You've settled on a colorway, chosen between PBT and ABS, maybe even picked out an artisan cap for that final touch. But there's one decision that changes everything about how your keyboard feels to type on — and many builders overlook it entirely.
Keycap profile.
It determines the shape, height, and row contour of every keycap on your board. It's the difference between typing on a set of uniform flat tiles and typing across a sculpted ergonomic landscape. And the best part? There's no universal "best" profile — just the one that fits your hands, your typing style, and your aesthetic.
In this guide, we'll break down every major keycap profile — Cherry, OEM, SA, XDA, DSA, and MDA — so you can find the perfect match for your next build.
What Is a Keycap Profile?
A keycap profile refers to the shape and height of a keycap. Unlike the material (PBT vs ABS), which affects sound and texture, the profile directly affects ergonomics and typing feel.
Profiles fall into two categories:
- Sculpted profiles — Each row of keys has a different shape and height. The home row (ASDF) sits lower, and the top and bottom rows curve upward. This creates a concave typing surface that follows the natural arc of your fingers, similar to how a piano keyboard curves around your hands.
- Uniform profiles — Every keycap on the keyboard shares the same shape and height. This lets you swap keycaps freely between rows, offers a flatter typing angle, and creates a clean, modern look.
The profile you choose affects three things: finger travel (how far your fingers reach), sound signature (taller caps = deeper sound), and aesthetic (retro, minimalist, classic).
Cherry Profile Keycaps
Profile type: Sculpted, low-profile
Row heights: R1 (bottom row) through R4 (top row)
Key features: Ergonomic, shorter height, vintage enthusiast classic
Cherry profile is named after Cherry MX and has been a staple in the mechanical keyboard community for decades. It's a sculpted profile with four distinct row heights that create a gentle curve following your fingertips' natural resting positions.
Why Enthusiasts Love Cherry Profile
- Shorter height — Cherry caps sit approximately 1–2mm lower than OEM, reducing the distance your fingers travel between keystrokes. Over a full workday, that adds up to noticeably less fatigue.
- Aggressive sculpt — The concave dish on each keycap cradles your fingertips. The top rows (R4 near the function row) have especially deep dishes for better grip when reaching upward.
- Clean aesthetic — The low profile gives keyboards a sleek, almost laptop-like silhouette that looks professional on any desk.
- Sound advantage — Cherry's shorter cap height can create a deeper, more controlled sound signature, especially on thick PBT sets. Paired with lubed linear switches, it's a combination that sound chasers swear by.
Cherry Profile vs OEM at a Glance
Cherry and OEM look nearly identical from the side, but the difference in height and sculpt is immediately noticeable when you start typing.
| OEM Profile | Cherry Profile | |
|---|---|---|
| Height | Taller (10–11mm) | Shorter (8–9mm) |
| Sculpt | Gentle, shallow curve | Aggressive, deeper concave |
| Dish depth | Shallow | Deep (especially on top rows) |
| Typing feel | Standard — what most pre-built keyboards ship with | Premium ergonomic — preferred by daily typists |
| Sound | Brighter "clack" | Deeper "thock" (especially thick PBT) |
| Availability | Widest — most common profile | Common in enthusiast-focused sets |
Who Should Choose Cherry Profile
- All-day typists — writers, developers, data entry professionals
- Keyboard enthusiasts who prioritize ergonomics over visual height
- Anyone building a board for sound quality — Cherry + thick PBT + lubed linears is a proven combination
- Users coming from low-profile or laptop keyboards who want a familiar reach

OEM Profile Keycaps
Profile type: Sculpted, medium height
Row heights: R1 (bottom) through R4 (top)
Key features: Industry standard, familiar feel, widest selection
OEM profile is the default profile found on most pre-built mechanical keyboards. If you've ever used a keyboard from brands like Ducky, Keychron, or Logitech, you've typed on OEM profile.
What Makes OEM Profile Special
- Widest availability — OEM is the most commonly produced profile, meaning you'll find the broadest range of colorways, themes, and price points
- Familiar feel — If you're new to custom keycaps, OEM feels immediately comfortable because it's what you're already used to
- Gentler curve — The shallower sculpt makes it a forgiving profile for typists who don't want an aggressive dish on every key
- Budget-friendly — OEM keycap sets tend to be the most affordable option, making them ideal for first-time builders
OEM vs Cherry: How to Tell Them Apart by Touch
Close your eyes and type on a keyboard. If your fingers feel like they're dipping into shallow bowls with a gentle slope, you're on OEM. If they feel securely cupped with a deeper dish and shorter overall reach, that's Cherry.
