In no way, how high will a 12 foot extension ladder reach? Size
Max. Height You Want to ReachBuy This Size Ladder (assumes vertical 12-inch reach)
| 11 feet | 7-foot |
| 12 feet | 8-foot |
| 14 feet | 10-foot |
| 16 feet | 12-foot |
So anyway, how do you measure a ladder?
Here's the calculation to determine the pitch of the extension ladder: place the feet of the ladder one (1) foot away from the wall for every four (4) feet of extended ladder height. An example would be a twenty (20) foot extended ladder (divided by four) should be placed five (5) feet away from the wall.
What size ladder do I need for 2 story house?
As mentioned earlier, due to overlapping of the base and flying section, an extension ladder reaches about 3 feet less than its total height. So, the required ladder size for a 2-story house is 21+3=24 ft. where the maximum reach is 21 feet.

D-shaped rungs are less angular than square rungs, and they're designed to be more comfortable to stand on. The flat surface is ideally angled for safe, comfortable footing. Most of our extension ladders have D-shaped rungs, although we do sell some square-runged and round-runged products available too.

The base of the ladder should be placed so that it is one foot away from the building for every four feet of hight to where the ladder rests against the building. This is known as the 4 to 1 rule.
To work safely, your extension ladder needs to be pitched at a ratio of 4:1. So for every 4 feet up, you need to move the ladder 1 foot out. This is known as the '1 in 4' rule. So, if you want to work on a 20ft wall, the ladder needs to be moved 5ft out.
It has been determined that you are meeting the intent of the standard which is to provide a uniform clear distance of 12" equally spaced between rungs of your ladders on the described project.

The simple rule is for every 4 feet you go up, you bring the ladder out 1 foot. So for example, the general height of a two story house (up to the eves) will be 4.7m, which equates to 15”5. For this height you would bring you ladder out 3 feet 10¼ inches to be exact!
For a two storey house you would need an extension ladder with an extension of around 7m. This takes into account the 4 to 1 placement of the ladder angle and variations in gutter height. Our AEEND EN131 Professional aluminium extension ladders would be suitable ladders for this task.
A rough guide would be to say most bungalow and single storey homes gutterline in the UK are around 3.3 metres in height. This means a 8-10 tread step ladder would be sufficient to carry out your gutter clean. Most 2 storey UK homes gutters are approximately 5.7 meters in height.
SHORT ANSWER: No, it's not safe to lean a ladder against a gutter. Make sure you lean your ladder against a strong resting point that's sturdy enough to support it.
Fiberglass tends to be much stronger than aluminum. This doesn't mean aluminum ladders are not strong. ... An aluminum ladder is fairly resistant to weather, but a fiberglass ladder is even more resistant. In addition, fiberglass ladders are resistant to electricity, which means they are safer around power lines.

Use the 4-to-1 rule: Make sure the ladder is 1 foot away from the wall for every 4 feet that the ladder rises. For example, if the ladder touches the wall 16 feet above the ground, the feet/base of the ladder should be 4 feet from the wall.
The correct angle for a ladder is 75 degrees or the 1 in 4 rule.
An example of the '1 in 4' rule in action If the ladder meets the wall at a point that's exactly 4 metres off the ground, the foot of the ladder should be positioned precisely 1 metre away from the wall. If the ladder reaches 8 metres off the ground, place the bottom of the ladder 2 metres back from the wall.
Single and extension ladders may be used by more than one person at a time. Ladders must not be placed in front of closed doors. ... The maximum extended length of an extension ladder is the same as its size.
Extension ladders range in length from 16 feet up to and exceeding 40 feet. All non-self supported ladders should extend a minimum distance of 3 feet past the edge they rest against but not more than 4 feet.
An extension or straight ladder used to access an elevated surface must extend at least 3 feet above the point of support (see diagram).
