Sectional garage doors are commonly designed with panels that typically range in height from 18 inches to 24 inches. The average height for these panels is often around 18 inches, making this dimension standard for most manufacturers. This height allows for efficient operation and a suitable aesthetic appearance, ensuring that the door can move smoothly when opened or closed without being overly cumbersome.

Options that suggest dimensions smaller than 18 inches, such as 12 inches, may not provide enough vertical panel space to achieve a functional garage door. Similarly, taller dimensions like 24 inches or 30 inches, while they can be found in specific designs or custom applications, are not as routinely used for standard sectional garage doors. Thus, the choice of 18 inches reflects the common industry standard, balancing practicality with usability.
