How we calculate
- Time range = weight × hours per pound from the sources below (ribs, chicken, tri-tip and belly are timed per piece).
- The plan sits 60% of the way from the short end to the long end. Finishing early is easy to fix with a longer rest; finishing late is not.
- Several pieces: time follows the biggest one, plus 10% when the smoker holds 3 or more.
- Wrapping: where a source gives wrapped times we use them; otherwise we take about 10% off for butcher paper and 20% for foil (our estimate).
- Light the smoker at: plan + rest + a 1-hour buffer + 45 minutes to light and settle it. Cooked yield is from the USDA Food Buying Guide.
- Spare ribs: our source gives one 5–6 hour estimate for pork ribs; we use it at both 225 and 250°F.
Sources disagree by an hour or more on big cuts; that spread is why we show a range. Always finish by internal temperature. Data as of Oct 2026. Full list of sources: How we calculate.
