A pet marker is usually the first memorial anyone buys. There is no funeral director walking you through options, no cemetery handing you a specification sheet, and very little published guidance. Most people start by searching for a size and find a dozen different answers.
This guide sets out the sizes actually in use, what each one suits, and the rules that vary by cemetery. It also explains, plainly, where our own marker fits and where it does not.
Common Pet Marker Sizes
Pet markers cluster around a handful of sizes. These are the ones you will see repeatedly from engravers and pet cemeteries in the US.
| Size | Typically used for |
|---|---|
| 6x12in | Cats, rabbits, small dogs. The most common size sold. |
| 8x16in | Small to medium dogs. Room for a name, dates, and a short line. |
| 10x14in or 10x16in | Medium dogs. Comfortable for a name, dates, and a small symbol. |
| 12x18in | Large dogs, or a longer inscription. |
| 12x24in or 14x24in | Large breeds, or two animals sharing one stone. |
Above roughly 12x24in you are usually into a double plot, a private garden, or a memorial that holds several pets at once.
Matching Size to the Animal
Size is not really about the animal. It is about how much you want to say. A 6x12in stone holds a name and two dates comfortably. Add a line of verse and it starts to feel crowded, because letters have to shrink to fit and small letters weather faster.
A rough guide: allow about 2 inches of height for a name, another 1.5 inches for dates, and 1 inch per line of any inscription, plus a margin of an inch or so on every edge. Work backwards from what you want engraved rather than forwards from the animal's size, and you will rarely regret the result.
The mistake families most often report is going too small. A marker that looked reasonable on a screen can seem lost in the ground once grass grows around it.
Cemetery Rules vs a Garden Memorial
Human cemeteries operate under state regulation and publish written specifications. Pet cemeteries do not. There is no state authority setting pet marker rules, so each cemetery decides its own limits on size, thickness, material, and whether markers must sit flush with the ground.
Many pet cemeteries cap a single plot at around 12x24in. Some are stricter. Some have no written rule at all and decide case by case. The only reliable approach is to ask for the limit in writing before you order anything, exactly as you would for a human plot. Our guide to cemetery headstone rules covers the questions worth asking.
A memorial placed in a private garden is a different situation entirely. There is no size limit, no approval process, and no installation specification. That freedom is why a large share of pet memorials never go into a cemetery at all.
Why Thickness Matters More Than Width
Pet markers are often sold at 1 inch thick, sometimes 2. Thin stone is cheaper to cut and cheaper to ship, and for a marker sitting on a shelf indoors it is perfectly adequate.
Outdoors it is a different question. A thin slab is more likely to crack under a mower strike, more likely to shift with frost heave in a cold winter, and more likely to break in transit before it ever reaches you. Thickness is the single specification most closely tied to how long a flat marker survives, and it is the one most often left out of a product listing.
Our own markers are 3 inches thick for exactly this reason. We wrote about the trade-off in detail in 3-inch vs 4-inch thick headstones.
One Stone for More Than One Pet
This is the case nobody plans for and many families arrive at. Over fifteen or twenty years a household loves several animals. Each loss brings a small marker, and eventually there is a row of mismatched stones in different sizes and materials, bought years apart from different sellers.
A single larger marker holding two or three names, with a shared design and room to add another later, avoids that. It reads as one family rather than a series of separate events, and it costs less than buying several small stones over time.
It also solves a practical problem. A small marker bought in 2015 from a seller who no longer exists cannot be matched. One stone with space left on it can.
What We Make, and What We Do Not
We make one size: a 28x16x3in flat granite marker. We do not make 6x12in or 8x16in pet markers, and we would rather say so here than have you find out after ordering.
That means a 28x16x3in marker is the wrong choice if you need a small stone for a cat in a cemetery with a 6x12in limit. Buy from an engraver who makes that size.
It is a good fit in three situations:
- A large breed. A Great Dane, Mastiff, Shepherd or similar sits comfortably with a 28x16x3in marker, where a 10x14in stone can look undersized.
- More than one pet on one stone. There is room for several names, dates, and a shared design, with space left to add another later.
- A private garden memorial. No cemetery limit applies, so the only constraint is what looks right in the space.
Everything else is the same as our human memorials: granite we quarry ourselves in the Himalayan mountains of Pakistan, engraving by sandblasting with stencils, a digital proof for your approval before any engraving begins, and free insured delivery to all 48 contiguous states. Prices start at $599 with engraving included.
Granite vs the Cheaper Alternatives
Pet markers are sold in materials that would never be used for a human grave, because the price expectation is lower. It is worth knowing what you are choosing between.
| Material | How it holds up outdoors |
|---|---|
| Granite | Resists frost, rain and UV. Sandblasted lettering stays legible for decades. |
| Marble | Softer stone. Acid rain gradually erodes the surface and shallow lettering fades. |
| Slate | Splits along natural layers over time, particularly with freeze-thaw cycles. |
| Concrete or resin | Cheapest option. Prone to cracking and surface loss within a few years outdoors. |
| Printed or painted plaques | The image sits on the surface rather than in it, so sunlight fades it. Often unreadable in three to five years. |
The distinction that matters is whether the lettering is cut into the stone or applied on top of it. Anything applied to the surface will eventually come off. Sandblasted granite is the same method used for human memorials expected to last a century.
Frequently Asked Questions
What size is a pet headstone?
Most fall between 6x12in and 12x24in. A 6x12in marker suits cats and small dogs, 8x16in suits small to medium dogs, 10x16in suits medium dogs, and 12x18in or larger suits big breeds. Pet cemeteries commonly cap a single plot around 12x24in, but every cemetery sets its own rule.
Do pet cemeteries have size rules?
Yes, though they are not standardized. No state regulates pet cemetery markers, so each one sets its own limits on size, thickness and material. Confirm the rule in writing before ordering. A memorial in a private garden has no size limit at all.
How thick should a pet grave marker be?
Many are 1 to 2 inches. Thicker granite resists cracking, frost heave and mower strikes better, which matters for anything left outdoors for decades. Ours are 3 inches.
Can one headstone hold more than one pet?
Yes, and it is often the better choice for a household that has loved several animals. A larger flat marker carries two or three names, dates and a shared design, with room to add another later.
Does SilkStone Memorial make pet headstones?
We make one size, a 28x16x3in flat granite marker. It suits large breeds, memorials holding more than one pet, and garden memorials with no size limit. It is not the right choice for a small cat marker in a cemetery with a 6x12in limit, and we would say so rather than sell you the wrong thing.
