Drape
How readily the cloth falls into folds. Softer fabrics create fluid curtains; firmer cloths produce more structured folds.
Curtain Guides & Advice
Choosing the Right Curtain Fabric
Curtain fabric has to do more than look good on a sample card. Its weight, drape, opacity, width, pattern and compatibility with the chosen heading all influence how the finished curtains will hang and perform.
Start with the room and the finished treatment you want, then choose a fabric that works with the heading, lining and scale of the window rather than choosing on colour or pattern alone.
What Makes a Good Curtain Fabric?
A good curtain fabric is one that suits the room, the heading, the window and the way the curtains will be used. A beautiful cloth that is too stiff for the chosen heading, too sheer for the privacy required or awkward to pattern-match across a very wide window may not give the result you expect.
Weight
Weight influences body, movement and the visual scale of the treatment, but a heavier fabric is not automatically better.
Opacity
Decide whether you want filtered daylight, daytime privacy, general light reduction or a blackout-lined treatment.
Scale
Consider the size of the pattern, the size of the window and how much of the motif will be visible once the fabric is pleated.
Order a sample and view it at the window.
Colour, texture, opacity and sheen can look very different vertically at full height than they do on a small sample laid flat on a table.
Drape & Weight
Fabric construction and weight affect the size and softness of the folds. A sheer voile behaves very differently from linen, a medium-weight woven cloth or a dense velvet, even when all four are made to the same finished size.
Lightweight fabrics tend to form smaller, softer folds and can feel airy. Medium-weight furnishing fabrics often provide a useful balance of body and movement. Heavier cloths such as many velvets can create deeper, more substantial folds, but they also add weight to the finished treatment and hardware.
Do not judge drape from fibre name alone. Two linens, velvets or cotton blends can behave very differently because weave, finish, backing and yarn construction all matter.
Light, Opacity & Privacy
Think about what you need the curtain to do when it is closed. A sheer or semi-sheer fabric can soften daylight and provide some daytime screening, while a more opaque face fabric gives greater privacy and reduces light.
If strong room darkening is important, the lining and the way the treatment covers the window matter as much as the decorative face fabric. Light can still enter around the top, sides, bottom and centre opening even when the curtain itself uses blackout lining.
For bedrooms, separate the decorative decision from the light-control decision.
You can often choose the face fabric for colour, pattern and drape, then specify an appropriate lining for the required level of privacy and room darkening.
Lining, Blackout Lining & Interlining
Lining protects the back of the face fabric, improves opacity and can give the curtain more body. Blackout lining is used when stronger light reduction is required. Interlining adds another soft layer between the face fabric and lining, giving a fuller, more substantial treatment.
Standard lining
A conventional choice for adding body, improving the finish and reducing the amount of direct light visible through many decorative fabrics.
Blackout lining
Blocks most light passing through the curtain itself, but does not guarantee a completely dark room because light may still enter around the treatment.
Interlining
Adds softness, volume and another insulating layer. It also increases the overall weight and bulk of the finished curtains.
Unlined or sheer treatments
Appropriate where transparency, light filtration or a lighter decorative effect is part of the design.
Pattern Scale & Placement
A pattern viewed on a sample can feel very different once it is repeated across a pair of full-height curtains. Large motifs need enough visible fabric to read properly, while smaller repeats can feel busier once gathered into folds.
- Consider whether a large motif has room to be seen clearly.
- Check how the pattern will look once pleated or gathered.
- Think about the motif position at the top and lower edge.
- Allow for matching across multiple widths of fabric.
- Check whether the design has an obvious top and bottom.
- For pairs, decide how important mirrored or balanced placement is.
Fabric Width & Pattern Repeat
Standard-width furnishing fabrics normally require several vertical widths to make a large pair of curtains. Wider or railroaded fabrics can sometimes reduce the number of seams, but only where the design and construction direction allow them to be used that way.
Pattern repeat affects the length of each cut because the design needs to align from width to width. A large vertical repeat can therefore increase the amount of fabric required even when the finished curtain dimensions stay the same.
Do not calculate curtain fabric from window width alone.
Finished width, heading fullness, usable fabric width, pattern repeat, pattern direction, number of widths and the required cut drop all contribute to the final quantity.
