@am0sh_01 sorry, then my answer was not very useful. Around three cm maybe, could be more, could be less, depending on which material you use and how tight you knot 🙂
@rstring5 links can't be put in the comments unfortunately. I think MashaKnots doesn't have a video on this pattern specifically, but her video on the flat alpha technique is also very useful. You could also check out the video posted by @torres54
