The sod calculator assumes the decision's already made — sod, not seed. Before running the numbers, it's worth a quick gut check on whether sod is actually the right call for your yard, since the two options trade off very differently.
Sod Wins on Speed
Sod gives you a usable, walkable lawn in roughly 2-3 weeks. Seed takes one to two full growing seasons to fully establish and fill in. If you need the yard functional soon — a new home, an event, a slope actively eroding — sod is the clear choice regardless of the cost difference.
Seed Wins on Cost and Variety
Seed typically costs a fraction of sod per square foot for the same area, and the selection is far wider — you can pick a grass type genuinely suited to your specific shade, sun, and foot-traffic conditions rather than whatever variety the sod farm happened to grow. If budget matters more than timeline, seed is usually the better trade.
Sod Still Needs Real Prep
The most common sod mistake is treating it like instant grass — rolling it out over hard, unprepared dirt and expecting it to just take. It still needs graded, loosened soil underneath, and the first two to three weeks require careful, consistent watering while the roots actually establish into the ground below. Skip either step and even good sod can die in patches.
Once you've settled on sod, run your own numbers with the sod calculator to get your pallet count.
