A bay window adds light and space to a room, but dressing it with curtains requires a curtain pole that follows its shape. Unlike a straight wall, a bay has angled sections that need a pole system with bends or flexible tracks. Here is how to measure your bay window accurately, choose between 3-sided, 4-sided, or 5-sided poles, and decide between wall-mounted and ceiling-mounted options.
Start with a metal tape measure and a clear plan. Each section of the bay must be measured separately, and extra length must be added at the ends so curtains can stack back without blocking light. The number of bends in the pole equals the number of wall sections minus one, which is the first concept to understand before buying.
Bay window curtain poles come as rigid pole systems with corner connectors, flexible tracks that bend around angles, or ceiling-mounted solutions for shallow walls above the window. The right choice depends on the bay shape, curtain weight, and the look you want to achieve.

Key Insights for Measuring and Choosing
- Measure each segment of the bay window separately – the number of bends equals the number of wall sections minus one.
- Ceiling-mounted poles offer a cleaner look and work well for shallow bays, but require careful bracket placement.
- Specialist online stores often offer more color/finish options than high-street retailers, but IKEA has affordable friction-fit poles.
- The most common mistake is underestimating the need for additional brackets – use one bracket per bend plus one extra for long straight sections.
- A metal tape measure holds shape around corners and gives more accurate readings than a cloth tape.

What Are the Different Types of Bay Window Curtain Poles?
3-Sided Bay Window Curtain Poles
A 3-sided bay has a left side, a front centre section, and a right side. The pole requires two bends, one at each corner. Most bay pole kits for three sections come as modular systems with pre-cut lengths and corner connectors. When measuring, add 20–30 cm on the first and last sides to allow curtains to stack back without blocking the window.
4-Sided Bay Window Curtain Poles
A 4-sided bay adds an extra angled section, making geometry more complex. Measure each of the four straight sections corner-to-corner. The pole system needs three bends. Not all bay pole kits handle every angle equally well, so check the angle of each corner. A flexible track may be easier if the bay angles are unusual.
5-Sided Bay Window Curtain Poles
Five-sided bays typically have two outer sections, two angled inner sections, and a centre front section. These benefit from a bay-specific curtain pole kit. A kit designed for a 3-sided bay will not suit a 5-sided layout unless it explicitly states compatibility. Measure each of the five sections individually and note the corner angles.
Ceiling-Mounted Bay Window Curtain Poles
Ceiling-mounted systems follow the same measurement method but require attention to ceiling clearance and fixing points. The ceiling must be suitable for fixing – if it is plasterboard, you may need proper anchors or to fix into joists. Ceiling mounting is especially useful when the wall space above the bay is too shallow for wall brackets.
If the distance between the top of the window and the ceiling is less than 15 cm, a ceiling bracket is usually better because wall brackets may be too tight.
Where to Buy Bay Window Curtain Poles and What to Look For
Online Specialist Stores
Specialist online retailers such as Curtain Pole Store and Poles and Blinds offer dedicated bay window curtain pole kits. These stores provide detailed product pages with size options, colour finishes, and often include corner connectors. Made by the Forge specialises in handmade wrought iron poles, offering a premium custom option. The main advantage of online specialists is the wider choice of materials and finishes.
High-Street Retailers (IKEA, B&Q)
IKEA does not sell a dedicated bay window pole system, but you can combine modular rods such as VÄRDE or HUGAD with third-party corner connectors. Some IKEA rods are flexible enough for shallow bends. B&Q sells a range of curtain poles and tracks that can be used for bays, including bendable tracks. A useful measuring guide is available on the DIY.com website. For more on B&Q’s store offerings, see the B&Q Doncaster Store Guide.
Cost and Budget Considerations
Prices range from around £30 for a basic metal set from IKEA to over £200 for a custom wrought iron pole. The average cost for a good-quality bay pole kit is £50–£100. The exact cost varies by material, number of bends, and whether you choose a track or a pole system.
Order a bay pole kit that matches your measured sections. Most kits come with adjustable corner connectors that accommodate a range of angles, but always check the maximum and minimum angle specifications before buying.
How to Install a Bay Window Curtain Pole (Step-by-Step)
Tools Required
You will need a drill, spirit level, screws suitable for your wall type, a metal tape measure, a pencil, and a step ladder. If mounting on a plasterboard ceiling, have appropriate wall anchors ready.
Marking Bracket Positions
Mark the position of each bracket on the wall or ceiling. Use one bracket per straight section plus an additional bracket at each bend for support. For a 3-sided bay with three straight sections, you may need 4–5 brackets in total. Measure twice before drilling.
Fixing Brackets and Assembling the Pole
Drill holes and fix the brackets securely. Assemble the pole sections using the corner connectors provided in the kit. Slide the pole into the brackets, ensuring it sits level. Finally, hang the curtains and make any necessary adjustments.
The most frequent mistake is underestimating the number of brackets needed. Insufficient brackets can cause the pole to sag over time, especially with medium to heavy curtains.
When mounting on the ceiling, verify that the ceiling has enough depth for the bracket and the curtain header. Also check that curtains will not obstruct any handles or window operation below.

What Is Known and What Varies About Bay Window Curtain Poles?
| Established Information | Information That Remains Unclear |
|---|---|
| 3-sided bays require two bends (three sections). | Exact cost varies widely by material and customization. |
| Most bay window curtain poles use a modular system with connectors. | Whether a specific brand (e.g., IKEA) fits your bay depends on your bay’s angles. |
| You can mount a pole either on the wall or on the ceiling. | Some poles require professional installation if the bay is angled unusually. |
Why Do Bay Windows Need Special Curtain Poles?
Bay windows introduce angled corners that a standard straight pole cannot follow. Traditional straight poles would leave gaps at the corners, allowing light to seep through and ruining the neat appearance. Therefore, a jointed pole system or a bendable track is required. Many users on Reddit’s DIYUK community recommend the Silent Gliss Metropole for its durability and smooth operation. Both DIY.com and B&Q offer accessible measuring guides that help users avoid common mistakes.
The choice between a pole and a track often comes down to aesthetics versus practicality. Poles offer a decorative finish with finials, while tracks are more discreet and easier to bend around tight angles. Tracks also glide more smoothly and are often preferred for blackout curtains that need to cover the entire window area without gaps.
What Do Experts and Users Recommend?
“If you like the look of a curtain pole but want something more robust and practical, the Silent Gliss Metropole is the best option.”
– Reddit r/DIYUK (user comment)
“Our bay window curtain poles to suit a variety of shapes of bay windows and any number of bends they may have.”

These sources highlight that both community recommendations and specialist manufacturers agree on the importance of selecting a system designed for multiple bends. The Reddit thread also indicates that many DIYers have successfully installed bay poles themselves, though complex angles may require professional help.
What Should You Do After Reading This Guide?
Start by measuring your bay window using the step-by-step method described above. Decide on the type of pole – wall or ceiling mount, number of bends, and material. Compare prices at IKEA, B&Q, and specialist online stores, then purchase a bay-specific kit. If you need a stylish addition to your living space, a Coffee Table with Storage can complement your newly dressed bay window. Install the pole following the instructions provided, and if in doubt, consult a professional installer for complex bay shapes.
