Keycap Profiles Guide
A keycap profile is the physical shape of a keycap: its height, the angle it sits at, and the curvature of its top surface. These three properties combine to define how a keyboard feels under your fingers more than almost any other variable. Two keyboards with identical switches and the same PBT material can feel completely different just because one uses Cherry profile and the other uses SA.
Profile diversity exists because typing feel is genuinely personal, and different keyboards serve different needs. The mechanical keyboard community has been refining keycap geometry since the 1980s, and each profile on the market today reflects a specific set of tradeoffs.
Top surface geometry
The curvature stamped into each keycap's face shapes how your fingertip makes contact with every keystroke. Cylindrical tops curve along one axis, forming a trough that channels fingers along columns and gives clean, defined edges between adjacent keys. Spherical tops scoop inward in all directions, cradling the fingertip for a more centered, deliberate landing. Flat tops maximize surface area with no guidance at all, closest in feel to a chiclet or laptop keyboard. Most people have a strong preference once they've tried all three, but it takes a few sessions on each to notice the difference.
Sculpted vs. uniform
The most fundamental split is between sculpted and uniform profiles. Sculpted profiles angle each row differently, following the natural arc of your fingers reaching across the keyboard. Uniform profiles keep every row identical, which matters for keyboards where keys aren't in their usual positions, like ortholinear or split layouts. Neither approach is objectively better. Sculpted profiles reward touch typists with tactile row differentiation; uniform profiles give you complete layout flexibility.
Height
Height is the variable most people notice first. Low-profile options like PFF sit at around 5mm, bringing the keytop close to the desk in a way that feels similar to a laptop keyboard. Mid-height profiles like Cherry and PBS land around 7–9mm, which is where most people find a comfortable balance between travel and control. Taller profiles like KAT push past 13mm and produce noticeably deeper, more resonant sound from the larger air cavity inside each cap.
Yuzu Compatibility
All profiles available on Yuzu use MX-compatible stems, so they work with the vast majority of mechanical switches on the market. PFF also supports a range of low-profile MX switches, including Kailh Choc V2, Gateron Low Profile, and Cherry Low Profile. Each profile page covers compatibility in detail, including any layout-specific considerations to know before you order.
Le profil Cherry est le profil standard en ce qui concerne les touches de clavier mécaniques. Il est sculpté, ce qui signifie que chaque row a une hauteur et une forme différentes pour permettre un confort de frappe maximal. Choisissez cette option si vous n'êtes pas sûr du profil que vous préférez.
Le profil KAM a été créé par Keyreative. Il est plat, ce qui signifie que toutes les rows ont la même hauteur et la même forme pour permettre une compatibilité maximale pour échanger des touches entre les rows et différents claviers. Choisissez cette option si vous connaissez KAM ou préférez la sensation de frappe de DSA/XDA qui sont des profils de touches de clavier plats similaires.
PFF is a cylindrical keycap profile designed specifically for low-profile mechanical switches. It addresses the unique requirements of low-profile keyboards while maintaining the tactile benefits of sculpted keycaps for improved typing experience.
PBS uses a combination of a cylindrical front and back with a spherical top scoop. The result is a wide scooped contact area at the top, which enables a comfy and ergonomic typing experience.
