A grill is the hottest oven most people already own. The stone that works on it has to take a 700°F surface over a live flame without cracking, and a few do that much better than the rest.

The best pizza stone for a grill is the Weber Gourmet BBQ System Pizza Stone: a 16.7 inch cordierite round that ships with a carry rack, so you can lift a 500°F stone off the grate with gloves instead of leaving it to cool. It fits any grill, not just Weber's GBS grates. The best value is the Unicook 15 by 12 inch cordierite rectangle at about $29, the most-bought stone we track and a quarter-inch thicker than the Weber. If you want a full 16 inch round for the lowest price, Old Stone's 16 inch is the one.
What makes grill use different from oven use is thermal shock. In a kitchen oven the stone and the air heat together. On a grill the burners are inches below the stone and the lid vents above it, so the bottom can be 200°F hotter than the top. Cheap ceramic stones crack under that gradient; cordierite, the material every stone on this page is made from, is fired to tolerate it. The rule that prevents most cracks is simple: put the stone on a cold grill and heat them together, never drop a cold stone onto hot grates.

The short version
- Our Pick: Weber GBS Pizza Stone, 16.7 inches with a carry rack, about $60. The rack is the feature that makes grill use practical.
- Best value: Unicook 15 x 12 cordierite at about $29, 0.6 inch thick, and the stone that converts best across every Theory Road site.
- Rectangles use a grill grate better than rounds; a 15 x 12 stone fits a standard 3-burner gas grill with airflow on both sides.
- Heat the stone with the grill, lid down, burners on full for 20 to 30 minutes. Target 550 to 650°F on the surface; an infrared thermometer confirms it.
- Thermal shock, not heat, kills stones. Cold stone on a hot grate is the one thing never to do.

Our PickWeber Gourmet BBQ System Pizza Stone with Carry Rack (16.7 in)
A 16.7 inch cordierite round with a carry rack, from the grill maker, 4.6 stars across 2,200 owners.
On the bench: 16.7 inch cordierite stone with a steel carry rack; 4.6 stars across roughly 2,235 Amazon ratings on 2026-08-23.
The rack is the reason. The Weber GBS Pizza Stone sits in a steel frame with two handles, so you can set it onto a cold grill, heat it with the lid down, and lift it straight off when you are done. Every other stone on this page has to stay on the grate until it cools, which on a hot evening is an hour. At 16.7 inches it also bakes a true 16 inch pie.
At about $60 it costs twice the Unicook and does not publish a thickness on the listing. For a household that grills pizza monthly or more, the handling alone pays that back. For a first try, start with the value pick.
- Material
- Cordierite
- Size
- 16.7 in round
- Extras
- Steel carry rack
- Fit
- Any grill with 17 in clear span
- Price
- ~$60
What we like
- Carry rack solves hot-stone handling
- Largest round on the page
- Grill-maker design, 2,200+ owners at 4.6
Worth noting
- Twice the price of the value pick
- Round shape on a rectangular grate
Who should buy it: Regular grill-pizza cooks, Weber GBS grate owners, and anyone who has tried to move a hot stone without a rack.
What we don't like: Price. A round wastes grate space on a rectangular gas grill. Thickness not stated on the listing.
Bottom line: Weber's stone is the one built for the job rather than adapted to it. The carry rack means you lift the stone on and off the grate with gloves, which solves the real problem of grill pizza: what to do with a 550°F slab when the pizzas are done. It fits any grill with a 17 inch clear span, not just Weber's GBS grates, and it is the largest round here. The price is double the Unicook's.
02 · Alternative Rectangle with Scraper
Culinary Couture 15 x 12 in Pizza Stone
A 15 x 12 cordierite rectangle with a plastic scraper included, 1,100 owners at 4.4 stars.
On the bench: 15 x 12 inch cordierite for oven and grill, scraper included; 4.4 stars across about 1,105 Amazon ratings on 2026-08-23.
Same shape, a scraper, a few dollars less. The Culinary Couture 15 x 12 does what the Unicook does on a gas grill and adds a plastic scraper for baked-on cheese. The owner base is large enough to trust: about 1,100 ratings averaging 4.4.
A three-piece set with a peel is also listed for about $30 if you are starting from nothing.
- Material
- Cordierite
- Size
- 15 x 12 in
- Extras
- Scraper
- Price
- ~$25
What we like
- Large owner base at 4.4
- Scraper included
- Lowest price on the page
Worth noting
- Thickness not published
- No handles
Who should buy it: Buyers who want the rectangle format with a scraper, or find it on sale below the Unicook.
What we don't like: Thickness not stated. Plastic scraper is basic.
Bottom line: The Culinary Couture stone is the same footprint as the Unicook at a few dollars less, with a scraper in the box. Owners rate it 4.4 stars over more than a thousand reviews. The listing does not state thickness, which is why it sits below the Unicook's known 0.6 inch; if it is the one in stock or on sale, it is a fine buy.
03 · Best Value
Unicook 15 x 12 in Cordierite Pizza Stone
The best-selling cordierite rectangle, 0.6 inch thick, and the stone readers buy most.
On the bench: 15 x 12 inch cordierite, 0.6 inch thick, 6.8 pounds per the listing; 4.5 stars on the live Amazon page on 2026-08-23. The most-ordered stone across our sites.
The right shape for a gas grill. A 15 x 12 rectangle leaves a few inches of open grate on each side of a standard three-burner gas grill, which is what lets lid-down convection brown the top of the pizza while the stone browns the base. A 16 inch round on the same grill blocks most of that path. The Unicook's 0.6 inch thickness is also more than most budget stones offer, and thickness is what buys thermal-shock margin.
It is the most-purchased stone across every site Theory Road runs, and the owner average holds at 4.5 stars over years of listings. Its only real limit is handling: no rack, no edges to grab.
- Material
- Cordierite
- Size
- 15 x 12 in
- Thickness
- 0.6 in
- Weight
- 6.8 lb
- Price
- ~$29
What we like
- Rectangle fits a gas grill with airflow
- 0.6 in thick for the price
- Most-bought stone we track
Worth noting
- No handles or rack
- Plain, no extras
Who should buy it: Gas grill owners, first-time grill-pizza cooks, and anyone who wants the most stone for the least money.
What we don't like: No rack or handles. Needs to cool on the grill before it moves.
Bottom line: The Unicook is the stone most people should put on the grill first. It is cordierite, a generous 0.6 inch thick, and its 15 by 12 rectangle sits on a three-burner gas grill with air moving past both long sides. It has no rack and no handles, so it stays on the grate until it cools. At about $29 that is an easy trade.
04 · Best 16 in Round
Old Stone Round Pizza Stone, 16 in
A full 16 inch round at the value price, the natural fit for a 22 inch kettle.
On the bench: 16 inch round cordierite from Old Stone's listing; 4.4 stars on the live Amazon page on 2026-08-23.
Rounds belong on kettles. The Old Stone 16 inch round centers on a 22 inch Weber kettle with an even ring of open grate all the way around, which is exactly the airflow a lid-down charcoal bake wants. Bank the coals to the sides, set the stone on cold, and the convection does the rest.
Old Stone has sold this design for a long time and the owner average sits at 4.4 stars. It is the plain choice for a kettle; nothing fancy, nothing missing.
- Material
- Cordierite
- Size
- 16 in round
- Price
- ~$30
What we like
- Full 16 in surface
- Ideal shape for a 22 in kettle
- Value price
Worth noting
- No handles
- Wrong shape for gas grills
Who should buy it: Kettle-grill owners and anyone baking 16 inch pies.
What we don't like: No handles. Blocks airflow on a rectangular gas grill.
Bottom line: On a 22 inch kettle grill a round stone is the right shape, and the Old Stone 16 is the cheapest full-size round from an established maker. It bakes a 16 inch New York pie with margin and leaves a three inch ring of open grate around it for airflow. Like the Unicook it has no handles. On a rectangular gas grill, choose the Unicook instead.
05 · Best Starter Kit
Cuisinart 3-Piece Pizza Grilling Pack (13 in stone, peel, cutter)
A 13 inch stone, a folding peel, and a cutter from Cuisinart, for the cook starting from zero.
On the bench: 13 inch round stone, folding peel, and pizza cutter; 4.4 stars on the live Amazon listing on 2026-08-23.
Everything for the first pizza, in one box. The Cuisinart Pizza Grilling Pack pairs a 13 inch cordierite round with a folding peel and a cutter. The 13 inch size fits any grill including small two-burners, and it heats faster than the 16 inch stones above.
Owners rate the set 4.4 stars. The peel will eventually get replaced by a better one; the stone and cutter will last.
- Stone
- 13 in cordierite round
- Includes
- Folding peel, cutter
- Price
- ~$50
What we like
- Complete starter set
- Fits small grills
- Cuisinart brand support
Worth noting
- Small stone
- Basic peel
Who should buy it: First-time grill pizza cooks who own no gear, and small two-burner grill owners.
What we don't like: 13 inch stone limits pie size. The peel is entry-level.
Bottom line: If you own nothing yet, Cuisinart's three-piece pack is the tidy answer: a 13 inch stone sized for a 12 inch pie, a peel to launch it, and a wheel to cut it, for about $50. The stone is smaller than the others here, so it is the wrong buy for 16 inch pies, and the peel is basic. For a first season of grill pizza it is everything you need in one box.

