An Ideal Home report comparing blackout curtains and blinds says neither option guarantees a completely dark bedroom: light can enter around the edges unless the window is closely sealed. Curtains offer a softer look and can help cover gaps, while blinds provide more adjustable light control and often need less cleaning. For the strongest light reduction, the experts cited recommend layering a blackout blind with blackout-lined curtains and sealing gaps at the top and sides.

An Ideal Home report comparing blackout curtains and blinds says neither option guarantees a completely dark bedroom: light can leak through gaps around the window dressing, making the fit as important as the product. For more options, see these blackout curtains and blinds. The experts consulted describe curtains as a way to soften a room and cover more of the window, while blinds offer a streamlined look and more adjustable control over light.

Curtain-maker Pat Giddens told Ideal Home that achieving complete darkness is difficult without a fully sealed system. Even small openings around a curtain or blind can admit light, she said. With blinds, light may pass around the sides or through gaps at the top and bottom; Giddens recommends making a roller blind wider and taller than the window opening to reduce those gaps. Cassette blinds with a headrail and side channels can enclose the covering more closely.

Victoria Robinson, product manager at Hillarys, described the main practical and aesthetic differences. Curtains typically move between open and closed positions, while blinds can be adjusted to regulate brightness, privacy and glare. Roller blinds are generally easier to dust or wipe down, she said, whereas curtains and Roman blinds, being fabric, may need more careful cleaning. Both types can be motorised, including for scheduled opening and closing.

The report says the choice also depends on room size, layout and installation. Curtains need a pole or track and enough room to hang; a blind can be fitted inside the window opening or across its exterior. Furniture, radiators and other obstacles can affect what works. For people prioritising darkness, Giddens’s preferred setup is a blackout blind under blackout-lined and interlined curtains, with a pelmet or another way to close the top and sides; these blackout window covers offer further options.

How Fit Changes Bedroom Darkness

The comparison matters because “blackout” does not necessarily mean total darkness. A product’s material may block light through its surface, but light can still enter around its edges. Buyers focused on sleep or shift-work conditions may get less benefit than expected if they choose a covering without accounting for gaps, window shape and installation.

The report also shows that maximum light reduction comes with trade-offs. Layered curtains and blinds can add cost, bulk and installation work, while a single blind may suit a smaller room or someone seeking adjustable light and a less prominent window treatment. The report does not establish that either option improves sleep; it compares their practical ability to manage light and their appearance.

The Experts’ Comparison Criteria

The Ideal Home report assesses curtains and blinds across four areas: light blocking, appearance, upkeep and fitting. It does not present a controlled test or numerical comparison of how much light each product blocks. Its conclusion is based on advice from industry specialists, so performance will vary with product design and the specific window.

Season also affects the experience, Giddens told the publication. Brighter summer sunlight, earlier sunrises and later evenings can expose gaps that are less apparent in winter. The article also points to Roman blinds as a fabric option with a more compact profile, and to layering a blackout roller blind with curtains as a way to combine light control with a softer finish.

“Complete blackout is exceedingly difficult to achieve unless you have a fully sealed system.”

— Pat Giddens, curtain-maker, as quoted by Ideal Home

What the Comparison Cannot Establish

The report provides no measured light-blocking results for specific curtains, blinds or installation systems, and it does not identify a single best option for every bedroom. It is not clear how much darkness any named product achieves, because the supplied material gives no model-by-model testing, measurements or standardised comparison. The article also does not provide prices or quantify the added cost of a layered setup.

Actual results will depend on window dimensions, the size of gaps, the covering’s construction and how it is installed. The report does not establish that blackout treatments produce better sleep. Its recommendations concern light management, appearance and practical use; individual needs and room conditions may differ.

Measure Before Choosing a Treatment

The next step for shoppers is to assess the window and surrounding space before buying. Robinson advises measuring for the actual curtain pole or track and drop, rather than relying only on window dimensions. For blinds, buyers should decide whether the fitting will sit inside the opening or span the outside, then account for radiators, furniture and other obstructions.

Anyone seeking the darkest practical result can compare a well-fitted blind with a layered arrangement that closes gaps at the top and sides. The report advises checking care labels before cleaning fabric coverings and seeking professional advice if measurements or fitting requirements are uncertain. No further testing or follow-up findings are included in the supplied source.

Key Questions

Are blackout curtains or blackout blinds better at blocking light?

Neither is automatically better, according to the experts quoted by Ideal Home. How closely the covering fits the window and whether light can leak around its edges affect the result.

Can blackout curtains or blinds make a bedroom completely dark?

Not necessarily. Curtain-maker Pat Giddens says complete blackout is difficult without a fully sealed system, because even small gaps can let light into the room.

What setup does the report recommend for maximum darkness?

Giddens’s preferred approach is a blackout blind beneath blackout-lined and interlined curtains, with a pelmet or another method of closing gaps at the top and sides. The report does not say this arrangement is necessary for every bedroom.

Are blackout blinds easier to maintain?

Robinson says roller blinds are generally easier to dust or wipe down. Fabric curtains and Roman blinds can require more care, and the report advises checking the product’s cleaning instructions.

What should I measure before buying?

For curtains, measure the pole or track and the required drop. For blinds, decide whether the fitting will sit inside or outside the window opening. Also check nearby furniture, radiators and other obstacles.
