How much do extra sizes of caskets increase for each additional width?

The increase in size for caskets as they go to an extra width typically follows a consistent measurement that is standard within the industry. In this case, each additional width tends to increase by 2 inches. This size increase accounts for the overall proportional expansion needed to maintain comfort and dignity, allowing for varying body sizes while ensuring the casket still fits appropriately in standard burial spaces or funeral settings.

Understanding this standard helps in both practical arrangements and in guiding families through the options that best suit their needs. The other options present different increments but do not align with the typical, standardized increment used in casket sizing, which is well-documented in industry practices.
