Plan your brisket cook backward from dinner time. Enter the weight, smoker temperature and how you wrap, and get the estimated cook time including the stall, when to light the smoker and put the brisket on, when to wrap and pull, and how long to rest.

How to use the Brisket Smoking Time Calculator
Enter the raw weight and choose whole packer, flat or point.
Pick your smoker temperature and wrap method.
Set the serving day and time, rest length and a safety buffer.
Read the start time: when to trim, light the smoker and put the brisket on.
Cook to feel, not the clock: pull when it probes tender around 200–205°F.

Unwrapped times shown; butcher paper usually takes 10–15% off and foil about 20–25%. The calculator splits the cook into three parts: the climb to about 160°F (~40% of an unwrapped cook), the stall (~30%) and the finish to 200–205°F (~30%). Wrapping shortens the stall the most. Thickness, fat cap, smoker airflow, weather and how often you open the lid all move the real time, so treat the result as a plan, not a promise.
Brisket temperatures to know
150–170°F: the stall. Do not crank the heat; wrap once the bark is dark and firm if you want to push through.
160–170°F: typical wrap point in butcher paper or foil.
195–205°F: start probing for tenderness in the flat.
Above 140°F: the minimum for holding cooked meat hot (USDA). Below that, refrigerate within 2 hours.
Tips for a better brisket
Trim the fat cap to about 1/4 in and round off thin edges that would burn.
Season the night before with coarse salt and pepper (a 50/50 mix by volume is the Texas classic).
Use a leave-in probe in the thickest part of the flat and a separate thermometer at grate level; built-in lid gauges can be 25°F off.
Plan to finish early. A brisket holds beautifully for hours; a late brisket cannot be rushed.
Frequently asked questions
How long does it take to smoke a brisket?
A common rule is 1 to 1 1/2 hours per pound at 225-250°F. A 14 lb packer takes roughly 17-18 hours at 250°F unwrapped, or about 15 hours wrapped in butcher paper. At 275°F expect about 1 hour per pound. Every brisket is different, so plan a range and a long hold.
What is the brisket stall?
Around 150-170°F internal, the temperature can stop rising for hours. Moisture evaporating from the surface cools the meat as fast as the smoker heats it. Wrapping in butcher paper or foil once the bark is set traps the moisture and shortens the stall.
Butcher paper or foil: which is faster?
Foil (the Texas crutch) is faster because it seals in moisture, but it softens the bark. Butcher paper breathes, keeps a firmer bark and saves a bit less time. This calculator assumes paper cuts total cook time by roughly 13% and foil by roughly 22% compared with unwrapped.
What temperature is brisket done?
Most briskets are tender at about 200-205°F internal, but the real test is feel: a probe or skewer should slide into the thickest part of the flat with almost no resistance. Some are ready at 195°F, others need 210°F.
How long should brisket rest?
At least 1 hour, and 2-4 hours is better for a whole packer. Wrap it and hold it in a dry cooler lined with towels or in an oven at 150-170°F. Keep it above 140°F for food safety; a well-wrapped brisket in a cooler stays hot for 4 hours or more.
When should I start smoking a brisket for dinner?
Count back from serving time: slicing (15 min), rest and hold (2-3 h), the cook itself (about 1-1 1/2 h per lb) and smoker warm-up (about 45 min). For a 6 p.m. dinner with a 14 lb brisket at 250°F that is usually between 10 p.m. and 1 a.m. the night before.
How much brisket per person?
A whole brisket loses about half its weight to trimming and cooking. Plan on 1/3 lb of cooked brisket per person, or roughly 2/3 lb of raw brisket per person. A 14 lb packer yields about 7 lb cooked, enough for around 20 people.
