For every job, there’s the right ladder.
This guide is designed to take you through the process of selecting the ideal ladder type, material, load capacity, and height to help you get job done right.
At Featherlite Ladders, all of our products are designed and constructed to meet or exceed applicable standards and requirements of the American National Standards Institute (ANSI), the Occupational Safety and Health Administration (OSHA), and the Canadian Standards Association (CSA).
Select A Material
The next step in selecting your perfect ladder is choosing the right material. Aluminum ladders are cost-effective, light-weight, and quick & easy to transport. Fiberglass ladders can be heavier, but they’re stronger, more durable, and absolutely required when working around electricity because of the material’s non-conductive properties.
- Long-lasting construction
- Resists corrosion
- Ideal for painting, roofing, and siding
Do not use aluminum ladders near electricity.
- Non-conductive when clean and dry
- Strong and durable
- Great for heavy-duty construction
Fiberglass ladders are required for working around electricity.
Select A Load Capacity
Featherlite Ladders are manufactured in compliance with the Canadian Standards Association (CSA) safety standards for portable ladders. The CSA standard has established a duty rating which identifies the use for which a portable ladder is intended and the conditions under which the ladder can be used safely. An extensive series of tests and design requirements determine which duty rating label a ladder may receive. The total load supported includes the combined weight of the user, clothing, tools, and any materials on the ladder; however, ladders must be used properly to support the intended load.

Select A Height
The last step in selecting your perfect ladder is choosing the right height. Selecting a ladder height appropriate for your task takes careful consideration. Use these charts below to determine if a particular ladder size will allow you the reach to get the job done.
Step Ladder Heights
When using a step ladder, the highest permitted standing level is two steps down from the top. Any higher, and a person risks losing their balance and falling. As a rule of thumb, the maximum safe reach for an average height person is usually 3’ to 4’ over the ladder size.
|Ladder Size||Approx. Highest Standing Level||Maximum Reach*|
|4'||1' 11"||8' 6"|
|5'||2' 10"||9' 5"|
|6'||3' 9"||10' 4"|
|7'||4' 9"||11' 4"|
|8'||5' 8"||12' 3"|
|10'||7' 7"||14' 2"|
|12'||9' 6"||16' 1"|
|16'||13' 4"||19' 11"|
|18'||15' 3"||21' 10"|
|20'||17' 2"||23' 9"|
Extension/Straight Ladder Heights
When using an extension ladder, the highest permitted standing level is four rungs down from the top. The extension ladder you choose should be 7’ to 10’ longer than the highest support or contact point for your project—which could be the wall or roofline. This allows for the proper setup, section overlap, and the highest standing height.
|Ladder Size||Maximum Extended Level||Maximum Reach*|
*Maximum Reach assumes an a 5’ 7” person with a 12” vertical reach when the ladder is set up at a proper 75.5° angle
**Three-section extension ladder
