Why Use This Sand Calculator?
When laying patio pavers, building retaining walls, leveling above-ground pool liners, or mixing masonry mortar, sand provides the ultimate leveling course. However, ordering sand requires knowing whether to purchase bagged sand from a home improvement store or bulk sand by the ton from a quarry. This calculator converts cubic feet to cubic yards, tons, and 50 lb bag counts with compaction allowances.
Sand Volume & Conversion Formulas
\[\text{Depth (ft)} = \frac{\text{Depth (in)}}{12}\] \[\text{Net Volume (cu ft)} = \text{Area (sq ft)} \times \text{Depth (ft)}\] \[\text{Total Volume with Waste (cu ft)} = \text{Net Volume (cu ft)} \times \left(1 + \frac{\text{Waste \%}}{100}\right)\] \[\text{Cubic Yards} = \frac{\text{Total Volume (cu ft)}}{27}\] \[\text{Tons} = \frac{\text{Cubic Yards} \times \text{Density (lbs/cu yd)}}{2000}\] \[\text{50 lb Bags} = \left\lceil \frac{\text{Total Volume (cu ft)} \times \text{Density (lbs/cu ft)}}{50} \right\rceil\] \[\text{Total Bulk Cost} = \text{Tons} \times \text{Price Per Ton}\]Sand Coverage & Bag Reference Table (Paver Sand ~1.35 Tons/yd³, $40/Ton)
| Area & Layer Depth | Volume (cu ft) | Total Volume (+10% Waste) | Weight in Tons | 50 lb Bags Needed | Bulk Cost ($40/Ton) | Bagged Cost ($4.50/Bag) |
|---|---|---|---|---|---|---|
| 100 sq ft @ 1 in depth | 8.33 cu ft | 0.34 cu yds | 0.46 Tons | 18 Bags | $18.40 | $81.00 |
| 300 sq ft @ 1 in depth | 25.00 cu ft | 1.02 cu yds | 1.38 Tons | 55 Bags | $55.20 | $247.50 |
| 500 sq ft @ 2 in depth | 83.33 cu ft | 3.39 cu yds | 4.58 Tons | 183 Bags | $183.20 | $823.50 |
| 1,000 sq ft @ 2 in depth | 166.67 cu ft | 6.79 cu yds | 9.17 Tons | 367 Bags | $366.80 | $1,651.50 |
Step-by-Step Guide: How to Calculate Sand Bedding
- Calculate Surface Area: Measure patio, walkway, or sandbox length and width in feet.
- Select Bedding Thickness: Standard concrete paver installation requires exactly 1 inch of uncompacted sand bedding.
- Choose Sand Type: Use coarse concrete sand for paver bedding screed; use masonry sand for brick mortar.
- Determine Delivery Method: If needing over 15 bags of 50 lb sand, buy bulk delivery to save up to 75% on materials.
Frequently Asked Questions
How many tons of sand are in a cubic yard?
One cubic yard of dry sand weighs approximately 1.35 tons (2,700 lbs). Damp sand can weigh up to 1.50 tons per cubic yard.
How thick should the sand bed be under patio pavers?
Interlocking brick and concrete pavers require a uniform 1-inch (25mm) layer of coarse concrete sand screed over a compacted gravel base.
How many 50lb bags of sand equal 1 cubic yard?
It takes 54 bags of 50 lb sand to equal 1 cubic yard of sand.
What is the difference between concrete sand and masonry sand?
Concrete sand (paver sand) has coarse, angular grains ideal for paver bedding and locking joints. Masonry sand is finely washed and screened for smooth mortar mixing.
How many square feet does 1 ton of sand cover at 1 inch depth?
One ton of sand (approx. 0.74 cu yds) covers approximately 240 square feet at a depth of 1 inch.
When is bulk sand cheaper than buying 50lb bags?
For projects requiring more than 0.5 cubic yards (27 bags of 50lb sand), ordering bulk sand from a landscape supply yard is significantly cheaper.
