Frequently Asked Questions
How do I use this calculator?
Enter your project dimensions (length, width, and depth) in the calculator above. The tool will automatically calculate the required materials, costs, and provide detailed estimates for your project. All calculations use industry-standard formulas and current 2026 pricing.
What measurements do I need?
You'll need the length and width of your project area in feet, and the depth or thickness in inches. Measure carefully for accurate results. For irregular shapes, break the area into rectangles and calculate each section separately.
How accurate are these calculations?
Our calculators use industry-standard formulas and densities for high accuracy (±5%). However, always add 10-15% extra material for waste, compaction, and irregular surfaces. Confirm exact specifications with your contractor or supplier.
Should I order extra material?
Yes, always order 10-15% more than calculated. This accounts for compaction (materials compress during installation), waste from trimming and spillage, and irregular base surfaces. It's better to have extra than run short mid-project.
