Monument sizing follows industry conventions that have developed over decades of practical use. Understanding these standards helps you quote accurately, comply with cemetery requirements, and communicate clearly with your wholesale supplier. Sizing varies by monument type, and every measurement follows a specific order that you need to internalize.
For upright monuments, dimensions are stated as width × height × thickness, always in that order. The "die" is the upper portion that contains the inscription. A common single upright die might be 20×10×4 inches, meaning 20 inches wide, 10 inches tall, and 4 inches thick. A standard mid-size single runs 24×12×4, while a larger single might be 30×16×6. Double monuments (companion monuments) are wider: 36×12×4 or 42×14×6 are common examples. The "base" sits beneath the die and is stated separately: a 28×6×12 base means 28 inches wide, 6 inches tall, and 12 inches front-to-back (the depth). Note that base depth is often greater than die thickness to provide stability.
For flat grave markers, dimensions run length × width × thickness. A standard single flat marker is 24×12×4 inches. Cemetery-flush markers, required in many lawn-care cemeteries, are typically 24×12×3 or 24×12×4 with a beveled edge so lawn mowers can pass over without damage. Double flat markers are commonly 24×24×4 or 28×16×4. The thickness is critical — most cemeteries specify a minimum (usually 3 or 4 inches) to ensure the marker won't shift or crack under ground pressure.
Slant markers occupy a middle ground between flat and upright. They are set at an angle, usually between 15 and 45 degrees from horizontal. A common slant marker die face size is 20×10, meaning 20 inches wide and 10 inches on the slanted face. The back of a slant is shorter than the front, typically 4–5 inches, and the base is a separate piece. Slants are popular because they are visible from a standing position, easier to read than flat markers, yet lower-profile than uprights — making them suitable for cemeteries that restrict upright heights.
Bevel markers (sometimes called pillow markers) have a raised, curved top surface rather than a flat face. They typically run 24×12×4 with a beveled top face and are set slightly raised above grade, supported by a buried concrete foundation or pins.
Weight matters for logistics. A 24×12×4 die in black granite weighs roughly 80–90 pounds. A 28×6×12 base adds another 60–70 pounds. For large companion monuments with full bases, total weight can exceed 500 pounds, affecting shipping costs and setting requirements. Keeping a weight reference chart handy helps you estimate freight costs accurately when quoting clients.
Cemetery regulations often dictate which sizes are permitted. Always verify with the specific cemetery before finalizing a monument order. Some cemeteries provide a printed rule sheet; others require you to call the office directly. Getting size approval in writing protects you if there is ever a dispute about whether a monument meets regulations.
