- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic yards: 528.0 × 0.333 ÷ 27 = 6.52 yd³.
- Tons: × about 1.4 tons per yard = 9.1 tons.

Building the carport base
Most steel carports can anchor into a compacted gravel pad with auger or rebar anchors. Make the pad slightly larger than the frame and keep it level so the frame goes up square.

Depth for vehicles
Use 6 inches of compacted stone if you park pickups or trailers under it; 4 inches is the minimum for cars on firm soil.
Buying the stone
Small dump trucks commonly carry around 5 to 10 tons and tri-axles more, but loads vary by truck and state, so ask the yard what fits in one trip. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. The scale ticket is the real weight; tons per yard here is a planning figure.
Common mistakes
The most frequent problem is ordering for the finished depth without allowing for compaction, which can shrink a loose layer by 10 to 20 percent. Another is skipping fabric on soft soil and watching the stone vanish into the mud over the first wet season. Spreading everything in one thick layer instead of compacted lifts also leaves a soft, rutted surface.
Measuring the area
Measure length and width in feet at a few points and use the largest figures, since real sites are rarely square. For odd shapes, split the area into rectangles and circles, work out each one and add them together. Depth is the number most people underestimate: drive a stake, run a level string and measure down to the dug-out surface in several spots.
