How to Calculate Natural Stone Weights & Coverage for Your Project

When it comes to natural stone projects—whether you're building a wall, walkway, patio, or garden feature—knowing how much material to order is critical. At Wicki Stone, we help landscapers, masons, and homeowners determine how much stone they need & how much it will weigh by using easy calculations.

Weight Calculations: The Basics

To estimate the weight of your natural stone, you’ll need to understand a few simple formulas and material densities.

Stone Weight (Density) Per Cubic Foot:
- Bluestone & Karney – 165 lbs/cu ft
- Limestone – 165 lbs/cu ft
- Granite/Indian Hill – 175 lbs/cu ft

Formula:
Square Feet × Thickness (in feet) = Cubic Feet
Cubic Feet × Stone Density = Weight in Pounds
Example:
Let’s say you’re using 1.5" thick Blue Thermal Pattern Bluestone and want to cover 100 sq ft:
- 1.5" = 0.13 ft
- 100 sqft × 0.13 ft = 12.5 cu ft
- 12.5 cu ft × 165 lbs = 2,062.5 lbs (or just over 1 ton)

Stone Coverage by Type

Use the table below to estimate how much area (face feet or square feet) each ton of stone will cover.

ItemCoverage Per Ton
Normal Wallstone13 Face Feet
Normal 2' Boulders6 Face Feet
Pattern Patio/Walkway 1"220 sq ft **
Pattern Patio/Walkway 1.5"180 sq ft **
Irregular Flagstone at 1"115 sq ft
Irregular Flagstone at 1.5"80 sq ft
Irregular Flagstone at 2"70 sq ft
Gravel 1/8-3/4" (2" depth)100 sq ft
Gravel 1 - 3" (2" depth)75 sq ft
Building Veneer 3 - 4"37 sq ft
Building Veneer 4 - 6"35 sq ft
Belgian Block Standards40 sq ft (105 pieces)
Belgian Block Jumbos40 sq ft (70 pieces)
** Pattern Stone is sold by the square foot and not by weight. Exact square feet in a pallet varies.

Just plug in the quantity of tons to calculate approximate coverage based on the product type.

Example:
Normal Wallstone - you will be constructing a wall 26 feet long (x) 2 feet high = 52 square feet of face (the amount of stone you see when looking at the wall straight on).
Normal wallstone = 13 Face feet per ton.
52 Face feet needed / 13 face feet per ton = 4 tons (8,000 pounds)
Typical pallet = 3,000 pounds = 3 pallets (with some extra)

Palletized Stone Reference

Wallstone: 1 pallet ≈ 1.5 tons → Covers 18–20 face feet

Irregular Flagstone: 1 pallet of  2" thick ≈ 1.75 tons → Covers about 120 sq ft
