Sand Fill Calculator

About the Sand Fill Calculator

Sand is used in countless construction and landscaping applications — from paver base and leveling beds to playground fill, pipe bedding, and concrete mixing. Unlike gravel or dirt, sand's fine particles provide a smooth, level surface and fill voids completely, making it ideal for bedding and leveling applications.

This calculator determines how much sand you need in cubic yards and tons based on the area and depth of your project. Sand density varies from 1.3 to 1.5 tons per cubic yard depending on type and moisture content. Dry mason sand is lighter, while wet fill sand is heavier. Knowing the difference prevents over- or under-ordering.

Whether you're filling a sandbox, laying a paver base, or bedding a utility pipe, This calculator helps you order the exact amount and plan your deliveries efficiently.

When This Page Helps

Sand is heavy and messy to handle, so ordering the right amount on the first delivery saves time, money, and cleanup effort. This calculator gives you volume in cubic yards and weight in tons so you can match whichever unit your supplier uses, plus an estimate for bagged sand if you prefer retail purchases.

How to Use the Inputs

1. Enter the area to be covered in square feet.
2. Enter the desired sand depth in inches.
3. Adjust the sand density for your material type (1.3–1.5 tons/yd³).
4. Review the volume in cubic yards.
5. Check the weight in tons.
6. Use the bag count if purchasing retail bags.

Example Calculation

Tips & Best Practices

• Use coarse concrete sand for paver leveling beds, not fine mason sand.
• Paver leveling sand should be 1 inch thick and screeded level with guide pipes.
• For pipe bedding, sand should extend 4 inches below and 6 inches above the pipe.
• Wet sand is heavier — plan for extra weight if ordering during rainy weather.
• Keep sand covered with a tarp during storage to prevent contamination and washout.
• Order 10% extra to account for spillage and uneven subgrade.

Types of Sand for Construction

Fill sand is the cheapest option for backfill and rough grading. Concrete sand (C-33) is washed and graded for use in concrete mixes and as paver bedding. Mason sand is finely screened for mortar joints and decorative use. Play sand is washed and screened to be safe for children.

Calculating Sand for Paver Beds

For pavers, you need a 1-inch sand bed over a compacted gravel base. Calculate the area in square feet, divide by 12 for inches to feet, then divide by 27 for cubic yards. A 300 sq ft patio needs about 0.93 yd³ of sand just for the leveling layer.

Sand Delivery and Storage

Bulk sand should be delivered onto a hard surface like a driveway and covered with a tarp. Don't store sand piles on slopes — they'll wash away in rain. Plan to use bulk sand within a few days to avoid weeds growing in the pile.

Sand as Pipe Bedding

Utility pipes (sewer, water, gas) are typically bedded in 4–6 inches of sand below and 6–12 inches above the pipe. The sand protects the pipe and allows even support. Calculate the trench volume (length × width × depth) minus the pipe volume for an accurate sand estimate.

Frequently Asked Questions

• How much does sand weigh per cubic yard?

  Sand typically weighs 1.3 to 1.5 tons (2,600–3,000 lbs) per cubic yard. Dry sand is lighter at 1.3 tons/yd³, while wet sand can reach 1.5+ tons/yd³. Mason sand and play sand average about 1.35 tons/yd³.

• What type of sand is used under pavers?

  Coarse concrete sand (also called bedding sand or C-33 sand) is used for paver leveling beds. It has a gritty texture that compacts well and doesn't shift under the pavers. Avoid using fine mason sand or polymeric sand for the base layer.

• How deep should sand be under pavers?

  A paver leveling sand bed should be 1 inch thick after screeding. This sits on top of a 4–6 inch compacted gravel base. The sand provides a smooth, level surface for setting the pavers.

• How much sand do I need for a sandbox?

  Most sandboxes need 4–6 inches of play sand. A typical 8×8 ft sandbox at 6 inches deep needs about 1 cubic yard of sand (approximately 1.3 tons or 26 fifty-pound bags).

• Is bulk sand cheaper than bagged?

  Yes, significantly. Bulk sand costs $25–$50 per ton delivered, while bagged sand at retail costs $3–5 per 50-lb bag — that's $120–$200 per ton. For anything over 1 cubic yard, bulk delivery is the way to go.

• Can I use sand as fill material?

  Sand can be used as fill but has limitations. It drains well and doesn't expand like clay, but it doesn't compact as firmly as gravel or engineered fill. It's suitable for pipe zones and drainage fill but not for structural fill under foundations.

• What is the difference between fill sand and mason sand?

  Fill sand is unscreened, inexpensive, and used for backfill and grading. Mason sand is finely screened, smooth, and used for masonry joints, sandboxes, and decorative applications. Mason sand costs 2–3× more than fill sand.

• How many 50-lb bags of sand make a cubic yard?

  It takes approximately 54 bags of 50-lb sand to make one cubic yard (based on 2,700 lbs per yd³). At retail prices, this makes bagged sand 3–5× more expensive than bulk sand.
