Angled and curved windows
TrackFit installs curtain tracks for angled, curved, square and unusually shaped bay windows across the United Kingdom. Each project is assessed for measurements, corner movement, fixing strength, curtain weight and available clearance.

Direct answer
A bay window curtain track is a straight, joined or shaped track designed to follow the internal outline of a projecting window. Depending on the bay, it may include angled corners, curved sections or multiple returns. Correct installation requires accurate measurements, smooth runner movement through the corners, suitable structural support and enough clearance for the curtains to hang and stack correctly.
Bay-window shapes
Bay windows vary significantly. The correct track and fitting method depend on the angles, radius, fixing surface and the type of curtain being installed.
Straight track sections joined or formed around defined corners, commonly found in three-sided and five-sided bay windows.
Track systems shaped to follow a continuous radius or rounded architectural window.
Tracks fitted around projecting windows with more pronounced internal corners and returns.
Specialist assessment for windows with sloping ceilings, changing heights or non-standard geometry.
Installation process
Enter the installation postcode, property type, estimated track quantity and the closest track option.
Include the full bay, ceiling, side walls, corners, window handles and any existing fittings.
The TrackFit team checks the bay shape, proposed fixing surface, access and curtain requirements.
The approved track is prepared, positioned, fixed securely and tested through the full bay.
Technical assessment
Bay tracks have more variables than a straight installation. The track must follow the window while still supporting reliable curtain movement.
Each straight section, corner angle, radius, return and projection must be measured accurately. Small errors can prevent a shaped track from fitting correctly.
Runners must travel through bends and joins without catching. Sharp angles may require specialist components or separate track sections.
The available fixing surface determines the brackets, support spacing and installation approach. Ceiling-mounted bay tracks often provide the cleanest finish.
Heavy or lined curtains place more load on the bends and brackets. Stronger tracks or additional fixing points may be required.
The track must sit far enough away from handles, sills, radiators and walls so the curtains can move and hang freely.
Curtains need somewhere to sit when open. Limited side-wall space may affect track length, curtain split and final stack position.
Accurate planning
A bay track should sit at a consistent and practical distance from the window where possible. Variations in the walls, ceiling line or bay projection may require careful positioning.
Corners must be smooth enough for the selected runners and curtain hooks. Tight bends can create resistance, particularly with heavy curtains or linked wave runners.
The final design should also consider where the curtains will stack when open, how the window handles operate and whether radiators or furniture restrict the curtain path.
Common questions
Often yes, provided the track system can be shaped or joined around the bay and the runners can travel through the corners. Very sharp angles or unusual structures may require separate sections.
Ceiling mounting can create a clean finish and may make it easier to follow the bay shape. The ceiling must provide suitable structural support for the track and curtain weight.
Sometimes. The bend radius, runner system, wave spacing and available stack-back space must all be suitable. Tight corners can affect the formation and movement of wave folds.
Some made-to-shape systems may require a physical or measured template. Others can be prepared using accurate dimensions and angles. The required method depends on the selected track.
