What Are OEM Keycap Profiles?
OEM (Original Equipment Manufacturer) keycap profiles represent the most widely used keycap shape in the mechanical keyboard world. These keycaps feature a cylindrical shape with a gentle curve that naturally follows the contour of your fingertips, making them the gold standard for both pre-built and custom mechanical keyboards.
The term “OEM” indicates these keycaps are designed as the original standard that most keyboard manufacturers adopt. This widespread adoption makes OEM profiles the most compatible and accessible option for keyboard enthusiasts.
Key Characteristics of OEM Profile
- Cylindrical top surface with slight curvature
- Medium height (taller than Cherry, shorter than SA)
- Row-specific sculpting for optimal finger positioning
- Stepped height design from bottom to top rows
- Wide compatibility across keyboard layouts
OEM Profile Specifications
Physical Dimensions
Design Features
Sculpting: Each row has a different angle and height to create a natural typing arc
Top Surface: Cylindrical with approximately 1mm depth curve
Wall Thickness: Typically 1.2-1.5mm for durability
Stem: Compatible with Cherry MX and clone switches
Why Choose OEM Profile Keycaps
1. Ergonomic Excellence
The sculpted design of OEM keycaps reduces finger strain during extended typing sessions. The cylindrical curve provides a larger surface area for your fingertips, distributing pressure more evenly than flat profiles.
2. Typing Accuracy
OEM’s row-specific heights create natural finger positioning that reduces typos. Your fingers naturally land in the correct position without conscious effort, improving both speed and accuracy.
3. Universal Compatibility
As the most common profile, OEM keycaps fit 99% of mechanical keyboards without compatibility issues. This makes upgrading simple and worry-free.
4. Balanced Feel
OEM strikes the perfect middle ground between comfort and tactile feedback. It’s not too high (like SA) or too low (like Cherry), making it ideal for both typing and gaming.
5. Cost-Effective Options
Due to widespread manufacturing, OEM keycaps offer the best value for money, with quality sets available at various price points.

Installation Guide
Tools Needed
- Keycap puller (wire or plastic)
- Clean workspace
- Soft cloth for cleaning
Step-by-Step Installation
Removing Old Keycaps
- Power off your keyboard and disconnect it
- Take a photo of your current layout for reference
- Use keycap puller to gently remove keys, starting from corners
- Work systematically row by row to avoid confusion
- Clean the switches with compressed air
Installing OEM Keycaps
- Identify row positions using the sculpted design
- Start with corner keys (Escape, Enter, Shift)
- Press down firmly until you hear/feel the click
- Test each key to ensure proper seating
- Install spacebar last – align stabilizers carefully
Pro Installation Tips
- Row 1: Function keys have the steepest angle
- Home row: Row 3 (ASDF) should feel most natural
- Spacebar: Ensure even pressure on both sides
- Stabilized keys: Check Enter, Shift, and Spacebar movement
