How big of a pellet grill hopper do I need?

For most backyard cooks — even an overnight brisket — an 18-24 lb hopper is enough, since pellet grills typically burn 1-3 lb of fuel per hour depending on temperature and outside conditions. If you regularly run cooks past 15-20 hours, cook for a crowd, or hate refilling mid-smoke, step up to a 30-40 lb horizontal grill like the Recteq RT-700, or a vertical smoker with a 60-65 lb hopper built for multi-day runs.

How long does a hopper of pellets actually last?

It depends on both hopper size and temperature, but real testing gives useful anchors: Smoked BBQ Source clocked 8+ hours on the Pit Boss Pro Series 850's 22 lb hopper without a refill, Food Fire Friends measured 15-25 hours on the Z Grills Multitasker's 28 lb hopper, and Recteq states roughly 30 hours on the RT-590's 30 lb hopper and 40 hours on the RT-700's 40 lb hopper. As a rule of thumb, divide hopper capacity by 2 lb/hour (a reasonable mid-range burn rate) to estimate your own runtime, then adjust down for high-heat searing or cold weather.

Do vertical pellet smokers have bigger hoppers than horizontal grills?

Yes, usually by a wide margin. Most horizontal pellet grills carry 18-40 lb hoppers, but vertical cabinet smokers are built for multi-day, multi-rack cooks and typically carry 60-75 lb hoppers — the Pit Boss Pro Series II 4-Series holds 65 lb, the Pit Boss Navigator 6-Series holds 75 lb, and the Louisiana Grills 7-Series holds 60 lb, per each manufacturer's specs. The trade-off is that verticals smoke and roast but generally can't sear.

What happens if a pellet grill runs out of pellets mid-cook?

The fire goes out once the auger runs dry, and most controllers will eventually throw a low-temperature error code (like Traeger's LEr or Pit Boss's Er2) rather than silently restarting once you add more fuel — see our pellet grill maintenance guide for what those codes mean. Refilling mid-cook is safe: open the hopper lid, add pellets, and most controllers resume automatically, though very cheap electronics may need a manual Prime cycle to get the auger feeding again.

Does a bigger hopper mean a bigger grill?

Not always, but usually. Hopper size tends to scale with cook space because bigger grates burn more fuel per hour to hold temperature — the Recteq RT-700's 40 lb hopper backs 702 sq in of cook space, for example. The exceptions are vertical smokers, which pack a large hopper into a narrow cabinet footprint, and portable searing grills like the Recteq Bullseye Deluxe, which stays compact at 380 sq in but still needs an 18 lb hopper to sustain 1,000°F direct-flame heat.

Pellet Grill Hopper Size Guide (2026): How Many Pounds Do You Actually Need?

Every pellet grill spec sheet lists a hopper capacity in pounds, but almost none of them tell you what that number means for your actual cook — whether an 18 lb hopper gets you through an overnight brisket, or whether you’ll be adding pellets at 3 a.m. We pulled the real hopper capacities and tested runtimes across every brand this site covers so you can match hopper size to how you actually cook, instead of guessing from a spec sheet.

Quick Answer

Most backyard pellet grills carry an 18-24 lb hopper, which is enough for 8-12 hours of typical low-and-slow cooking since pellet grills burn roughly 1-3 lb of fuel per hour depending on temperature and weather. That covers the vast majority of cooks, including a standard overnight brisket. If you regularly run 15+ hour smokes, cook for a crowd, or want to skip refills entirely, look at a 30-40 lb horizontal grill — Recteq states roughly 40 hours of runtime on the RT-700’s 40 lb hopper — or a purpose-built vertical smoker, where hoppers commonly reach 60-75 lb for genuine multi-day capacity.

How much pellet does a pellet grill actually burn?

Expect to burn roughly 1-3 lb of pellets per hour, with low-and-slow smoking near the bottom of that range and high-heat grilling or searing near the top. That single number is the reason hopper math is simple: divide hopper capacity by your expected burn rate to estimate runtime. A 22 lb hopper at a middling 2 lb/hour rate lasts about 11 hours — plenty for most overnight cooks, but tight for a 16-hour packer brisket smoked low and slow the whole way. That’s exactly why Recteq’s own 40-hour claim on the RT-700 works out cleanly: a 40 lb hopper at roughly 1 lb/hour of low-temperature smoking gets you there.

Extra sealed pellet storage bucket

Backup fuel that stays dry between refills

A gasket-sealed bucket keeps a spare 20 lb bag ready to top off the hopper mid-cook without exposing it to garage humidity.
Cheaper insurance than an auger jam from swollen, moisture-damaged pellets.
Keep it near the grill, not just in storage, so a mid-cook refill takes seconds.

Do you need a bigger hopper, or just fewer refills?

Most shoppers overthink hopper size because they’re picturing an unattended overnight cook, but the math above shows an 18-24 lb hopper covers the large majority of real backyard sessions — a rack of ribs, a pork butt, even most briskets. Where a bigger hopper actually earns its keep is the small set of cooks that run past 15-20 hours, feed a large group, or happen in cold weather, where the fire has to work harder and burns fuel faster to hold temperature. If that’s an occasional situation rather than your default cook, a 20-24 lb hopper and a bag of backup pellets nearby solves it cheaper than buying a bigger grill.

Vertical smokers solve the hopper problem differently

Instead of scaling a horizontal grill’s hopper up to absurd sizes, most brands solved multi-day capacity with a different shape entirely: a vertical cabinet smoker. The Pit Boss Pro Series II 4-Series carries a 65 lb hopper, per Pit Boss, and the Navigator 6-Series steps up to 75 lb — both multiples of what a horizontal grill in the same price range carries. Louisiana Grills’ 7-Series pushes the endurance angle further, rated for up to 35 hours of runtime on its 60 lb hopper, per Louisiana Grills — a full competition weekend on one fill. The trade-off is real: verticals stack racks for volume smoking and roasting, but none of them sear. Our best vertical pellet smoker guide ranks all six of these cabinets in detail.

Hopper runtime by the numbers

Metric	Figure	Source
Typical pellet burn rate	1-3 lb/hour	Site-wide BBQ testing consensus
Pit Boss Pro Series 850 (22 lb hopper)	8+ hrs tested, no refill	Smoked BBQ Source
Z Grills Multitasker (28 lb hopper)	15-25 hrs per fill	Food Fire Friends
Recteq RT-590 (30 lb hopper)	~30 hrs per fill	Recteq
Recteq RT-700 (40 lb hopper)	~40 hrs per fill	Recteq
Louisiana Grills 7-Series (60 lb hopper)	up to 35 hrs per fill	Louisiana Grills

The spread in these numbers — 8 hours on a 22 lb hopper versus 40 hours on a 40 lb hopper — isn’t purely proportional to capacity, because temperature and grill design change the burn rate too. That’s the real lesson: hopper capacity in pounds is only half the story, and matching it to your actual cook length matters more than chasing the single biggest number on a spec sheet.

Which hopper size should you buy?

Weeknight cooks, ribs, or a single roast: 18-20 lb is plenty — don’t pay extra for capacity you won’t use.
Overnight brisket or pork butt, occasionally: 22-24 lb covers nearly every real-world overnight cook.
Frequent 15+ hour smokes or feeding a crowd: step up to a 28-40 lb horizontal grill like the Z Grills 700D4E or Recteq RT-700.
Multi-day competition-style cooks: a vertical smoker’s 60-75 lb hopper is purpose-built for this, at the cost of searing ability.
Tailgating or small patios: an 18 lb portable hopper, like the Recteq Bullseye Deluxe, is a feature, not a compromise, once you know your real cook length.
