The math for a 22x200 driveway

Area: 22 × 200 = 4,400 sq ft.
Depth in feet: 4 ÷ 12 = 0.333 ft.
Cubic feet: 4,400 × 0.333 = 1,466.7 cu ft.
Cubic yards: ÷ 27 = 54.32 yd³.
Tons: × 1.35 = 73.3 tons.

About #57 stone

Since #57 is washed and open-graded, it moves a little underfoot. Many installers put it over a compacted base of a dense-graded stone rather than straight on soil. 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. Since the driveway carries car and truck traffic, a little extra depth is cheap insurance.

Ordering tips

Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
Delivery size. 80.7 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.

When to choose #57 stone

Works well for:

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

Think twice for:

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 14x28 area at 3 inches takes about 4.9 tons.
Weight used here: about 1.35 tons per cubic yard.

Common estimating mistakes

Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
