Main trade-off
Traeger Pro Series 34 Pellet Grill
The 18-pound hopper is modest for an 884-square-inch cooker.
Head-to-head
Traeger Pro 34 vs Traeger Pro 780: Pro 34 has more rack area, Pro 780 adds connected controls and higher heat
The short answer
Choose a larger total rack area or connected controls and a higher chamber ceiling.
Before you choose
The reasoning and the trade-offs
Compare total multi-level rack area on the same basis
Pro 34 provides 884 square inches and Pro 780 provides 780. The absolute difference is 104 square inches, or 13.3% of the smaller figure.
What this is based on
884 minus 780 = 104 sq in. 104 ÷ 780 × 100 = 13.3%. Both values include multiple rack levels, so this is not contiguous pan area. No serving count is inferred.
Main trade-off
Traeger Pro Series 780 WiFIRE Pellet Grill
The 18-pound hopper is small relative to the 780-square-inch body for very long high-load cooks.

Winner by situation
Start with what you need it to do
A meal that needs the largest uninterrupted main grate
Pro 34 provides 884 total square inches compared with Pro 780’s 780. The newer-looking number is therefore not the larger stated cooking area. Check each rack’s dimensions before sizing a crowd cook.

A long cook with a planned pellet reserve
Both hoppers hold 18lb, so their nominal fuel capacity is equal. Pro 780’s upgrade is more about its connected controller and 500°F range than extra pellet storage.

Repeated cooks where cleanup and movement matter
Pro 34 stops at 450°F and has no Wi-Fi in this comparison. If most cooking is low-and-slow and the larger racks are genuinely needed, that tradeoff can be reasonable. If remote checks and hotter finishing matter, Pro 780 changes the workflow.

What matters in practice
The differences that matter
Compare total multi-level rack area on the same basis
Pro 34 provides 884 square inches and Pro 780 provides 780. The absolute difference is 104 square inches, or 13.3% of the smaller figure.
How we reached this conclusion
884 minus 780 = 104 sq in. 104 ÷ 780 × 100 = 13.3%. Both values include multiple rack levels, so this is not contiguous pan area. No serving count is inferred.
A stated pellet-burn assumption makes the hopper comparison usable
Pro 34’s larger total rack area comes with the same 18lb hopper as Pro 780. Each represents 12 hours at the illustrative rate, so extra food area does not imply extra fuel endurance.
How we reached this conclusion
Assume the same constant 1.5lb/h consumption solely to normalize hopper size. 18 ÷ 1.5 = 12h. 18 ÷ 1.5 = 12h. Actual use varies with temperature, weather, food and grill design. This is not an unattended-use recommendation.
The Pro 34 has 104 more total square inches
The difference is 884 minus 780, giving Pro 34 about 13.3% more stated area relative to Pro 780.
How we reached this conclusion
884 minus 780 = 104. 104 ÷ 780 × 100 = 13.3%. The total includes upper-level space and cannot be converted directly into servings.

How to make the call
Size the food on the actual racks
Pro 34 provides 884 total square inches compared with Pro 780’s 780. The newer-looking number is therefore not the larger stated cooking area. Check each rack’s dimensions before sizing a crowd cook.
Separate fuel capacity from cooking temperature

What this comparison cannot tell you
- Pellet-duration estimates use a stated illustrative burn rate. They are not measured runtime or permission to leave a grill unattended.
- Rack totals do not establish a serving count or the fit of a single large item.
- No smoke-flavor, temperature-stability or searing-performance test is claimed.
