What does opaque mean?
Opaque means that light cannot pass through. An opaque object blocks the view, so you cannot see what is behind it. In fabric, opaque tights, curtains and clothing provide full coverage.
The word also has a figurative meaning: something hard to understand is called opaque, as in “opaque legal language.” In either sense, nothing gets through.
What does sheer mean?
Sheer describes fabric that is very thin and light, so you can see through it at least partly. Sheer fabrics are often loosely woven or very fine, and they tend to be soft and flowing.
Sheer fabric is commonly used for curtains, which let sunlight in while keeping some privacy during the day. It is also used for stockings, tights, dancewear and lingerie. Because sheer fabric is so light, it offers little warmth and little heat insulation.
Opaque vs sheer: how do they compare?
The main difference is how much light and detail pass through. Opaque blocks them, and sheer lets a lot through. That affects privacy, warmth and style.
Opaque gives more privacy and more warmth, and it creates a solid block of color. Sheer gives a lighter, softer, more delicate look, with less privacy and less insulation. Many products fall between the two and are labeled semi-sheer or semi-opaque.
Opaque vs sheer tights: which should you choose?
Choose sheer tights for warm weather and formal looks, and opaque tights for cold weather and full coverage. Tights are measured in denier: the lower the number, the more see-through the tights.
As a rough guide, sheer tights are around 5 to 30 denier, semi-opaque tights are around 30 to 60, and opaque tights are 40 or more, often 70 and up. Brands label these ranges differently, so check the product description. Sheer tights give a light, refined look, while opaque tights give a bolder, more solid look.
Opaque vs sheer curtains: which suits which room?
Sheer curtains suit rooms where you want daylight and a little privacy, while opaque curtains suit rooms where you want darkness or full privacy. Sheers let sunlight pass through during the day, but they offer little heat insulation.
Many people layer both: sheers for the day and thicker opaque curtains for the evening or for bedrooms. Semi-sheer curtains sit in the middle, with more privacy than sheers but more light than room-darkening panels. If you need real darkness, such as for sleep, look for blackout or room-darkening labels.
What about translucent and transparent?
Transparent lets light through clearly, so you can see detail, like clear glass. Translucent lets light through but blurs what is behind, like frosted glass. Opaque lets nothing through.
Sheer fabric usually sits between transparent and translucent: you can see through it, but the weave or fine fibers soften the view. Descriptions of fabrics are not always strict, so check photos or samples.
Does sheer have other meanings?
Yes. Sheer can also mean complete or pure, as in “sheer luck” or “sheer delight,” and it can mean very steep, as in “a sheer cliff.” If you see sheer outside a fabric context, it usually means one of those.
