Answer 1

Your local hardware or home improvement store likely has a range. It will be marked by use, not size. General purpose, cement, playground, etc.

Answer 2

Call your local sand and gravel company. Coarse sand is about 16 mesh, medium 30-50 mesh and fine 60 mesh and up. A "mesh" is a measure of the openings in wire screen. 16 mesh means 16 wires to the inch, etc.
