EMA profile

The EMA keycap profile is an in-house development by IDOBAO. A sculpted, spherical profile.
Published November 10, 2022

IDOBAO announced the EMA profile along with a handful of first sets (set ideas?) of this sculpted spherical keycap profile.

The EMA keycap is a new profile that IDOBAO spent a year re-adjusting. We reduced the height to make it more in line with the typing habits of most people – IDOBAO.

Being spherical and sculpted, the profile is in the same league as SA, MT3, MDA, KAT, etc.

It seems the height is reduced compared to MT3 (and ofc SA), but it's higher than MDA caps (+1.5mm). The top surface is more spacious than that of the average cap, thus similar to MDA.


  • Profile: EMA
  • Height: 10.84-13.85mm
  • Width: 18.2 * 18.2 mm
  • Thickness: 1.5mm
  • Tech: Doubleshot
  • Material: PBT
  • Theme: Pure white / Pure Black / Elf of Winter
  • Keys: 141 keys


As I can see, some ABS versions are already available on, but this time it's about a PBT set.

If you want to help the vendor, here is an IC form.
