Bay Window Curtains

Bay windows need the hardware to follow the architecture. The key question is how the track or pole negotiates the bay, and where the curtains stack when open.

Start with the shape of the bay

Bays come in many forms: angled, square, curved, shallow or deep, with sills, radiators and window seats to work around. The curtains need to follow that shape, draw smoothly around the corners and stack somewhere sensible when open. The hardware decision comes first; the fabric follows.

Track or pole

A correctly specified track can usually follow a bay more smoothly than a decorative pole, particularly where the bends are tight or the curtains are heavy. Tracks can be bent to the angles of the bay and fixed to the wall or ceiling.

A bay pole, jointed at each angle, suits rooms where you want visible decorative hardware. Curtains on a bay pole draw around the joints, so the pole and rings must be designed for it. See curtain tracks and poles.

One pair or several

Options include:

a single pair that draws right around the bay and stacks at each end
several curtains, one per section of the bay, each with its own stack
dress curtains at the ends of the bay, with blinds or shutters doing the everyday work

The right answer depends on the size of the bay, the wall space either side and how you use the room.

Stack, returns and projection

When a single pair stacks at the ends of the bay, it keeps the glass clear. Curtains stacking in the angles can block light and views. We also plan returns at each end and projection to clear sills, window boards and handles.

Radiators and length

Many bays have a radiator beneath the window. Full-length curtains in front of a radiator can trap warm air behind them, so sill-length curtains, or floor-length curtains that stay open during the day, may suit better. Window seats bring the same question.

Layering

Bay curtains combine well with bay window blinds, bay window shutters, Roman blinds or sheers. Each layer needs its own space, so we plan the fixing positions together. See layered window treatments.

Heading and motorisation

Pencil pleat, pinch pleat and wave headings all work on bending tracks. Motorisation in a bay is possible on selected systems, depending on the number and angle of the bends.

Measuring and fitting

We measure each section and angle of the bay, the ceiling line and the fixing surface, and check radiators and sills. Everything is confirmed at your free home survey.

Honest suitability

Is it right for your window?

Every recommendation comes with a reason. Where something else would serve you better, we say so — and suggest what to consider instead.

Where this works well

Bays with a bent track Recommended
A track follows the angles smoothly and lets curtains draw right around.
Period bays with a bay pole
A jointed pole makes the hardware a decorative feature.
Worth knowing: The pole and rings must be designed to pass the joints.
Layered with blinds or shutters Recommended
Blinds or shutters handle daily light and privacy while curtains add softness.
Worth knowing: Both layers need space, so fixings are planned together.
Bays with radiators beneath With conditions
Sill-length curtains or dress curtains still frame the bay well.
Worth knowing: Full-length curtains over a radiator can trap warm air; confirmed at survey.
Motorised bay curtains Specialist survey
Selected track systems can be motorised through bends.
Worth knowing: Depends on the number and angle of the bends; confirmed at survey.

Where we’d suggest something else

Small bays with deep sills or window seats
Why: Curtains have to hang in front of the sill and can block the light.
The limitation: Stacked curtains can take up much of a small bay.
Consider instead: Bay window shutters
Maximum darkness in a bay
Why: Light leaks at every angle and where curtains meet.
The limitation: Curtains alone struggle to darken a bay fully.
Consider instead: Bay window blinds

Fabrics and linings

Bay curtains can use any lining. Heavier constructions need the track or bay pole, and its supports, specified to match.

Standard lining is a separate backing layer sewn behind the face fabric. It protects the fabric from direct sun, adds body and helps the curtain hang and fold consistently.

Blackout lining is designed to stop light passing through the curtain itself. It does not make a room completely dark: light can still find its way around the edges, above the track or pole, beneath the hem and where the curtains meet.

Interlining is a soft layer placed between the face fabric and the lining. It adds weight, fullness and a more insulating construction, and gives many fabrics a richer drape.

The exact fabrics and linings available, and how they behave together, depend on the fabric you choose. We confirm the construction at your consultation.

Tracks, poles and operation

Bay curtains usually run on a bent track or a jointed bay pole. The main ways to operate them:

Hand-drawn: the simplest option, and quiet in use. Suits most headings on poles and tracks.
Wands: a slim rod clipped to the leading edge, so you draw the curtain without handling the fabric. No cords involved.
Cord-drawn tracks: a continuous cord opens and closes the curtains. Any looped cord must be held taut by a tensioner or safety device fixed to the wall.
Motorised tracks: available on selected track systems, with control options that depend on the system chosen. Motorisation removes operating cords altogether.

Child safety

Where a curtain track is operated by a looped cord, the loop must be held taut by a cord tensioner or safety device fitted to the wall, so it cannot form a hanging loop within reach of children. We fit any required safety devices as part of installation.

Hand-drawn curtains and wands have no looped cords, and motorised tracks remove operating cords altogether, which makes them sensible choices for children's rooms and family homes. See our guide to child-safe window coverings.

Compared with the alternatives

Bay window blinds

A blind in each section of the bay, fitted close to the glass. More light control section by section; curtains add softness and warmth.

Bay window shutters

Made to follow the shape of the bay, with adjustable louvres for light and privacy. Often combined with dress curtains.

Layered window treatments

Curtains with blinds or shutters behind, with each layer doing its own job.

Questions we get asked

Can I have a pole in a bay window?

Yes, with a jointed bay pole designed for the angles. A track is often smoother for tight bends or heavy curtains.

Where will the curtains stack?

We plan stack positions so the curtains clear the glass and do not sit awkwardly in the angles or over radiators.

Should I have one pair or several curtains?

It depends on the size of the bay and the wall space. A single pair keeps the stack at the ends; several curtains suit larger bays.

Can bay curtains be motorised?

On selected track systems, depending on the number and angle of the bends. We confirm this at survey.
