What size cutting deck is best for a corded mower?

Verified-purchase reviewers and lawn-care forum consensus point to 15–16 inch decks for tight, obstacle-heavy yards where maneuvering around the cord is the main challenge, and 19–20 inch decks for more open lawns where fewer passes save time. Wider decks are heavier and harder to turn, which matters more on a corded mower because you're already managing an extension cord.
