300 in² of Patented Oval Two-Zone Cooking — The Primo Sweet Spot
The Primo Oval Large 300 is the mid-size oval kamado — more cooking room than the Junior, more manageable footprint than the XL 400, with the same patented two-zone firebox and full 180–850°F range built into both.
At 300 square inches, the Oval Large gives you room for a family meal without the commitment of a 250 lb. grill. The patented oval firebox runs direct and indirect zones simultaneously — sear on one side while something low-and-slow holds on the other — and the SuperCeramic walls lock in heat efficiently enough that the full 180–850°F range is available with minimal charcoal. Reversible split stainless steel grates handle different cooking heights, the 6-position chimney cap and 5-position lower vent give you precise airflow in any weather, and the lift-and-lock hinge drops lid effort by up to 70%. Made in Georgia since 1996, backed by Primo's Limited Lifetime Warranty on ceramic parts, and built to cook as well in a decade as it does on day one.

Who It's For — The Deck & Den Take►
The Oval Large 300 is the Primo for most people. It hits the size range where a family meal fits comfortably without the grill overwhelming a typical backyard patio or deck. At 152 lbs. and 24" × 18.5", it's meaningfully lighter and more compact than the XL 400 while still running the patented two-zone firebox that makes the oval design genuinely useful.
If you regularly cook for larger groups or want to run very large briskets and whole birds side by side, step up to the XL 400. If your primary outdoor cooking is for two to four people with occasional larger meals, the Large 300 is probably the more honest fit — and easier to manage long-term.
The source doesn't specify what expanded cooking surface the optional extension racks reach, so confirm that with us if you're planning to add racks from day one. Otherwise, 300 in² is well-suited to everything from weeknight searing to weekend smoking sessions.
- Families who want a full-featured oval kamado that fits a standard backyard patio without dominating it
- Cooks who want true simultaneous two-zone cooking — the patented oval firebox delivers this without accessories or workarounds
- Buyers upgrading from a kettle, gas grill, or entry-level kamado to a lifetime-warranted American-made ceramic cooker
- Anyone who wants the full 180–850°F range for smoking, roasting, baking, and searing on one grill
