https://www.youtube.com/watch?v=QDig2EMTYIo look here at Poppa Chubby how thick and short his fingers are and listen him play, don't understand which chord you mean which spreads out over 4 frets though? since you 've joined I guess you follow Lisa's lessons and only 2 months in I don't think that there are such chords to be learned already.

Been playing for 50 years now and met litterally thousends of people of all kinds and all sort of hands and fingers from who you absolutely didn't expect them to play the guitar because they had short and fat fingers but they could play really good so what you tell here looks like the lamest excuse I've ever heard to give up.
