Which Blackstone griddle should you buy?

For most households the answer is the Blackstone 28″ Original: 525 square inches, two independent zones and a 10-gauge rolled carbon-steel plate that is thicker than most griddles in its size class. Buy the 36″ if you regularly cook for more than six, the 28″ XL Omnivore if you want three zones on a normal patio, the 22″ if the griddle has to travel, and the 17″ only for camping.

The whole line on one table

Heat density is BTU per square inch of cooktop — the figure no manufacturer publishes and the one that predicts how fast the plate recovers when cold food lands on it. The arithmetic is here. Notice that it climbs with size across the whole line: the bigger Blackstones are not merely larger, they are better heated per square inch of plate.

*The asterisk matters. Read on.

Why the 28 is the default

525 square inches feeds a family of four with room to work, which at roughly 100 to 130 square inches per person is exactly where most households land — the sizing table shows the brackets. It fits a normal patio, it takes the most widely stocked cover size, and its plate is 10-gauge rolled carbon steel.

That last point is the underrated one. Thermal mass is what keeps the surface temperature from collapsing when eight cold patties go down, and the 28’s plate carries more of it than most griddles at this price. How much plate thickness really matters works through the numbers.

Its limitation is honest: two zones. You can sear on one side and hold on the other, and that is all. You cannot run a searing zone, a moderate zone and a holding zone at once.

When the 36 earns its footprint

769 square inches and four independently controlled zones is the griddle for cooking in waves for a crowd: eighteen to twenty patties per pass, or breakfast for eight without staging. At 78.0 BTU per square inch it also has the best recovery in the line.

The cost is not the price, it is the patio. A 36-inch cart does not get put away weekly; it occupies its space permanently, and that is the most common regret among owners of large griddles. Its grease system is also rear-mounted, which is awkward if the griddle lives against a wall.

Buy it because you genuinely cook for six or more. Do not buy it because the extra surface seems cheap — 28 vs 36 is the comparison most buyers actually need.

The 28 XL Omnivore: check the box first

On paper the 28″ XL is the most appealing griddle in the line — three zones and 613 square inches, the useful middle ground, on a footprint much closer to the 28 than the 36.

There is a catch. Retailers list the same 613-square-inch body at 28,500, 45,000 and 48,000 BTU depending on the variant. That puts its heat density anywhere between 46.5 and 78.3 BTU per square inch — from the weakest griddle on this site to a match for the 36. The surface area is settled; the output is not.

So the 28 XL is a conditional recommendation: excellent at 48,000 BTU, fine at 45,000, and worth skipping at 28,500. Read the figure off the exact listing in front of you. The full 36 vs 28 XL comparison shows all three cases.

The tabletops: 22 and 17

The 22″ is a genuinely useful small griddle — 339 square inches and two independently controlled zones, which is more control than most tabletops offer. It feeds two to three people and it fits in a car. Note that it is also listed at both 21,000 and 24,000 BTU, which moves its heat density between 61.9 and 70.8.

The 17″ is a camping griddle and should be bought as one: 267 square inches, a single burner, one temperature, 46.8 BTU per square inch, and it runs on 1 lb propane bottles. It is the right tool for a campsite and the wrong tool for a patio. Full review of the 17, and 17 vs 22 if you are between them.

What you take on with any of them

Every Blackstone here is bare carbon steel. That means three to five thin seasoning rounds before the first meal, oil after cooking, and a vented cover between cooks. Get that routine right and the surface becomes genuinely non-stick and can be restored from almost any state. Skip it and you will spend a season taking rust off.

What you get in exchange is the deepest parts and accessory ecosystem in the category. That does not matter on day one. It decides, in year four, whether a failed burner is a repair or a replacement.
