OEM profile keycaps don't match UHK keycaps

I’ve ordered 2-3 sets of keycaps marketed as OEM profile for my UHK, but when I add them to the keyboard, they’re a visibly different height from the UHK keys.

Is there some additional keycap profile information I should be including in my searches if I want my new keycaps to match the UHK ones? Thanks!

UHK’s default set is Cherry profile (Ah, indeed). Then it’s possible that rows are mixed up. It’s very difficult to find all the needed keys more than 1U with the correct row.

You can google a comparison chart like this one for reference.

That’s not what it says on the UHK Layout and Keycaps page:

Replacing keycaps

We use OEM profile keycaps

I have personally mixed UHK keycaps with OEM keycaps (Pudding), and they are the same profile.

Here’s an example photo for an issue I’ve had three separate times. The key on the left is a perfect match for the UHK R1 keys, the one on the right is the same key (5), marketed as OEM, but clearly not the same profile.

That’s funny how different people/producers index rows differently. Some have R1 on the bottom, some have them on the top.

According to this picture, they even interpret OEM differently. So no wonder that your R1 (or R4 – well, top-most one) is slightly different.

I can’t see the difference between the OEM’s in that picture, and in any case, they all have more of a vertical slant than the ones I keep buying by mistake.

The Filco ones are visibly different. But maybe they mixed them up.

Anyway, it would help if you gave a link to the set you bought. Sometimes in description they give information what profile exactly they used. There are so many of them these days.

I bought this one and it was exactly the same UHK came with.
