The math

  1. Area: 700.0 sq ft.
  2. Depth in feet: 6 ÷ 12 = 0.500 ft.
  3. Cubic yards: 700.0 × 0.500 ÷ 27 = 12.96 yd³.
  4. Tons: × about 1.4 tons per yard = 18.1 tons.

The gravel calculator does this for any size.

How thick to build it

Plan on at least 6 inches of compacted stone. Heavier motorhomes, wet sites or soft soil call for 8 to 12 inches. Fabric under the stone stops it from pumping into the mud over time.

Size and access

A 14-foot width gives comfortable room to open slide-outs and walk around the rig. Add a wider entry flare where the pad meets the driveway so you can swing in without cutting across the lawn.

Drainage

Build the pad a little higher than the yard and slope it gently. Standing water under an RV softens the base and invites rust.

Ordering and delivery

Most quarries and landscape yards deliver by the ton; ask whether there is a minimum and a delivery fee, and where the driver can dump without damaging your lawn. Gravel is a broad label, so confirm whether the yard means crushed or rounded stone and whether it carries fines. Round up by about 10 percent for compaction and uneven ground.
