For a 16' step ladder the standing height is 13.5'. Can I assume this is not the very top step, but instead is 2 or three steps down for safety where you can still hold the ladder with your hand? More specifically, what is the standing height (where my feet are) when I am standing on the 3rd step from the top. So I am standing on the 3rd step. There is a 2nd step and then the very top of the ladder is the TOP (1st) step.

You don't want to ever stand on the top of ladder.

Answers

Answer: 
The reach height is determined by using the average person's height and arm length without over reaching while on the ladder. To determine the reach height, it is assumed the person is 5'6" with a 12" vertical reach.

Answers

Answer: 
Usually the fiberglass ladders are heavier than the aluminum ladders. This does not hold true for all comparable fiberglass and aluminum ladders. The 412 aluminum step ladder weighs 54.5 while the 7412 fiberglass ladder weighs 49.5 pounds.

Different types of ladders are designed to keep you safe and productive when climbing or standing. Using the wrong style of ladder or simply ignoring the limitations of climbing equipment can result in a fall or serious injury.
Height is referring to the actual ladder height. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. The highest standing level is four rungs down from the top. The highest permitted standing level on a stepladder is two steps down from the top.

Reach height is the maximum reach assuming a 5’6” person with a vertical 12” reach.
Ladders are designed to safely hold up to a specific amount of weight. The Werner Performance System defines five different capacities using a color and star rating system. The Duty Rating is defined as the maximum safe load capacity of the ladder. A person’s fully clothed weight plus the weight of any tools and materials that are carried onto the ladder must be less than the load capacity.

Werner offers ladder made from fiberglass and aluminum. Each material has characteristics which make it best for certain applications, or one material may simply fit the personal preferences of the user. For example, if working around electricity users should select fiberglass products due to their non-conductive side rails.
