Taking the time to pick right extension ladder can be a confusing decision. The easiest way to decide what size ladder you need is to figure out what the ladder will be used for.

The Simplest Rule

Every 4 metres up needs 1 metre out

What Height Do You Need To Work At?

How to work out your ladder height requirements:

From ground level to the apex of your roof will be approximately the same height as 3 floors.


If you have a 2-story house and the height of your ceilings is 2.35m (average height) then the height from the ground to your eaves will be approximately 2 x 2.35m 4.7m



Add 1.1m to your working or step-off height to calculate what size of extension ladder you need.


Job Examples:


1.Painting 1st Floor Windows
Typical height of job (approx): Up to 4.7m (Eaves)
Ladder required 3 x 2.5 which when fully extended is 5.5m

2. Gutter Maintenance and Repair
Typical height of job (approx): 4.7 (Eaves)
Ladder required 3 x 2.5 which when fully extended is 5.5m

3. Painting Exterior
Typical height of job (approx): Up to 7.05m (Apex)
Ladder required 3 x 4.2m which when fully extended  is 10m
