What size snow blower do I need?
Size on intake height and your worst storm, not on clearing width or average snowfall. Under 9 inches on pavement, a 21-inch single-stage is enough; anything deeper or any plow berm means a two-stage with a 20-inch-plus intake.
The published limits are consistent across two sources. Single-stage: 18-22 inches wide, up to about 13 inches of intake, rated to roughly 9 inches of snow, throwing up to 25 feet. Two-stage: 20-38 inches wide, up to 23 inches of intake, up to about 16 inches of snow, throwing up to 35 feet. Three-stage adds an accelerator and is for repeated 18-inch-plus wet snow.
Clearing width only changes how many passes you make. Intake height changes whether the machine functions when a storm overdelivers, and the plow berm at the end of the drive is denser than anything that fell from the sky.
Within two-stage machines, a manufacturer's own guidance puts 20-inch models on smaller drives seeing up to 12 inches, 24-28 inch models on longer drives with heavy wet snow, and 30-inch-plus models where up to 18 inches is normal. Both sizing sources sell or review these products, so treat the numbers as guidance rather than test results.

How Much to Spend on a Snow BlowerBy Purchasd Research. We used manufacturer and dealer product pages for prices, specifications and warranty terms; manufacturer sizing guidance and an independent buying guide for stage selection; manufacturer service documentation for wear parts; an independent tool review for battery performance; owner forum discussion — one Garage Journal thread and twelve Reddit threads read in full — for real-world preferences and failure points; and a used-value reference for resale. Manufacturer material established identity and specifications. Owner evidence was used to identify decision factors and failure modes, never to estimate defect rates. Prices are manufacturer or retailer prices observed on the dates given, before tax, assembly and delivery. Purchasd received no manufacturer payment, review units or affiliate consideration for this research. Most sizing guidance in this category is published by companies that sell snow blowers, and the used-value reference is an unattributed aggregator; each source is labeled by bias. Purchasd has not run any of these machines in snow.
