Companion Headstone: Costs, Design Options, and When to Order

What a Companion Headstone Is — and What It Isn't

A companion headstone is a single monument designed to memorialize two people, almost always a married couple or life partners who share a burial plot. One name and date set goes on the left, the other on the right, with a shared family name, a central motif, or a joint inscription across the top.

It's not two separate headstones placed side by side. A companion monument is one continuous stone — wider than a standard single marker — that spans the full width of a companion (double) or side-by-side plot. The structural base, foundation, and setting are engineered as a single unit.

The key distinction matters because cemetery rules, foundation requirements, and pricing all differ between a true companion monument and two individual markers placed on adjacent graves.

Companion Headstone Styles

Upright companion is the most common configuration. The stone typically measures 36–48 inches wide, 20–28 inches tall, and 6–8 inches thick, set on a granite base that extends several inches beyond the die (the main upright piece) on each side. The wider format provides room for individual inscriptions on each half, with a central area for a shared surname, wedding date, or design element.

Flat companion markers (also called lawn-level or flush markers) sit level with the ground. Standard dimensions run 36–44 inches wide by 12–14 inches deep. These are required in memorial park and lawn-level sections where mowing equipment must pass over the marker without obstruction.

Slant companion markers sit at an angle on a granite base, offering more visible inscription area than a flat marker while staying lower than a full upright. Width is similar to an upright companion — typically 36–42 inches.

Double-depth companion refers to the burial arrangement, not the marker style. In a double-depth plot, two caskets are stacked vertically in the same grave space. The headstone is a standard companion design but marks a single plot address rather than two side-by-side plots. Some cemeteries have specific foundation requirements for double-depth installations because the deeper excavation affects soil compaction differently.

Costs and What Drives Them

A companion headstone runs $2,000–$8,000 or more depending on material, size, and engraving complexity. The main cost factors:

Granite grade. Level 2 mid-grade granite (the standard commercial monument stone) costs less than Level 3 premium imports like Jet Black African, Royal Blue Pearl, or Mahogany Red. Premium granite delivers tighter grain and better contrast for laser-etched portraits, but the material cost is 40–80% higher than mid-grade.

Size. A 48×28-inch upright companion weighs 600–800 pounds before the base, requiring heavier transport equipment and a larger concrete foundation than a 36×24-inch stone. The base itself adds another 200–400 pounds. Foundation costs alone (concrete, excavation, setting) run $300–$600 for a companion monument versus $150–$300 for a single.

Engraving. Deep-cut sandblasting for lettering and simple designs is included in most base quotes. Laser-etched portraits ($200–$500 per portrait), ceramic photo ovals ($150–$400 each), custom relief carvings, and bronze accessories all add to the total.

The second name. One of the biggest cost advantages of a companion stone is that the base monument is a one-time purchase. When the surviving spouse dies, only the second name, final date, and any additional inscription need to be engraved — typically $300–$800, not the $2,000–$5,000 cost of a second standalone monument.

Ordering Timeline: Before or After the First Death?

Many couples order their companion headstone while both are alive. Pre-need ordering has real advantages:

• You make the design decisions together, while both of you can contribute to the inscription, symbols, and overall aesthetic
• You lock in pricing — granite and fabrication costs rise 3–5% annually
• The monument can be installed on the plot immediately (if the cemetery allows pre-need installations), with the surviving spouse's death date left blank
• You remove the burden from your family during grief, when cognitive impairment and decision fatigue make permanent choices harder

If the stone is ordered after the first death, the surviving spouse (or the registered deed holder) typically waits 4–6 months for the grave soil to settle before installing the foundation. The monument is fabricated with one complete name/date set and the other side prepared for future engraving — the surviving spouse's name and birth year are sometimes engraved in advance, with the final date left for later.

Cemetery Rules for Companion Monuments

Before ordering, get the cemetery's written rules for the specific section where your plot is located. Key questions:

• Does the section allow upright monuments? Many memorial gardens and lawn-level sections restrict markers to flush or slant styles only.
• What are the maximum dimensions? Companion monuments require wider footprints than singles — confirm the cemetery's width limit for your section. Some sections allow 36-inch maximum width, which is tight for a companion stone.
• Foundation specifications? Ask for the required foundation depth, width overhang beyond the die, and whether the cemetery pours the foundation or allows independent contractors. Foundation depth requirements vary — some northern municipalities require 36 inches to clear the frost line.
• Is pre-need installation allowed? Some cemeteries won't install a monument until the first burial occurs in the plot.
• What's the policy on second-name engraving? Confirm that the cemetery allows on-site engraving after the second death (most do, but a few require the stone to be temporarily removed for shop work).

Get everything in writing. Verbal assurances from a cemetery sales representative don't bind the administration that will review your permit application.

Common Mistakes With Companion Headstones

Ordering too narrow. A 36-inch companion stone looks cramped once two full name sets, dates, and inscriptions are engraved. Unless the cemetery restricts width, consider 42–48 inches for comfortable spacing and room for a central motif.

Ignoring the foundation. A companion monument is significantly heavier than a single. On a newly dug grave, the disturbed soil needs 4–6 months to compact naturally. Installing too early risks tilting or uneven sinking — a problem that costs $500–$1,500 to correct by re-leveling and re-setting the foundation.

Not coordinating the inscription. When the first spouse dies and the family orders the stone, the surviving spouse may not be involved in the design — grief, logistics, and adult children making decisions independently can all contribute. Make sure the second-side inscription is agreed on while the surviving spouse can participate.

The Headstone, Gravestone & Memorial Marker Guide includes a design planning checklist that walks through every dimension, material, and inscription decision for both single and companion monuments — with a vendor comparison worksheet so you can evaluate quotes from multiple monument builders on equal terms.
