Blackstone 36 vs 28 XL
One of these griddles has a settled specification. The other has three, and the listing decides which you get.

Buy the Blackstone 36 Original for a settled specification and a fourth zone; buy the 28 XL Omnivore for three zones on a smaller footprint — but only after you have read the BTU figure off the exact listing, because the same 613-square-inch body is sold at three different outputs. The 36 is 769 square inches at 60,000 BTU, which is 78.0 BTU per square inch, every time. The 28 XL is 613 square inches at 28,500, 45,000 or 48,000 BTU depending on the variant.

Blackstone 28" XL Omnivore Griddle: Retailers list this body at 28,500 BTU (Academy), 45,000 BTU and 48,000 BTU — all at 613 sq in. The surface area is settled; the heat output is not. Check the BTU figure on the exact listing you are buying.
The variance is the headline, not a footnote
Retailers list the 28 XL Omnivore body at 28,500 BTU (Academy), 45,000 BTU and 48,000 BTU. The 613-square-inch surface is consistent across all of them. The heat output is not, and the spread is not small:
| Listed output | Surface | Heat density | Against the 36’s 78.0 |
|---|---|---|---|
| 28,500 BTU | 613 sq in | 46.5 BTU per sq in | 40% less heat per sq in |
| 45,000 BTU | 613 sq in | 73.4 BTU per sq in | 6% less |
| 48,000 BTU | 613 sq in | 78.3 BTU per sq in | Essentially identical |
At 48,000 BTU the 28 XL matches the 36 for recovery on a plate 20% smaller, which is a genuinely attractive griddle. At 28,500 it is one of the most lightly heated griddles on this site — below the Halo Elite 2B’s 50.0 — and would be a poor choice for anything involving a full load of cold food.
We publish the disagreement rather than picking a favorite number, which is our standing policy on conflicting listings. In practice it means one thing for you: find the BTU rating on the listing before you buy, not after.
Three zones against four
If the BTU figure checks out, the real comparison is zone count against footprint.
Three independently controlled zones is the useful middle. You can run a searing zone, a moderate cooking zone and a holding zone simultaneously, which covers nearly all household cooking including a full breakfast. The fourth zone on the 36 adds a dedicated toasting or warming lane on top of that — which matters when you are plating in waves for eight people and stops mattering entirely below about six.
The burner-count guide works through where the returns stop. The short version: the step from two to three zones changes how you cook; the step from three to four changes how many people you can cook for.
156 square inches, and the footprint that comes with them
769 against 613 square inches is a 25% larger plate — roughly five more patties per pass, or the difference between breakfast for six and breakfast for eight.
It also comes with a cart that is correspondingly larger, and the 36’s footprint is the most common regret among owners of large griddles. A 36-inch cart does not get put away weekly; it occupies its patio space permanently. The 28 XL is the version of this griddle that fits a normal patio and takes a more widely available cover size.
Two practicalities the spec sheets bury
Grease routing. The 36 Original uses rear grease management, which puts the drain and the cup behind the unit. Against a wall or in an alcove that is awkward in a way no listing warns you about, and it is the most common reason grease cups get left until they overflow. Check which way your griddle drains before you decide where it will live.
Covers and accessories. 36 inches is the most widely stocked size in the category, so covers, hoods and hard covers for it are easy to find from Blackstone and from a large third-party market. The 28 XL’s body is less universal, and because its published height is 59.44 inches, a cover sized for a standard 28 does not necessarily fit it. Match on width and hood, not on the model number — what to match on.
Fuel use follows the BTU rating directly: the 36 is about 0.66 gallons of propane an hour at full output against roughly 0.49 for a 45,000 BTU 28 XL. The per-model figures.
The Omnivore plate
The 28 XL ships with Blackstone’s Omnivore cooktop rather than the Original’s bare rolled carbon steel. Both are steel plates that season and both want a cover; the Omnivore plate is the newer design and is the subject of its own comparison in Original vs Omnivore. It does not change the seasoning routine, and it does not make either griddle rust-resistant.
If you do not need either
The third pick is the Blackstone 28 Original — 525 square inches, two zones, a 10-gauge rolled carbon-steel plate and a completely settled 34,000 BTU rating. It has less heat density than either griddle above (64.8) and no third zone, and it is the one with no specification ambiguity to check and the smallest patio cost.
Which to buy
| If you | Buy |
|---|---|
| Want a specification you can verify in advance | Blackstone 36 |
| Want three zones on a normal patio | Blackstone 28 XL (48,000 BTU variant) |
| Regularly cook for more than six | Blackstone 36 |
| Found only a 28,500 BTU 28 XL listing | Blackstone 36, or the 28 Original |
| Want the simplest, cheapest-to-cover option | Blackstone 28 Original |
| Care most about searing recovery | Blackstone 36 |

#1 · Large families and crowd cooking
Blackstone 36" Original Griddle
The default large griddle: four burners over 769 square inches, with the highest burner count in its size class and the deepest accessory ecosystem of any brand here.

Specifications from BBQGuys spec sheet.
Scores
- Cooking area9.5
- Heat output9.0
- Zone control9.5
- Surface care6.5
- Portability3.0
What works
- Four independent zones is the real argument for this size — you can hold a warm zone and still sear
- 769 sq in is enough to cook a full breakfast for eight without staging
- The widest accessory and spare-parts availability of any brand in this guide
What to know
- Bare carbon steel: it will rust if you leave it uncovered and unseasoned
- Needs real patio footprint — this is not a griddle you put away each week
- Rear grease management means the drain is behind the unit, which is awkward against a wall
#2 · Three zones without the 36's footprint
Blackstone 28" XL Omnivore Griddle
Three zones in a 613-square-inch body — the useful middle ground — but the BTU rating genuinely varies between variants, so read it off the listing in front of you.

Specifications from Academy Sports listing.
Listings disagree: Retailers list this body at 28,500 BTU (Academy), 45,000 BTU and 48,000 BTU — all at 613 sq in. The surface area is settled; the heat output is not. Check the BTU figure on the exact listing you are buying.
Scores
- Cooking area8.0
- Heat output7.5
- Zone control8.5
- Surface care6.5
- Portability4.0
What works
- Three zones at 613 sq in is the best zone-to-footprint ratio Blackstone sells
- Electronic ignition is more reliable over time than a piezo button
- Meaningfully more surface than the 28 without the 36's storage problem
What to know
- The BTU rating is not consistent across listings — the same 613 sq in body appears at 28,500, 45,000 and 48,000 BTU
- A 28,500 BTU example over 613 sq in is thin heat; that variant recovers slowly
- The Omnivore plate is a different surface from the classic carbon steel and takes seasoning differently
#3 · Most households
Blackstone 28" Original Griddle
The size most people should actually buy: 525 square inches and two zones covers a family of four with headroom, on a footprint that fits a normal patio.

Specifications from BBQGuys spec sheet.
Scores
- Cooking area7.5
- Heat output7.0
- Zone control7.0
- Surface care6.5
- Portability5.0
What works
- The 10-gauge plate is thicker than most griddles at this size, which is what keeps temperature steady when cold food hits it
- Two zones is genuinely enough: one hot side for searing, one moderate side for holding
- Fits a standard patio and a standard cover, which the 36 often does not
What to know
- Only two zones — you cannot run a dedicated warming zone and two cooking temperatures at once
- 34,000 BTU over 525 sq in is modest heat density; recovery after a big load is slower than the 36
- Bare carbon steel needs seasoning and a cover, same as every Blackstone
