Masonry Sand Calculator 2026: Cubic Yards, Tons, and Cost
Calculate the cubic yards, tons, and delivered cost of masonry sand needed for mortar mixing, paver bedding, or joint fill. Built on ASTM C144 density references for U.S. contractors and DIYers planning 2026 projects.

View Chart →Calculation Method
Volume from Area and Depth
Length times width times depth in feet gives cubic feet, then divided by 27 to get cubic yards per ACI standard volume conversion.
Weight from Density
Cubic yards multiplied by the selected density value converts volume into tons for bulk ordering purposes.
Waste and Cost Applied
The waste percentage is added to raw volume before pricing, then multiplied by the entered unit price and delivery fee.
Masonry Sand Density Reference
| Condition | Density (lb/cu yd) | Approx. Tons per Cu Yd | Notes |
|---|---|---|---|
| Dry, loose | 2,400 lb | 1.20 tons | Lower bound, freshly screened sand |
| Average, working figure | 2,600 lb | 1.30 tons | Standard estimating assumption |
| Wet, compacted | 2,700 lb | 1.35 tons | Upper bound, moist or settled sand |
Density range reflects typical mason sand bulk density variation cited across supplier technical data sheets and construction density references.
What ASTM C144 Requires for Masonry Sand
ASTM C144, Standard Specification for Aggregate for Masonry Mortar, sets gradation limits for natural or manufactured sand used in mortar. Section 4 of the standard requires the aggregate to pass a 3/8 in sieve at 100 percent and meet specific percentages passing progressively finer sieves down to the No. 100 sieve.
Section 5 addresses deleterious substances, capping friable particles and organic impurities that weaken mortar bond and long-term durability. Sand failing gradation limits under Section 4.1 and 4.2 may still be used if the resulting mortar meets the property requirements of ASTM C270, but this requires lab verification, not visual inspection.
Masonry sand differs from concrete sand in gradation and intended use. If you are estimating aggregate for a concrete pour rather than mortar or bedding, use the sand calculator or the full concrete mix calculator instead.
Example Scenario: Patio Paver Base
Job Inputs
Area: 20 ft x 15 ft = 300 sq ft
Depth: 2 in (paver bedding layer)
Density: 2,600 lb per cubic yard (average)
Waste factor: 10%
At $38 per ton delivered, material cost lands near $101, plus any separate delivery fee.
Job Inputs: Small Repair with Bags
Area: 6 ft x 4 ft = 24 sq ft
Depth: 1.5 in joint fill
Purchase format: 50 lb bags
Bagged sand makes sense here since bulk delivery minimums usually run 1 to 2 tons per order.
Common Estimating Mistakes
- Using concrete sand density and gradation figures for a mortar mix, which does not meet ASTM C144 requirements for masonry mortar aggregate.
- Ignoring depth unit conversion, mixing inches and feet without converting inches to decimal feet before multiplying.
- Assuming dry sand density applies to wet, freshly delivered sand, which can weigh 10 to 15 percent more per cubic yard.
- Ordering bagged sand for large areas where bulk delivery is significantly cheaper per ton.
- Skipping a waste factor on paver or joint fill jobs, which often need touch-up material after initial compaction settles.
Ordering and Delivery Notes
Bulk masonry sand typically runs $25 to $50 per ton or $75 to $150 per cubic yard delivered as of 2026, with regional variation driven by hauling distance and local supply. Bagged 50 lb sand runs $3 to $8 per bag at retail, useful for repairs but inefficient for anything over half a cubic yard.
Most suppliers set minimum delivery quantities, often 1 to 2 tons, and charge a flat delivery fee separate from material cost. Confirm truck access to the site before ordering, since standard dump trucks need clearance for a straight drop rather than a wheelbarrow relay.
If your project also needs cement or a full mortar ratio breakdown, check the mortar mix calculator and the cement calculator. For broader volume conversions across materials, the cubic yard calculator and material calculator handle general estimating tasks.
Frequently Asked Questions
A cubic yard of masonry sand weighs approximately 2,400 to 2,700 pounds, or 1.2 to 1.35 tons, depending on moisture content and grain density. Most estimates use 2,600 lb per cubic yard as a working average.
Masonry sand is a fine, washed sand meeting ASTM C144 grading limits, used for mortar and paver joints. Concrete sand has a coarser gradation intended for use as an aggregate component in concrete mix, not for mortar joints.
Bulk masonry sand runs approximately $25 to $50 per ton or $75 to $150 per cubic yard delivered as of 2026, with bagged 50 lb bags costing around $3 to $8 each at retail.
One cubic yard of sand weighs roughly 2,600 lb, so it takes approximately 52 bags of 50 lb sand to equal one cubic yard.
Sand quantity for mortar depends on the mix ratio. A Type N mortar mix uses about 6 parts sand to 1 part cement by volume, so total sand volume equals roughly 75 percent of total mortar volume needed for the job.
No. Unwashed or unspecified sand may contain organic material, clay, or improper gradation that violates ASTM C144 requirements and weakens mortar bond strength and workability.
Yes. Wet sand can weigh 10 to 15 percent more than dry sand due to absorbed moisture, and bulking can increase the apparent volume by up to 30 percent for damp, loose sand. Order slightly more or confirm moisture content with your supplier.
