Is the maximum extended length of an extension ladder the same as its size?

The maximum extended length of an extension ladder is not the same as its size because "size" typically refers to the ladder's nominal height or specific classification rather than its fully extendable length. A ladder's size is often defined by its rung count or the height it is rated for, which may be less than its maximum extended length.

Additionally, ladder specifications indicate a maximum height for safety and usability, while the maximum extended length reflects how far it can reach when fully extended. This distinction is crucial because it affects how the ladder can be used safely and effectively. Therefore, understanding that the maximum extended length can exceed the size helps ensure proper usage and adherence to safety guidelines during ladder use.
