Window Cleaning Pole Length Calculator
A pole that is too short leaves your highest windows out of reach, while one that is too long is unwieldy and harder to control. Enter the height of your highest window below to get a recommended water-fed pole length.
Work out the water-fed pole length you need
Enter the height of your highest window above ground level.
For a window at 4m, we recommend a pole length of:
3m
This allows for a comfortable working reach above head height, plus extra pole length below the working end for grip and control.

Frequently asked questions
Why can't I just buy the longest pole available to be safe?
A pole that is much longer than you need is harder to control, heavier to hold up for long periods, and more awkward to manoeuvre around windows, so it is better to size it to the actual height you need to reach.
Do I need a different pole for upstairs windows on a house versus a bungalow?
Yes, upstairs windows on a typical two-storey house sit much higher than bungalow windows, so you will usually need a considerably longer pole to reach them safely from the ground.
Can one telescopic pole cover multiple window heights?
Yes, telescopic water-fed poles extend and retract, so a single pole rated for your highest window will also comfortably reach any lower windows on the property.
Is it safer to use a pole instead of a ladder for high windows?
Generally yes, a water-fed pole lets you clean from the ground without climbing, which removes the fall risk that comes with using a ladder at height.
How this calculator works
The calculator uses your window height measurement in metres to determine the minimum length of water-fed pole needed. We assume a standard ground level and that you’ll be operating from a stable position. The formula is simply: Pole Length (cm) = Window Height (m) x 100. This provides a reasonable estimate for most residential applications, accounting for typical pole designs.
The calculator doesn't account for any potential obstructions like gutters or nearby trees that might reduce the usable reach of your pole. It’s crucial to assess these factors before purchasing a pole and to factor in an extra 10-20cm for maneuverability during use.
Window Height & Pole Reach: A UK Guide
| Window Height (m) | Recommended Pole Length (cm) | Typical Pole Type |
|---|---|---|
| 1.8 | 180 | Standard 25m Pole |
| 2.4 | 240 | 30m or 35m Pole |
| 3.0 | 300 | 40m Pole – Ideal for larger windows |
| 3.6 | 360 | 45m Pole - Consider additional accessories |
| 4.2 | 420 | 50m Pole – Requires careful handling |
Worked example: Calculating the Right Length
Let's say you have a window that’s 2.7 meters tall. Using our calculator, we input this value and get a recommended pole length of 270cm (2.7m x 100 = 270cm). This would be suitable for most standard double-glazing windows in a typical UK home. The price of a 25m water fed pole is currently around £189 on Amazon UK, while a 30m pole can be found for approximately £249.
For particularly tall windows exceeding 4 meters, you’ll likely need to opt for a longer pole – potentially a 45m or even 50m model. Be aware that these longer poles are more susceptible to wind and require greater care when handling them. Always prioritise safety and use appropriate accessories like a trolley for transport.
More questions answered
What units should I use?
The calculator requires window height measurements in metres (m). Ensure you convert any measurements from feet or inches to metres before entering them. A quick conversion is 1 metre = 3.28084 feet.
Does the calculator account for obstructions?
No, it doesn’t. The calculation provides a minimum pole length based solely on window height. Always assess your surroundings – gutters, trees, and other obstacles can significantly reduce effective reach. Add extra length to your calculation if needed.
What happens if I need a slightly longer pole?
It's always better to have a little extra reach than not enough. Adding an extra 10-20cm provides room for maneuvering and ensures you can comfortably clean the entire window surface without struggling.
I’ve measured my window height incorrectly, what will happen?
The resulting pole length will be inaccurate. This could lead to a pole that is too short or unnecessarily long, affecting its performance and potentially increasing the risk of damage if you overextend it.
What's the minimum window height I can use with this calculator?
There isn’t a strict minimum, but we recommend a window height of at least 1.8m (5.9 feet) to ensure you get a reasonable pole length that’s practical for most situations. Smaller windows may not justify purchasing a full-sized pole.
Should I buy a longer pole than the calculator recommends?
It's generally advisable, especially if your windows are particularly high or located in awkward positions. A slightly longer pole offers more flexibility and reduces strain, but also increases the risk of damage with excessive reach.
What accessories do I need to use a water-fed pole?
Essential accessories include a water feed system (hose and tap connector), a cleaning brush or head, and potentially a trolley for transporting the pole. Consider a telescopic handle for easier maneuvering if your window is in a difficult location.
How does the calculator compare to other pole length guides?
Many online guides offer similar calculations based on window height. Our calculator provides a straightforward, easy-to-use method and clearly illustrates the underlying formula, making it reliable for UK homeowners.
Can I use this calculator for commercial properties?
While the basic principle applies to all windows, consider that larger commercial windows might require heavier-duty poles and accessories. Consult with a professional window cleaning service for advice on appropriate equipment.
What if my windows are part of a complicated roofline?
This calculator is best suited for relatively straightforward window access. Complex rooflines may necessitate using an extension pole, a ladder, or seeking assistance from a professional window cleaner to ensure safe and effective cleaning.
