You're multiplying O(n) numbers, each of which is O(log n) digits long, so the result is O(n log n) digits long.

Usually, it seems to be either (n log n) or (n log n) - 1 digits.

And usually in this case I would leave of the O, as that usually refers to the performance of an algorithm in time or space. I suppose you could construe the number of digits to be "space" but multiplying O(n) numbers doesn't make that much sense.
