I have a DURGOD Hades 68 keyboard that I’d love to spruce up with some custom caps. However, I’m not sure where to start with making sure a cap set will fit my board.
I’d really appreciate some advice on how to figure it out? Searching online hasn’t been that fruitful - or I’m not asking the right questions!
Are there any recommended stores for ISO layouts too?
Keycap sizes are pretty much standardized. The only thing you will need to keep an eye out for are your modifier keycaps (enter/shift/space/backspace/bottom row). Those are measured in "u" where 1u is an alpha key, so your modifiers might be 1.25u or 2u or the spacebar is 6.25u/7u normally. So when you find a keycap set you like just check that it includes the right number of mod sizes.
I took a quick look at the Hades68 keyboard and I couldn't find a specific link but I think this is the same sizing (from a tofu65)
I would guess 95% of keycaps sets will fit 98-99% of standard keyboards (60%-75%) with anything over 75% needing an additional numpad add-on set. Unless you're getting into some of the weird formats like 40% or ortho you probably won't need to worry too much.
Hope this makes sense. Let me know if you need any other clarification.
For you the row will only really apply to the right hand side since the "a" key will always be on row 3 and every key cap set will have "a" at the same height. The delete/home/end or whatever you decided to put on the right hand side above the arrow key will might be mismatched slightly but overall I don't think it's a big issue. On my keyboard my "r4" key is actually a "r3" key but it's close enough and it's only 1 key that's off.
KBDFans is probably the biggest store, but they do a lot of group buy stuff and sell extras after the group buy. You could do amazon, the massdrop/drop sets are a good starting place for keycaps. Otherwise most keycaps stores are specific to your country so for me in Canada I've got deskhero, ashkeebs and a couple others but the US has Kono, Canonkeys a bunch of others.
