Keycap Profiles Explained: Cherry, OEM, SA, DSA, XDA, and MDA

Cherry, OEM, SA, DSA, XDA, and MDA

The number one question we get — before color, before material, before compatibility — is some version of: "what's the difference between all these profiles and which one should I get?" It's a fair question. There are a lot of profiles out there, they all have confusing names, and nobody wants to spend $40 on keycaps only to realize they hate how they feel. So let me walk you through each one. No fluff, just the stuff that actually helps you decide.

Two things to know before we get into the individual profiles:

Sculpted vs. uniform. Some profiles have different heights for each row — that's sculpted. Others are the same height across every row — that's uniform. Sculpted profiles are more ergonomic because they angle each row toward your fingers. Uniform profiles let you swap keys between rows freely, which is great for custom layouts.

Spherical vs. flat top surface. Some profiles have a slightly concave, curved top (spherical). Others are flat. The spherical ones center your fingertip naturally on each key. The flat ones feel more precise and are easier to clean. Both are valid — it's a feel preference, not a quality difference.

OEM Profile — The One You Already Know

Why this matters first

If you've ever used a stock mechanical keyboard straight out of the box, you've already used OEM. It's the most common profile in the world, which makes it your reference point and the thing you'll compare everything else against. Understanding OEM first makes every other profile easier to evaluate.

OEM stands for Original Equipment Manufacturer — the generic, default profile that ships on most pre-built keyboards. It's sculpted with medium height (~11.5mm on the home row), each row tilted at a slightly different angle to guide your fingers naturally. The top surface is flat with softly rounded edges.

I won't sugarcoat it: OEM is competent but not exciting. It works, it's familiar, and there's a reason it's the default. But once you've spent time with Cherry or MDA, coming back to OEM feels a bit like driving a rental car after you've driven your own.

Works well for
  • Complete beginners
  • Broad layout compatibility
  • Easy to find replacement sets
  • Zero adaptation period
Less ideal for
  • Long typing sessions
  • Enthusiasts wanting something distinctive
  • South-facing LED boards (legends obscured)
👤
Best for: people upgrading their first keyboard If you just want a new colorway without changing how your keyboard feels, OEM is the safe bet. Familiar feel, wide selection, no surprises. Browse our full range at norikeys.com/collections/all.

Cherry Profile — The Enthusiast Standard

Why this matters first

Cherry is the profile most keyboard enthusiasts eventually land on. It's lower, more precise, and once you've typed on it for a few days, going back to OEM or SA feels wrong. But Cherry has one real catch that trips up a lot of first-time buyers — and if you don't know about it before you buy, you'll be unhappy with your purchase.

Cherry profile is shorter than OEM (~9.2mm on the home row) and has a more aggressive row-to-row angle that pulls your fingers into a very natural typing position. The reduced height means less finger travel, which adds up significantly over long sessions. Most enthusiasts describe Cherry as "just feeling right" after a brief adjustment period.

The catch: Cherry profile was designed for south-facing switches (LEDs at the bottom of the switch). On north-facing switches (LEDs at the top, common on many modern boards), the keycap wall can clip the switch housing before fully bottoming out. This causes a slightly different sound and, for some people, a tactile click-before-click sensation.

North-facing switch check: If your keyboard has RGB that shines through the top of the keycap, you probably have north-facing switches. In that case, Cherry profile may cause slight interference. OEM, XDA, MDA, SA, and DSA don't have this issue. When in doubt, go MDA.
Works well for
  • Daily typing — documents, code, email
  • Touch typists
  • South-facing switch keyboards
  • Enthusiasts who want best-in-class ergonomics
Less ideal for
  • North-facing switch boards (check first)
  • Beginners wanting zero adjustment period
👤
Best for: daily typists on south-facing keyboards If you write a lot and your board has south-facing switches, Cherry is probably your end-game profile. Confirm your switch orientation before ordering — it takes 30 seconds and saves a headache.

SA Profile — The Bold One

Why this matters first

SA is the profile people either love immediately or find completely impractical. It's dramatically taller than everything else on this list, sounds unlike any other profile, and looks genuinely distinctive on a desk. The reason to understand SA is because it's tempting — the renders look incredible — but it comes with real trade-offs that aren't obvious from photos.

SA profile is tall, spherical, and sculpted. At ~14.5mm on the home row, it's nearly 60% taller than Cherry. The spherical top surface curves inward, centering your fingertip on each key. It was inspired by vintage typewriter key shapes, and typing on it does feel like using something from a different era — in the best possible way.

The sound is what converts people to SA. On a well-built keyboard, SA produces a deep, resonant thock that no other common profile can replicate. The tall internal cavity of each cap creates an echo chamber. If you've heard someone's keyboard described as "thocky" — they were probably using SA or something inspired by it.

The downsides are real. SA takes 2–3 days to fully adjust to. It's not great for gaming — the height slows down lateral finger movements. And the caps are physically heavier, which changes the acoustic behavior of the board in ways that aren't always predictable.

Works well for
  • Vintage and retro desk aesthetics
  • Typists who prioritize sound above all
  • North-facing keyboards (no interference)
  • Collectors and display builds
Less ideal for
  • Gaming (slow lateral finger movement)
  • People who want zero adjustment period
  • Low-clearance desk setups
👤
Best for: writers and collectors who prioritize sound and aesthetics If you type for pleasure as much as productivity, and you want a keyboard that sounds genuinely special, SA is worth the adjustment. Don't buy it as your main gaming keyboard.
Uniform

DSA Profile — The Clean Minimalist

Why this matters first

DSA is the first uniform profile on this list, and that changes how you think about keycaps entirely. Because every row sits at the same height, you can put any keycap anywhere — no more worrying about which row a cap belongs to. For custom layouts or anyone who likes rearranging their board, DSA opens up options that sculpted profiles don't.

