Casket Sizes Guide
Casket Sizes Guide
By Marcus Chen, Licensed Funeral Director · Reviewed for accuracy on manufacturer specifications
Marcus has worked in funeral service for 14 years and currently directs at a family-owned funeral home in Sacramento. He's overseen thousands of casket orders, including the sizing conversations that families often find most stressful — this guide reflects the questions he fields most often at the arrangement table.
Standard adult caskets measure about 79–84 inches long, 28 inches wide on the exterior, and 23 inches high, with an interior width of roughly 24 inches. This "standard size" fits the majority of adults comfortably, but funeral homes also stock oversized, youth, and infant caskets to match different body sizes. If you're planning a funeral or pre-arranging one, knowing these measurements ahead of time helps you order the right casket the first time, avoid delivery delays, and budget accurately. Below, we break down every size category, show you how to measure for a proper fit, and answer the questions families ask most often.
"I've had families order a casket based on weight alone, only to find out at delivery that the shoulders don't clear," Marcus notes. "It's an awful thing to deal with the day before a service. A five-minute measurement conversation prevents almost all of it."
If you're comparing options for yourself or a loved one, a licensed funeral director can confirm exact measurements before you order — but this guide gives you the working knowledge to ask the right questions. You can also compare listed prices by size on our casket pricing guide.

Standard Casket Dimensions
A standard adult casket is built to a fairly consistent industry template: about 79 to 84 inches in exterior length, 28 inches in exterior width, and 23 to 24 inches in height. The interior — the part that actually holds the body — is narrower, typically around 24 inches wide and 6 feet 2 inches to 6 feet 6 inches long. This standard size accommodates adults up to roughly 200 pounds and 6 feet 1 inch tall, though exact thresholds vary by manufacturer.
According to published specifications from Batesville Casket Company, one of the largest U.S. manufacturers, its standard 20-gauge steel line runs 79" L × 28" W × 23" H with a 24" interior width — the template most competitors size against. Matthews Aurora's standard wood and metal lines list nearly identical exterior dimensions, with interior clearance varying by a fraction of an inch depending on the model. Casket makers design to this shared template because it matches the standard burial vault and grave liner sizes used in most U.S. cemeteries, which keeps costs predictable and avoids last-minute sizing problems at the cemetery. For a full breakdown of how material choice affects price at each size, see our casket pricing guide.
Casket Width vs. Interior Width
Families often confuse a casket's exterior width (the outside measurement, including the molding and hardware) with its interior width (the actual space inside for the body). A casket listed as "28 inches" almost always refers to the exterior width. The interior width — what matters for fit — is usually 4 to 5 inches narrower. This distinction matters when a funeral home describes a casket as "standard" versus "oversized," since the difference is almost always in interior clearance, not the outer shell. Always ask the funeral director for the interior width and shoulder-to-shoulder clearance if size is a concern, rather than relying on the exterior dimension alone.
Size Comparison Table
The table below lines up typical exterior and interior dimensions across the four main casket categories, based on published manufacturer specifications and industry norms. Treat these as a starting reference — always confirm exact measurements for the specific model you're considering.
| Category | Exterior Length | Exterior Width | Height | Interior Width | Typical Fit |
|---|---|---|---|---|---|
| Standard adult | 79–84 in | 28 in | 23–24 in | ~24 in | Up to ~200 lbs, up to 6'1" |
| Oversized adult | 84–90 in | 29–40+ in | 24–26 in | 29–40 in | 200–500+ lbs, over 6'2" |
| Youth | 48–72 in | 20–26 in | 16–22 in | 16–22 in | Children through teenagers |
| Infant/stillborn | Under 24 in | 10–16 in | 8–12 in | 8–14 in | Newborns and infants |

