How to Use This Calculator
- Enter the total area of your project in square feet (length × width).
- Enter the desired depth of decomposed granite in inches (typically 2-4 inches for pathways).
- The coverage per bag is pre-filled (15 sq ft per bag for decomposed granite), but you can adjust this if needed.
- Click the "Calculate" button to determine the number of bags needed.
- If you know the cost per bag, enter it to calculate the total project cost.
Formula Explanation
The calculator uses the following formula:
Total Bags = (Area × Depth × 12) / Coverage
Where:
- Area = Project area in square feet
- Depth = Material depth in inches
- Coverage = Coverage per bag in square feet
- 12 = Number of inches in a foot
Things to Consider
- This calculator provides an estimate. It's recommended to purchase 10-15% extra material for waste.
- For uneven surfaces, you may need to adjust the depth accordingly.
- Consider factors like compaction rate when planning your project.
- For larger projects, check with suppliers for bulk pricing options.
