Keycap Profiles Explained: Cherry vs OEM vs XDA vs MDA vs SA [2026 Guide]

Your keycap profile affects how your keyboard feels more than almost any other factor. It determines the height of every key, the angle of the top surface, the sound, and even your typing speed and comfort. This guide covers every major profile with measurements, comparisons, and recommendations.

What is a Keycap Profile?

A keycap profile defines the shape and height of your keycaps. Most profiles are "sculpted" — meaning each row has a different height and angle to match the natural curve of your fingers. Some profiles are "uniform" — every key is the same height.

The profile does NOT affect compatibility. All standard profiles use the same Cherry MX cross-shaped stem. You can swap between any profile on any MX-compatible keyboard.

All Profiles at a Glance

Profile Type Max Height Top Surface Sound North-Facing Safe? Best For
Cherry Sculpted 9.4mm Cylindrical, angled Deep, muted ⚠️ No Typing, gaming

SA Sculpted 16.5mm Spherical, deep dish Deep, resonant ✅ Yes Retro aesthetics, sound
DSA Uniform ~7.6mm Spherical Light, high-pitched ✅ Yes Low profile, portability

Cherry Profile — The Enthusiast Standard

Cherry profile is the most popular choice among keyboard enthusiasts. Originally designed by Cherry GmbH (the company behind Cherry MX switches), it has become the de facto standard for premium keycap sets.

Specifications

Row Height Angle
R1 (Function/Number) 9.4mm 0°
R2 (QWERTY) 7.9mm 2.5°
R3 (Home row) 6.6mm 5°
R4 (Bottom row) 6.3mm 11.5°

What Makes Cherry Special

  • Lowest sculpted profile — your fingers barely have to move between keys
  • Ergonomic sculpt — each row is angled to meet your fingers naturally
  • Cylindrical top — the top of each key has a subtle concave curve along one axis, guiding your fingers to the center
  • The "enthusiast choice" — most premium keycap group buys and designs use Cherry profile

Sound

Cherry profile produces a deeper, more muted sound compared to taller profiles. The low height means less internal air space, resulting in a tighter, thockier sound. This is especially noticeable with thick PBT Cherry sets.

The North-Facing Interference Issue

Cherry profile's main drawback: on keyboards with north-facing switches, the keycap's lower wall can physically hit the switch housing before bottoming out. This creates a mushy feel and altered sound.

If your keyboard has north-facing switches, you have two options:

1. Choose a different profile (OEM, XDA, MDA — all interference-free)

2. Look for Cherry sets designed to avoid interference (some manufacturers have adjusted the wall geometry)

Who Should Choose Cherry?

  • Long-session typists — the low height reduces fatigue
  • Gamers — fast actuation, minimal finger travel
  • Enthusiasts — the widest range of premium designs available
  • Anyone with south-facing switches

Our Cherry profile picks:

OEM Profile — The Familiar Default

OEM is the profile most people have used without knowing it. It's the standard on the vast majority of pre-built keyboards from brands like Razer, Corsair, Logitech, Ducky, and more.

Specifications

Row Height Angle
R1 (Function/Number) 11.9mm 3°
R2 (QWERTY) 10.6mm 7°
R3 (Home row) 9.5mm 8°
R4 (Bottom row) 9.3mm 10°

What Makes OEM Different from Cherry

  • Taller — 2-3mm higher per row than Cherry
  • Steeper angles — the sculpt is more gradual but the overall slope is taller
  • More forgiving — the extra height means no north-facing interference
  • Most familiar — if you've ever used a stock keyboard, you've used OEM

Sound

OEM profile produces a slightly higher-pitched sound than Cherry due to the taller internal air cavity. It's still a pleasant sound — not as clacky as SA, not as muted as Cherry. A good middle ground.

Who Should Choose OEM?

  • Beginners — feels immediately familiar, no adjustment period
  • People upgrading from a stock keyboard — same feel, better quality
  • North-facing switch users — zero interference
  • Anyone who doesn't want to "learn" a new profile

Our OEM profile picks:

XDA Profile — Clean, Flat, and Uniform

XDA is a uniform profile — every key is the same height and shape, regardless of which row it's in. This gives it a distinctive flat, clean appearance.

Specifications

All Rows Height Top Surface
Uniform ~9.8mm Flat with slightly rounded edges

What Makes XDA Unique

  • Uniform height — every key is identical. You can move any key to any row
  • Flat top surface — wider landing area for your fingers
  • No sculpting — the keyboard looks completely flat from the side
  • Comfortable for hovering typists — if you don't rest your wrists and "hover" over the keyboard, XDA feels natural
  • Zero north-facing interference — safe for any switch orientation

Sound

XDA produces a medium-pitched, consistent sound across all rows. Because every key is the same height, the sound is more uniform than sculpted profiles. PBT XDA sets have a pleasant, even tone.

The Adjustment Period

If you're coming from Cherry or OEM, XDA will feel different at first. The flat surface means your fingers don't have row-height cues to guide them. Most people adapt within a few days.

Who Should Choose XDA?

  • Aesthetics-focused builders — the flat, uniform look is very clean
  • North-facing switch users — zero interference guaranteed
  • People who rearrange keycap legends (Dvorak, Colemak users)
  • Anyone who wants a wider key surface area

Our XDA profile picks:

MDA Profile — The Comfortable Middle Ground

MDA (sometimes called MG or MITO profile) is a sculpted profile that sits between Cherry and SA in height. It's become increasingly popular as a "best of both worlds" option.