The practical difference matters most during long typing sessions. Cherry's shorter height and deeper sculpt reduce the micro-adjustments your fingers make on every keystroke — a subtle but meaningful ergonomic benefit over OEM.
Who Should Choose OEM Profile
- Beginners building their first custom keyboard
- Gamers who want maximum keycap availability and affordable options
- Users who prefer a taller, more traditional typing angle
- Anyone who wants the widest possible selection of designs and colors
SA Profile Keycaps
Profile type: Sculpted, tall
Row heights: R1 (bottom) through R3 (top) — SA typically uses three row shapes
Key features: Retro look, dramatic sculpt, legendary sound
SA (Spherical All) profile is the tallest popular keycap profile on the market. Instantly recognizable by its retro spherical top and towering height, SA turns a keyboard into a visual — and auditory — statement piece.
The SA Experience
SA keycaps are not for everyone. They sit significantly higher above the switch, changing your typing posture in a way that can feel fatiguing for some users. But the trade-off is worth it for enthusiasts who chase the legendary "SA thock."
- Deep, resonant sound — The extra height and thick walls create a rich, satisfying sound profile that's difficult to replicate with shorter caps
- Dramatic sculpt — The spherical tops and pronounced row curvature make every keystroke feel deliberate and weighty
- Retro aesthetic — SA is the closest modern equivalent to vintage IBM beam-spring and terminal keyboards, making it a favorite among vintage hardware enthusiasts
- Premium thickness — Quality SA sets (from manufacturers like Signature Plastics) are noticeably thick and heavy, built to last for years
Ergonomics Note
SA profile without a wrist rest can cause strain during long typing sessions. The increased height forces your wrists into a more extended position. If you're considering SA, we strongly recommend pairing it with a quality palm rest.
Who Should Choose SA Profile
- Sound enthusiasts — if "thock" is your priority, SA is the undisputed king
- Typists who type with a "floating" hand position (wrists off the desk)
- Builders who want a desk setup that makes a visual statement
- Retro keyboard fans who love the vintage IBM aesthetic
XDA Profile Keycaps
Profile type: Uniform, low-profile
Key features: Flat top, modern look, generous surface area
XDA profile is the uniform, low-profile alternative to sculpted keycaps. Every keycap shares the same shape and height, creating a perfectly flat typing surface with wide, spherical tops that give your fingers a generous landing area.
Why XDA Is Gaining Popularity
- Uniform profile — Any keycap fits any row, making it effortless to create custom layouts or ortholinear builds
- Generous surface area — The wide, flat tops give your fingers room to land without needing precision aiming — especially helpful if you have larger hands
- Modern, minimalist look — XDA's uniform flatness creates a clean, contemporary desk aesthetic that photographs beautifully
- Ortholinear-friendly — Uniform profiles shine on non-traditional layouts where sculpted rows would look and feel misaligned
XDA vs DSA
DSA is another uniform, low-profile option. The key difference: XDA has a larger surface area (approximately 18mm vs 14mm wide on a standard 1U cap) and sits about 1mm taller than DSA. XDA is the more forgiving option for imprecise typists; DSA is the more compact choice for minimalists.
Who Should Choose XDA Profile
- Ortholinear and split keyboard users (e.g., Planck, Corne, Lily58)
- Typists who prefer a flat, uniform surface over sculpted curvature
- Builders focused on desk photography and clean aesthetics
- Users with larger hands who benefit from the wide landing surface
DSA Profile Keycaps
Profile type: Uniform, ultra-low profile
Key features: Compact, flat, lowest height
DSA (Deep-dish Spherical Array) is the shortest uniform profile commonly available. It sits closer to the switch than almost any other profile, giving your keyboard an ultra-low, sleek profile that feels distinctly different from sculpted sets.
