TL;DR — Which Should You Choose?
There’s no single winner. For kitchens and bathrooms, blinds are the practical choice — moisture-resistant, easy to clean, and unobtrusive. For living rooms and bedrooms, curtains bring warmth and character, though a Roman or blackout blind works just as well in the right space. For the best of both, layer the two at the same window. The decision usually comes down to the room, the window size, and how you live.

Curtains and blinds both do the same job — cover your windows — but they do it in very different ways. Curtains bring warmth, softness, and a certain sense of occasion to a room. Blinds offer precise light control, a cleaner profile, and often suit smaller or more practical spaces far better. Neither is the right answer for every room, and in many homes, you’ll want both. The real question isn’t which one wins — it’s which one is right for each window in your home.
At Aquarius Interiors, we sell both, make both in-house, and fit both every day. So when customers ask us “should I go for curtains or blinds?”, our answer is always the same: tell us about the room first
Does Window Size Make a Difference?
Yes, significantly. Window size affects which product will work practically, not just aesthetically.
Small rooms and tight recesses
In a compact room — a box bedroom, a small bathroom, a narrow hallway — space at the window becomes precious. A roller blind or Roman blind fitted inside the recess uses no wall space at all. Curtains, on the other hand, need room either side of the frame to “stack back” when open. If that space isn’t there, even a beautifully made curtain will partially block the glass when drawn back, eating into the natural light.
In rooms where light is already limited, that’s worth thinking about carefully.
Large windows, bay windows, and French doors
Larger windows tend to suit curtains well — particularly floor-length styles hung from a pole or track that extends beyond the frame. This approach frames the window rather than just covering it, and creates a sense of height and generosity that blinds struggle to match at scale.
Bay windows are a specific case we handle regularly. Getting the geometry right — whether that’s a curved bay pole, a track that follows the shape, or individual blinds fitted into each recess — makes all the difference. We completed a bay window project in 2025 working with Rossi Studios, and the fitting approach completely changed how the room felt. If you have a bay window, it’s worth speaking to someone who has actually fitted them before committing to either option.
Vertical blinds are worth considering for very wide windows or patio doors — they slide fully aside and control light angle without restricting the opening.
Which is Better for Blocking Light?
Full blackout: curtains vs blackout blinds
For complete darkness — blackout, not just low light — curtains with a blackout lining are hard to beat. A well-made pair with the right lining and a pelmet or returns at the side will cover more of the wall and leave fewer gaps than a blind in the same window. This is particularly relevant for children’s bedrooms; we’ve written about this in detail in our guide to blackout curtains for children.
That said, blackout blinds — whether roller, Roman, or vertical — have improved significantly. Our blackout roller blinds use tightly woven, premium fabrics that dramatically reduce light ingress when fitted precisely to the recess. The key word is “fitted precisely”: a blind that sits inside a deep recess with minimal side gaps performs far better than one on a shallow reveal.
Light filtering without full blackout
This is where blinds genuinely excel. A Roman blind, a Venetian, or a Pirouette shade from our Luxaflex® range lets you dial the light — soften the glare in an afternoon sun while keeping the room bright. Curtains are more binary: open or closed. Blinds give you the in-between.
The bedroom vs home office distinction
The bedroom is about sleeping, which often means complete darkness. The home office is about working — you want to reduce screen glare without sitting in a darkened room all day. For offices and workspaces, a quality roller blind with a light-filtering fabric, or a Venetian where you can angle the slats, is often more practical than a curtain you’d end up leaving half-open anyway.
Warmth, Insulation, and Energy Efficiency
The Energy Saving Trust estimates that up to 40% of a home’s heat is lost through windows. What you put on them genuinely matters.
The radiator problem with thermal curtains
Thermal curtains are excellent at retaining warmth — provided they’re hung correctly. Something we see regularly in our fitting work: floor-length curtains that fall in front of the radiator beneath the windowsill. The curtain traps the heat between the fabric and the wall, and it escapes straight out through the glass rather than circulating into the room. If your radiator sits under your window, this is a real consideration — either choose a blind, or opt for curtains with a high sill-length hem.
Insulation-first blinds
Luxaflex® Duette® shades are the most thermally effective blind we offer. Their honeycomb cellular construction traps a layer of air between the fabric and the glass, acting as an insulating barrier in both directions — keeping warmth in during winter and heat out during summer. They sit fitted to the window, so there’s no air gap around the sides and no risk of covering a heat source.
For a straightforward thermal blind with less complexity, Roman blinds with a thermal interlining are a solid choice.
Which genuinely saves more heat?
There’s no single answer — it depends on the fitting, the fabric, and the window. What we can say from experience is that a correctly hung blind fitted to the recess performs consistently well. A correctly hung curtain with proper blackout or thermal lining performs equally well — sometimes better, particularly on older windows with draughty frames where the additional coverage area of a curtain helps.
Which Room Are You Dressing?
Here’s how we tend to advise customers, room by room:
| Room | Our Recommendation | Why |
|---|---|---|
| Living room | Curtains, or curtains over blinds | Warmth, texture, the aesthetic anchor the room needs |
| Bedroom | Blackout curtains or Roman blackout blinds | Sleep quality; curtains win on total blackout, Roman blinds suit smaller spaces |
| Kitchen | Roller blind or Venetian | Wipe-clean fabrics, moisture resistance, no trailing fabric near the hob |
| Bathroom | Roller or Venetian (vinyl/aluminium) | Moisture-resistant materials; curtains risk mould in humid rooms |
| Home office | Light-filtering roller blind or Venetian | Glare control without full blackout; easy one-handed operation |
| Patio doors | Vertical blinds or long curtains | Vertical blinds slide aside fully; curtains work if there’s space |
| Nursery / child’s room | Blackout blind or blackout curtains with cordless/motorised mechanism | Safety first; darkness for daytime naps |
Curtains and Blinds Together — Can You Use Both?
