Accurately calculate how much paver sand you need for patios, driveways, or walkways with our free Paver Sand Calculator. Fast, easy, and reliable.
Planning a paver project like a patio, driveway, or walkway? One of the most crucial materials you’ll need is paver sand. It forms the foundation that keeps your pavers level and secure. However, figuring out how much sand you need can be confusing. That’s where our Paver Sand Calculator comes in.
We developed this easy-to-use tool to help homeowners and professionals accurately calculate the right amount of bedding sand and polymeric joint sand for any paver installation. Whether you're shopping from Home Depot, Lowe's, or a local supplier, this calculator ensures you don’t waste money or run short.
Paver sand is used as a bedding layer beneath the pavers to create a smooth, stable surface. You may also need polymeric sand to fill the joints between pavers, which locks them in place and prevents weed growth.
Understanding the amount of sand you need involves simple math, and our calculator does the work for you. But if you’re curious, here’s how the formula works.
Bedding Sand Formula (Under Pavers):
To calculate the volume of sand required under your pavers:
Total Sand Volume = Length × Width × Depth
Example:
If your patio is 10 feet long and 12 feet wide, and you want 1 inch (0.0833 feet) of bedding sand:
10 ft × 12 ft × 0.0833 ft = 10 cubic feet of sand
If you're using polymeric sand for joints, calculate it separately:
Joint Sand Volume = Joint Length × Joint Width × Joint Depth
Make sure all values are in feet for accurate results.
You can also estimate coverage based on bag information. A 50 lb bag of polymeric sand typically covers:
Using our online calculator is very simple:
Step 1:
Enter the length and width of your area in feet, meters, inches, or any unit.
Step 2:
Choose your desired bedding depth (usually 1 inch).
Step 3:
Optionally, add joint dimensions if you're using polymeric sand.
Step 4:
Select your sand density (100 lb/ft³ is standard for dry sand), and add a waste factor (usually 10–15%) to ensure you have enough.
Step 5:

Yes, you can use up to 2 inches of sand as a bedding layer. However, the most recommended thickness is 1 inch. Too much sand can lead to shifting over time unless properly compacted. If you do choose 2 inches, make sure to adjust your calculations accordingly in the calculator.
Whether you're building a small walkway or a large patio, estimating materials correctly is essential for a strong and lasting installation. Our Paver Sand Calculator is designed to help you save time, reduce waste, and stay within budget.
From homeowners looking for DIY patio solutions to contractors preparing driveway paver installations, this tool is your reliable companion.
No more guesswork. Just input your measurements, and let the calculator do the math. Try it today and get your project started the right way!
Multiply the length and width of your area to get square footage. Then multiply by the desired depth (in feet). For example, 10 ft × 10 ft × 0.0833 ft (1 inch) = 8.33 ft³.
Typically, a 50 lb bag covers 50–75 sq ft for narrow joints and 30–40 sq ft for wider joints.
The ideal bedding sand depth is 1 inch (about 0.0833 feet). You can go up to 2 inches if properly compacted.
Yes, the calculator works for driveways, patios, walkways, and any paver surface.
Yes! This tool offers more flexibility with units, joint sand calculations, and waste factor customization.
