How to Choose a Pellet Grill: The Specs That Actually Matter

Last reviewed: November 2026. Sources last checked November 2, 2026. We have not tested these grills: specs are what each maker states on its own site.
Five specs separate one pellet grill from another: the controller, how hot it gets and whether it can sear over direct flame, the hopper size, the main grate area, and whether the maker sells the parts that wear out. The controller matters most, because it is what holds your temperature. A PID controller adjusts continuously; a standard one feeds pellets on a timed cycle.
How a pellet grill works
Hardwood pellets sit in a hopper. A motorized auger feeds them to a fire pot, an igniter lights them, a fan feeds the fire air, and a controller decides how fast the auger and fan run. Every spec below is about one of those parts.
The controller
Pit Boss explains the difference plainly: "a standard controller will time the fuel feed to the burn pot to reach desired temperatures," while a PID controller adds Proportional, Integral and Derivative calculations and, Pit Boss says, "senses and adapts to these influences with more speed and precision than a standard temperature controller can," meaning outside heat and wind.
Pit Boss is careful not to oversell it: PID controllers "help regulate temperatures and mitigate swings," and it notes that "there are some that think that the lack of temperature swings can cause less smoke to be produced." So expect a PID grill to swing less, not to hold a perfectly flat line. If a listing doesn't say which controller it has, check the spec sheet before you assume.
Temperature, and searing
Consumer Reports wrote in 2020 that "most max out at around 500° F, while many of the gas and charcoal grills we've tested get as high as 800° F," and concluded that pellet grills are "the perfect fit if you like the taste of smoke and don't care too much about searing." Current maker figures fit that: Traeger's Pro 22 lists up to 450°F and Pit Boss's Sportsman 1100 holds 180° to 500°F.
Some makers add direct-flame searing. Pit Boss's Flame Broiler Lever on the Sportsman 1100 is rated for "a direct flame sear up to 1,000°F." If hard searing matters to you, look for a feature like that or plan on a second grill for high heat.
Hopper size
The hopper decides how long the grill runs before you refill it. Makers list it in pounds, and it varies a lot by model:
| Grill | Hopper (maker) | Cooking area (maker) |
|---|---|---|
| Traeger Pro 22 | 18 lb | 572 sq in on 2 tiers |
| Pit Boss Mahogany Series 820D3 | 21 lb | Not used here |
| Pit Boss Sportsman 1100 | 30 lb | 1,610 sq in |
| Pit Boss Navigator 1150 | 32 lb | 1,158 sq in, which Pit Boss says "holds approximately 46 burgers" |
How long a hopper lasts depends on the temperature you set and the weather, and makers don't publish burn rates on these pages, so compare hoppers against each other rather than counting hours. A clean-out helps: Traeger's Pro 22 has a hopper "clean-out lets you switch pellet flavors quickly."
Cooking area: compare the main grate
Traeger's Pro 22 reaches 572 square inches with "2 tiers" of grates, so the headline figure includes an upper rack. When you compare two grills, look for the main grate area on the spec sheet, and think about what you cook at once. Our guide to what size grill you need works through that with maker figures.
Pellets and shutdown
Keep pellets dry. Traeger says moisture makes them crumbly and that "crumbly pellets can clog the grill's auger and may fail to ignite," and recommends you "keep them dry and airtight." When you finish, let the shutdown cycle run: Traeger says "not allowing this cycle to complete can cause issues with ignition and temperature management during your next cook."

Spare parts
A pellet grill has an auger motor, a fan, an igniter and a control board, and they can wear out. Check that the maker sells them separately for your model: Pit Boss, for example, lists a replacement igniter and auger motor on its own site.
Wi-Fi and probes
Wi-Fi lets you watch and change the temperature from your phone, which helps on an overnight cook. It doesn't make up for a controller that can't hold temperature. Check doneness with a meat thermometer either way. Instant-read thermometers on Amazon
A checklist before you buy
- PID or standard controller? If the listing doesn't say, check the spec sheet.
- Top temperature, and is there a direct-flame sear option if you want one?
- Hopper size in pounds, and is there a clean-out?
- Main grate area, not just the total with upper racks?
- Are the igniter, auger motor, fan and controller sold separately for that model?
