Pro Tips

1

Screed your 1-inch sand layer using two parallel 1" steel conduit pipes as rails. Drag a straight 2x4 across them for a perfectly flat paver surface.

2

Use Quikrete Play Sand (#1113) or Sakrete Natural Play Sand for sandboxes. Both are pre-washed, ASTM C33 certified, and low-dust.

3

Compact sand in 2-inch lifts maximum using a plate compactor. A single thick pour won't compact evenly and settles unevenly within weeks.

4

For paver projects, sand is only one layer. Use our Paver Base Calculator to estimate the crushed stone base layer underneath.

5

Need gravel instead of sand for your project? Our Pea Gravel Calculator handles pathways and decorative coverage estimates.

6

In cold climates, avoid laying polymeric sand after October. It needs 24 hours above 32°F to cure or it washes out with spring rain.

How the Calculator Works

This calculator factors in the actual density of each sand type. Play sand at 1.3 tons per cubic yard is noticeably lighter than polymeric sand at 1.45 tons per cubic yard, and ordering by weight when you should order by volume is one of the most common mistakes. The compaction factor matters too: sand loses 15 to 25% of its volume when compacted, so a 1-inch finished bedding layer requires about 1.2 inches of loose sand. The reverse mode (tons to area) lets you enter what you have and see how much ground it covers.

Formula

Length × Width × (Depth ÷ 12) = Cubic Feet

Cubic Feet ÷ 27 × Density = Tons needed

Add waste factor for final amount

Frequently Asked Questions About Sand

How much sand do I need?

Multiply length x width x depth (in feet) for cubic feet, then divide by 27 for cubic yards. A 10x10 patio at 1-inch depth needs about 0.37 cubic yards. Add 10 to 15% for compaction.

How much does a yard of sand weigh?

One cubic yard weighs 2,600 to 3,000 lbs (1.3 to 1.5 tons) dry. The Concrete Network's sand guide notes wet sand can weigh 20 to 30% more, which matters for truck payload limits.

Play sand vs masonry sand?

Play sand is kiln-dried and screened for child safety (ASTM C33). Masonry sand is coarser with angular grains for mortar mixes, too rough for sandboxes.

How deep should a sandbox be?

CPSC recommends 12 inches minimum for fall protection. For basic sandboxes without climbing structures, 8 to 10 inches works.

Polymeric sand for all paver joints?

It works best in joints 1/16" to 1.5" wide. Narrower joints won't fill properly; wider joints may crack. Use gator dust for joints over 1.5".

How deep should sand be under pavers?

1 inch screeded over compacted gravel for patios (ICPI standard). For driveways, use 1 to 1.5 inches over a 6-inch aggregate base.

Bagged or bulk sand?

Bulk costs $20 to $45/ton. Bags run $160 to $240/ton equivalent. Bulk saves 60 to 75% for anything over 0.5 cubic yards.

What about gravel for drainage?

For drainage layers under sand beds, our Stone Calculator estimates crushed stone quantities, and the French Drain Calculator covers full drainage system materials.

Sand Estimates for Common Projects

Backyard Sandbox

8×8 ft, 12" deep
Type: Quikrete Play Sand #1113Amount: 1.85 cu yd (~2.4 tons)Cost: $77

12 inches deep per CPSC safety guidelines. At bulk play sand pricing of $32/ton, this is about one-third the cost of buying forty-eight 50-lb bags from a big box store at $5 each ($240). Request delivery to your backyard if possible. Moving 2+ tons by wheelbarrow takes 30+ trips.

Paver Patio Bedding

12×20 ft, 1" deep
Type: Paver/Leveling Sand (ASTM C33)Amount: 1.1 cu yd (~1.5 tons)Cost: $63

1-inch screeded bedding layer with 15% compaction factor. You'll also need about two 50-lb bags of polymeric sand ($50) for the joints. Rent a plate compactor from Home Depot ($85/day). Hand tamping a 240 sq ft patio takes five times longer and won't compact evenly.

Driveway Paver Base

10×40 ft, 1.5" deep
Type: Masonry Sand + Polymeric JointsAmount: 2.75 cu yd (~3.7 tons) + 6 bags polymericCost: $291

1.5-inch bedding layer for vehicular traffic with 20% compaction factor. Driveway pavers require a thicker sand bed and a 6-8 inch compacted aggregate base beneath. Budget an additional $400-600 for the crushed stone base layer. Use our Paver Base Calculator for that estimate.

Sand Mistakes That Cost You Money

Wrong sand type for paver joints

Regular sand washes out within months. Use polymeric sand with polymer binders that harden when activated with water.

Not accounting for compaction loss

Sand compresses 15 to 25% under a plate compactor. A finished 1-inch layer requires 1.2 to 1.25 inches of loose sand.

Ordering by volume when supplier sells by weight

Wet sand weighs up to 30% more than dry. Confirm moisture conditions or you may get fewer cubic yards than expected.

Skipping the gravel base under pavers

Sand alone shifts under load. Pavers need 4 to 6 inches of compacted crushed stone beneath the sand bedding layer (ICPI standard).

Spreading sand too thick in one lift

Compactors only work in 2-inch lifts. A 6-inch fill needs three separate passes to avoid voids and uneven settling.

Activating polymeric sand on a damp surface

Even light dew causes premature bonding and white haze that is extremely hard to remove. Install only on completely dry days.
