How this calculator works
- Area. Length x width, or cars x 200 sq ft (a 10 x 20 ft space; makers that quote "N-car driveways" do not publish theirs), plus walkways at 4 ft wide.
- Stage. Maker guidance: single-stage augers touch the ground, so they are for paved surfaces and moderate snow. We move to two stage for gravel, storms over 8 in, a plow berm, heavy wet snow over 6 in, a steep driveway (self-propelled drive) or 3,000 sq ft and up. Storms of 18 in or more, or lake-effect totals with a long driveway and berm, point to three stage or a 28 in+ two stage.
- Width and intake. Our bands: 18 in under 800 sq ft, 20 in to 1,600, 21 in to 3,000, 24 in to 6,000 and 28 in beyond; two stage starts at 24 in. Intake height should match your storm depth; with a plow berm we look for the 20 in intake of a two stage. Deeper snow takes extra layers.
- Time to clear. Area / (width x 85% for overlap x pace), plus 25% for turns and chute changes. Pace is our assumption: 1.0 mph, or 0.6 mph in deep or heavy wet snow.
- Battery. EGO publishes how many cars of 8 in snow each kit clears per charge (10 for two 4 Ah packs up to 32 for two 12 Ah). That averages about 45 Wh per car, which we use for brands that publish no claim. We scale by depth (8 in = 1x, with a 4 in floor) and by snow type: heavy wet 1.5x and powder 0.8x, since the National Weather Service puts wet snow at roughly twice the water content of average snow. A blower that needs more than two charges is left out; between one and two, the kit adds a spare on the same battery platform.
- Cord and engine. Corded blowers only when the driveway is within 100 ft, Snow Joe's extension cord limit. Engine size starts from what makers pair with each width (208 to 212 cc on the 24 and 26 in machines we list, 302 cc on the 30 in); for heavy wet snow or a berm we suggest one step up, 250 cc or more at 26 in and wider.
Worked examples
Two-car paved driveway, 6 in storms
- 20 x 24 ft paved driveway plus 30 ft of walkway (600 sq ft)
- 6 in typical storm, about 30 in a year
- No plow pile, any power
A single stage, 18 in or wider. About 6 minutes with a 20 in corded blower.
Paved, under 8 in and no plow berm keeps it single stage. 600 sq ft at 1.0 mph with a 20 in path (85% overlap) plus 25% for turns is about 6 minutes. The Westinghouse WSnow20 ($100 to $250) is the cheapest fit if an outlet is within 100 ft. On battery, the Snow Joe 48V kit uses about 42% of its 240 Wh at this depth.
Four-car driveway with a plow berm, battery only
- 60 x 20 ft paved plus 40 ft of walkway (1,360 sq ft)
- 8 in storms, about 50 in a year
- Street plow leaves a pile; battery power
A two stage, 24 in wide with a 20 in intake. One charge of the EGO SNT2405 covers it.
The packed berm at the end is what pushes this to two stage. 1,360 sq ft is 6.8 car spaces of 200 sq ft; at 8 in that is 38% of the 18 cars EGO rates the SNT2405 ($1,000 to $2,000) for on one charge of its two 7.5 Ah batteries. About 11 minutes to clear.
Long gravel driveway, heavy wet snow
- 120 x 20 ft gravel (2,400 sq ft)
- 12 in storms of heavy wet snow, about 80 in a year
- Plow pile, any power
A two stage, 24 in or wider with a 212 to 250 cc engine. About 33 minutes per storm.
Gravel alone rules out single stage. Wet 12 in snow slows you to about 0.6 mph, so a 24 in path takes about 33 minutes. The PowerSmart 24 in 212cc ($500 to $1,000) is the cheapest fit; on battery, the EGO SNT2405 needs about 1.5 charges at this depth and weight, so the kit adds a spare EGO 2-pack.
Frequently asked questions
What size snow blower do I need for a two-car driveway?
A two-car driveway is about 400 to 600 sq ft. If it is paved, gets under 8 in per storm and has no plow pile, an 18 to 21 in single stage clears it in under 10 minutes. Gravel, deeper storms or a plow berm call for a 24 in two stage.
Single stage or two stage snow blower?
Single stage for paved driveways with storms under about 8 in: the auger touches the pavement and throws the snow itself. Two stage for gravel, deep or heavy wet snow and the plow berm: the auger feeds an impeller and the housing rides on skid shoes above the surface.
Can you use a single stage snow blower on gravel?
No. A single-stage auger scrapes the surface, so it picks up stones and throws them. Use a two stage with the skid shoes set so the scraper bar rides above the gravel, and wait until the ground is frozen or packed for the first pass.
What is a three stage snow blower?
A two stage with an extra accelerator auger ahead of the impeller, sold by Cub Cadet and Troy-Bilt. It chews through deep drifts and plow berms faster. For storms past about 18 in or lake-effect winters with a long driveway it is worth a look; a 28 in or wider two stage does most of the same work.
How many batteries do I need for a cordless snow blower?
Check the maker's claim. EGO rates its blowers at 10 to 32 cars of 8 in snow per charge, depending on the batteries included. Double the depth or switch to heavy wet snow and you use roughly twice the battery. This calculator works out the charges for your area and adds a matching spare set when one charge is not enough.
How long does it take to snow blow a driveway?
Area / (clearing width x walking pace). At about 1 mph with 15% overlap and time for turns, a 20 in blower clears 600 sq ft in about 6 minutes and a 24 in two stage clears 2,400 sq ft of heavy wet snow in about 33 minutes.
What cc engine do I need on a gas snow blower?
The 24 and 26 in two-stage blowers we list use 208 to 212 cc engines, which covers a typical two to four-car driveway. Our rule for 26 in and wider in heavy wet snow or with a plow berm is 250 cc or more; the 30 in machine here runs 302 cc.
Is a corded electric snow blower worth it?
For a short paved driveway and walks within 100 ft of an outlet, yes: they are the cheapest and need no gas or batteries. Snow Joe says not to use more than 100 ft of extension cord. They are single stage, so not for gravel, deep snow or the plow pile.
