What Ladder Height Do I Need? A Practical Guide by Cocus
What Ladder Height Do I Need? How to Choose the Right Ladder for Every Job
Picking the right ladder height is one of those decisions that seems straightforward until you're standing on the wrong rung. From changing a lightbulb to cleaning gutters, every task needs a different working height — and getting it wrong is both inconvenient and genuinely dangerous. This guide covers how to match ladder height to your job, with specific size and pricing information for the Climb-It Professional Step Ladder range available from Cocus.
Why Ladder Height Matters
The right ladder height isn't just about reaching your goal — it's about maintaining stability and a safe working position throughout the task. The key rule: always keep two rungs between you and the top of the ladder. That means your working reach is roughly 1–1.2m above the ladder's stated platform height.
Key Factors to Consider
- Reach height: Your reach is approximately 1.2m above the platform height — a 1m platform gives roughly 2.2m working reach.
- Working environment: Ceiling height, available floor space, and surface stability all affect which ladder is right for the job.
- Task duration: For short tasks, any stable ladder will do. For extended work at height, a platform ladder with a standing area is more practical.
Types of Ladders and Their Optimal Uses
1. Step Ladders
Self-supporting and stable, step ladders are the go-to for indoor work and most small-to-medium outdoor tasks. They don't need to lean against a wall or structure, making them versatile and quick to set up. The Climb-It Professional Step Ladder range covers 3 to 7 treads, with platform heights from 670mm to 1710mm — suitable for the majority of maintenance, trade, and facilities tasks.
2. Extension Ladders
For gutters, rooftops, and high exterior walls, extension ladders provide greater reach than a step ladder. These lean against a wall or structure for support, so a stable surface at the base and a suitable point of contact at the top are both essential.
3. Platform Ladders
Where you need to work at a fixed height for extended periods, a platform ladder provides a standing area at the top — more comfortable and stable than balancing on a rung. Suited to trade professionals carrying out prolonged overhead work.
Choosing the Right Height: Indoor Jobs
For most indoor tasks — painting walls, changing lightbulbs, reaching high shelves — a 3- to 6-tread step ladder covers the majority of scenarios. Use the table below to match your task to the right size:
- 3 Treads — platform height 670mm — reaching low shelving, low-level maintenance. From £110.34.
- 4 Treads — platform height 930mm — light maintenance, standard ceiling lightbulbs. From £125.94.
- 5 Treads — platform height 1,190mm — higher ceilings, top of standard shelving units. From £146.34.
- 6 Treads — platform height 1,450mm — high shelving, tall interior walls, warehouse racking. From £169.14.
Choosing the Right Height: Outdoor Jobs
For exterior work — trimming hedges, cleaning gutters on a single-storey building, or accessing roof edges — the taller sizes in the step ladder range are appropriate on firm, level ground. For two-storey or higher work, an extension ladder is the safer choice.
- 6 Treads — platform height 1,450mm — single-storey gutter cleaning, exterior painting. From £169.14.
- 7 Treads — platform height 1,710mm — reaching higher single-storey eaves, tall exterior walls. From £189.54.

Ladder Safety: Key Rules
- Inspect before you climb: Check for cracks, loose parts, or worn feet before use.
- Stable surface only: Ensure the ladder is on flat, firm ground. Never place on a box, pallet, or uneven surface.
- Don't overreach: Keep your body between the stiles (side rails). If you're reaching sideways, move the ladder instead.
- Two rungs from the top: Don't stand on the top two rungs unless the ladder has a designated standing platform at the top.
- Three points of contact: Two feet and one hand, or two hands and one foot, on the ladder at all times when climbing.
Frequently Asked Questions
1. Can I use one ladder height for all jobs?
No — different tasks need different working heights, and using a ladder that's too short means overreaching, which is a leading cause of ladder accidents. If in doubt, always go one size up.
2. How do I calculate the reach height I need?
Your working reach is roughly 1.2m above the ladder's platform height. So a 5-tread Climb-It with a 1,190mm platform height gives you a working reach of approximately 2.4m — enough for most ceiling work in a standard room.
3. Are step ladders safe for outdoor use?
Yes, provided they are on firm, flat ground. The Climb-It Professional Step Ladder range is designed for both indoor and outdoor use, with non-slip feet that perform well on most surfaces. Avoid use on soft or uneven ground without a suitable base board.
4. What's the maximum weight capacity on a Climb-It ladder?
150kg — sufficient for the user plus a standard tool kit. For heavier loads or industrial applications, check the product specification before use.
5. How should I store a step ladder?
Fold closed and store horizontally, or hang vertically against a wall. Keep in a dry location to prevent corrosion. Inspect for damage after any knock or drop before returning to service.
6. Are taller ladders less stable?
Not inherently — stability is a function of design and use, not height. The Climb-It Professional range is designed with a wide stance and reinforced platform at every size, so the 7-tread is no less stable than the 3-tread when used correctly on a flat surface.
Conclusion
The right ladder height is the one that lets you work comfortably at the right level without overreaching — and for most trade and facilities tasks in the UK, the Climb-It Professional Step Ladder range covers everything from 3-tread (670mm platform) through to 7-tread (1710mm platform). All sizes are EN 131 certified, rated to 150kg, and available with next-day delivery from our Manchester warehouse.
