Asphalt Coverage per Ton
A ton of hot mix does not cover a fixed area. It covers an area that depends on how thick you spread it. This page converts between tons and covered area in both directions.

Assumes the material is placed and compacted to the depth you enter. Loose depth before rolling is roughly 20–25% greater than finished depth.
How many square feet will a ton of asphalt cover?
At the standard 145 lb/ft³ for dense-graded hot mix, one ton occupies 13.8 cubic feet. Spread that over 2 inches and you get 82.8 square feet, which is a little over a 9 × 9 ft square. At 1 inch the same ton reaches 165.5 sq ft; at 4 inches it reaches only 41.4 sq ft.
In square yards, one ton at 2 inches is 9.2 sq yd. That single number explains most driveway quotes: a 20 × 20 ft pad (44.4 sq yd) at 2 inches needs just under 5 tons.
| Depth | Square feet | Square yards | Cubic feet used |
|---|---|---|---|
| 1 inch | 165.5 | 18.4 | 13.8 |
| 1.5 inches | 110.3 | 12.3 | 13.8 |
| 2 inches | 82.8 | 9.2 | 13.8 |
| 2.5 inches | 66.2 | 7.4 | 13.8 |
| 3 inches | 55.2 | 6.1 | 13.8 |
| 4 inches | 41.4 | 4.6 | 13.8 |
The cubic feet column never changes, and that is the point. A ton is a ton. Depth decides how thin you can spread those 13.8 cubic feet, and nothing else on this page affects that except density.
Coverage by tonnage and depth
Most jobs are more than one ton, so here is the same relationship for realistic order sizes.
| Weight | 1 inch | 2 inches | 3 inches | 4 inches |
|---|---|---|---|---|
| 1 ton | 165.5 | 82.8 | 55.2 | 41.4 |
| 2 tons | 331.0 | 165.5 | 110.3 | 82.8 |
| 5 tons | 827.6 | 413.8 | 275.9 | 206.9 |
| 10 tons | 1,655 | 827.6 | 551.7 | 413.8 |
| 20 tons | 3,310 | 1,655 | 1,103 | 827.6 |
| 25 tons | 4,138 | 2,069 | 1,379 | 1,034 |
How many tons do I need per square yard?
This is the direction that matters when you have measured the driveway and need to place an order. Square yards are converted to square feet first (multiply by 9), then to volume using the depth, then to weight using the density.
tons = sq yd × 9 × (depth in inches ÷ 12) × density ÷ 2,000At 145 lb/ft³ this reduces to
tons = sq yd × depth × 0.0544
Example: 300 square yards at 2 inches. 300 × 9 = 2,700 sq ft. 2,700 × 0.1667 = 450 cubic feet. 450 × 145 ÷ 2,000 = 32.6 tons. The shortcut gives 300 × 2 × 0.0544 = 32.6 tons, which is the same answer without the intermediate steps.
| Square yards | 1 inch | 2 inches | 3 inches | 4 inches |
|---|---|---|---|---|
| 25 | 1.36 | 2.72 | 4.08 | 5.44 |
| 50 | 2.72 | 5.44 | 8.16 | 10.88 |
| 100 | 5.44 | 10.88 | 16.31 | 21.75 |
| 200 | 10.88 | 21.75 | 32.63 | 43.50 |
| 500 | 27.19 | 54.38 | 81.56 | 108.75 |
| 1,000 | 54.38 | 108.75 | 163.13 | 217.50 |
Coverage by mix type
Lighter mixes cover more area per ton because a ton of them takes up more space. Cold patch at 120 lb/ft³ is the lightest common material; stone mastic at 152 is the heaviest.
| Mix | Density (lb/ft³) | Sq ft per ton at 2 in | Sq yd per ton at 2 in |
|---|---|---|---|
| Hot mix (HMA) | 145 | 82.8 | 9.2 |
| Warm mix (WMA) | 142 | 84.5 | 9.4 |
| Stone mastic (SMA) | 152 | 78.9 | 8.8 |
| Recycled millings | 130 | 92.3 | 10.3 |
| Cold patch | 120 | 100.0 | 11.1 |
Why quoted coverage numbers differ from this table
Three things move the real number away from any table, and all three are worth knowing before you order.
- Compaction. Published densities are for finished, rolled material. If your crew spreads 2 inches loose and rolls it to 1.6 inches, one ton covers 100 sq ft instead of 83, and the finished surface will be thin enough to crack within a season. Order for finished depth, not loose depth.
- Waste and spillage. Add 5% on small jobs. Trucks leave material stuck in the bed, and transitions, edges and hand-work always consume more per square foot than the open middle of a driveway.
- Actual mix design. Dense-graded surface mix from one plant can run 143 and from another 150. That is a 5% swing either way, which on a 20-ton order is a ton of material.
So the honest version of the answer: 83 sq ft per ton at 2 inches is the number to estimate with, and the number to order from is that figure minus about 5%.
Using coverage as a quote check
Coverage is the fastest way to catch a bad quote. Take the tonnage in a quote, multiply by the coverage figure for the stated depth, and see whether the result matches the area of your driveway. If a contractor quotes 8 tons for a 2,000 sq ft driveway at 2 inches, the math says that covers 662 sq ft — the driveway would end up a third as thick as promised, or the quote is missing material.
The check works the other way too. A quote that specifies 25 tons for 1,200 sq ft at 2 inches is about 30% more material than the job needs, and the extra is either a mistake or a line item you should ask about.
Frequently asked questions
How many square feet will a ton of asphalt cover?
About 83 sq ft at 2 inches deep with dense-graded hot mix. At 1 inch a ton covers 165 sq ft, and at 4 inches only 41 sq ft. Coverage per ton is inversely proportional to depth.
How many square yards does a ton of asphalt cover?
9.2 sq yd at 2 inches, 18.4 sq yd at 1 inch, and 6.1 sq yd at 3 inches. Divide square feet by 9 to convert.
How do I convert tons of asphalt to square yards?
Divide tons by the density factor and depth. For hot mix at 145 lb/ft³: sq yd = tons ÷ (depth in inches × 0.0544). Five tons at 2 inches gives 5 ÷ 0.1088 = 46 sq yd.
How many tons of asphalt do I need per square yard?
At 2 inches, 0.109 tons per square yard, or about 9.2 sq yd per ton. At 3 inches it is 0.163 tons per square yard.
Does a thicker layer cover less area per ton?
Yes, and proportionally. Doubling depth halves coverage. Two inches covers 83 sq ft per ton and 4 inches covers 41 sq ft per ton with the same material.
How much area does a 50 lb bag of asphalt cover?
At 2 inches, roughly 1.9 sq ft per 50 lb bag of hot mix, and about 2.3 sq ft for cold patch. Bags are for potholes, not for areas you would measure in square yards.
Should I order extra asphalt for waste?
Add 5% for a straightforward rectangular driveway and 10% where there are curves, tight access or a lot of hand-work at the edges. Ordering 5% short means a second delivery charge that usually exceeds the cost of the extra material.
