What is the difference between a step ladder and a ladder?

Last Updated on August 26, 2022 by William R. Vargas

From time immemorial, people have gone to the extremes of breaking their lungs, if not legs. Lucky are you if you never experienced a severe downfall while trying to fix your shelve or a mere bulb holder.

Occasionally, tasks such as construction, industrial, household activities, and gardening can be overwhelmingly challenging in performance and exposure to risks.

You will need a Ladder and Step Ladder as alternative supporting equipment to conveniently perform such tasks to access high endpoints.

A ladder consists of steps between two parallel metallic or wooden support lines. It is portable and can be extended to attain greater heights. However, it is not self-supportive and thus needs to be leaned against an object or a flat surface.

On the other hand, a step ladder is v-shaped and consists of two ladders co-joined at the top with hinges. It is self-supportive and thus does not need to lean on objects or flat surfaces for stability.

Choosing between the two is dependent on the type of task, duration, target height, efficiency, load capacity, safety, and portability.

Improper use may result in physical injuries, deaths, and disabilities.

Therefore, there is a need to maintain high safety standards while on board.

What is a Ladder?

A Ladder comprises two side rails and a rung in between, which act as a stepped base for the user to step while climbing up or down.

A ladder cannot stand on its own and thus will need to lean against surfaces or objects for support.

Extension hooks, stirrups, swing hooks, and push-up hooks act as fittings to lock up a ladder. A ladder should be placed on a firm base support surface, and the user should ascend or descend while facing it.

A ladder can be straight or with extensions, depending on the target height.

What is a Step Ladder?

A Step ladder is portable and consists of newels on the sides with flat steps. It is self-supportive; thus no need to lean on other objects.

The size of a Step ladder ranges from 4 to 20 feet, with a standing level capacity of more than 2 feet from the top of the ladder.

The maximum working height capacity is achieved by adding the user’s height and the highest standing capacity level of the step ladder. A step ladder is non-adjustable in length.

What is the difference between a Step Ladder and a Ladder?

Choosing between a Ladder and a Step Ladder is a challenge. However, users should choose the two based on occasion and the intended use.

The visible difference between a ladder and a step ladder is that a step ladder is self-supporting, while a ladder must lean on an object or surface for support.

Often, ladders can be single or with extensions. The height is determined by the highest point of reach or target.

Ladders are widely used in outdoor activities since they can be extended to achieve certain heights. In contrast, step ladders are used for light outdoor and indoor activities where no greater height extension is needed.

How tall of a step ladder do I need?

A ladder is used to perform tasks beyond the natural heights of the worker.

Unless otherwise stated by the manufacturer, the standard rule is that you should always stand two steps below the top. A step ladder can reach heights between 8-14 feet, depending on the type of task.

The user’s standard reaching height is 3-4 feet higher than the ladder’s height. This assures the user maximum stability and ease of performing tasks.

For instance, for a task that is 12 feet in height, you will need to subtract the working area allowance, which is 4 feet, to get 8 feet as the height of the step ladder needed.

When should you use a step ladder?

  • Match the recommended weight capacity of the step ladder with the user’s weight plus any other tools.
  • The step ladder should be 1 meter below the highest target point and the feet rails firm on the surface for stability.
  • Ensure the step ladder is in good condition, with no worn-out parts, missing parts, or presence of visible grease or slippery parts.
  • The step ladder spreaders and shelf should be opened fully and adjusted and the braces locked.
  • Keep the ladder close to the work, with the right angle and either side of the steps should face the work.
  • Pulling or pushing a ladder is not recommended as this will weaken them.
  • Always face the ladder while ascending or descending with your body well centered.
  • Always wear the right gear to maintain a firm grip.
  • Use both hands for support while climbing and maintain a three-body point rule approach.

Is it safe to use a step ladder as a straight ladder?

Absolutely No. It is culturally unsafe to use a step ladder in a leaning and folded position as a straight ladder. It is used in an open position.

This will affect the step ladder balance and stability. The outcome is increased chances of falling off, injuries, and obstruction.

While using a step ladder, consider wearing the right gear, preferably footwear with a reliable tread for grip while asking or descending off the ladder.

Otherwise stated, never stand on the top two steps of the ladder. Always follow the manufacturer’s user manual guide.


Preferences for a ladder and a step ladder are dependent on their intended use, safety, weight, height, portability, duration, and platform size.

The user’s height and the maximum height allowance from the top of a ladder base determine the highest capacity height.

Safety measures, the right gear, weather extremes, and proper equipment maintenance procedures should be adhered to as they significantly reduce risk incidences resulting from falling off or obstruction from objects.

Three-point body rule forms the basis of proper user safety guidelines, thus significantly reducing physical injuries, accidents, and unwarranted deaths due to improper choice and equipment use.

Always match your ladder choice with the task ahead.
