Quick answer
Yes, if your kamado is a small one (33 cm grate: MiniMax, Joe Jr, Monolith Icon), you want individual pizzas and you measure first. It is a round enamelled stoneware stone, 26 cm and 1.18 kg, rated 4.4 out of 5 on 572 reviews. But Weber lists it for charcoal from Ø 37 cm, the listing contradicts itself on thickness and gives no maximum temperature.
Enamelled stoneware, 26 cm across, 1.18 kg. On a 33 cm grate it leaves about 3.5 cm a side, but Weber lists it for charcoal from Ø 37 cm and never names kamados: measure first.
The Weber 18413 is a round baking stone 26 cm across, 1.18 kg, black, in stoneware ceramic with an enamelled finish. The listing presents it for pizza, bread and desserts, and Weber itself makes it (model 18413). It is one of a range of three: this one, another round at 36 cm and a rectangular 30 × 44 cm.
The first thing to know is that the listing does not agree with its own measurements. The title and the overview say 26 × 26 × 2 cm; the details table says 27 × 27 × 4 cm. The diameter hardly changes, but the thickness doubles, and in a small kamado every centimetre counts in the gap between the pizza and the dome. Weber also advertises it for charcoal barbecues "from Ø 37 cm". A 33 cm kamado falls below that minimum, and the listing neither explains what it is based on nor mentions kamados. So the fit is worked out from grate diameter, with a "check your own measurement" up front, and it is your call, not a Weber recommendation.
By diameter, it makes sense in the catalogue's small kamados. On a 33 cm grate (Big Green Egg MiniMax, Kamado Joe Joe Jr, Monolith Icon) there is about 3.5 cm to spare a side; on the BBQ-Toro Haiiro 32, if its grate measures the 32 cm in the name, about 3. On the Landmann Mini 27 it is borderline: half a centimetre a side at 26 cm, and none if the stone measures the 27 cm in the table. On a 46 cm Large or Classic it fits easily but is too small: there a bigger one pays off, such as the Rösle VARIO 30 cm or the Lithos Materie 30 × 30 cm Etna lava slab, whose diagonal is about 42 cm (a calculation).
In practice, that means individual pizzas of about 22-23 cm (an estimate), one at a time. The text for the range suggests putting it directly over the heat source; in a kamado the usual reasoning is different: stone on the grate with a deflector beneath, cooking indirect so the base does not scorch. The guide to pizza in a kamado explains the set-up, and the marinara is the simplest recipe to christen it with. Against the Rösle VARIO 30 cm, which is unenamelled cordierite, this one is 4 cm smaller and enamelled.
The drawbacks, read off the listing: it publishes no maximum temperature or thermal-shock resistance, two key figures for a stone that will work at pizza temperature inside ceramic. It is hand wash only and says nothing about soap or soaking. The seller's bullets are empty ("baking stone", "optimum quality product"). And it is not the Weber 8836 Gourmet, which is a different system with a tray, nor the rectangular 44 × 30 cm in the same range.
A score without hands-on testing: it comes from the listing, its geometry and its fit with the catalogue's small kamados. Verdict: a well-rated stone from a known brand for individual pizzas in 33 cm kamados, provided you measure first and accept going below the minimum Weber states.
A 26 cm Weber stone rated 4.4 out of 5 that fits 33 cm kamados by diameter. Measure first: Weber lists it from 37 cm and the listing contradicts itself on thickness.
Editorial rating from spec sheet, measurements and kamado fit · not a hands-on test
Pros
- Round, 26 cm and 1.18 kg: about 3.5 cm to spare a side on a 33 cm grate
- Stoneware with an enamelled finish that, per the listing, helps stop sticking
- Made by Weber (model 18413), rated 4.4 out of 5 on 572 Amazon reviews
- Per the listing, it also handles bread and desserts, not just pizza
Cons
- The listing gives 26 × 26 × 2 cm and also 27 × 27 × 4 cm: thickness contradicts itself
- Weber lists it for charcoal from Ø 37 cm: a 33 cm kamado falls below that
- No maximum temperature or thermal-shock figure; hand wash only
Who it's for
For anyone with a small kamado (MiniMax, Joe Jr, Icon) who wants individual pizzas without buying a separate oven and cooks for one or two.
Not for
If your kamado is 46 cm or larger, it is too small. Nor if you want big pizzas, need the maximum temperature in writing or would rather respect Weber's minimum.

G.a HOMEFAVOR Perforated Aluminium Pizza Peel 22.8 cm
A perforated peel of 22.8 cm according to its title, a sensible width for loading the roughly 22-23 cm pizza this stone takes. A peel of 30 cm or more is harder to handle on a 26 cm surface. It has not been tested here; it goes with the stone because without a peel there is no clean way to load it.

Kesper 58462: 32 cm round bamboo pizza board with cutter
A round 32 cm bamboo board with a cutter, for taking the pizza off the stone and cutting it without chilling it on a plate. With 22-23 cm pizzas the board leaves plenty of margin (a calculation, not a test). It has not been tested here; it is a serving extra, not a cooking one.

Weber 17896 – Premium Leather Gloves for Embers and Hot Grates
A 1.18 kg stone at oven temperature cannot be moved with a bare hand or a tea towel. Weber's leather gloves, from the same brand, protect you when placing it on the grate and taking it off with the kamado hot. They are bought as a safety extra, not as part of the recipe.

FAQ
Will it fit my 33 cm kamado?
By diameter, yes: 26 cm on a 33 cm grate leaves about 3.5 cm a side. That is the case for the MiniMax, the Joe Jr and the Monolith Icon. But Weber lists it for charcoal barbecues from 37 cm, without naming kamados, so 33 cm falls below its minimum, and the listing gives two thicknesses (2 and 4 cm). Before ordering, measure your grate diameter and the gap between it and the lid with the deflector in place.
How does it differ from the 30 cm Rösle and the Weber 8836?
The catalogue's Rösle VARIO 30 cm is cordierite, unenamelled, and 4 cm wider. This Weber is enamelled stoneware and smaller, meant for 33 cm kamados. The Weber 8836 Gourmet is a different system: it comes with a tray and slots into Weber's GBS system. If all you want is a loose stone for a small kamado, this is the comparable one; for a 46 cm kamado, the Rösle or an even bigger stone is the better fit. Another single-pizza route in a 33 cm kamado is the Victoria 25 cm cast-iron pan with handles: pan pizza, with a base browned by contact instead of a stone; add the handles when measuring the gap (an estimate).
Can it sit directly on the coals?
Weber's text talks about placing it directly over the barbecue's heat source, but says nothing about kamados or thermal shock. As a matter of physics, a thick stone resting on a coal bed stores heat from below and can scorch the base before the cheese has melted. The usual kamado set-up is stone on the grate with a deflector beneath, warmed slowly with the lid closed rather than subjected to a sudden change.
How do you clean the enamel?
The listing says hand wash and states that the enamelled finish helps stop food sticking and makes cleaning easier. It publishes nothing more: not whether soap is fine, not whether it can be soaked, not how many heat cycles the enamel survives. The prudent route is to let it cool completely, scrape dry residue off with a plastic spatula and wipe with a damp cloth, without submerging it or washing it hot.
