For those exploring the world of mechanical keyboards, whether they are purchasing one for the first time or conducting research for a custom build, keycaps play a crucial role in determining both the keyboard’s aesthetic and its overall typing experience. The choice of keycaps significantly affects typing feel, sound, and style, making it essential to select a set that meets individual preferences and needs.
There are many factors to consider when evaluating keycaps, which can be overwhelming for newcomers or those not familiar with recent developments in the hobby. This guide is intended to provide a starting point for understanding keycaps, covering essential information.

Concerning keycaps, the primary consideration is ensuring they fit the specific keyboard in question. Without proper fit, compatibility issues arise, leading to mixed keycap usage. To begin, the ideal approach is to verify compatibility with MX-style switches, commonly found in modern keyboards due to their prevalent plus-shaped stem. Most keycap sets today are designed to fit these switches. However, some legacy keycaps from older keyboards may not be compatible with newer models.
Alternative switches also exist, such as Alps switches with minus-shaped stems, Topre (EC) switches with circular stems, and Kailh Choc low-profile switches featuring two prongs. Keycaps designed for these alternatives are not interchangeable with MX-style keyboards but are typically labeled for clarity.
Layout considerations are another key aspect. While many keyboards have standardized layouts, some, like the HHKB Studio, boast unique key arrangements, including distinctive G, H, and B keys and a shorter spacebar absent in standard keycap sets. Some keycap collections offer specialized kits to accommodate less common layouts.
Ensuring comprehensive coverage is another point of focus. Despite most keycap sets including all necessary components for a full-size keyboard, some products have adopted a modular approach, such as selling number pads separately to reduce base prices. This trend is particularly noticeable in budget-friendly or customizable sets that may exclude arrows and function keys by default.
Regarding keycap profiles and shapes, choosing the right design impacts typing feel and comfort. Key factors include keycap height, sculpts, and variations across row shapes. It should be noted that keycap profiles lack a standardized naming system, with terms based on manufacturer conventions. Some names logically describe hybrid designs, while others take a more whimsical approach.