Specifications

Row Approximate Height
R1 (Function/Number) ~11.5mm
R2 (QWERTY) ~10.5mm
R3 (Home row) ~9.8mm
R4 (Bottom row) ~9.5mm

What Makes MDA Stand Out

  • Medium height — taller than Cherry, shorter than SA
  • Spherical top surface — the top of each key is scooped in both directions, cradling your fingertip
  • Sculpted rows — like Cherry, each row has different heights for ergonomic finger positioning
  • No north-facing interference — safe for all switch orientations
  • Wider keycap tops — more surface area than Cherry, giving a comfortable "sitting in a bucket" feeling

Sound

MDA sounds rich and full — deeper than OEM, with more resonance than Cherry due to the slightly taller profile. The spherical tops and medium height create a satisfying, well-rounded acoustic signature.

Who Should Choose MDA?

  • People who want sculpted comfort WITHOUT north-facing interference
  • Anyone who finds Cherry too low but SA too tall
  • Comfort-focused typists who value the spherical top cupping
  • People looking for a unique, less common profile

Our MDA profile picks:

SA Profile — Tall, Retro, and Resonant

SA (Signature Plastics' "Spherical All") is the tallest commonly used profile. It's known for its retro aesthetic reminiscent of old typewriters and early computer terminals.

Specifications

Row Height Top Surface
R1 16.5mm Deep spherical dish
R2 14.9mm Deep spherical dish
R3 13.5mm Deep spherical dish
R4 13.5mm Deep spherical dish

What Makes SA Distinctive

  • Very tall — significantly taller than any other common profile
  • Deep spherical dish — the top of each key is deeply scooped, cradling your fingertip
  • Retro aesthetics — looks like a classic typewriter or vintage terminal
  • Heavy — the tall keycaps are heavier, changing the feel of each keypress
  • Zero north-facing interference — so tall that interference is impossible

Sound

SA has the deepest, most resonant sound of any common profile. The tall cavity creates a rich, echoing "thock" that many enthusiasts love. SA on a well-built keyboard sounds like no other profile.

The Trade-Off

SA's height is a double-edged sword:

  • Pro: Unique feel, amazing sound, retro aesthetics
  • Con: Increased finger travel means slower typing for some people
  • Con: Can cause wrist strain if you don't use a wrist rest
  • Con: Not ideal for fast-paced competitive gaming

Who Should Choose SA?

  • Retro aesthetic lovers
  • Sound enthusiasts who want the deepest possible thock
  • Casual typists who value feel over speed
  • People who use a wrist rest

DSA Profile — Low and Uniform

DSA (also by Signature Plastics) is a uniform profile like XDA, but shorter and with a spherical top surface.

Specifications

All Rows Height Top Surface
Uniform ~7.6mm Spherical (slightly scooped)

Key Characteristics

  • Very short — the lowest uniform profile
  • Spherical tops — slightly scooped, unlike XDA's flat tops
  • Uniform — all rows identical
  • Lightweight feel — short and light
  • Zero north-facing interference

Who Should Choose DSA?

  • People who want the lowest possible uniform profile
  • Travel keyboard users
  • Those who prefer spherical tops over XDA's flat tops

Head-to-Head Comparison

Height Comparison (Tallest Row)

Profile Height Relative
DSA 7.6mm Shortest
Cherry 9.4mm Low
XDA 9.8mm Low-medium
OEM 11.9mm Medium
MDA 11.5mm Medium
SA 16.5mm Tallest

Frequently Asked Questions

What is a keycap profile?

A keycap profile is the shape and height of the keycap. Different profiles have different heights per row, curvature, and top surface angles. The profile affects how the keyboard feels, sounds, and looks. Common profiles include Cherry, OEM, XDA, MDA, SA, and DSA.

What is the best keycap profile for typing?

Cherry profile is widely considered the best for typing. Its low height (9.4mm tallest row) reduces finger travel and fatigue during long typing sessions. The sculpted rows match natural finger positions. OEM is a close second with a more familiar feel for most people.

What is the best keycap profile for gaming?

Cherry profile is the most popular for gaming due to its low height and fast actuation. OEM is also excellent. Avoid tall profiles like SA for competitive gaming — the extra height increases travel distance and slows key presses.

What is the difference between Cherry and OEM profile?

Cherry profile is shorter (9.4mm max height) with a slightly more aggressive sculpt. OEM profile is taller (11.9mm max height) with a more gradual slope. Cherry feels more ergonomic for long sessions; OEM feels more familiar as it's the default on most stock keyboards. Both are sculpted profiles with different heights per row.

What is XDA profile?

XDA is a uniform profile where all rows are the same height and shape. The keys have a flat top surface with slightly rounded edges. XDA keycaps are compatible with north-facing switches (no interference) and have a clean, minimalist look. The uniform height means you can rearrange keys between rows.

What is MDA profile?

MDA is a medium-height sculpted profile that sits between Cherry and SA in height. It offers comfortable sculpted rows like Cherry but with slightly more surface area. MDA is compatible with north-facing switches and provides a nice balance between ergonomics and aesthetics.

Which keycap profiles work with north-facing switches?

OEM, XDA, MDA, SA, and DSA profiles all work with north-facing switches without interference. Cherry profile can cause interference on north-facing keyboards because its low height allows the keycap wall to hit the switch housing before bottoming out.

Can I mix different keycap profiles on one keyboard?

Technically yes — all MX-compatible profiles use the same stem. But mixing profiles creates uneven heights and feels awkward to type on. The only common exception is using a different profile artisan keycap on the Escape key.
