The best way to purchase gravel is in 40kg open misprint bags as it relatively easy to use to distribute over the working area. The size of gravel ranges between 13mm and 19mm, with some variation in stone size in between. You will require 1½ bag''s to cover a square meter (approximately 60kg). This should give you a thickness of about 3cm.
