Why weight varies
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. 12 tons at about 1.2 tons per yard is 10.0 yards; multiply by 324 and divide by the depth in inches for square feet. At 3 inches that is roughly 1,080 square feet, and at 6 inches about 540.

Getting it home
Have it delivered or use a rated dump trailer at this weight. The topsoil calculator converts area and depth into yards.
Checking quality
Good bulk soil is dark, crumbly and free of trash, large rocks and weed roots. Ask whether it is screened and whether compost is blended in. If possible, look at the pile before ordering or ask for a sample.
Timing the job
Spring and early fall are the easiest times to spread soil and mulch: the ground is workable and plants are ready to root. Avoid spreading right before heavy rain, which can wash fresh material off slopes and into drains.
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.
Common mistakes
Many people underestimate settling, so beds end up low by the second season. Others pile soil or mulch against tree trunks and siding, which invites rot and insects. Wet, sticky soil should wait for a drier day before spreading.
