Why weight varies
Topsoil can weigh from about 1 ton per yard when dry to well over 1.3 tons when wet. If you buy by the ton after rain, you get less volume. Ask the yard for their typical weight per yard.
Converting tons to yards and back
To go from tons to cubic yards, divide by the weight per yard: 15 ÷ 1.2 = 12.5 yards. To go the other way, multiply yards by 1.2. Square feet covered equals cubic yards × 27 × 12 ÷ depth in inches, so at 3 inches 15 tons covers about 1,350 square feet.

Hauling it
15 tons is more than a typical pickup should carry; delivery or a dump trailer is safer. The topsoil calculator converts area and depth into yards.
Checking quality
Squeeze a handful: quality topsoil holds together loosely and breaks apart, rather than forming a sticky ball of clay or falling apart like sand. Avoid soil that smells sour or contains debris.
Weight and hauling
A cubic yard of soil can weigh a ton or more, and mulch roughly a quarter to half of that depending on moisture. Check your vehicle’s payload before hauling, and keep trailer loads within the rated capacity.
Delivery and spreading
Bulk soil and mulch are usually dumped in one pile, so choose a spot on a tarp or driveway close to the work. A wheelbarrow holds about 1/10 to 1/6 of a yard, so a few yards means many trips; a helper and two wheelbarrows speed things up.
Common mistakes
Buying by the bag for a large area is the classic error: dozens of bags cost far more than a bulk yard. Another is skipping compost or using unscreened soil full of clods and roots. Spreading soil when it is soaking wet compacts it and makes it hard for roots and water to move.
