Which depth?
Use 4 to 6 inches for a new lawn on poor soil, 2 inches for leveling, and a thin skim when top dressing. More is not always better: piling soil around trees can harm their roots.
Buying it
Order bulk; bags at this volume cost far more and mean a lot of lifting. Ask whether the soil is screened, which removes rocks and roots. See how much a yard of topsoil covers.

Measuring accurately
Measure each bed or area in feet and multiply length by width for square feet. For curved beds, a rough rectangle around the shape overestimates; split it into smaller shapes instead. Measure the depth you actually want to add, not the total depth of the bed if some soil is already there.
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.