DSA (Distributed Structure Alphabet) is a low, uniform DSA profile with a spherical top surface. Every row is identical in height and angle — no row-to-row sculpting. The overall height is shorter than Cherry, giving it a very flat, low-slung appearance on the keyboard.

The spherical top is DSA's main ergonomic feature. Even without sculpting, the concave surface still centers your fingertip naturally on each key, making it less fatiguing than a purely flat uniform surface. The sound on DSA tends to be higher-pitched and clackier — less internal cavity space means less resonance.

Honest warning: the uniform height can slow down touch-typing speed initially, because your fingers lose the row-to-row angle cues that sculpted profiles provide. Most people adapt within a week.

Works well for
  • Custom and non-standard layouts
  • Ortholinear keyboards
  • People who swap keycap positions often
  • North-facing keyboards
Less ideal for
  • Fast touch-typists relying on row angle cues
  • People who want deeper, thockier sound
👤
Best for: ortholinear boards and layout experimenters If your keyboard doesn't follow a standard staggered layout, or if you frequently rearrange your keys, DSA is the most flexible profile on this list.

Uniform

XDA Profile — The Modern Flat

Why this matters first

XDA has become one of the most popular profiles for aesthetics-driven builds, and the reason is simple: it looks incredibly clean. No sculpting, flat wide tops, uniform height across every row. On the right colorway, an XDA keyboard looks like a design object. Understanding XDA helps you decide whether you're optimizing for looks or for feel — because those two things are in slight tension here.

XDA is a uniform profile like DSA, but taller and with a flat top surface instead of a spherical one. Each key has a larger surface area than most other profiles, which gives it that wide, clean, slightly chiclet-adjacent look. It sits between DSA and OEM in height.

Because the top is flat rather than concave, XDA doesn't guide your fingertip as naturally as DSA or Cherry. Some typists describe it as feeling "slippery" at first — no natural landing groove. That said, many people never notice, especially light typists. And the visual payoff is real: XDA sets in the right colorway are genuinely beautiful.

Being a uniform profile, XDA inherits DSA's key-swapping flexibility. And because it's taller than DSA, it tends to have a slightly deeper sound — not thocky, but warmer than DSA.

Works well for
  • Minimal, clean desk aesthetics
  • Themed colorways and artisan mods
  • Custom layout flexibility
  • North-facing keyboards
Less ideal for
  • Fast touch-typists who rely on feel cues
  • Competitive gaming (less per-key feedback)
👤
Best for: aesthetic-first builders who want a modern, clean look If the visual identity of your keyboard matters as much as how it types, XDA is one of the most photogenic profiles available. Especially great for themed novelty sets.

MDA Profile — The One We Keep Coming Back To

Why this matters first

MDA is the profile I reach for when someone says "just tell me what to get." It fixes the main problem with Cherry (north-facing interference), avoids SA's steep adaptation curve, and gives you a spherical top surface that neither XDA nor OEM can offer. It's not the most dramatic choice, but it's probably the most balanced one on this entire list — and it's what we carry most of here at norikeys for good reason.

MDA is a sculpted profile with a spherical top surface — combining the row-to-row ergonomics of Cherry with the finger-centering feel of SA. At ~10.5mm on the home row, it sits between Cherry and OEM in height. The row sculpting is gentler than Cherry, so the adaptation period is minimal — most people feel comfortable within an hour.

The spherical top is what sets MDA apart from Cherry and OEM. Your fingertip lands in a slight concave bowl on every key, giving it a more tactile, grounded feel than flat-top profiles. It's not as dramatic as SA's sphere, but it's noticeable in a good way — fingers settle naturally without having to think about it.

MDA also works with north-facing switches without interference — something Cherry can't reliably promise. If you're not sure whether your board has north or south-facing switches, MDA is the sculpted profile that doesn't require you to check first. It just works.

On sound: MDA produces a medium-depth warmth. Not as resonant as SA, not as clacky as DSA — somewhere warm and satisfying in between. Most people who try MDA once don't want to go back to OEM.

Works well for
  • Long typing sessions
  • Both north and south-facing keyboards
  • Typists who want SA feel at lower height
  • Hybrid gaming and typing use
Less ideal for
  • Ortholinear / non-standard layouts (sculpted)
  • People chasing SA's dramatic sound
👤
Best for: most people, honestly Ergonomic sculpting, spherical top, works with any switch orientation, medium height. If you're not sure which profile to start with, start here. MDA is the profile that converts the most skeptics.

All Six Profiles, Side by Side

Here's the quick-reference version. If you've read this far, these numbers should now mean something concrete rather than just being specs on a listing page.

Profile Type Height Top surface North-facing safe Best for
OEM Sculpted ~11.5mm Flat ✓ Yes Beginners, stock replacement
Cherry Sculpted ~9.2mm Flat ⚠ Check first Daily typing, south-facing boards
SA Sculpted ~14.5mm Spherical ✓ Yes Retro aesthetics, sound lovers
DSA Uniform ~7.6mm Spherical ✓ Yes Ortholinear, custom layouts
XDA Uniform ~9.0mm Flat ✓ Yes Minimal aesthetics, themed sets
MDA Sculpted ~10.5mm Spherical ✓ Yes Most people, hybrid use

Still not sure? Answer two questions.

1. Do you type more than you game?
Yes → Cherry, MDA, or SA. The sculpting and ergonomics matter more for extended typing.
No → XDA or DSA. Consistent, low-friction feel across rows is better for fast lateral movement.

2. Do you have north-facing switches?
Yes → Avoid Cherry. Go MDA, OEM, XDA, DSA, or SA.
Not sure → Go MDA. It works on both, no checking required.
