Bariatric Casket Sizes — Oversized Options, Vault Requirements, and Plot Costs
When a larger-bodied person dies, the family faces a sizing problem that funeral homes often handle poorly — either by not mentioning the issue until the last moment or by steering families toward the most expensive options without explaining the alternatives.
The Sizing Threshold
Standard adult caskets (84 × 28 × 23 inches, interior width 23–24 inches) accommodate individuals up to about 350 pounds. Beyond that weight — or if the funeral home's measurements show the standard interior will not accommodate the person — an oversized casket may be needed.
The industry uses the term "bariatric" for caskets designed for individuals over 500 pounds, though the oversized range starts lower:
| Width | Interior Width | Weight Capacity | Vault Requirement |
|---|---|---|---|
| 28" oversize | 27.75" | Up to 450 lbs | Standard 30" vault |
| 29" oversize | 28.75" | Up to 500 lbs | Standard 30" vault |
| 33" oversize | 32.75" | 500+ lbs | Oversized vault |
| 36" oversize | 35.75" | 500+ lbs | Oversized vault + double plot |
| 44" oversize | 43.75" | 500+ lbs | Oversized vault + double plot |
The Cost Cascade
The casket itself costs more — an oversized steel casket runs $1,500 to $4,000+, compared to $825 to $3,400 for standard sizes.
But the real expense is the domino effect triggered by caskets 33 inches or wider:
Oversized burial vault. A standard vault's 30-inch interior can't hold a 33-inch casket. Oversized vaults cost $500 to $2,000 more than standard models and may need to be special-ordered.
Second cemetery plot. Caskets 36 inches and wider don't fit in a standard single plot (36 inches wide). The cemetery may require purchasing an adjacent plot, which can double the plot cost — adding $1,000 to $5,000+ depending on location.
Equipment. Not every funeral home has equipment rated for heavier-duty lowering. Some may charge additional fees for specialized transportation or lowering devices.
Total additional cost for a bariatric burial can reach $3,000 to $8,000 above what a standard-size burial would cost.
How to Get the Right Size
The funeral home should take body measurements, but it helps to know the person's approximate weight and build:
- Under 350 lbs and within the standard casket's measured interior — standard casket
- 350–500 lbs — 28" or 29" oversize (critical advantage: these still fit a standard vault and single plot)
- Over 500 lbs, or if measurements show a 28- or 29-inch model will not fit — 33"+ (triggers vault upgrade and possibly a second plot)
When in doubt, go one size up. The 28" and 29" oversize models cost modestly more than standard but avoid the vault-and-plot cascade entirely. This is the most important call to get right.

Ordering and Delivery
Oversized caskets are not always in stock at funeral homes. Online retailers like Titan Casket and Trusted Caskets carry bariatric models with two-to-seven-day shipping. The FTC Funeral Rule protects your right to buy from any source — the funeral home cannot charge a handling fee or refuse to accept a third-party oversized casket.
Confirm with the cemetery before ordering:
- What is the maximum casket width for a single plot?
- Do you have oversized vaults in stock, or is a lead time needed?
- Is a second adjacent plot available if needed for 36"+ caskets?
Cremation as an Alternative
For families who find the cost cascade prohibitive, cremation bypasses the oversized casket, vault, and double-plot issue entirely. Choose an urn based on the person's pre-cremation weight, using the one-cubic-inch-per-pound sizing rule.
The Casket & Urn Selection Guide includes the full oversized casket chart, a casket sizing worksheet, and a cemetery compatibility checklist — so you can navigate this process with the right information before the funeral home presents its options.
