Smoking Time Calculator
Pick the meat, the weight and your pit temperature, then tell us when you want to eat. You'll get an estimated cook time and a cook-day timeline, from lighting the fire to slicing.
Your plan
Estimated cook time
13–16¼ hr
Estimated cook time at 250°F, plus 60–120 min to rest.
Done when: 200–205°F and probe-tender
- Light the smoker and wait for thin blue smoke (day before)
- Meat on at 250°F
- Wrap at 165–175°F once the bark is set
- Start checking for doneness: 200–205°F and probe-tender
- Latest finish; rest (hold it wrapped if it's early)
- Slice and serve
How the calculator works
For big cuts, cook time scales with weight. The calculator multiplies the weight by a per-pound range for your pit temperature, based on widely used rules of thumb, then plans backward from your dinner time using the long end of the range plus the rest. Ribs and salmon cook by thickness rather than weight, so they use a fixed range.
| Cut | 225°F | 250°F | 275°F | Done at |
|---|---|---|---|---|
| Brisket (packer) | 1¼–1½ hr/lb | 1–1¼ hr/lb | ¾–1 hr/lb | 200–205°F, probe-tender |
| Pork butt | 1½–2 hr/lb | 1¼–1½ hr/lb | 1–1¼ hr/lb | 195–203°F |
| Chuck roast | 1½–1¾ hr/lb | 1¼–1½ hr/lb | 1–1¼ hr/lb | 200–205°F |
| Spare ribs | 5½–6½ hr | 5–6 hr | 4–5 hr | Bend test, about 200°F |
| Baby back ribs | 4½–5½ hr | 4–5 hr | 3½–4¼ hr | Bend test, about 200°F |
Why your cook might run long (or short)
- The stall. Brisket and pork can sit at 150–170°F for hours. Wrapping shortens it.
- Your thermometer. If the lid dial reads 250°F, the grate might be 225°F. Measure at grate level.
- Thickness beats weight. A thick 10 lb brisket can take longer than a long, thin 12 lb one.
- Weather. Wind, rain and cold pull heat out of thin-walled smokers.
- Peeking. Every time the lid opens, the smoker loses heat and needs time to recover.
A wrapped brisket or pork butt holds for 3–4 hours in a dry cooler and keeps getting better. Finishing early is a feature. Finishing late means hungry guests.

Cook time FAQ
How long does it take to smoke a brisket?
About 1 to 1¼ hours per pound at 250°F, so 12–16 hours for a 12–14 lb packer, plus at least an hour of rest. At 275°F it's closer to ¾–1 hour per pound.
How long does it take to smoke a pork butt?
About 1¼–1½ hours per pound at 250°F, so roughly 10–13 hours for an 8–9 lb bone-in butt, plus an hour of rest.
Is it better to smoke at 225°F or 250°F?
Both work. 225°F gives a little more time for smoke and a very gentle cook; 250°F finishes sooner with nearly identical results. Many pitmasters now smoke brisket at 250–275°F.
What if my meat finishes early?
Wrap it tightly, wrap it again in old towels, and put it in a dry cooler. Brisket and pork butt hold above 140°F for 3–4 hours and often taste better for it.
Why does the calculator give a range?
Every piece of meat is different, and so is every smoker. Plan with the long end of the range, then cook to temperature and tenderness.
