2 smaller birds beat one giant every time at smoker temps: they clear the 40–140°F danger zone faster, cook more evenly, and give you 4 drumsticks instead of 2.
Assumes 25 adults, a full holiday table of sides, no leftovers planned.
Twenty-five is a room, not a table, and rooms eat differently: people take smaller first plates and more of them come back. Twenty-five adults work out to roughly twelve and a half pounds of meat, which is two large birds with a little headroom — and the headroom matters, because at this size running out is a genuinely public failure.
The maths, step by step
1. Meat needed 25 adults × 0.5 lb = 12.5 lbs
2. Less 20% for a full table of sides 12.5 × 0.8 = 10 lbs
3. Raw weight (a whole bird is ~40% meat) 10 ÷ 0.4 = 25 lbs raw

Sides move this number more than anything else, and leftovers are a deliberate choice rather than an accident.

Kids under 12 eat about 0.25 lb each — half an adult portion. Swapping four of your 25 adults for four kids takes roughly 2 lbs off the raw weight.
Cooking for 25: what actually goes wrong
The bottleneck here stops being the smoker and becomes the carving. Turkey dries much faster than brisket once it is off the bone, so carve one bird, put it out, and leave the second whole and tented until the first platter is visibly going. A carved bird sitting under a heat lamp for forty minutes is a worse dinner than one carved late.
How long it takes
At 275°F — the temperature worth using, because it is the one that crisps the skin — a 14 lb bird takes about 4 h 40 m on the smoker, plus a 30-minute rest. Full timeline and start times on the 14 lb at 275°F page, or use the calculator to work backwards from your own carving time.

Common questions
How much turkey do I need for 25 people?
+
For 25 adults with a full holiday table, buy about 25 lbs of whole turkey — 2 birds, ~13 lb each. That yields roughly 10 lbs of servable meat, because a whole bird is only about 40% meat once bone, skin and carcass are removed. With only a couple of sides, go up to 31.5 lbs.
What size turkey for 25 guests?
+
2 birds, ~13 lb each 2 smaller birds beat one giant every time at smoker temps: they clear the 40–140°F danger zone faster, cook more evenly, and give you 4 drumsticks instead of 2.
How much turkey for 25 people if I want leftovers?
+
Add about 30% and buy 32.5 lbs instead of 25 lbs. Turkey leftovers are the one holiday leftover people genuinely plan for, so this is rarely wasted.
Could I smoke bone-in breasts instead for 25 people?
+
Yes, and it is often the smarter buy. A bone-in breast is about 65% meat against a whole bird's 40%, so 25 guests need only about 15.5 lbs of breast — 3 bone-in breasts, ~5.5 lb each. You lose the drumsticks and the centrepiece, and you gain time, oven space and all white meat.
