Sand Calculator

Sand tonnage and 50 lb bag count for bedding, masonry and fill applications.

Quick answer: Dry sand weighs about 100 lb/ft³. Area × (depth ÷ 12) × 100 ÷ 2,000 = tons; a ton is forty 50 lb bags. Paver bedding uses exactly 1 in of concrete sand.

How to use this calculator

  1. Enter Length in ft.
  2. Enter Width in ft.
  3. Enter Depth in in.
  4. Enter Type.
  5. Enter Price per ton in $.
  6. Press Calculate. The highlighted row is your order quantity; the note beneath it translates the number into real-world terms.

Formula & constants

Dry sand weighs about 100 lb/ft³. Area × (depth ÷ 12) × 100 ÷ 2,000 = tons; a ton is forty 50 lb bags. Paver bedding uses exactly 1 in of concrete sand. Every default in the fields above is editable — when your supplier’s spec sheet lists a different density, coverage rate or price, enter that number instead. The waste and compaction allowances follow common trade practice; see our methodology page for the derivation of each formula and the standards it references.

Worked example. With length = 10 ft, width = 10 ft, depth = 2 in, type = Dry sand (100 lb/ft³), price per ton = 35 $, the calculator returns:
Volume0.62 cu yd
Material needed0.88 tons
Estimated cost$31

One ton covers ~114 sq ft at 2 in deep.

Where this fits in the project

Aggregate quantities feed the layers above them: after excavation, base material is placed in compacted lifts before asphalt or concrete goes down. Convert your tonnage to trips with the truckload calculator before scheduling delivery.

How this connects to your project

No quantity stands alone — each material in the chain depends on the ones around it. These are the planning steps that pair with the sand calculator:

Frequently asked questions

How much sand for paver bedding?

Exactly 1 in of concrete (coarse) sand — one ton beds about 200 sq ft. Never use fine mason sand for bedding.

Wet or dry weight when ordering?

Suppliers sell by wet weight as-delivered; wet sand runs ~120 lb/ft³, so a ‘ton’ of wet sand is less material.

Estimates are for planning. Material densities, coverage rates and prices vary by region and supplier — confirm final quantities before ordering, and check local code where structural or electrical work is involved.
