CHOOSING THE RIGHT LADDER FOR THE JOB
STEPLADDERS
To ensure you choose the ladder best suited 
to your needs, follow the Werner height 
safety charts. 
The highest permitted standing level on a step 
ladder is two steps down from the top. A person 
standing higher may lose their balance and fall. 
A person’s maximum safe reaching height is 
approximately 4’ higher than the height of the 
ladder. For example, a typical person can safely 
reach an 8’ ceiling on a 4’ ladder*.
EXTENSION LADDERS
Extension ladders should be 7 to 10 feet longer 
than the highest support or contact point, which 
may be the wall or roof line. This will allow 
enough length for proper setup, the overlap of 
ladder sections, height restrictions of the highest 
standing level, and where appropriate, the 
extension of the ladder above the roof line. The 
highest standing level is four rungs down from 
the top.
