It depends.
I start by using water depth to calculate scope. Then the next issue is your snubber and where it attaches, and if it's a bridle. When I used a bridle, it was fed through 2 hawsuer pipes probably 8' back from the bow roller. So if the chain straightened out in a blow with 7:1 scope, the point where the chain entered the water was maybe 10' ahead of the bow roller. The other option if using a snubber is too spool excess chain out, maybe until it almost touches the bottom. This keeps the snubber hook pulled down and reduces the amount of scope required on normal days.
