Schritt-für-Schritt Beispielrechnung

Beispiel: Installing a 10 ft × 20 ft crushed stone patio base with 3 inches depth and 10% compaction allowance.

01

Area: 20 ft × 10 ft = 200 sq ft.

02

Depth in Feet: 3 in ÷ 12 = 0.25 ft.

03

Volume: 200 × 0.25 = 50 cu ft + 10% compaction = 55 cu ft.

04

Cubic Yards: 55 ÷ 27 = 2.04 cubic yards.

05

Convert to Tons: 2.04 cu yds × 1.4 tons/yd³ = 2.85 tons.

Result: Order 2.85 tons (or ~3 cubic yards) of crushed stone.

Gravel Weight & Volume Formula

Total Tons = (Length [ft] × Width [ft] × Depth [in ÷ 12]) ÷ 27 × (1 + Buffer) × Density [tons/yd³]

Area is multiplied by layer depth in feet to get volume in cubic feet. Dividing by 27 gives cubic yards. Multiplying cubic yards by the stone density factor (~1.4 tons per yard) produces the total tonnage to purchase.

Formelvariablen

Volume — Cubic yards of loose aggregate before compaction
Density — 1.4 tons/yd³ for crushed limestone/granite; 1.3 tons/yd³ for pea gravel

Berechnungsgrundlagen

  • Crushed stone base compacts by roughly 10% to 15% when tamped or rolled.
  • Gravel suppliers typically sell bulk material by the ton or by the cubic yard.

Häufig Gestellte Fragen

Typische Fragen von Heimwerkern und RenovierernKiesrechner

How deep should driveway gravel be?

A new gravel driveway needs a total depth of 8 to 12 inches composed in layers: a 4–6 inch sub-base of coarse crushed stone (#3 or #4), followed by a 4-inch layer of #57 stone, topped with 2 inches of dense crusher run.

How many square feet does a ton of gravel cover?

One ton of gravel covers approximately 100 square feet at 2 inches deep, or about 50 square feet at 4 inches deep.
