An arched window has a shape worth considering before you add curtains. You might want to reveal the entire curve, leave only the upper arch exposed, or cover the whole opening when the curtains close. These choices create different mounting and coverage requirements.
Start by deciding what should remain visible in both the open and closed positions. Then check whether the room offers a practical way to achieve that result.
Choose what happens to the arch
A straight rod or track above the highest point can allow full-length panels to frame the complete window when open, where the wall and ceiling provide enough space. The curtains can then cover the arched and rectangular portions together when drawn, depending on the final arrangement.
Another approach is to mount a straight treatment below the curve, leaving the upper arch exposed. This highlights the shape even when the lower curtains are closed, but the uncovered glass still admits light and may affect privacy. Treat that as an intentional choice rather than an overlooked gap.
Check the space around the highest point
Measure the relationship between the arch, ceiling and surrounding wall. Include projecting trim, ceiling slopes or nearby beams. A tall window may leave less mounting room above its apex than an inspiration image suggests.
Ask the hardware supplier or installer to assess the mounting location and access. Do not assume a curved opening requires curved hardware, or that any standard track can follow the shape. A shaped system needs confirmation of the available components, dimensions and operation.
Map the curtain's open position
The arch can be obscured by fabric gathered too close to the glass. Mark the proposed gathering areas at the sides and compare them with the likely stack width of the selected heading and fabric.
The available wall space may differ from one side to the other. Discuss the panel arrangement before ordering, particularly if a nearby wall, cabinet or doorway limits one end. Our stack-back guide helps you separate glass width from the space needed for open curtains.
Evaluate light and privacy from useful viewpoints
View the window from the sofa, bed or table, not just from the center of the room. The upper glass can matter differently depending on outside sightlines and the room's use. Check daytime conditions and the room with its lights on after dark.
If leaving the arch exposed conflicts with the required coverage, reconsider the mounting concept before choosing decorative details. Blackout fabric across the lower rectangle cannot block light through an uncovered arch. Confirm the whole treatment's coverage rather than relying on the fabric name alone.
Measure the opening and the curtain separately
Record the window's overall height, width and the point where the curve begins. These describe the architecture. The finished curtain measurements must then follow the chosen hardware span and hanging reference.
For a shaped treatment, ask exactly what template or measurement method is required. Do not estimate the radius or profile from a photograph. Label every measurement so the window dimensions cannot be confused with the finished panel dimensions.
Keep the surrounding composition calm
A quiet fabric can let the arch remain the focal point, while a stronger texture or pattern makes the curtain itself more prominent. Compare samples against the wall and nearby furniture, both close up and from the main viewing position.
Consider the complete height of fabric, especially in a tall room. A small sample does not show how a large area of color will feel. The curtain color guide provides a useful starting point for that comparison.
Before ordering
- Decide whether the upper arch stays exposed when curtains close.
- Confirm mounting space and access above or below the curve.
- Check gathering areas, coverage and hardware operation.
- Obtain the supplier's required measurements or template instructions.
