Step Ladders (A-Frame)

Step ladders are self-supporting and ideal for tasks at low to medium heights. Sizes are measured by the number of steps and their total height.

• 4-foot ladder: Perfect for indoor chores like changing light bulbs or reaching top shelves. Maximum reach height: ~8 feet.
• 6-foot ladder: A versatile choice for most homeowners. Useful for painting, decorating, or accessing attics. Maximum reach height: ~10 feet.
• 8-foot ladder: Excellent for reaching the ceilings of standard rooms or for outdoor use on single-story homes.

Extension Ladders (Straight Ladders)

Extension ladders lean against a surface and are used for accessing high areas like roofs or gutters. They consist of two or more sections that slide apart. Sizes refer to the maximum extended length.

• 16-24 foot ladder: Suitable for single-story homes. Reaches eaves, gutters, and most first-story roofs safely.
• 28-32 foot ladder: The standard for two-story homes. Allows safe access to second-story windows and roofs.
• 40+ foot ladder: Used for professional and industrial applications on three-story buildings and higher.

Safety Note: Extension ladders must extend至少 3 feet above the roof line or landing point for safe transition.

Multi-Purpose & Telescopic Ladders

These highly adaptable ladders can be configured into various shapes (step, extension, staircase). Their compact design makes them great for storage. Heights are adjustable, often ranging from about 9 feet as a step ladder to over 15 feet fully extended.

How to Choose the Correct Height

To calculate the right extension ladder size, estimate the height you need to reach. A simple rule is that the ladder’s base should be 1 foot away from the wall for every 4 feet of height to the support point (the 4-to-1 rule). Always choose a ladder slightly taller than you think you’ll need to ensure you never have to stand on the top cap or top three rungs.
