Question RE keycap sizes from a noob.

[vision-quest]

How do you tell what size the keycaps are when buying caps and/or a new board? For example, I bought a KBD75v2, and I bought a set of keycaps (DSA High Contrast Granite), but it looks like some don't fit (shift, enter, backspace, one delete and one alt). As far as I can tell, neither the keyboard or keycap website has a picture listing the size of each individual key, so how is someone meant to know if the set will fit the keyboard you own? What am I missing here?

Everything is based of a unit(0.75in or 19.05mm) a 1U cap is every alpha, number or function key for example. You tell how large a cap is by how many units it is, so left shift for example is 2.25U(all keys increment in 0.25U steps) and right shift is 2.75U on most keyboards that use the ANSI layout.

For your board it looks like your right shift is 1.75U as it uses a split shift layout(the 1U next to it is subtracted from the usual 2.75U). Backspace, and enter should fit as that board uses the standard 2U and 2.25U respectively. The bottom row is not the standard ANSI layout so it won't work with sets that were made to support only up to a 104 ANSI layout.

Thanks. So do you just assume all keycaps are sold in a standard ANSI layout? I looked everywhere on the link where I bought the caps, and it doesn't seem to mention anything about their size:

I bought the base set, icon modifiers and text modifiers, but the left and right shift don't fit, same with the right backspace and right function, alt and ctrl. The right function, alt and ctrl makes sense with what you said about the bottom row, but I don't understand the others? I can't really tell with the enter yet because I did accidentally order the KBD75v2 in ISO layout instead of ANSI, which I'm having someone help me fix, but I thought that would only effect the right enter and "\", nothing else?

EDIT: a picture of the ones that won't fit even with the base, icon modifier and text modifier packs:

Ahh ISO would cause some issues, I didn't even know you could get the KBD75v2 in ISO. ISO changes the left shift to 1.25U as the \| key is moved next to it, and the enter key would have to be modified first boardside before you can use an ANSI enter on there.

For most in stock sets, ANSI is best to assume while GB sets are a different story. The kits you bought don't seem to support 1U bottom row modifiers unfortunately.
