What size snow blower do I need for my driveway?

Four things decide the size: how deep your snow gets, how big the driveway is, whether it is paved or gravel, and how steep it is. Snow depth matters most. Driveway size then sets how wide a machine you want. Manufacturers describe driveway size in cars, not square feet, so we do the same here.

Already know the basic difference between stages? Our guide on how to shovel snow safely covers the single- vs. two-stage basics. This page goes further into sizing.

How much snow can each type of snow blower handle?

Ratings vary by brand, so here is what each maker says.

Treat these as limits for a typical storm, not the deepest drift. Ariens says a smaller two-stage can keep pace with a larger one in snow up to about 8-10 inches. Above that, the larger auger and impeller hold their speed better. So if your storms usually stay under 8 inches, a mid-size machine may be all you need.

What clearing width should a snow blower have?

Clearing width is how wide a path you cut in one pass. Common sizes run from 18 inches (corded electric) to 21 inches (single-stage) to 24-30 inches (two- and three-stage). Ariens says a wider housing cuts the number of passes on a wide or long drive.

Wider is not always better. Ariens notes that the same engine works better pushing a narrower housing. Its example: a 301 cc engine clearing 28 inches beats the same engine clearing 30 inches. Cub Cadet also advises matching engine size to your snowfall and driveway rather than oversizing for an average drive.

Honda puts it in cars. Its 24-inch two-stage series suits 1-2 car driveways and sidewalks. For larger areas with frequent heavy snow, Honda points to its larger HSS928 and HSS1332 series.

Throw distance matters on wide drives too. Cub Cadet lists single-stage throws up to 30 feet and two- and three-stage throws up to 40 feet. A short throw on a wide drive means throwing snow onto ground you still have to clear.

What is intake height, and why does it matter?

Intake height is how tall an opening the housing has. By our reasoning, snow taller than the opening has to be cut down in layers. Here are some published figures:

The pattern is clear. Single-stage and electric units top out around 12-13 inches. Two- and three-stage units roughly double that. If a city plow leaves a pile at the end of your drive, give intake height extra weight. That is our own reasoning, not a maker’s rule.

Does a gravel driveway or a slope change the size?

Gravel. Toro says single-stage blowers should not be used on unpaved surfaces. Two- and three-stage units let you raise the housing. Cub Cadet says the adjustable housing lifts the scraper bar above gravel and stone, and recommends skid shoes with a shave plate for gravel or stamped concrete. Some battery single-stage models sell adjustable skid shoes for gravel. EGO markets them that way for its 21-inch model, but follow your owner’s manual.

Slopes. Toro rates its single-stage and crossover blowers for flat or moderately sloped drives, and two-stage for steep slopes. Honda says track drive makes moving up and down inclines easier and clears packed snow better. It suggests a wheel model for flat ground where traction is not an issue. Cub Cadet also recommends tracks for uneven surfaces and inclines.

Electric, battery or gas: which should you get?

Battery makers state coverage per charge. For example, EGO says its 21-inch single-stage clears up to a 14-car driveway with 8 inches of snow on one charge, using two 6.0 Ah batteries. Treat such claims as best case and compare them with your own drive and typical snow. Toro’s lineup chart lists battery single-stage models for drives up to 18 cars.

Gas machines need fuel on hand. See how to store gasoline safely. Honda notes its electric-start models also keep a recoil pull start as backup. Ariens suggests electric start for very cold climates.

What happens if you buy the wrong size snow blower?

• Too small for your snow: single-stage and electric units have intakes around 12-13 inches. By our reasoning, deeper snow means clearing in layers or going back to the shovel. Toro steers storms of 12 inches or more to two-stage machines.
• Wrong type for gravel: Toro says a single-stage should not be used on unpaved surfaces.
• Too narrow for a long drive: Ariens and Cub Cadet both note that a narrow housing means more passes.
• Too wide for the engine: Ariens says a weaker engine pushing a wider housing is less effective, and some two-stage units need a lower gear in heavy snow.
• Too big for a small drive: Cub Cadet warns against oversizing the engine for an average driveway. Honda lists dry weights of 209-243 lbs for its 24-inch series, against 84 lbs for Toro’s 21-inch single-stage.
• Wheels on a steep drive: Honda and Cub Cadet both point steep or uneven drives to track drive for traction.

How do you use a snow blower safely?

CPSC counted over 4,200 snow blower injuries treated in emergency rooms in 2021 (figures it published in 2023), with over 40% to the wrist, hand and finger. Its safety alert says injuries “most frequently occur” when people clear the auger or chute by hand, including finger amputations. People have also died after getting caught in the machine.

CPSC’s rules:

• Never clear a clog with your hands. Stop the engine and use a cleanout tool or long stick.
• Keep hands and feet away from all moving parts.
• Never leave a gas snow blower running in an enclosed area. CPSC says the exhaust carbon monoxide “can kill in minutes.” Keep working carbon monoxide alarms in the house.
• Refuel outdoors before starting. Never add gas to a running or hot engine.
• Store gas in a capped container with a child-resistant closure, outside the house and away from ignition sources.
• With a corded model, know where the power cord is at all times.
