Types and Features of High Profile Keycaps
There are several types of hypro-key caps.
profile name | feature | Manufacturer / Brand | remarks |
---|---|---|---|
SA (Spherical All) | Rounded spherical top, very high keycaps, graduated height sculptured | Signature Plastics | Typical hi-pro, retro look |
MT3 (Matt3o Profile) | Slightly lower than SA, deep spherical curve, thick and stable | Drop / Matt3o | Fusion of modern and retro |
KAT (Keyreative All Touch) | Lower than SA, close to MT3 but slightly flat, spherical curve | Keyreative | Attractive sound and keystroke feel |
HiPro (High Profile) | Genuine high profile for Topre keyboards (Realforce) | Topre / Realforce | For Topre switches only |
MDA (Mid-height DSA) | Intermediate profile lower than SA and higher than MT3, wide top for stability | Various | Midway between high pro and low, but slightly higher in classification. |
SA is still the most famous.
However, people often think that it is a bit too expensive.
In that light, I personally feel that the MT3 profile is an “acceptable range of tall” keycap profiles.
Here is a height comparison.
SA > MT3 > KAT ≒ MDA > DSS > OEM > Cherry
It is difficult to make a general statement because the sound varies depending on the material used, but we have the impression that many people are attracted to the unique nasal sound, which tends to have a “deep, throaty sound”.
