How many bags of sand for pavers?
Quick Answer
A 10×10 paver patio (100 sq ft) needs approximately 14 bags of 50-lb coarse bedding sand for the 1-inch setting layer, plus 3–4 bags of polymeric sand for joint filling. For larger areas, plan on 0.5 cubic feet of bedding sand per square foot (at 1-inch depth).
Quick Reference Table
| Patio size (1" bedding layer) | Sand bags for paver projects |
|---|---|
| 10×10 ft (100 sq ft) | 14 bags bedding + 4 bags jointing |
| 12×12 ft (144 sq ft) | 20 bags bedding + 5 bags jointing |
| 10×20 ft (200 sq ft) | 28 bags bedding + 7 bags jointing |
| 20×20 ft (400 sq ft) | 55 bags bedding + 14 bags jointing |
How to Calculate It Yourself
- 1
Calculate bedding sand volume: area × 1" depth = area × 0.083 ft = cubic feet.
- 2
For 100 sq ft: 100 × 0.083 = 8.3 cubic feet of sand.
- 3
One 50-lb bag of coarse sand = ~0.5 cubic feet → 8.3 ÷ 0.5 = 16.6 → 17 bags.
- 4
Jointing sand: estimate 1 bag per 25 sq ft of paver surface (joint width varies).
- 5
100 sq ft ÷ 25 = 4 bags of polymeric jointing sand.
Pro Tip
Use coarse concrete sand (not play sand or stone dust) for the bedding layer — it compacts firmly and drains well. Never use polymeric sand as bedding — it's only for filling joints after pavers are laid.
