Fabric lampshades: silk, linen and the shape of light
A shade decides how a lamp lights a room as much as the bulb does. Here is how linen, silk and cotton differ, which shapes suit which bases and how to keep fabric shades looking fresh.
Put the same bulb under three different shades and you get three different rooms. A crisp white linen drum throws clean light down onto a table and a soft halo up to the ceiling. A pleated ivory silk shade glows like a lantern. A dark shade with a gold lining pools warm light below and leaves the rest of the room in shadow. Fabric is where a lamp finds its character.
Linen, silk and cotton
Linen has a slightly irregular weave with visible slubs, small thicker threads that give texture by day and a gently mottled glow at night. It suits relaxed, natural interiors and looks at home on ceramic, stone and wooden bases.
Silk has a fine sheen and transmits light with a soft lustre, which is why it has long been the classic choice for pleated and traditional shades. It is also the most delicate: strong sunlight fades and weakens it, and it needs careful handling. Cotton sits between the two, smooth, matt and even, easy to print and a good choice for patterned shades.
How a shade is built matters as much as the cloth. On laminated shades the fabric is bonded to a stiff backing, which gives clean lines and an even glow. Traditional hand-sewn shades are stretched over a wire frame and often have a separate , an inner layer of fabric that hides the struts and softens the light further.
Drum, empire, bell and pleats
The basic shapes are few but distinct, and each one changes where the light goes:
- Drum: nearly vertical sides, for clean, modern lines and generous light both upwards and downwards.
- Empire: narrower at the top than at the bottom, a classic profile that sends more light down than up.
- Bell: gently curved, flaring sides, traditional and soft, often made in silk.
- : a steep cone with a small top and a wide base, spreading a broad pool of light onto a table or floor.
- Pleated: fabric folded in knife or box pleats over the frame, adding rhythm and texture as light passes through the folds.
How colour changes the light
A shade is a filter. White, ivory and natural linen let the most light through and keep it close to its original colour, while oatmeal linen or ivory silk add a soft, golden tint. Strongly coloured shades tint everything that passes through them: a terracotta shade makes a lamp glow warm, a pale grey one can make the light feel cooler.
Dark and opaque shades work differently. Very little light passes through the sides, so the lamp casts strong pools up and down instead. A gold or silver liner reflects that light back and increases the output, with gold adding noticeable warmth. Such shades are dramatic in dining rooms and studies, but less helpful when a lamp needs to light the whole room.
Getting the proportions right
There are no fixed laws, but a few rules of thumb help a lamp look balanced. Measure the base from the bottom to the bulb holder, then compare.
- The height of the shade is usually about two thirds of the height of the base.
- The bottom diameter should be wider than the widest part of the base, typically by at least 2.5 cm (1 inch) on each side.
- The lower edge should hide the bulb holder and the fitting from normal viewing angles.
- On a bedside or reading lamp, the bottom of the shade should sit at about eye level when you are seated, so you see the glow rather than the bulb.
Visual weight counts as well. A heavy, curvaceous ceramic base needs a shade with presence, such as a generous empire or pleated bell, while a slim metal or glass column looks right under a neat drum. On a floor lamp, a wide drum or empire shade spreads light over a reading chair; a small shade on a tall stand tends to look lost.
Fittings and choosing a new shade
Before you buy, check how the shade attaches. A sits on a wire harp above the bulb and is held in place by a decorative finial; an uno fitter attaches below the bulb, directly onto the bulb holder; many shades in Britain and Europe use a simple ring that rests around the bulb holder. Not every shade fits every lamp, so match the fitting first and the style second.
Think about where the lamp stands. Against a wall, a shade with a white or pale interior bounces more light into the room. In the middle of a room, both inside and outside of the shade are on show, so the lining and the finish of the seams deserve a closer look.
Caring for fabric shades
Dust is the main enemy. Remove it every week or two with a soft brush, the upholstery brush of a vacuum cleaner on a low setting, or a lint roller for linen and cotton. Never soak a laminated shade: water can soften the adhesive, and the fabric may bubble or lift from its backing.
Treat silk with extra care. Brush it gently, keep it out of strong sunlight and leave stains to a specialist cleaner. Use LED bulbs, which produce very little heat, and keep the bulb well clear of the fabric: older incandescent bulbs can scorch shades, especially small or steep ones that sit close to the bulb. Treated this way, a good fabric shade will keep its colour and shape for many years.
