If they don't, then 4 thick is usually standard for a patio slab, how large or small it is doesn't really matter. The most important part is the sub-base. Make sure you have a good gravel base. I would recommend at least 12 inches of compacted gravel. I like gravel where the aggregate (rocks) are no larger than 1.
For example, a 3Â½-inch-by-8-inch paver will cover a 28-inch area. Divide a square foot, or 144 inches, by the area the paver will cover. In the example of a 3Â½-inch-by-8 inch paver, divide 144 by 28 to get the number of pavers needed per square foot. In this example, 5.14 pavers will be required to cover 1 square foot of patio. Measure the area planned for the patio. Multiply the length times the width of the planned patio.
