How Asphalt Calculator Square Feet Works
Visual calculation flow
L × W or Area sq ft
→ × Thickness in ÷ 12 = ft
→ Volume cu ft
→ × Density 145 lb/ft³
→ Weight tons
Tons = Area (sq ft) × Thickness (in) ÷ 12 × Density ÷ 2000 Step 1: Input your area by either entering Length × Width in feet, or entering total square footage directly.
Step 2: Select thickness in inches. The calculator converts to feet (divides by 12) for volume calculation.
Step 3: Volume (cu ft) is multiplied by density (default 145 lb/ft³) to get total weight in pounds.
Step 4: Weight is divided by 2000 to convert to US tons. A 10% overage recommendation is included.
Square Feet Asphalt Calculator FAQs
How many square feet does one ton of asphalt cover?
Coverage depends on thickness. At 1 inch thick, one ton covers approximately 160-165 sq ft. At 2 inches thick, about 80 sq ft. At 3 inches, around 53 sq ft. This assumes standard HMA density of 145 lb/ft³. Actual coverage varies slightly by mix design.
Why use square feet instead of square yards?
Square feet is more intuitive for most homeowners when measuring driveways and smaller areas. It's also the unit used for property listings and home improvement estimates. However, contractors often quote in square yards (1 sq yd = 9 sq ft) for larger commercial projects. Our calculator shows both units.
How do I measure my driveway in square feet?
Use a tape measure to find length × width in feet. For irregular shapes, divide into rectangles, calculate each section's area, then add them together. For curved areas, use average width. For circles, use π × radius². Our calculator accepts individual dimensions or direct square footage input.
Should I add extra material for waste?
Yes! We recommend adding 5-10% extra material. This accounts for variations in thickness, compaction, and minor waste. For irregular edges or narrow areas, add 10-15%. Running short mid-job is much more costly than ordering slightly extra - leftover hot mix asphalt cannot be returned.
