If you’re planning to install a new patio in your yard, one of the first and most important questions you’ll face is: how much sand do I need for the base? This might seem like a small detail, but trust us—it’s one of those things that can make or break the entire project.
At Kirk Allen Landscape Supply in New Jersey, we get this question all the time from homeowners, contractors, and DIYers alike. So, we’ve put together a detailed guide to help you figure out exactly how much sand you need, what type of sand to use, and how to make sure your patio is built on a solid, long-lasting foundation.
Why Do You Need Sand for a Patio Base?
Before we dive into numbers, let’s take a quick look at why sand is essential in the first place. Sand acts as a leveling layer between your compacted gravel (or crushed stone) base and your pavers. It allows for slight adjustments as you lay the pavers and helps keep them in place.
Sand also improves drainage, prevents shifting over time, and protects your patio from developing dips and uneven surfaces. Without the proper amount—or the right type—you could be setting yourself up for major maintenance headaches down the road.
The Ideal Patio Base Layer Structure
A sturdy patio base typically consists of three layers:
- Excavated ground
- Gravel or crushed stone base (4″–6″)
- Sand layer (1″–2″)
- Pavers or stones
Today, we’re focusing specifically on the sand layer, which is the topmost base layer right underneath the pavers.
How Much Sand Do You Need?
The amount of sand you’ll need depends mainly on two things:
- The size of your patio
- The thickness (depth) of the sand layer
🔢 Basic Calculation Formula:
To calculate how much sand you need, use this simple formula:
Cubic feet = Patio Area (in square feet) × Depth (in feet)
Then convert cubic feet to cubic yards (since sand is usually sold by the yard):
Cubic yards = Cubic feet ÷ 27
✅ Example:
Let’s say your patio is 12 feet by 14 feet and you want a 2-inch thick sand base:
- Area = 12 × 14 = 168 sq. ft.
- Depth = 2 inches = 0.167 feet
Now multiply:
- Volume = 168 × 0.167 = 28.06 cubic feet
- Convert to cubic yards: 28.06 ÷ 27 = ~1.04 cubic yards
So, for a 12×14 patio with a 2″ sand base, you’ll need just over 1 cubic yard of sand.
Pro Tip: Always Round Up
It’s better to have a little extra sand than not enough. Uneven ground, settling, and compaction can all affect your total volume. Round up your final number and order an extra 5–10% buffer.
What Type of Sand Should You Use?
All sand is not created equal. The best type of sand for patio bases is concrete sand or coarse, washed sand. These are also referred to as:
- Bedding sand
- Paver base sand
- Sharp sand
Avoid using fine sand (like play sand), as it doesn’t compact well and can lead to shifting or uneven surfaces over time.
At Kirk Allen Landscape Supply, we carry high-quality bedding sand that’s perfect for paver patios, walkways, and more. It compacts beautifully and provides excellent drainage and stability.

FAQs: Sand for Patio Bases
❓ Can I use all sand and skip the gravel?
No. Sand alone does not provide a solid enough base. A compacted gravel or crushed stone layer is essential for stability and drainage.
❓ How deep should the sand layer be?
Typically, a 1″ to 2″ thick sand layer is ideal. Any deeper and you risk shifting and sinking over time.
❓ Should I compact the sand before laying pavers?
Yes, lightly compact the sand layer and screed it level before setting the pavers. You want a smooth, even surface to work on.
Tips for a Successful Patio Installation
Here are a few extra pointers that can save you time, money, and headaches:
- Use edging restraints to prevent paver movement.
- Compact each layer—gravel and sand—for a firm base.
- Check slope and grade to ensure proper drainage away from your home.
- Use a screed board to level the sand evenly before placing pavers.
- Don’t rush the process—precision pays off in the long run.
