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.
Assumptions to Check
Before ordering materials, confirm the dimensions, product coverage, waste factor, and local installation requirements for your project. Manufacturer coverage tables and local code rules can change the final quantity, especially for structural work, exterior projects, and irregular layouts.
