An extension ladder is often a great choice. It can be adjusted to the appropriate height for reaching the second story. Look for ones with good stability and a high weight capacity.
A telescoping ladder is quite suitable. It's easy to store as it can be collapsed to a compact size. And it can be extended to reach the second - story height. Brands like Xtend & Climb offer good quality telescoping ladders.
A typical two-story ladder is around 12 - 15 feet tall. This range takes into account different types and models. Some might be a bit shorter or taller, but it's generally within this range to reach the second floor safely.
I think the best 3-story fire escape ladder is one that's made of strong and durable materials like steel and has secure rungs and handrails for a safe descent.
For a typical two-story house, you might want to consider a ladder that's at least 16 feet. However, it depends on the height of each floor and the specific tasks you'll be doing. If you need to reach the gutters or do more extensive work, a 20-foot or even 24-foot ladder could be better.
For a typical two-story house, a ladder around 18 to 24 feet would likely do the job. But you should always consider additional height for safety and ease of access. Also, make sure the ladder is stable and rated for the weight you'll be putting on it.
It depends on the height of the two-story house. Generally, a ladder of around 20 feet might be sufficient, but it's best to measure the exact height from the ground to the roofline to determine the right size.
