How to Get the Correct Ladder Angle

Each time you use a ladder, you have to run through a kind of mental checklist to make sure you are using your ladder as safely as possible. One of the most important steps when setting up an extension ladder is making sure the ladder is at the correct angle. When an extension ladder is being used, it should be at a 75.5-degree angle. Now, that may sound complicated, but there are lots of easy methods and tools that have been created to help the user find the correct angle.


NIOSH (National Institute for Occupational Safety and Health) created an app with great ladder safety tips. The app includes information on how to do a thorough ladder inspection. It also has a way to check the ladder's angle. Checking the angle with the app is simple. All you have to do is open the app and set your phone on the ladder rung. The app then tells you if you need to have your ladder less or more steep.

Bubble Indicators

Some ladders, including the Little Giant HyperLite and Little Giant SumoStance ladders, have bubble indicators that show the operator when the ladder is level. These indicators help the operator know at a glance if the ladder needs to be made more or less steep.

The 4-to-1 Rule

If you don't access to a ladder with bubble indicators or the NIOSH app, the next best thing is to think of the 4-to-1 rule for ladder safety. For every four feet of ladder height you are climbing, move the base of the ladder one foot from the wall.

We hope you take these tips to heart. Following these tips will help you climb safely when using an extension ladder, so you can complete your job and not become a statistic.