Oversized Caskets
Oversized caskets — sometimes called "large," "extra-large," or "bariatric" caskets — are built for individuals who don't fit the standard interior width or length. These typically start at 29 inches interior width and go up in increments (29", 33", 36", 40", and beyond) to accommodate larger body sizes. Oversized caskets are also longer, often built for individuals over 6 feet 4 inches. Because oversized caskets require more material and sometimes reinforced handles and frames, they cost more than standard models — often several hundred to over a thousand dollars more, depending on the size jump and casket material. See current size-by-size pricing on our casket pricing guide.
When You Need an Oversized Casket
Funeral homes generally recommend an oversized casket when the individual weighed more than 200–250 pounds or measured over 6 feet 2 inches, though the right choice depends on actual body shape, not just weight or height alone. Shoulder width is often the deciding factor rather than overall body mass. "We keep a soft tape measure in the arrangement office specifically for this," Marcus says. "Nine times out of ten, families are relieved someone just asks the direct question instead of guessing." If there's any doubt, ask the funeral home to take actual measurements — most reputable providers will do this respectfully and confidentially before recommending a casket size. Ordering the correct oversized size upfront avoids the distress of a casket arriving that doesn't fit, which can delay a funeral service.
Child and Infant Casket Sizes
Caskets for children and infants come in a much wider range of sizes than adult caskets, since they need to match a child's actual size rather than a single standard template. Youth caskets typically run from about 48 to 72 inches in length, sized in steps to fit children and teenagers. Infant and stillborn caskets are considerably smaller, often under 24 inches, and some manufacturers and funeral homes provide these at reduced cost or at no charge, recognizing the financial strain such a loss brings. Full sizing detail and cost information is on our child and infant casket page. If you're arranging a service for a child, ask your funeral home directly about size options and any assistance programs — many hospitals and hospice organizations also keep infant caskets or burial gowns on hand for families facing this loss.
How to Determine the Right Casket Size
- Get the person's height and approximate weight. This gives the funeral home a starting point for recommending standard versus oversized.
- Ask the funeral director for shoulder width, if known, or estimate based on build. Shoulder width — not just height or weight — most often determines whether a standard casket will fit comfortably.
- Confirm interior dimensions, not just exterior. Ask specifically for interior width and length, since these are the numbers that determine fit.
- Check the cemetery's vault requirements. Some cemeteries require a specific outer burial container size; confirm the casket you choose is compatible before finalizing an order.
- Order with a size buffer if there's uncertainty. Funeral homes can often exchange an unopened casket for a different size before delivery, but this is far easier to arrange before the service than after.
- Ask about lead times for oversized or custom sizes. Standard caskets typically ship faster; oversized or custom sizes may take a few extra days depending on the manufacturer.

Casket Size vs. Burial Vault Size
A burial vault or grave liner is the outer container that holds the casket underground, and its interior dimensions must be larger than the casket's exterior dimensions to allow it to close properly. Standard vaults are built to fit standard caskets (around 28 inches wide), but an oversized casket requires an oversized vault to match — you cannot fit a 33-inch-wide casket into a vault sized for 28 inches. Many cemeteries require a vault or liner regardless of casket size, so if you're ordering an oversized casket, confirm with the cemetery that they carry or can order a matching oversized vault before the casket arrives. This is one of the most common scheduling delays families run into, and it's avoidable with a single phone call ahead of time. Our burial vault guide covers vault types, materials, and how sizing works in more depth.
The Federal Trade Commission's Funeral Rule requires funeral homes to provide an itemized price list, including casket options, which is a useful reference point when comparing sizes and costs across providers. You can review the rule directly at the FTC's consumer guide to funeral costs.
Wood vs. Metal Casket Dimensions
Wood and metal caskets are generally built to the same standard exterior dimensions (around 79–84 inches long, 28 inches wide), but construction differences can create small variations in interior space. Metal caskets typically have a consistent gauge-built shell with predictable interior clearance, while wood caskets — especially solid hardwood models — can have slightly thicker walls that reduce interior width by an inch or so compared to metal equivalents at the same exterior size. This rarely affects fit for standard-sized adults, but it's worth mentioning if you're on the borderline between a standard and oversized casket and comparing wood versus metal options. Our wood vs. metal casket comparison covers durability, cost, and appearance differences alongside these sizing notes. When in doubt, ask the funeral home for the specific interior measurement of the exact model you're considering, rather than assuming all "standard" caskets are interchangeable.
FAQ
What is the most common casket size? The most common casket size is the standard adult size: approximately 79–84 inches long, 28 inches wide (exterior), and 23–24 inches high, with an interior width around 24 inches. This size fits the majority of adults and is what most funeral homes stock in the highest quantity.
How do I know if I need an oversized casket? You likely need an oversized casket if the individual weighed more than roughly 200–250 pounds, stood taller than about 6 feet 2 inches, or had a broader shoulder width than average. Weight and height are useful starting points, but shoulder width is often the true determining factor — ask your funeral director to measure rather than estimate.
Do all cemeteries require a matching burial vault size? Most cemeteries require some form of outer burial container (a vault or grave liner), and its size must match or exceed the casket's exterior dimensions. If you order an oversized casket, confirm with the cemetery that an oversized vault is available before finalizing your order, since mismatched sizes can delay a service.
Are child and infant casket sizes standardized? No. Unlike adult caskets, child and infant caskets come in a wide range of sizes — often from under 24 inches for infants up to 72 inches for teenagers — because they need to match the individual child's actual size rather than a single template.
Does casket material affect the size I need? Not significantly. Wood and metal caskets are typically built to the same exterior dimensions, though wood models can have marginally less interior space due to thicker construction. If you're near the line between standard and oversized, ask for the exact interior measurement of the model you're considering.