How Common Curtain Fabrics Behave
| Fabric type | Typical curtain character | Things to consider |
|---|---|---|
| Linen & linen blends | Relaxed texture with a natural-looking drape. | Can crease and move differently according to weave, finish and blend. Always assess the actual sample. |
| Cotton & cotton blends | Versatile, available from light printed cloths to substantial furnishing fabrics. | Weight and construction vary widely, so check suitability for the intended heading and lining. |
| Velvet | Full, soft and visually rich with deeper folds. | Usually heavier than many woven fabrics and may show pile direction or pressure marks. Check the maker's handling guidance. |
| Wool & wool blends | Often soft, substantial and well suited to tailored interiors. | Composition and weave vary considerably; check care, weight and manufacturer use recommendations. |
| Sheers & voiles | Light, translucent and fluid. | Excellent for filtered daylight but provide less night-time privacy on their own. |
| Synthetics & blends | Available in a very wide range of weights, textures and finishes. | Judge the individual cloth rather than assuming behaviour from fibre content alone. |
Match the Fabric to the Curtain Heading
The heading controls the folds at the top of the curtain, so fabric and heading need to work together. A fabric that looks excellent as a relaxed pencil pleat may not necessarily be the best choice for very precise Wave folds, while a cloth that is too stiff can make some contemporary headings feel bulky.
Pencil pleat
Works with a broad range of fabrics because the gathered heading is relatively forgiving.
Pinch pleat
Benefits from cloth that can hold structured folds without becoming excessively bulky at the stitched pleats.
Eyelet
Needs enough body to form broad waves while remaining practical to slide along the pole.
Wave
Usually looks best with fabric that drapes consistently into the regular fold pattern created by the compatible track system.
See our Curtain Headings & Hems guide before finalising the curtain specification.
Sunlight, Fading & Care
Strong daylight can alter textile colour over time. The amount of change depends on the fabric, colour, dye, finish, exposure and the window itself, so no decorative curtain fabric should be treated as completely fade-proof.
For strongly sunlit windows, consider the exposure before selecting a very delicate colour or material. Lining can help protect the reverse of the decorative fabric, but the front remains exposed whenever the curtains are open.
Always follow the manufacturer's care instructions. Some fabrics are suitable for dry cleaning only, while specialist finishes, trims or interlining can affect how the finished curtains should be maintained.
Thermal & Acoustic Considerations
Well-fitted curtains can improve comfort at a window by creating an additional textile layer and reducing the sensation of draughts. Lining and interlining can make the treatment more substantial, but the result still depends on the window, coverage and installation.
Heavier, fuller curtains can also soften sound reflections within a room and may modestly reduce some noise passing through the window area. Curtains are not a substitute for acoustic glazing or building insulation and should not be described as soundproofing.
Before You Order Curtain Fabric
- Confirm the curtain heading and hardware.
- Check the fabric is recommended for curtains or drapery.
- View a sample vertically at the actual window.
- Check opacity in both daylight and artificial light.
- Confirm usable fabric width and pattern repeat.
- Check whether the design is directional or railroaded.
- Decide standard lining, blackout lining or interlining.
- Confirm care instructions and expected sun exposure.
- Have the final fabric quantity calculated for the actual curtain specification.
- Order all fabric for the pair together where practical, rather than in separate batches.
Choosing Curtain Fabric FAQs
What is the best fabric for curtains?
There is no single best fabric. The right choice depends on the room, heading, window size, required light control and the look you want. Judge the actual fabric's drape, weight and opacity rather than choosing from fibre name alone.
Can upholstery fabric be used for curtains?
Sometimes. Some furnishing fabrics are suitable for both upholstery and curtains, while others are too heavy, stiff or specially backed for a good curtain result. Check the manufacturer's recommended uses for the exact fabric.
Do thick curtains block noise?
Fuller, heavier curtains can soften sound within a room and may reduce some noise around a window, but they will not soundproof the room.
Do blackout curtains block all light?
Blackout lining prevents most light passing through the curtain itself, but light may still enter around the top, sides, bottom or centre opening. Installation and coverage are therefore important.
Should I line curtains?
Many made-to-measure curtains benefit from lining because it improves the finish, opacity and body of the treatment. Sheer or deliberately translucent curtains are obvious exceptions, and the right lining should be selected for the room and face fabric.
Does the curtain heading affect fabric quantity?
Yes. Different headings use different fullness and construction methods. Pattern repeat, fabric width and finished dimensions also affect the final quantity, so have the fabric requirement calculated from the complete specification.