DSA Highlights
- Ultra-low height — At about 7mm, DSA is the shortest profile you'll commonly find, dramatically reducing finger travel
- Easy to swap — Uniform profile means you can rearrange cap positions freely without tracking row assignments
- Clean silhouette — The low, flat profile looks excellent on modern, low-profile keyboard designs
- Low-profile switch compatible — DSA pairs well with Kailh Choc and Gateron low-profile switch builds
Who Should Choose DSA Profile
- Low-profile keyboard enthusiasts
- Users who want maximum portability and a compact typing surface
- Ortholinear and ergonomic keyboard layouts where uniform height is essential
- Minimalists who prefer the cleanest, lowest-profile keyboard aesthetic
MDA Profile Keycaps
Profile type: Sculpted, medium height
Key features: The "Goldilocks" compromise profile
MDA (MelGeek Designed Aesthetic) profile sits between OEM and SA in both height and sculpt. It combines the ergonomic benefits of sculpted rows with a unique spherical top that feels distinctly different from the cylindrical dishes of Cherry and OEM.
What Makes MDA Special
- Spherical tops — Unlike Cherry/OEM cylindrical dishes, MDA uses spherical (dome-shaped) depressions, creating a different fingertip feel
- Middle-ground height — More sculpted than OEM, less extreme than SA
- Unique appearance — Stands out from the Cherry/OEM uniformity while remaining practical for daily typing
- Growing ecosystem — More manufacturers are starting to produce MDA-compatible sets
Who Should Choose MDA Profile
- Enthusiasts who want something distinctly different from the mainstream
- Users who find SA too tall but want more sculpt than Cherry offers
- Collectors who appreciate niche profiles with dedicated followings

How to Choose Your Profile
For All-Day Typing (Developers, Writers, Data Entry)
Cherry profile is the ergonomic winner. The shorter height and aggressive sculpt reduce finger travel and cradle your fingertips during marathon typing sessions. If Cherry feels too short, MDA provides a taller spherical option with similar ergonomic intent.
For Gaming
OEM profile is the safe choice — it's what virtually every gamer has used for years. The taller height provides tactile feedback that some gamers prefer for WASD movement. If you want a flatter, more consistent surface for competitive gaming, DSA or XDA give you uniform height across every key.
For Maximum Sound Quality
SA profile is the undisputed king of sound reproduction. Its tall, thick-walled caps produce a deep, resonant "thock" that keyboard enthusiasts chase for years. Cherry profile in thick PBT is a close second — more refined, less dramatic, but equally satisfying.
For Desk Aesthetics
XDA offers the cleanest, most modern silhouette for photography-heavy desk setups. SA brings retro character and visual weight. Your choice here is entirely about the visual statement you want your keyboard to make.
For First-Time Builders
Start with Cherry profile. It's the balanced, ergonomic choice that works for 90% of users — a safe entry point with proven performance. If you find Cherry too short, graduate to OEM or MDA. If you want maximum sound, graduate to SA. If you love flat, modern aesthetics, explore XDA.
Frequently Asked Questions
What is the most common keycap profile?
OEM profile is the most common, found on the vast majority of pre-built mechanical keyboards. Cherry profile is the most popular choice among custom keyboard enthusiasts.
Is Cherry profile better than OEM?
"Better" depends entirely on your preference. Cherry profile is shorter with more aggressive sculpting, which many daily typists find more ergonomic. OEM profile is taller with gentler curvature and offers the widest variety of designs. Try both before committing to one.
What is the best keycap profile for typing?
Cherry profile is widely considered the best for typing, thanks to its shorter height and deep concave dishes. For typists who prefer flat profiles, XDA's large surface area is also excellent.
Can I mix different keycap profiles?
Mixing profiles is common with artisan keycaps — a single SA artisan keycap on an OEM or Cherry set is perfectly fine and adds visual interest. However, mixing full rows of different profiles is not recommended, as height differences will create an uneven, uncomfortable typing surface.
What profile are standard keycaps?
Most keyboards ship with OEM profile. Some premium pre-builts (especially enthusiast-focused brands) use Cherry profile. Always check the product description — most custom keycap sellers explicitly mention the profile in their listings.
Where can I find Cherry profile PBT keycaps?
KeycapsHub carries a curated selection of Cherry profile PBT keycap sets that balance ergonomic design with premium materials. Browse the collection — or shop all keycap sets — for your next build.
Final Thoughts
Your keycap profile is one of the most personal decisions in any mechanical keyboard build. There is no objectively "best" profile. What matters is how it feels after three hours of typing, how it sounds to your ears, and how it looks on your desk.
If you're completely unsure where to start: begin with Cherry profile. It's the balanced, ergonomic choice that works for the vast majority of users. From there, explore — try an SA set for sound quality, build a flat XDA board for aesthetics, or stick with OEM for familiarity and selection.
