Wet vs dry soil
Moisture is the big variable. Dry, screened topsoil is lighter; wet clay-heavy soil is much heavier. Buying by the yard avoids paying for water weight.
Converting tons to yards and back
The conversion runs through cubic yards. 20 tons at about 1.2 tons per yard is 16.7 yards; multiply by 324 and divide by the depth in inches for square feet. At 3 inches that is roughly 1,800 square feet, and at 6 inches about 900.

Getting it home
Have it delivered or use a rated dump trailer at this weight. The topsoil calculator converts area and depth into yards.
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.
Measuring accurately
Walk the area with a tape and sketch it. Break odd shapes into rectangles and circles. If you are topping up an existing bed or lawn, measure only the new depth, since adding a full depth on top of existing soil overbuys.
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.
Timing the job
Plan deliveries for a dry stretch so the pile and the ground are workable. Early spring mulching suppresses weeds before they sprout, while fall soil work gives beds time to settle before planting.
