How far apart are the rungs of a ladder?
The distance between rungs, cleats, and steps shall not exceed 12 inches and shall be uniform throughout the length of the ladder. The minimum clear length of rungs or cleats shall be 16 inches.
Rungs, cleats and steps at the base section of extension trestle ladders must not be less than 8 inches (20 cm) nor more than 18 inches (46 cm) apart, between center lines of the rungs, cleats and steps. The rung spacing on the extension section must not be less than 6 inch- es (15 cm) nor more than 12 inches (31 cm).
- The regulations say that if a fixed ladder is taller than 20 feet, you are required to have a cage which meets all the requirements of 29 CFR 1910.27(d). Here are the basics of the requirements: Cages must extend 42 inches above the top of the landing. This is the same height that OSHA requires for guardrail.
- Each year, there are more than 164,000 emergency room-treated injuries and 300 deaths in the U.S. that are caused by falls from ladders. Most ladder deaths are from falls of 10 feet or less. Falls from ladders are the leading cause of deaths on construction sites.
- The official toss line is 15 feet away but most players measure 5 paces from the game ladder to set the toss line. This allows for a closer toss line for children's games. Ladder Golf is played in rounds, each round consists of all players tossing 3 bolas.
For example, a 24-foot extension ladder will consist of two sections each 12 feet long, but the maximum extended length will be 21 feet, because the sections overlap by no less than 1½ feet when the ladder is at maximum extension. The longer the sections, the greater the built-in overlap.

- The SkyScraper is indeed the world's tallest a-frame ladder with a maximum height of 21-feet, making ceiling-height work simple and safe. The SkyScraper is perfect for churches, auditoriums, gymnasiums and other industrial applications.
- A ladder is featured in a Mesolithic rock painting that is at least 10,000 years old, depicted in the Spider Caves in Valencia, Spain. The painting depicts two humans using a ladder to reach a wild honeybee nest to harvest honey. The ladder is depicted as long and flexible, possibly made out of some kind of grass.
A person's maximum safe reaching height is approximately 4' higher than the height of the ladder. For example, a typical person can safely reach an 8' ceiling on a 4' ladder*. Extension ladders should be 7 to 10 feet longer than the highest support or contact point, which may be the wall or roof line.

- When working with electricity or on electrical circuit or equipment, ladder safety should be observed. There are many different types of ladders and they are made of different materials. Metal ladders should never be used when dealing with electricity. Always choose a nonconductive ladder made of wood or fiberglass.
- The height of each storey is based on the ceiling height of the rooms plus the thickness of the floors between each pane. Generally this is around 10 feet (3.0 m) total; however, it varies widely from just under this figure to well over it.
