There is a bit of slop as the chains will fit a range of tire sizes. People always recommend fitting the chain to make sure it fits even if it's new and the size on the bag Is the size you need. Better to find out now rather than on a hill in the snow.
Yeah 5 or 6 is a lot of excess to whip around. You can take the excess end and put it in the hook before you connect it to where it needs to be. To make a loop of the excess.

It is the "fitting" and "fit" I am asking about. There does not seem to be a standardized definition for what fit is. To throw your chains on and hope for the best is not the correct answer. If your chains do not fit, they may cause damage. If you lose a chain because it doesn't fit, you may get a ticket or be stuck on the side of a mountain or even cause you to wreck.
The circumference fit, to me is, easy. As long and you can catch a link without the cross chain overlapping
another cross chain you are good to go. Excess links can be tucked, bungied or secured so they don't flop and endanger people or equipment.
The side to side fit is the question. When the chain is centered on the tire, what is the optimal overhang? I would suggest it should overhang at least two inches and no more than half the distance between the edge of the tire to the rim. This is my own thinking and is not backed up by any manufacture's instructions or Federal or State law. To stay on the tire, it has to hang down a certain amount and the 1/2 distance from the rim will give you plenty of room as the tire circumference is reduced as the tire wears. -
I've honestly never put any real thought into it. Occasionally I lay my chains over my drives and check to see that they are long enough to hook and leave two or three links free and check to make sure I don't have any broken or loosening links. When I put my bungees or chain tighteners (stars) on for real I just grab up that bit of extra links with the S hook on the bungee. Never thought about how far it comes down over the sidewall and never thought it mattered, so long as they look secure. I've used a lot of hand-me-down chains (triple railers) and they seem pretty standard on how wide they are.
