Most drillers will send in a sample of the sand, get back a recommended slot size and gravel pack size. 1"-2" thick gravel is usually enough, as long as it gets all the way around the casing. The slots should be slightly smaller than the gravel pack. The gravel should be slightly larger than the sand.
