A typical bag of Traeger pellets weighs 20 pounds.
Depending on your cooking temperature, that bag can power anywhere from 6 to about 20 hours of grilling or smoking.
The burn time of a bag can vary quite a bit, which often surprises new pellet grill owners.
The reason is simple: pellet grills burn fuel based on temperature.
The hotter you cook, the faster pellets disappear.
Understanding how long a bag lasts helps you plan long cooks, avoid running out of fuel, and estimate how many bags you’ll use in a grilling season.
The Average Burn Time of a 20-Pound Bag
Most pellet grills burn pellets at a steady rate that changes with temperature.
A good rule of thumb is about 1 pound per hour at low smoking temperatures and 2–3 pounds per hour at higher heat.
Here’s how that usually looks during real cooks:
At 225°F (low and slow smoking)
A grill may burn around 1 pound per hour.
That means a 20-pound bag could last 18–20 hours.
At 300°F (roasting or standard grilling)
Pellet use increases to roughly 1.5 pounds per hour.
A bag will last around 13–15 hours.
At 400°F or higher
Fuel use jumps to about 2–3 pounds per hour. In this range, a bag may last 6–10 hours.
These numbers apply to most grills from Traeger and similar pellet grill brands.

The Type of Pellets You Use Matters
Pellet quality can slightly affect burn time.
Well-compressed hardwood pellets tend to burn more consistently and produce less dust.
A common option is Traeger Signature Blend All-Natural Hardwood Pellets, which combine hickory, maple, and cherry for balanced smoke flavor.
Blended pellets like this are designed for steady combustion and all-purpose cooking.
While they won’t dramatically change burn time, they can produce more predictable results than low-quality pellets.

What Real Cooks Look Like
Looking at typical barbecue sessions helps make burn time easier to understand.
A rack of ribs usually cooks for about five hours at 225°F.
That cook might use five to six pounds of pellets, meaning a single bag could cover several rib cooks.
A pork shoulder often takes 10–12 hours.
That cook may use 10–12 pounds of pellets, or roughly half a bag.
Brisket cooks can run even longer, often between 12 and 16 hours.
A full brisket session may use most of a 20-pound bag, especially if the temperature increases near the end.

Short weeknight cooks like burgers, chicken thighs, or vegetables use very little fuel.
In those cases, one bag can last through many meals.
Weather Can Change Burn Time
Outdoor conditions have a bigger impact on pellet use than many people expect.
Cold weather forces the grill to burn more fuel to maintain temperature.
Wind can also increase pellet consumption because heat escapes from the cooking chamber.
A grill running at 225°F during summer may burn close to 1 pound per hour.
The same grill in winter conditions could burn closer to 1.5 pounds per hour.
That doesn’t mean pellet grills struggle in cold weather.
It simply means they work harder to hold temperature.
Hopper Size vs Bag Size
Most pellet grills have hoppers that hold 18 to 22 pounds of pellets, which is roughly one full bag.
This design makes refueling simple.
You can pour an entire bag into the hopper before a long cook and avoid checking fuel levels constantly.
However, it’s still smart to glance at pellet levels during extended cooks like brisket or pork shoulder.
Running out of pellets will extinguish the fire and require a restart.

Flaws but Not Dealbreakers
Pellet grills are efficient, but they do rely on consistent fuel supply.
The main drawback is that pellet consumption isn’t always obvious.
Because pellets sit inside the hopper, it’s easy to forget how much fuel remains during long cooks.
Another small limitation is that high-heat grilling burns pellets quickly.
If you frequently cook steaks or pizza at 450°F or higher, you’ll go through bags faster than someone who mostly smokes ribs and brisket.
These trade-offs are minor compared with the convenience pellet grills provide.
The Bottom Line
A standard 20-pound bag of Traeger pellets usually lasts between 6 and 20 hours, depending on temperature and weather conditions.
Low-and-slow smoking stretches a bag the farthest.
High-heat grilling burns through pellets quickly.
Most backyard cooks find that one bag covers several meals, while longer barbecue sessions may use most of a bag in a single day.
Planning ahead, and keeping an extra bag nearby, helps ensure your cook never runs out of fuel halfway through.
