How to Choose Keyboard Keycaps: Material and Height Guide
01. The Importance of Keycaps
Keycaps, though seemingly insignificant, are critical components that impact typing tactile feedback, aesthetics, and durability. High-quality manufacturers invest heavily in keycap design and materials to reflect craftsmanship.
02. Material Selection
ABS Plastic
Features: Non-toxic, low-temperature resistant (-40°C), and affordable. Common in entry-level keyboards but prone to oil shine over time.
PBT Plastic
Advantages: High hardness, anti-shine properties, and granular texture. More expensive but durable and ideal for tactile enthusiasts.
POM Material
Characteristics: Extremely durable with a cold, smooth finish. Rare in stock keyboards but known for longevity (e.g., Cherry G80-3000 series).
03. Keycap Height Options
OEM Height
Ergonomic design with slight curvature, widely compatible for most users.
Other Heights
- Cherry Profile: Shorter than OEM, ideal for prolonged typing.
- SA Height: Tall retro-style caps (18mm) but fatiguing for extended use.
- XDA/DSA: Uniform height for minimalist layouts, great for custom builds.
04. Key Considerations
Switch Compatibility
Pair tactile switches with thinner caps and linear switches with thicker caps for optimized feedback.
Personal Preferences & Budget
No material is universally superior—balance cost, texture preferences, and use cases. PBT suits durability seekers, while ABS offers budget-friendly options.
