How much sand for a 10×10 patio?
Quick Answer
A 10×10 foot patio needs approximately 0.31 cubic yards of coarse bedding sand for the 1-inch setting layer (the standard depth under pavers). That's 8.3 cubic feet — about nine 50-pound bags of coarse sand. For a larger 4–6 inch compacted gravel base, you'll need an additional 1.2–1.9 cubic yards of gravel.
Quick Reference Table
| Patio size | Bedding sand (1" layer) |
|---|---|
| 10×10 ft | 0.31 yd³ / 9 bags (50 lb) |
| 10×20 ft | 0.62 yd³ / 17 bags |
| 12×20 ft | 0.74 yd³ / 20 bags |
| 16×20 ft | 0.99 yd³ / 27 bags |
| 20×20 ft | 1.23 yd³ / 33 bags |
How to Calculate It Yourself
- 1
Bedding sand volume: 10 × 10 × (1/12) = 8.33 cubic feet ÷ 27 = 0.31 cubic yards.
- 2
A 50-lb bag of sand = ~0.5 cubic feet. So 8.33 ÷ 0.5 = 16.7 bags. But actual bag coverage varies — buy 9–10 bags for a 10×10 (bags are heavier than expected).
- 3
Also calculate gravel base: 10 × 10 × (4/12) = 33.3 cu ft ÷ 27 = 1.23 yd³ for a 4-inch base.
- 4
Total materials: 9 bags bedding sand + 1.2–1.9 yd³ compacted gravel base.
Pro Tip
Use coarse concrete sand (not play sand or mason sand) for paver bedding. Fine sand migrates under load. Polymeric sand swept into joints after installation locks pavers in place and resists weeds — budget 1–2 bags of poly-sand for a 10×10 patio.
