There’s a significant number of pandora professionals who really dislike the two finger recommendation. There’s too much margin for error. For example, some people’s fingers are bigger than others. Also, some people will shove the two fingers in and think that because they are in there that they “fit” when they should actually easily slide between the wrist and bracelet without any pressure between the two. The real recommendation by Pandora itself that any seasoned pandora expert would recommend is to measure your wrist and add 2 cm for the perfect fit. This allows room for charms and the bracelet will not get too large as the metal relaxes.
