do they only affect the individual keycaps or the profile of the whole board? like let’s say oem are sharp and XDA are rounded, but is there a difference between the height of the rows?
Check out the site https://www.keycaps.info/ it shows side profiles and keycap heights of common profiles.
oh very cool, ty :)
Different keycap profiles do make a difference between the height, yes. This blog post has some graphics that illustrate the height difference of some keycap profiles pretty well.
Height varies a lot between different profiles - check out the comparison on this page (some of those are for low profile switches but G20 and up are for standard MX switches): https://fantechworld.com/keycap-profiles-differences/ Additionally some profiles such as DSA, XDA, and KAM are uniform, meaning every row is the same shape (except for homing keys). Others are sculpted, meaning the height and angle varies between rows.
