Smoking Time Calculator

Estimate how long to smoke brisket, pork shoulder, ribs, chicken, and more — with wrap temps and target internal temps.

Time scales with weight.

internal temp — to push through the stall
  • Smoking times are estimates only — the weather, your smoker, and how the meat behaves all matter. Plan a generous buffer and hold finished meat wrapped in a cooler if it finishes early.
  • Expect "the stall" around 165°F internal, when evaporative cooling parks the temperature for an hour or more. Wrapping in foil or butcher paper at that point powers through it.
  • Cook to 203°F internal, checked with a thermometer in the thickest part — collagen-rich cuts like brisket and pork shoulder need that high temperature to render fully tender.
  • This target meets or exceeds the USDA-safe minimum. Poultry must reach 165°F; whole pork and beef cuts are safe at 145°F but are taken much higher here for texture.
  • Rest large cuts at least 30–60 minutes before slicing or pulling so the juices settle back into the meat.

How to use this calculator

  1. Choose the cut

    Select your cut — brisket, pork shoulder, ribs, chicken, turkey, pork tenderloin, or beef short ribs.

  2. Enter the weight

    For weight-based cuts like brisket and pork shoulder, type the weight in pounds. Fixed-time cuts like ribs do not need a weight.

  3. Read the time and temperatures

    The calculator gives an estimated smoke time, the recommended smoker temperature, the wrap temperature, and the target internal temperature.

  4. Smoke to temperature, not the clock

    Use a thermometer to track the internal temperature, wrap when the meat stalls, and pull it when it hits the target.

Times are estimates — the stall and weather vary widely. USDA-safe minimums: poultry 165°F, whole pork/beef cuts 145°F (collagen-rich cuts here are taken higher for texture).

Tips & best practices

  • Cook to internal temperature, never to time — a thermometer is the single most important tool for barbecue.
  • Always build in a buffer. It is far easier to hold finished meat warm in a cooler than to rush a stalled brisket for guests.
  • Wrap at the stall to push through it faster: foil for speed, butcher paper to protect the bark.
  • Keep your smoker temperature steady — spikes and dips stretch the cook time and dry out the meat.
  • Spritz with water, apple juice, or vinegar during long smokes to keep the surface from drying before the bark sets.
  • Hold finished brisket or pork shoulder wrapped in a towel-lined dry cooler — it stays hot and safe for hours and actually improves.

Frequently asked questions

How long does it take to smoke a brisket?
At 225°F, plan on roughly 1 to 1.5 hours per pound. A 12-pound brisket can take 12 to 18 hours. Brisket is notoriously unpredictable because of the stall, so always cook to an internal temperature of about 203°F rather than to the clock.
What is 'the stall' when smoking meat?
The stall is a long plateau, usually around 150–165°F internal, where evaporative cooling from the meat's surface balances the heat going in and the temperature stops climbing for an hour or more. Wrapping the meat in foil or butcher paper traps moisture and pushes through it.
What temperature should I smoke pork shoulder to?
Smoke pork shoulder (Boston butt) at 225°F for about 1.5 hours per pound, and cook it to an internal temperature of around 203°F. That high finish temperature is what renders the collagen and lets the meat pull apart easily.
How long do I smoke ribs?
At 225°F, baby back ribs take about 5 to 6 hours and spare ribs about 6 to 7 hours. Ribs are done when the meat has pulled back from the bone and an internal temperature of roughly 195–203°F renders them tender.
What internal temperature is safe for smoked poultry?
All poultry must reach the USDA-safe minimum of 165°F in the thickest part. Smoke a whole chicken at 250°F for about 3 to 4 hours, and a whole turkey at 275°F for roughly 30 minutes per pound.
Should I wrap my brisket or pork shoulder?
Wrapping at the stall (around 160–165°F internal) speeds up the cook and keeps the meat moist. Foil wraps tightest and is fastest; butcher paper breathes a little, protecting the bark. Wrapping is optional but most pitmasters do it.
Why is my smoke taking longer than the estimate?
Cold weather, wind, opening the lid, a colder-than-expected cut, and a long stall all add time. This is normal in barbecue. Start early, and if the meat finishes ahead of schedule, wrap it and hold it in a dry cooler for an hour or more.
Do I need to rest smoked meat?
Yes. Rest large cuts like brisket and pork shoulder at least 30–60 minutes, loosely wrapped, before slicing or pulling. Resting lets the juices redistribute so they stay in the meat instead of pooling on the cutting board.
