Quick Answer: The Ooni Karu 2 Pro bakes 16-inch pizzas on a 17-inch floor, ships with the Ooni Connect Digital Temperature Hub, and lists at $849 ($989 once you add the required-for-gas $140 burner). The Ooni Karu 2 bakes 12-inch pizzas, weighs just under 34 lb — less than half the Pro’s 62.6 lb — and lists at $449 ($570 with gas). Both burn wood and charcoal out of the box and both hit 950°F, so pizza quality is identical; the decision is really about how many people you feed and whether you’ll ever carry the oven anywhere. Buy the Karu 2 Pro for a crowd or for roasting beyond pizza; buy the Karu 2 for one to four people and true portability.
The Karu 2 and Karu 2 Pro are Ooni’s current multi-fuel pair — the ovens that replaced the older Karu 12/12G and Karu 16 naming in the 2026 lineup. Both burn real wood and charcoal, both wear the same ClearView borosilicate glass door, and both reach the same peak heat. Here’s what actually separates them, and which one earns its price.
Karu 2 vs Karu 2 Pro by the numbers
- 950°F (500°C): the rated ceiling for both ovens, per Ooni — comfortably above the ~905°F (485°C) deck temperature the Associazione Verace Pizza Napoletana specifies for certified Neapolitan pizza, and far past the roughly 550°F a typical home kitchen oven reaches, per the U.S. Department of Energy.
- 12” vs 16”: max pizza size — the Karu 2 Pro’s 17-inch cooking surface fits a full 16-inch pie, the Karu 2 tops out at 12 inches.
- 34 lb vs 62.6 lb: unboxed weight, per Ooni’s spec sheets — the Pro is nearly double, which is the single biggest reason the two ovens serve different buyers.
- $449 vs $849: list price for the wood-and-charcoal oven alone; add the separate gas burner and it’s ~$570 vs $989 for a genuinely multi-fuel setup on either model.
- 30-40 minutes: the real-world preheat Pala Pizza measured on the Karu 2 Pro’s gas burner at 44°F ambient, against Ooni’s 15-minute spec-sheet claim for both ovens — a useful reminder to check the stone, not the clock, on either model.

Size, and what it actually feeds
This is the real decision. The Karu 2 Pro’s 17-inch floor fits a full 16-inch pizza, roughly 75% more surface area than the Karu 2’s 12-inch limit — enough room to feed a family or a small party without a second oven running. The standard Karu 2 is plenty for one to four people, and its smaller chamber actually preheats and recovers faster between bakes, which matters more on a weeknight than headline size does.
Ooni Karu 2 Pro — for families & entertaining
- 17" cooking surface fits a full 16" pizza — 75% more room than the Karu 2.
- Ooni Connect Digital Temperature Hub and food probe included in the box.
- Tallest Ooni chamber (~5.7"), so it also handles whole chickens and deep-dish.
Feeding a crowd means restocking the pantry, too — Amazon Fresh can have the mozzarella and San Marzano tomatoes on the porch before the oven even hits temperature.
The included hub only tells half the story
The Karu 2 Pro’s Ooni Connect hub is a genuine perk — on the standard Karu 2 it’s an accessory you’d buy separately. But read what it actually measures: chamber air temperature, plus a food probe for roasts. It has no stone thermocouple on either oven. Instrumented testing of Ooni’s related G2-burner Koda 2 found a roughly 90-100°F gap between chamber air and stone surface — a hub that reads air will say the oven is ready while the stone underneath is still short, on the Pro or the standard Karu 2 alike. An infrared thermometer closes that gap on either model.
Weight and portability
The Karu 2 wins outright: at just under 34 lb it folds and travels to a tailgate or campsite the way the Pro never will. The Karu 2 Pro at 62.6 lb is movable on its legs but is realistically a patio or cart-resident oven — Pala Pizza’s own testing flagged the folding legs releasing too easily during a lift, one more reason not to plan on carrying this one far. If travel matters more than pizza size, the Karu 2 is the correct answer before you even look at price.
Ooni Karu 2 — for value & portability
- Just under 34 lb — genuinely portable to a campsite or tailgate.
- Same 950°F ceiling and 60-second Neapolitan bake as the Pro.
- Roughly half the all-in price of a gas-equipped Karu 2 Pro.
Price you should actually budget
Both ovens quote a wood-and-charcoal sticker price that undersells what “multi-fuel” costs. The Karu 2 lists at $449 but runs about $570 once you add its gas burner; the Karu 2 Pro lists at $849 but runs $989 with its $140 burner. That $419 all-in gap is the real spread between the two ovens — bigger than the sticker prices alone suggest, and worth having in mind before you compare either one against a gas-native oven like the Ooni Koda 16 or Koda 2 Pro.
Who should buy which
Buy the Karu 2 Pro if you regularly cook 16-inch pizzas for four or more people, want the tallest Ooni chamber for roasts alongside pizza, or specifically want the Connect hub included rather than bought separately.
Buy the Karu 2 if you cook for one to four people, want an oven that genuinely travels, or want the same 950°F wood-fired flavor for roughly half the all-in price. For most home cooks weighing this exact matchup, the standard Karu 2 is the oven most people should actually buy — the Pro earns its premium specifically for size and ceiling height, not for cooking quality.

The bottom line
Pick the Ooni Karu 2 Pro if 16-inch pizzas for a crowd, the tallest chamber, and an included temperature hub matter more to you than $400 and 29 lb. Pick the Ooni Karu 2 if you cook for a smaller household, want an oven that actually travels, or would rather put the price difference toward hardwood and a good pizza peel. Both make the identical 950°F, 60-second Neapolitan pizza — the only real question is how many people you’re feeding and how far you want to carry the oven to do it.
