How many cobblestones are needed?
A. Because the type and size of cobblestones used dictate the number of stones needed, there is no fail-safe method to determine how many will be required to cover a given area. For estimation purposes, 3½ to 4 Medium cobblestones will usually cover a square foot. Depending on which surface you choose to use (the worn surface or the rough surface), approximately 1 to 2½ Jumbo cobblestones will cover a square foot.
