The math for a 16x200 driveway

Area: 16 × 200 = 3,200 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 3,200 × 0.333 = 1,066.7 cu ft.
Cubic yards: ÷ 27 = 39.51 yd³.
Tons: × 1.35 = 53.3 tons.

About #57 stone

#57 stone is a clean crushed stone in roughly the 1/2 to 1 inch range with very few fines. It drains fast, which suits drainage layers and the top of a gravel drive, but it does not pack into a hard crust by itself. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.

Preparing the driveway

Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. For car and truck traffic, the depths in the table above are a reasonable starting range.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 58.7 tons may take more than one typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
Bulk vs bags. At this size bulk delivery is usually the practical choice.
Where it drops. Have the truck dump as close to the driveway as firm ground allows.

Where #57 stone fits

Best suited to:

French drains and drainage layers
The top course of a gravel driveway
Under sheds where water needs to drain away

Less suited to:

A standalone base, since it does not pack hard without fines
Paver setting beds
Walk paths meant for strollers or wheelchairs

Quick reference numbers

Per inch over 100 sq ft: about 0.42 tons of #57 stone (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.2 tons.
Another size for comparison: a 20x25 area at 2 inches takes about 4.2 tons.
Weight used here: about 1.35 tons per cubic yard.

Mistakes that throw off the order

Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
