What size snow blower do I need for my driveway?

Reviewers generally suggest a 24-inch two-stage for typical suburban driveways, a 26-to-28-inch model for larger drives or frequent heavy snowfall, and a 30-to-32-inch track-drive machine for long driveways, steep grades, or regions with frequent deep snow. Wider isn't always better, owners note the wider, heavier units are harder to maneuver in tight spaces.
