What is the ladder safety ratio description?

The ladder safety ratio describes how far the base of the ladder should be from the wall relative to how high you climb. The standard rule is four feet up for every one foot outward from the wall, which puts the ladder at about a 75-degree angle. This angle helps keep the center of gravity over the base, giving stable footing and reducing the risk of tipping or slipping. The described ratio—four feet of rise for one foot of separation—matches this safe guideline exactly, which is why it’s the best description. Ratios that give a shallower or steeper angle would place the base too close or too far from the wall and compromise stability, so they don’t meet the recommended safety standard.
