The Essential Guide to Mechanical Keyboard Keycaps (Part 1): Basics and Beyond

Mechanical keyboard keycaps are more than just the surface you type on—they define the look, feel, and performance of your keyboard. Whether you're a seasoned enthusiast or a curious beginner, understanding keycaps is essential to unlocking the full potential of your mechanical keyboard. In this first part of our ultimate guide, we'll tackle some common questions to get you started.

Are keycaps universal?

The short answer is no; keycaps are not universally compatible across all keyboards. Compatibility depends on several factors, including switch type, keyboard layout, and keycap profile.

1. Switch Type Compatibility

The foundation of keycap compatibility lies in the switch type. The majority of mechanical keyboards utilize Cherry MX-style switches, which feature a cross-shaped stem. Keycaps designed for these switches are widely available and offer extensive customization options. However, keyboards with Topre, Alps, or other proprietary switches require specific keycap designs, limiting compatibility.

2. Keyboard Layout Variations

Keyboard layouts, such as ANSI (American National Standards Institute) and ISO (International Organization for Standardization), influence keycap size and arrangement. For instance, the Enter key differs between these layouts—rectangular in ANSI and L-shaped in ISO. Additionally, compact layouts like 60% or 75% keyboards omit certain keys, necessitating compatible keycap sets that accommodate these unique configurations.

3. Keycap Profile Differences

Keycap profiles refer to the shape and height of the keycaps, affecting both aesthetics and typing feel. Common profiles include SA, DSA, XDA, and Cherry, each with distinct characteristics. While profile preference is subjective, it's crucial to ensure that the chosen keycap profile aligns with your keyboard's design to maintain a consistent typing experience. 

In summary, keycaps are not universally compatible. When selecting keycaps, consider your keyboard's switch type, layout, and desired keycap profile to ensure a seamless fit and optimal typing experience. Always verify compatibility before making a purchase to avoid mismatches and enhance your keyboard setup effectively.

Where to buy keycaps?

When seeking to purchase keycaps, several avenues are available:

1. Official Brand Websites: Many reputable brands sell keycaps directly through their official websites. For example, Signature Plastics and Akko offer a variety of keycap sets catering to different preferences.

2. E-commerce Platforms: Global online marketplaces like Amazon and eBay host numerous vendors offering a wide selection of keycaps. These platforms provide access to both mainstream and niche products, allowing you to find keycaps that suit your specific needs.

3. Custom Keycap Services: For a personalized touch, consider services that allow you to design your own keycaps. Platforms like MaxKeyboard enable users to create custom keycap sets, offering a unique way to tailor your keyboard's appearance.

4. Community Group Buys: Engaging with mechanical keyboard communities can lead to group buy opportunities, where enthusiasts collectively purchase custom keycap sets, often at discounted rates. Platforms like Geekhack and Reddit's r/MechanicalKeyboards frequently organize such events, providing access to unique designs not typically available through standard retail channels.

Before making a purchase, ensure that the keycaps are compatible with your keyboard's switch type and layout to guarantee a seamless fit and optimal typing experience.

What are double shot keycaps?

Double-shot keycaps are crafted through a manufacturing process that involves molding two separate pieces of plastic together. In this method, the legend (the character or symbol on the keycap) is formed by one piece, while the main housing of the keycap is created by another. These two pieces are then fused, resulting in legends that are an integral part of the keycap, ensuring durability and resistance to wear over time.

How thick is a keycap legend?

The thickness of a keycap's legend—the character or symbol on its surface—can vary depending on the manufacturing process and design preferences. In double-shot keycaps, where two layers of plastic are molded together, the legend is typically formed by the thickness of the top layer, which is often around 1.5 mm.

This design ensures that the legends are durable and resistant to wear. In contrast, laser-etched or printed legends may have varying thicknesses based on the etching or printing technique used. It's important to note that the legend's thickness is generally consistent across a keycap set, maintaining uniformity in appearance and feel.

How should I store , organize, and protect my spare keycaps?

Proper storage of your spare keycaps is essential to maintain their condition and ensure they are easily accessible when you want to switch up your keyboard's look. Here are some effective methods to consider:

1. Transparent Storage Boxes

Investing in transparent storage boxes is a popular method among enthusiasts. These boxes allow you to see your keycaps at a glance, making selection easier. They also protect your keycaps from dust and scratches.

2. Dedicated Keycap Storage Trays

Keycap storage trays are specifically designed to hold keycaps securely. These trays often come with individual slots for each keycap, preventing movement and potential damage. Some trays are stackable, allowing for organized storage of multiple sets.

3. DIY Solutions

For those who prefer a personalized touch, creating a DIY keycap storage solution can be both cost-effective and tailored to your specific needs. Utilizing materials like foam boards or repurposing existing containers can result in a customized organizer that fits your collection perfectly.

4. Original Packaging

If you have space, storing your keycaps in their original packaging is an excellent way to keep them organized and protected. Original boxes are typically designed to hold keycaps securely and can be easily labeled for identification.

5. Labeling and Cataloging

Regardless of the storage method you choose, labeling and cataloging your keycaps can significantly enhance organization. Consider labeling each storage unit with details like the keycap set name, material, or profile. Maintaining a digital catalog with photos and descriptions can also help you keep track of your collection.

By implementing these storage strategies, you can ensure that your spare keycaps remain in pristine condition and are readily available for your next keyboard customization project.
