12x12 base calculation
Area is 144 sq ft. At 4 inches deep, compacted volume is 48 cubic feet before allowance. With 10% extra, the order volume is 52.8 cubic feet, or 1.96 cubic yards.
Using the default density of 1.6 tons per cubic yard, 1.96 cubic yards becomes about 3.13 tons of aggregate base.
Buying by bags vs tons
Half-cubic-foot bags are convenient for small repairs, but a 12x12 patio can require more than 100 bags at a 4 inch depth. Bulk delivery normally becomes easier once the project passes a few tons.
Use bag count for store pickup planning and tons for supplier quotes.