Yes, and it’s one of the most effective approaches we see in practice.
Why layer curtains over blinds?
The blind does the functional work: precise light control during the day, privacy in the evening. The curtains do the decorative work: they frame the window, add softness and warmth to the room, and provide an extra layer of insulation when drawn at night. Many of our customers have both fitted at the same window — and once they do, they rarely go back.
How to hang them together
The blind fits inside the recess, or on the frame. The curtains hang from a pole or track mounted above and beyond the window frame. The two don’t compete; they sit in different planes. The curtains can remain open all day if you want, used purely as a visual feature, while the blind handles the light. Or close both at night for the best possible blackout and insulation.
Which rooms benefit most from layering?
Living rooms and master bedrooms are the obvious candidates. The layered approach suits rooms where you’re investing in the overall feel of the space, not just the window covering. It’s also particularly effective in older properties where windows have character but aren’t particularly well-insulated — the combination does more than either product could alone.
Practical Considerations Before You Buy
Child and pet safety
All blinds we supply comply with the Make it Safe child-safety standard. Corded blinds carry a real risk in homes with young children, and UK safety regulations have tightened significantly in recent years. Our strong recommendation for any home with children or pets is to choose a cordless or motorised option. Electric and motorised blinds are fully cordless — controlled by remote, app, or wall switch — which removes the hazard entirely. Motorised options are also available for curtains via an electric rail, with the same benefits.
We’ve fitted nursery blinds for many customers over the years, including those who’ve come back specifically for the cordless upgrade when a baby arrived.
Cleaning and maintenance
Blinds are generally easier to maintain day-to-day. A roller blind can be wiped clean; a Venetian blind can be dusted slat by slat or vacuumed with an upholstery attachment. Curtains require more effort — they need occasional machine or dry-cleaning depending on fabric, and heavier interlined pairs aren’t always practical to launder at home. Warren has published a full blind maintenance guide with cleaning routines by material if you want the detail.
For kitchens and bathrooms specifically, curtain fabric is susceptible to moisture, grease, and odour over time. A vinyl or aluminium Venetian in those rooms is the practical choice.
Renters and no-drill options
If you’re renting and can’t drill into walls or frames, roller blinds fitted with a tension mount or no-drill fitting are the simplest solution. Speak to us about the options — not every situation requires screws, and we’ll tell you what’s feasible for your window type.
Longevity and moving home
Made-to-measure curtains are more portable than blinds. A pair of curtains can often be rehung in a new home — adjusted in length if needed, and rehung on a new pole. A made-to-measure blind, by contrast, is sized exactly to one window. If you’re planning to move in the near future, or if you’re furnishing a rented property temporarily, curtains may be the more practical long-term investment.
What About Shutters?
Shutters sit outside the curtains vs blinds debate entirely, but they’re worth a mention because the question comes up often. Luxaflex® shutters — both real wood and faux wood — offer excellent light control, strong insulation, and a clean finish that needs very little maintenance. Faux wood shutters are moisture-resistant, making them a strong choice for bathrooms and kitchens. They’re a premium option with a higher upfront cost, but in the right room they’re genuinely the best product for the job.

| Best for living rooms / bedrooms | Yes | Yes — particularly Roman and blackout blinds |
Frequently Asked Questions
Are curtains warmer than blinds?
Not necessarily. Thermal curtains hung correctly — clear of the radiator, with a blackout or thermal lining — perform very well. But Luxaflex® Duette® honeycomb shades are engineered specifically for insulation and are hard to beat on thermal performance alone. The quality of the fitting matters as much as the product choice.
Which is cheaper — curtains or blinds?
Made-to-measure blinds are generally more affordable than made-to-measure curtains at a comparable quality level. Ready-made curtains from a high-street retailer can be very cheap, but they’re not sized to your window and often lack the lining quality that makes the difference. Both represent long-term value when made correctly.
Can you use curtains and blinds together?
Made-to-measure blinds are generally more affordable than made-to-measure curtains at a comparable quality level. Ready-made curtains from a high-street retailer can be very cheap, but they’re not sized to your window and often lack the lining quality that makes the difference. Both represent long-term value when made correctly.
Can you use curtains and blinds together?
Yes, and many of our customers do. The blind sits inside the recess and handles day-to-day light control; the curtains hang from a pole outside the frame and add warmth, privacy, and style. The two products work in different planes and complement rather than compete with each other.
What’s better for a bedroom — curtains or blinds?
Both work well. Curtains with a full blackout lining offer the most complete light exclusion, particularly if fitted with a pelmet or returns. A Roman blind with blackout fabric is a good choice for smaller bedrooms where curtain stack-back would eat into the usable space. For the best result, some customers use both.
Are blinds better for kitchens and bathrooms?
Yes, for most kitchens and bathrooms. Fabric curtains are susceptible to moisture, cooking residue, and the humidity that builds up in these rooms over time. Vinyl or aluminium Venetian blinds, or roller blinds with a wipe-clean finish, handle those conditions far better and are much easier to keep clean.
What’s the safest option for homes with children?
Any cordless or motorised option. All blinds we supply meet the Make it Safe child-safety cord standard, and we strongly recommend motorised or cordless mechanisms for any home where young children are present. Electric blinds controlled by remote or app are fully loop-free — the cleanest and safest solution available.
