# All About a 5, 6, 7, 8, 10, 12, 13, 15 and 16 rung ladder

## How tall is a 5, 6, 7, 8, 10, 12, 13, 15 and 16 rung ladder

A ladder is a tool commonly used by civil engineers for accessing heights and completing various construction and maintenance tasks. Ladders come in different sizes and configurations, with varying numbers of rungs or steps, making them suitable for different applications. In this article, we will determine the height of ladders with 5, 6, 7, 8, 10, 12, 13, 15, and 16 rungs, based on their standard dimensions and the formula for calculating ladder height.

The height of a straight ladder, also known as the working length, is the vertical distance between the ground and the top of the ladder. This measurement is essential for determining its suitable use and ensuring safety. The height of a ladder is generally labeled on the side rails, but as a civil engineer, it is crucial to know how to calculate it yourself.

To calculate the height of a ladder, we can use the following formula:

Ladder height = (Number of rungs – 1) x Rung spacing

Rung spacing is the distance between each rung, which is typically 12 inches (30.48 cm) for most ladders. For ladders with a rung spacing other than 12 inches, you can adjust the formula accordingly.

Now, let’s determine the height of each ladder:

– 5 rung ladder: According to the formula, the height of a 5 rung ladder would be (5-1) x 12 inches = 48 inches (121.92 cm). This ladder would be about 4 feet tall.
– 6 rung ladder: Using the same formula, the height of a 6 rung ladder would be (6-1) x 12 inches = 60 inches (152.4 cm). This ladder would be 5 feet tall.
– 7 rung ladder: The height of a 7 rung ladder would be (7-1) x 12 inches = 72 inches (182.88 cm), or 6 feet tall.
– 8 rung ladder: For an 8 rung ladder, the height would be (8-1) x 12 inches = 84 inches (213.36 cm), or 7 feet tall.
– 10 rung ladder: Using the formula, the height of a 10 rung ladder would be (10-1) x 12 inches = 108 inches (274.32 cm), or 9 feet tall.
– 12 rung ladder: The height of a 12 rung ladder would be (12-1) x 12 inches = 132 inches (335.28 cm), or 11 feet tall.
– 13 rung ladder: For a 13 rung ladder, the height would be (13-1) x 12 inches = 144 inches (365.76 cm), or 12 feet tall.
– 15 rung ladder: The height of a 15 rung ladder would be (15-1) x 12 inches = 168 inches (426.72 cm), or 14 feet tall.
– 16 rung ladder: Lastly, the height of a 16 rung ladder would be (16-1) x 12 inches = 180 inches (457.2 cm), or 15 feet tall.

It is important to note that the height of a ladder may vary slightly from the calculated measurement depending on the

## Conclusion

In conclusion, the 5, 6, 7, 8, 10, 12, 13, 15, and 16 rung ladder offers a wide range of options for any situation that requires reaching heights. From household tasks to professional jobs, these ladders provide stability, versatility, and safety. It is important to choose the right ladder for the task at hand and to use it properly. With the proper care and maintenance, these ladders can last for many years and be a valuable tool for any individual or organization. So whether you are a homeowner or a contractor, consider investing in one of the various rungs ladders to make your work easier and safer.
