. Membrane keyboards are better if you just want something basic that works.
Popular Types of Custom Keycap Mounts
MX-Compatible (Cross-Shaped Mounts):
- The most common type.
- Easy to find keycaps for.
- Fits on lots of different keyboards.
Topre (Circular Mounts):
- Less common, but some people really like them.
- Need special keycaps that are harder to find.
- You can get adapters to use more common keycaps.
Alps Mounts:
- Not as popular anymore.
- Have a unique shape that doesn’t work with the most common keycaps.
- Fewer options available, but still some out there for fans.
Buckling Spring Mounts:
- Old-school and not very common.
- Very hard to find custom keycaps for.
- Mostly just for specific classic keyboards.
Non-standard Rubber Dome Keyboards:
- Usually can’t change the keycaps at all.
- These are your typical cheap keyboards.
In summary, if you want to get custom keycaps, start with a keyboard that has MX-compatible switches since they have the most options. If you have a Topre, Alps, or buckling spring keyboard, it’ll be trickier to find keycaps, but not impossible. For regular, non-mechanical keyboards, you’re probably out of luck.
How to Check Your Keyboard’s Custom Keycap Compatibility?
Step 1: Find Out What Switches You Have
- Look for the switch brand name on your keyboard or in the manual.
- If you can’t find it, gently pull off a keycap and look at the stem—the plastic part that connects to the keycap. Most will have a cross shape.
Step 2: Measure Your Key Sizes
- Key sizes are usually standard, but measure them just in case, especially the bigger keys like the spacebar and enter key.
Step 3: Look at the Bottom Row of Keys
- The bottom row where the spacebar is can be different on some keyboards. Check if yours looks standard.
Step 4: Make Sure the Stems Match
- When you buy custom keycaps, they need to fit the stems on your switches. Make sure they match the stem shape you found in step 1.
Quick Tips:
- A keycap profile guide online can help you understand sizes and shapes.
- Ask on keyboard forums or communities online if you’re not sure about something.
- Some keycap sellers show which keyboards their caps will fit.
- Buy keycap sets with extra keys to make sure you have all the ones you need.
So before you buy custom keycaps, you just need to know what kind of switches you have and check that the keycap sizes and stems match what’s on your keyboard.
Understanding Keycap Compatibility for Keyboard Customization
While custom keycaps are a fantastic way to personalize your keyboard and enhance your typing experience, not all keyboards will support them. To ensure compatibility, it’s essential to know your keyboard’s switch type (like MX, Topre, or Alps), measure the sizes of your keys, and confirm that the bottom row has a standard layout. Mechanical keyboards generally offer the widest variety of customization options, with robust community support for personalization. On the other hand, membrane keyboards and non-standard layouts present significant limitations for custom keycap upgrades. By following these guidelines and double-checking stem designs before making a purchase, you can confidently select custom keycaps that will fit perfectly and reflect your personal style.
