I put one on a few months back, feels very similar width wise to standard, it only makes it a couple of mm thicker.
If I was to do it again I'd get a leather skyver to make it thinner around where the trim pieces go, that way it would sit a bit nicer without having to trim it down (luckily I didn't take off too much when doing the trimming!).
They seem to offer different versions in different places (Amazon, Ebay, AliExpress etc) so it's worth checking to see if the design you want is on one of them, although I believe you can message them and customize the materials and thread colour.
