How much sand do I need for 800 square feet?

Answer

800 square feet covered 1 inch deep takes
2.47 cubic yards

That is 66.67 cubic feet, and it weighs roughly 6,916–8,398 lbs (3.46–4.2 tons) when dry.

At 1 inch deep one cubic yard of sand covers 324 square feet, so 800 square feet takes 2.47 cubic yards. The same patch under topsoil comes out quite differently — topsoil is lighter and normally goes down several times thicker.

How the Volume Is Calculated

Cubic yards = ft² × inches ÷ 324

The 324 is not a fudge factor. A cubic yard is 27 cubic feet, and a foot is 12 inches, so a cubic yard spread one inch deep covers 27 × 12 = 324 square feet.

800 square feet × 1 inch ÷ 324

=

2.47 cubic yards

(66.67 cubic feet)

The depth is our assumption, not a recommendation. 1 inch is about what a bedding course under pavers comes to, but we have no published source for it — a play area or a base layer is far deeper. Type your own depth into the form above, or read it off the table below.

Depth scales the answer in a straight line, so the whole range fits in one table. Type any depth into the form above to work it out in full. The last column is the coverage of a single unit of volume, which is the number to keep in mind when a supplier quotes by the cubic yard.

What It Weighs and What to Order

Volume is the exact half of this page; weight is the approximate half. Only the top of the band has a source: the WSDOT Design Manual puts material that is essentially all sand at 3,400 lbs per cubic yard compacted. Loose sand, which is how it arrives on a truck, is lighter — and WSDOT publishes no truck-measure figure for sand, so 2,800 lbs is our own allowance rather than a quoted number.

Volume 2.47 cubic yards
In cubic feet66.67 cubic feet
Weight, dry 6,916–8,398 lbs
In tons 3.46–4.2 tons
Order with 10% for waste 2.72 cubic yards

The 10% is quoted, not invented: the WSDOT Design Manual tells estimators to increase required quantities by 10% to allow for waste when material is stockpiled. A screeded sand bed also loses depth once it is compacted. Bagged sand is usually sold by weight, so divide the 6,916–8,398 lbs by the weight printed on the bag — and remember that band is wide, so it gives you a range of bag counts, not one number.

Every weight here is dry weight. WSDOT states it plainly: weights shown are dry weights and corrections are required for water contents. Damp sand off a yard can be noticeably heavier.

About "Sand Calculator" Calculator

This calculator works out how much sand an area needs: the volume in cubic yards and cubic feet, what it weighs in pounds and tons, and how much one cubic yard covers. For example, it can help you find out how much sand do I need for 800 square feet? (The answer is: 2.47 cubic yards). Enter the area (e.g. 800 square feet), choose the unit; the answer assumes a layer 1 inch deep and the depth table covers the rest.

FAQ

How much sand do I need for 800 square feet?

800 square feet covered 1 inch deep takes 2.47 cubic yardsThat is 66.67 cubic feet, and it weighs roughly 6,916–8,398 lbs (3.46–4.2 tons) when dry.

How many cubic yards of sand is 800 square feet?

2.47 cubic yards, at 1 inch deep. The arithmetic is exact: 800 × 1 ÷ 324 = 2.47. One cubic yard spread an inch deep covers 324 square feet, which is where the 324 comes from.

How much does 800 square feet of sand weigh?

Roughly 6,916–8,398 lbs, or 3.46–4.2 tons, dry. The top of that band comes from the WSDOT Design Manual, which puts essentially-all-sand material at 3,400 lbs per cubic yard compacted; the bottom is our own allowance for loose sand as delivered, since no truck-measure weight is published for sand. Wet sand is heavier again.

How much sand for 800 square feet at 4 inches?

9.88 cubic yards. Depth scales the answer straight up and down: at 4 inches one cubic yard covers 81 square feet, against 324 square feet at 1 inch.

How much sand should I order for 800 square feet?

2.72 cubic yards — the calculated 2.47 cubic yards plus 10%, rounded up. The WSDOT Design Manual tells estimators to increase required quantities by 10% to allow for waste when material is stockpiled, and a sand bed loses depth once it is screeded and compacted.
