Casket Sizing Guide: Standard and Oversized Dimensions

A standard adult casket is about 27½ to 30½ inches wide on the outside and 81 inches long, according to one online casket retailer. A second retailer says standard models suit people up to about 6'5" and 350 pounds. There is no legal standard, so sizes differ by maker, and the space inside is always smaller than the outside measurements.

If your loved one is broader or taller than that, oversized caskets are sold in widths from about 27½ to 44 inches. The size of the casket then affects the vault and the grave, so it pays to check with the cemetery before you buy.

What are the standard dimensions of a casket?

Sellers publish their own numbers, and they are close but not identical:

• Overnight Caskets says the most common exterior size is about 24 inches high, 27½ to 30½ inches wide and 81 inches long.
• Titan Casket lists oversized models with an exterior length of 83 inches and a height of 23 inches, with width as the only thing that changes.

Treat these as typical, not guaranteed. Always ask the funeral home or seller for the exact exterior and interior measurements of the model you are looking at. Caskets with thick walls or padded linings can leave less room inside than the outside suggests.

Interior and exterior measurements: which one matters?

Both matter, for different reasons.

• Exterior size decides whether the casket fits in the hearse, the outer burial container (vault) and the grave.
• Interior size decides whether your loved one fits comfortably. It is smaller than the exterior because of the walls, the bed and the lining.

When you compare two caskets with the same outside width, ask which one has more usable space inside.

Who needs an oversized casket?

One retailer's figure of about 6'5" and 350 pounds is a rough guide, not a rule. A person can be under the weight figure and still need a wider casket because of shoulder or hip width, or be lighter but very tall.

The funeral home can take measurements and tell you whether a standard casket will work. If you are close to the limits, ask for the next size up rather than hoping it fits. If your loved one is taller than a standard casket allows, ask about extra-length or made-to-order models and how long they take to arrive.

Also ask whether the funeral home keeps oversized models in stock. Many sellers ship on order, so the sooner you ask, the less rushed the choice will be.

Oversized casket widths and prices

Oversized models come in steps. Titan Casket lists widths of 28, 29, 33, 36, 40 and 44 inches, and Overnight Caskets lists 27½, 28½, 30½ and 31 inch models plus a wide-capacity line from 32 to 44 inches. These are retailer listings seen in September 2026, and prices change, so treat them as a snapshot.

Funeral homes price oversized caskets on their own casket price lists, so get those too. The FTC Funeral Rule says you must be shown a written casket price list before you see the actual caskets.

How vaults and cemetery rules affect casket size

Nothing in federal law requires a burial vault or grave liner, and in most areas state or local law does not require one either. Many cemeteries do require an outer burial container so the grave does not sink, which is a cemetery rule, not a legal one. The FTC says funeral providers must say so honestly.

For casket size, this means two questions for the cemetery:

1. Do you require an outer burial container, and what is the widest one you can place in this section?
2. Is the grave space wide enough, or would a wider space cost more?

Titan Casket notes that its 28 and 29 inch oversized models fit standard vaults, which suggests wider models may not. Ask the cemetery for its limits in writing if you can. Our guide to burial vaults explained covers the container itself, and cemetery rules and regulations explains what cemeteries can ask for.

Buying a casket somewhere other than the funeral home

The FTC says a funeral provider cannot refuse to handle a casket you bought online, at a local casket store or elsewhere, or charge you a fee to do it. A funeral home can still include its basic services fee in the price of its own caskets, and that fee applies if you bring your own.

Before you order, tell the funeral home the delivery date and ask who will receive the casket. The guides on buying a casket online and bringing your own casket walk through the steps.

What if your loved one will be cremated?

No law requires a casket for cremation. The Cremation Association of North America (CANA) says the container must be completely enclosed, rigid, leak resistant and combustible, and metal caskets are not accepted. The funeral home must offer alternative containers, such as unfinished wood or cardboard.

If the person is larger than average, ask the crematory directly whether it can accept the size and weight of the container you plan to use. Equipment differs from one crematory to another. CANA reports that 62.8% of people in the US were cremated in 2025. See cardboard caskets and types of caskets for options.

Claims that do not hold up

Some sellers talk about caskets that "protect" or "preserve." Under the FTC Funeral Rule, a provider cannot claim that any goods will delay natural decomposition for a long or indefinite time. A sealed casket can cost more, but you should not buy it expecting it to preserve a body.

What to do next

1. Ask the funeral home to measure your loved one and tell you what size range fits, including the interior width.
2. Ask the cemetery about outer container rules, the maximum vault width and any charge for a wider space.
3. Get the funeral home's casket price list, then compare it with outside sellers if you want to.
4. Confirm the delivery date in writing before you order an oversized or made-to-order casket.
