Curtain poles are a vital component of any window treatment, providing both functionality and aesthetic appeal. To ensure your curtains hang flawlessly and complement your room’s decor, it’s crucial to measure for your curtain pole correctly.
Curtain poles come in a wide range of styles, materials, and finishes, allowing you to choose the perfect option for your home. However, selecting the right size curtain pole is essential to achieve a polished and professional look.
This guide will walk you through the step-by-step process of measuring for a curtain pole in the UK, considering various factors and offering valuable tips.
Tools You Will Need
Before you begin measuring, gather the following tools to ensure you have everything you need:
- Measuring Tape: A sturdy, flexible tape measure is ideal for accurate measurements.
- Pencil and Notepad: For marking measurements and jotting down details.
- Step Ladder: If you have tall windows, a step ladder will help you reach higher points safely.
- Spirit Level: Useful to ensure the pole is level when marking the wall for bracket placement.
Using the right tools not only simplifies the process but also guarantees that your measurements are accurate and precise.
Step-by-Step Guide
1. Determine Pole Length:
- Measure Window Width: Use a measuring tape to determine the width of your window opening. Ensure you measure the widest part of the opening, including any frame or molding.
- Consider Pole Extension: Decide how far you want the curtain pole to extend beyond the window frame on each side. This typically ranges from 15 to 30 centimeters (6 to 12 inches). A longer extension can provide better light control and enhance the overall aesthetic.
- Calculate Pole Length: Add the width of your window opening to the desired extension on both sides to obtain the ideal length for your curtain pole. For example, if your window is 120 centimeters wide and you want a 20-centimeter extension on each side, your pole length would be 160 centimeters.
2. Decide on Pole Projection:
- Measure Desired Projection: Determine how far you want the curtain pole to project from the wall. This is typically measured from the wall to the center of the pole. Factors to consider include the style of your curtains, the size of your room, and your personal preference.
- Common Projections: Popular projections range from 15 to 25 centimeters (6 to 10 inches). A shorter projection can create a more minimalist look, while a longer projection can add a touch of drama.
3. Measure for Brackets:
- Mark Bracket Placement: Once you’ve determined the pole length and projection, mark the wall where you want the brackets to be placed. Ensure the brackets are positioned at a consistent height.
- Consider Curtain Thickness: The thickness of your curtains will influence the distance between the brackets and the wall. For thicker curtains, you may need to install the brackets slightly further out from the wall to allow for proper drapery.
4. Additional Considerations:
- Curtain Heading Style: Different curtain heading styles (e.g., pinch pleat, tab top) require different pole widths. Refer to your curtain manufacturer’s instructions or consult with a professional for specific recommendations.
- Window Treatments: If you’re using blinds or shutters, factor in their width when measuring for the curtain pole. Ensure the pole is wide enough to accommodate both the curtains and the window treatments.
- Ceiling Height: For high ceilings, you may need to use a longer curtain pole and additional brackets to ensure the curtains reach the desired length.

Tips and Tricks

- Measure Twice, Cut Once: Double-check your measurements before purchasing or cutting your curtain pole to avoid mistakes.
- Consider Finials: If you plan to use decorative finials on your curtain pole, factor in their length when measuring.
- Seek Professional Help: For complex window shapes or custom installations, consulting a professional curtain fitter can be beneficial.

Common Mistakes to Avoid
When measuring for a curtain pole, there are several common mistakes to avoid:
- Not Allowing Enough Overhang: Failing to add extra length beyond the window frame can result in curtains that don’t fully cover the window.
- Incorrect Bracket Placement: Placing brackets too close to the window frame can cause the pole to be unstable. Always measure and mark the bracket positions carefully.
- Misjudging the Curtain Drop: Ensure you have measured the drop correctly to avoid curtains that are too short or drag on the floor.
By being mindful of these mistakes, you can save time, effort, and expense in correcting them later

Frequently Asked Questions (FAQs)
To measure for a curtain pole, start by measuring the width of your window from one side of the frame to the other. Then, add an extra 15-20 cm (6-8 inches) on each side for the curtains to stack back properly when opened. The total width will be the size of the curtain pole you need.
Choose a curtain rod that is 30-40 cm (12-16 inches) wider than your window frame. This allows the curtains to fully cover the window when closed and stack neatly to the sides when open. Also, consider the length of your curtains and how much you want them to overlap the window frame.
For 90×90 curtains (229 cm width x 229 cm drop), you should choose a curtain pole that is at least 270-290 cm long. This length includes the extra allowance on both sides (about 15-20 cm each) for the curtains to hang correctly and stack back when open.
A curtain pole should be 30-40 cm (12-16 inches) wider than the window. This extra width allows for proper curtain stacking and ensures the window is fully covered when the curtains are closed.