How we chose
Grill stones are ranked on thermal-shock tolerance first (cordierite only; we excluded ceramic and glazed stones), then on handling (can you get a hot stone off the grill without a second person), then fit on a standard three-burner gas grill and a 22 inch kettle, then owner consensus on the live Amazon listing read on 2026-08-23, then price.
Every dimension is the listing's own figure. Where a listing does not state thickness we say so rather than guess.
Questions, answered
Can you use a pizza stone on a gas grill?
Yes, and it is the best use of one. Put the stone on the cold grate, close the lid, run all burners on high for 20 to 30 minutes, and bake with the lid down. Target 550 to 650°F on the stone surface, which an infrared thermometer confirms. Cordierite stones tolerate this; glazed ceramic ones often crack.
Why did my pizza stone crack on the grill?
Thermal shock. Either a cold stone went onto a hot grate, or a burner directly under one end heated it far faster than the rest. Heat the stone with the grill from cold, keep direct flame spread under the whole stone rather than one corner, and never wash a hot stone.
Round or rectangular stone for a grill?
Rectangular for a gas grill, because a 15 x 12 stone leaves open grate on both sides for lid-down airflow. Round for a 22 inch kettle, where a 16 inch round sits centered with an even ring of open grate. The Weber round with a rack is the exception that works on either.
How hot should a grill be for pizza on a stone?
550 to 650°F at the stone surface for New York style in five to seven minutes. Most gas grills top out around 600 to 700°F with the lid down, which is plenty. True Neapolitan needs 850°F-plus and a dedicated pizza oven.
Do you need a pizza stone or a steel for a grill?
A stone. Steel's speed is an advantage in a 550°F kitchen oven but a liability over a live flame, where it burns the bottom before the top sets. Save the steel for indoors; see our stone vs steel guide.
