Ladder Angle Rule 4 to 1 & Ladder Safety Tips

Setting Up a Ladder

Before leaning your ladder against the wall, you should pay attention to ladder safety.  When we’re talking about ladder safety, it’s actually about having the right ladder angle.  

So, what’s the perfect ladder angle?  Well, check them out below:  

1. According to the HSE, it has to have an angle of 75 to 75.5 degrees for it to be considered safe.  This angle is crucial, especially when using ladders that don’t have much support, such as the extension, straight, and single-pole ladders.  When using such types of ladders, it is a must that you adhere to the ladder safety standards.

2.  Here’s another method on how you can get the right ladder angle.  It is known as the 4 to 1 ladder angle rule.  The main purpose of the 4  to 1 ladder angle rule is to achieve balance and stability.    

This rule is performed by considering a 1-meter gap from the wall to the base of the ladder for every 4-meter height that you’ll climb.  

So, for instance, if you are to climb an 8-meter high wall, you need to maintain a gap of 2 meters from the wall to the base of the ladder.  Therefore, the higher the working height is, the wider the gap is horizontal.  

Make sure that the gap between the base and the wall is not exceedingly far or not overly close.  Too far could possibly make the ladder slide and being too close could topple it off. 

So, to avoid ladder accidents, you should know the drill – know how to properly angle the ladder.  Seemingly a very simple reminder, but can actually have an enormous impact on our lives.  

Checking the Ladder’s Right Angle

It’s already been mentioned that the best ladder angle is 75 degrees.  But how do you determine a 75-degree angle?  Simple – use a measuring tape! Or, for the ladder experts, they already know how that angle looks like.    

4 to 1 Ladder Angle Rule

Before you begin taking the angle, you first need to determine the working height.  Once you have measured the working height, divide it by 4.  The answer you’ll get is the right distance from the base of the ladder to the wall.  

This is also known as the “4 up, 1 out” rule.   

Stand and Reach

This is a much easier method.  The steps are so easy to follow:

  • Lean the ladder against the wall.
  • Stand right behind the ladder with your feet touching its base.
  • Then put one arm forward leveled at your shoulder.  
  • Finally, reach for the ladder’s rung.  If you can easily touch the rung, it means you have the right ladder angle.  

Types of Ladders   

  1. Stepladder: this is a short ladder that is composed of flat rungs with non-adjustable legs.  The step ladder does not belong to the pile of self-support ladders.   
  2. Single Ladder or Straight Ladder is a fixed ladder, which cannot likewise be adjusted.  It only consists of a lone section and is not also a self-support ladder. 
  3. Extension Ladder: Unlike the step and single ladders, this type has adjustable legs.  Yet, it still is not self-supporting.  

Portable Ladder Requirements

  • For step ladders, they should not exceed 20 feet.  For it to be considered safe, it must have a metal spreader or a locking mechanism that is sufficient in size and highly durable.  
  • For the single/straight ladders, it must not exceed 30 feet.  
  • For best extension ladders, they must have a maximum ladder height of 60 feet.  
  • For the safety of the users, ladders must be in excellent working conditions at all times.
  • The ladder’s feet must be well-secured and so is the surface where the ladder will be positioned.  
  • If possible, secure the ladder by tying it up in different sections, preferably at the bottom, middle and top, to prevent it from slipping.   
  • When climbing up to a roof, the ladder must have a buffer length of at least 3 feet.  The excess part shall serve as support when going up and down.  
  • It is mandatory for users to climb up and down the ladder facing it since the steps or ladder’s rungs will be more visible.  
  • Never combine 2 separate ladders to make a longer ladder.  
  •  It’s a no-no to use ladders as scaffoldings or platform ladders.  
  • Your hands must be free when going up and down the ladder.  
  • Do not use metal ladders when doing electrical stuff.  

Four Ladder Safety Tips/Rules

These safety rules are applicable to ladders that are usually entailed to lean against walls, which includes extension, telescopic, and leaning ladders.  

RULE 1: When doing certain tasks that make use of ladders, see to it that you use the correct type and length of the ladder.

RULE 2: Before stepping into a ladder, it is important to inspect all its parts.  It must be in perfect working condition.  

RULE 3: Follow the 4 to 1 rule when setting up a ladder, which is discussed in this article. 

RULE 4: Having the proper environment should also be considered when working on a ladder.

Among these rules, rule number 3 will be given more importance as this is all about achieving the ladder’s stability and the user’s safety.    


Knowing the ladder correct angle rule poses great importance as it is synonymous with safety, balance, and stability.  The 4 to 1 proper ladder angle rule is one rule that we should be knowledgeable of.  

Familiarize yourself with the right ladder angle to avoid accidents.  The balance of your ladder will depend much on its angle.   

So, whether you’re an expert or not, oblige yourself to learn more about the 4 to 1 ladder angle rule.  It pays to have great knowledge!
