**What is the 1 in 4 rule for ladders**

When placing your ladder, remember the four-to-one rule: for every four feet of height you have to climb, move the base one foot away from the wall.

The average 2 floor house will be just 7 metres or 23 feet in height. This means that the base of the ladder must be placed just over 1.75 metres or approx 5.75 foot away from the base of the house wall. The top of the ladder must extend beyond the roof edge by approximately 100cm.

Ladders need to be at an angle of 75 degrees away from the wall. This is known as the 1 in 4 rule. To get the angle right, you will need to know how far off the ground your roof is. If the ladder pitch is not correct, there is a serious risk of the ladder slipping or tipping away from the wall when in use.

So assuming our measurements for the 2 floor/ storey house that is 7 metres or 23 feet in height with a Base of 1.75 meters or 6.75 feet, we then need to use the Pythagoras Theorem to work out the ladder length. Ladder length √ 7^2+ 1.75^2 = √49 + 3.0625 = 7.2 metres or 23.5 feet, add approximately 1 more metre for ease to account for additional extension beyond the roof edge, which means you would need a ladder of just over 8m or 26 feet in height.

Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line. This will allow enough length for proper setup, the overlap of ladder sections, height restrictions of the highest standing level, and where appropriate, the extension of the ladder above the roof line. The highest standing level is four rungs down from the top.
