Quick start
- Enter length and width in feet.
- Enter sand depth in inches. For a paver bedding layer, that might be around 1 inch. For a sandbox, it might be much deeper.
- Enter tons per cubic yard from your supplier when you have it, then add waste if needed.
Best uses
Use this guide when you need a quick material estimate for a rectangular layer before checking the bag label, supplier density, delivery minimum, or project instructions.
- Estimate sand for paver bedding or leveling.
- Estimate sand volume for a sandbox or small base layer.
- Convert cubic yards into estimated tons.
- Compare different depth assumptions.
What this calculator is solving
The Sand Calculator estimates volume and tonnage for a rectangular sand layer. It is useful for paver bedding, leveling layers, sandboxes, pool-base checks, aquarium-bed rough math, and small base projects.
Match each input label on the calculator to the sand bed length, width, depth, tons per cubic yard, and waste percent.
The formula in plain language
In plain language: Cubic feet = length x width x depth inches / 12. Adjusted cubic feet = cubic feet x (1 + waste percent / 100). Cubic yards = adjusted cubic feet / 27. Estimated tons = cubic yards x tons per cubic yard. The examples on the page are there so you can compare your inputs with a worked example before copying the answer.
The calculator turns depth inches into feet, finds cubic feet, adds waste, converts to cubic yards, then multiplies by tons per cubic yard.
How to read the answer
Read cubic yards as the bulk volume number. Read estimated tons as the supplier conversation starter, because dry sand, wet sand, play sand, concrete sand, and compacted sand can weigh differently.
- A 10 ft by 10 ft area at 1 inch deep is 8.33 cubic feet before waste.
- With 10% waste, that becomes 9.17 cubic feet, or about 0.34 cubic yards.
- At 1.35 tons per cubic yard, the estimate is about 0.46 tons.
- Density used reminds you how weight was estimated.
Common mistakes to avoid
The big mistake is treating every sand type like it has one fixed weight. Inch Calculator lists dry sand around 1.3 to 1.5 tons per cubic yard and wet sand around 1.5 to 1.7 tons, so supplier density matters.
- Do not assume dry and wet sand weigh the same.
- Do not forget compaction and leveling loss.
- Do not use this page as a full paver plan. Base gravel, bedding sand, joint sand, edge restraints, slope, drainage, and compaction are separate checks.
- Do not use pool or aquarium search intent as water-volume advice. This page estimates sand material, not water gallons.
- Ask the supplier for material-specific density and delivery minimums.
How To Read A Small Paver-Sand Example
Say the bedding area is 10 feet by 10 feet and the sand layer is 1 inch deep. The raw volume is 8.33 cubic feet.
Add 10% waste for leveling and spreading loss. That gives about 9.17 cubic feet, or 0.34 cubic yards. At 1.35 tons per cubic yard, the rough weight is about 0.46 tons.
If you buy 50 lb bags, convert 0.46 tons to about 920 lb, then divide by 50. That is about 19 bags before you check the bag label.
Bags, Tons, And Supplier Density
The calculator does not output bag count because bags vary by weight and volume. Use the result as a bridge: tons help with bulk orders, cubic feet help with bag-volume labels, and pounds help with bag-weight labels.
If a supplier gives you a sand density, use that value. If not, keep the result as a planning estimate and expect moisture, compaction, and sand type to move the real order.
Pool, Aquarium, And Round-Area Limits
For pool sand, this page can estimate a rectangular sand base or help check a supplier density. It does not estimate pool water volume.
For aquarium sand, convert tank length and width to feet and use the desired sand depth in inches. Then check the product label because aquarium sand is usually bought by bag.
For a round area, calculate the circle area first or split the project into simpler pieces. The live Sand Calculator itself expects a rectangular length and width.

FAQ in plain language
When should I use the Sand Calculator?
Use it when your task matches one of these common needs: Estimate sand for paver bedding or leveling. Estimate sand volume for a sandbox or small base layer. It works best when you already know the measurements, amounts, units, or options the page asks for.
What is the Sand Calculator doing with my inputs?
In plain language: Cubic feet = length x width x depth inches / 12. Adjusted cubic feet = cubic feet x (1 + waste percent / 100). Cubic yards = adjusted cubic feet / 27. Estimated tons = cubic yards x tons per cubic yard. The examples on the page are there so you can compare your inputs with a worked example before copying the answer.
What do the main Sand Calculator inputs mean?
Length and width: the rectangular project size in feet. Depth: the average sand depth in inches. Tons per cubic yard: the supplier density used to turn volume into weight. Waste percent: extra sand for leveling, spreading loss, compaction, and uneven areas.
How should I read the Sand Calculator answer?
Read the headline estimate first, then check the material, waste, coverage, and unit lines. For project tools, the supporting lines are often the difference between a rough idea and a list you can actually shop from.
What should I double-check before trusting the answer?
Sand density changes with moisture, sand type, compaction, and supplier measurement. This is a rectangular material estimate, not a paver, pool, aquarium, or drainage specification. Also check the unit, scale, mode, and result limit because small input changes can change the answer.
What does the Sand Calculator estimate?
It estimates a rectangular layer of sand in cubic feet, cubic yards, and tons. Enter length, width, depth, density, and waste percent.
Can I use this for paver sand?
Yes for the bedding or leveling sand layer if the area is rectangular. Keep base gravel, edge restraints, slope, compaction, and joint sand as separate checks.
