Blinds for gable-end and triangular windows

Can you get a blind for a gable window?

Yes, in most cases. Shaped windows such as triangles, apex windows, trapeziums and arched tops can usually be fitted with a made-to-measure blind, but the choice of blind is narrower than for a square window, and every one needs to be templated or measured carefully. Not every blind type follows an angle, so the real question is which styles can be cut or built to match your shape.

What counts as a shaped window

A gable window sits in the triangular end wall of a pitched roof, so its top edge slopes on one or both sides. Related shapes include angled windows that follow a sloping ceiling, tall feature windows with a pointed top, and some conservatory ends. They look great, but they are awkward because the bottom is square while the top is not.

How the shape is captured

For a plain rectangle, three or four measurements are enough. A shaped window needs more: the height at each corner or edge, the angle of the slope, the width at several points and whether the frame is straight. Sometimes a paper or card template is the most reliable record. Walls and frames are seldom perfect, so a measure on site avoids the typical errors that creep in with a rough sketch. Our guide to measuring awkward windows shows the principle.

Blind types that can follow the angle

Pleated blinds

Pleated fabric is held between rails and can be cut to the top slope, so it is a frequent choice for angled glazing. The blind stays where you put it, and it can be opened from the top or bottom depending on the system. See pleated blinds.

Fixed or tensioned shapes

Some shaped blinds are made to sit in a frame and move along the slope. These are typically more specialist, and which ones exist depends on the supplier, so we confirm what is achievable for your window.

Shutters

Shaped shutters can be built to fit a gable, with panels cut to the angle. They are a more substantial option and suit people who want a permanent look. See shutters.

Curtains

Not always practical on a pointed top, but a curtain across the lower, square part with a separate treatment above can work. A curtain pole or track on a sloping ceiling needs careful planning.

Blind styles that rely on a straight headrail, such as standard rollers, Romans and verticals, may cover only the square lower portion unless the manufacturer offers a shaped version. We would rather say so than promise something that will not sit right.

Do you need to cover the whole shape?

Not always. Many people dress only the part that causes the problem. If glare and heat come through the upper section, that is the part to cover. If privacy matters at eye level, a blind on the lower square section may do the job, leaving the apex clear to let in light. This can be a good balance between cost, effort and appearance.

Practical questions to settle

  • Reach. Gable windows are often high. A pole, motor or remote may be sensible. See motorised blinds.
  • Heat and light. South-facing gables can get very warm, so fabric choice is worth discussing.
  • Fixing surface. Frames, plaster and timber vary, and the fixing method depends on what is behind.
  • Opening lights. If part of the window opens, the blind should not block the handle.

Where to start

Take a photo of the whole window, straight on, and note whether any part opens. Then look at our page on roof and gable blinds for the styles we can discuss. We'll confirm what is possible when we see the window itself, and we'll be honest if a particular shape limits your choices.
