What Size Ladder for 2 Story House

Choosing the right size ladder for a two-story house is crucial for safety and efficiency. Ladders come in various types, sizes, and materials, each designed for specific tasks and heights. When selecting a ladder for a two-story house, several factors need to be considered, including the height of the house, the type of work to be done, and the user’s weight and comfort. In this detailed guide, we will explore the different types of ladders suitable for a two-story house, their sizes, safety considerations, and tips for proper ladder usage.


Ladders are essential tools for various tasks around the house, especially when it comes to reaching elevated areas like the second story. Whether you’re cleaning windows, painting, or conducting repairs, choosing the right ladder size is paramount to ensure safety and effectiveness. Let’s delve into the different types of ladders suitable for a two-story house and how to select the appropriate size.

Types of Ladders

1. Extension Ladders

Extension ladders are versatile and commonly used for tasks involving the second story. They come in various lengths and can be extended to reach significant heights. When using an extension ladder, ensure it extends at least three feet above the landing surface for stability and safe access.

2. Telescopic Ladders

Telescopic ladders are compact and easily portable. They can extend to different heights, making them suitable for two-story houses. Telescopic ladders are ideal for tasks that require varying heights and are convenient for storage due to their compact size when collapsed.

3. Step Ladders

While step ladders are generally used for lower heights, they can still be suitable for some tasks on the second story, such as indoor painting or changing light fixtures. Step ladders are self-supporting and don’t need external support, making them easy to set up and use.

Choosing the Right Size

1. Measuring the Height

Start by measuring the height from the ground to the point where you need to reach on the second story. Add a few feet to this measurement to ensure the ladder extends above the landing surface. For example, if the height is 15 feet, consider a ladder that reaches at least 18 feet in length.

2. Consider Reach Height

Consider your own height when selecting a ladder. Your reach height is usually about 4 feet higher than your height. For example, if you’re 6 feet tall, your reach height is around 10 feet. Factor in this reach height along with the ladder height to determine the appropriate size.

3. Weight Capacity

Always check the ladder’s weight capacity to ensure it can support your weight along with the weight of tools and materials you might carry while working. Using a ladder with a weight capacity below your total weight can be extremely dangerous.

Safety Considerations

1. Stability

Ensure the ladder is stable on a flat and non-slippery surface. Use ladder stabilizers or levelers if you’re working on uneven ground. Never place the ladder on boxes or other unstable surfaces to increase its height.

2. Proper Angle

Position extension ladders at a 75-degree angle. This means for every four feet of ladder height, the base should be one foot away from the wall. Following this angle enhances stability and reduces the risk of the ladder tipping over.

3. Secure the Top

When using an extension ladder, secure the top to prevent it from sliding sideways. You can use ladder mitts or attach the ladder to a secure point on the building, ensuring it doesn’t shift during use.

4. Maintain Three Points of Contact

Always maintain three points of contact with the ladder—two hands and one foot or two feet and one hand. This provides stability and minimizes the risk of falling. Avoid overreaching; instead, reposition the ladder as needed to maintain proper contact points.


Selecting the right size ladder for a two-story house involves careful consideration of height, type, and safety features. By measuring the height accurately, considering your reach, and accounting for weight capacity, you can choose a ladder that ensures both safety and efficiency in your tasks. Always adhere to proper ladder usage guidelines, and prioritize your safety above all else when working at heights.
