A starting point, not gospel — your county extension office knows the specific cultivars that win in your exact area. Shade changes everything; the shade picker goes deeper on that.

How the match works
climate rules out the impossible → priority picks among what's left
Grass selection is elimination, not optimization: your winters and summers delete the species that can't survive them, and only then do preferences matter. Fighting your climate — bermuda in Minnesota, bluegrass in Georgia — is the root of most lawn misery, and no amount of care overcomes it.
The transition-zone truth
If you're in the middle band, accept that nothing is perfect and pick your compromise: tall fescue (cool-season, heat-toughened) is the safe default, while zoysia is the warm-season play if you'll trade a browner winter for a bulletproof summer. Trying to grow a picture-perfect cool-season carpet through a transition-zone July is the region's classic heartbreak.
Once you've chosen
The seed calculator knows the rate for your pick, the feeding schedule and mowing height both change by grass type, and if shade is any part of the picture the shade picker handles that zone specifically. Match the grass to the yard, then let the rest of the site tune the care.
Frequently asked questions
How do I choose the right grass type for my lawn?
Climate narrows it first (cool-season grasses north, warm-season south, a transition-zone overlap in the middle), then your priorities pick the winner: drought tolerance, shade, foot traffic, and how much work you want. There's no single 'best grass' — only the best match for your yard and effort, which is what this tool sorts to.
What is the transition zone?
The band across the middle of the country (roughly Kansas to Virginia) where summers cook cool-season grass and winters kill warm-season grass — so neither is fully happy. Tall fescue is the usual transition-zone answer: cool-season, but deep-rooted enough to tough out the heat.
What's the most low-maintenance grass?
Warm-season: zoysia and centipede (centipede is nicknamed 'lazy man's grass' for a reason — it wants little feeding). Cool-season: fine fescue and tall fescue ask the least water and mowing. The high-maintenance crowd is bermuda (fast grower, frequent mowing) and Kentucky bluegrass (thirsty).
Which grass handles the most foot traffic?
Warm-season bermuda and zoysia take heavy play and repair themselves; cool-season tall fescue and perennial rye are the toughest northern options. Kentucky bluegrass recovers well too (it spreads to fill damage). Fine fescue is the weakling here — beautiful in shade, poor under cleats.
