Choosing the right sized ladder for your construction needs is critical for both safety and effectiveness. Whether you’re a homeowner tackling DIY projects or a professional contractor, understanding ladder sizes and types will help you make an informed decision.
Step Ladders
Step ladders are self-supporting and ideal for indoor use and light outdoor tasks. They come in several heights:
- 4-foot: Perfect for reaching 8-foot ceilings and changing light bulbs
- 6-foot: Ideal for most household tasks, painting, and accessing 9-10 foot ceilings
- 8-foot: Suitable for commercial applications and higher ceilings
- 10-foot and above: Primarily for industrial use
Best For: Interior painting, changing light fixtures, decorating, and accessing kitchen cabinets. Choose a 4-6 foot model for typical household use.

- 24-foot: Extends to 21 feet, ideal for professional use
- 28-foot and above: Commercial and industrial applications
Best For: Exterior painting, roof access, gutter cleaning, and tree trimming. A 20-foot model suits most residential needs.

Multi-Position Ladders
These adaptable ladders can be configured in multiple ways:
- 11-foot: Converts to a 5-foot stepladder
- 13-foot: Converts to a 6-foot stepladder
- 17-foot: Converts to an 8-foot stepladder
- 22-foot: Converts to a 10-foot stepladder

Platform Ladders
Platform ladders provide a stable standing area:
- 2-3 foot: Light duty, household use
- 4-6 foot: Commercial applications
- 8-10 foot: Industrial settings
Best For: Extended-duration tasks requiring stability and comfort. Choose 2-3 foot for home use.
Choosing the Right Ladder: Key Considerations
1. Height Requirements
- Add 3 feet to the height you need to reach
- For extension ladders, divide the working height by 4 to determine minimum ladder length
- Never stand on the top three rungs of any ladder
2. Weight Capacity (Duty Ratings)
- Type IAA (Special Duty): 375 lbs
- Type IA (Extra Heavy Duty): 300 lbs
- Type I (Heavy Duty): 250 lbs
- Type II (Medium Duty): 225 lbs
- Type III (Light Duty): 200 lbs
3. Material Choices
- Aluminum: Lightweight, corrosion-resistant, ideal for most uses
- Fiberglass: Required for electrical work, durable but heavier
- Wood: Traditional choice, affordable but requires maintenance

Many construction projects will use either aluminum or fiberglass. We cover more about aluminum vs fiberglass ladders and which is right for you in our article linked here.
