Throw vs Blanket: What's the Difference?
Short answer. In the throw vs blanket question, the difference is size and job. A throw is a smaller, ornamental layer, usually 120×150 to 150×200 cm, made to drape over a sofa or the foot of a bed. A blanket is sized to cover a whole bed, typically 180×230 cm or larger, and tucks in.

The words get used loosely, and shops often say “throw blanket” to mean either. But a throw and a blanket are designed for different places, and buying the wrong one usually means a blanket that swamps a sofa or a throw that leaves your feet out of a bed.
Key takeaways
- A throw is usually between 120×150 cm and 150×200 cm; a bed blanket is usually 180×230 cm or larger.
- Throws are designed to be seen, with fringes, tassels, checks and textures; blankets are designed to be tucked in.
- Warmth depends on fibre, weight and weave, not on whether the label says throw or blanket.
- A large throw of 200×230 cm can cover the top of a double or king bed like a light blanket.
What is the difference between a throw and a blanket?
A throw is a small, ornamental layer for sofas, chairs and the end of a bed; a blanket is a larger, plainer layer made to cover a whole bed and be tucked in.
The name gives it away: a throw is something you throw over furniture. It is meant to be seen, so it often has a fringe, tassels, a border or a bold check, and it is sized for one person to pull over their lap. A blanket is a working bed layer. It is sized to the mattress, has bound or hemmed edges that tuck neatly under it, and usually sits under a bedspread or on top of a sheet.
“Throw blanket” is simply a throw. Most of what is sold for the living room today is a throw, whatever it is called.
How big is a throw compared with a blanket?
A throw is roughly half to two-thirds the size of a bed blanket: most throws are 130–150 cm wide, while blankets are sized to cover a mattress plus a drop of 20 cm or more each side.
| Type | Typical size (cm) | Where it goes |
|---|---|---|
| Lap throw | 115×160 to 120×150 | Armchair, one person |
| Sofa throw | 130×170 to 150×200 | Sofa, foot of bed |
| Bed-size throw | 150×220 to 200×230 | Across or over a bed |
| Single blanket | About 180×230 | Single bed, tucked in |
| Double blanket | About 230×230 | Double bed, tucked in |
| King blanket | About 260×230 | King bed, tucked in |
Blanket sizes vary between brands, so measure your mattress first. UK mattresses run from 90×190 cm for a single to 180×200 cm for a super king. Our full throw size chart goes into sofa sizes in more detail.
Can you use a throw as a blanket?
Yes, if it is big enough: a throw of 200×230 cm covers the top of a double or king bed, and a 150×200 cm throw covers a single.
It will not tuck in the way a blanket does, because it is shorter at the sides, but laid over the duvet it adds a warm layer. A smaller sofa throw is better folded across the foot of the bed; our guide on how to lay a throw on a bed shows the method. Going the other way, a bed blanket on a sofa tends to look heavy and bunched, because there is too much cloth for the space.
Is a blanket warmer than a throw?
Not by definition; warmth comes from the fibre, weight and weave, so a dense pure wool throw can be warmer than a thin cotton blanket.
Wool is a warm fibre for its weight. Multi-layer cotton muslin and gauze trap air between their layers, so they feel warm but stay light. A single layer of thin cotton or a loose open weave adds the least. If the bed itself feels too cold or too warm, the duvet is the thing to change; see our guide to choosing a duvet tog.
Throw vs blanket: which one do you need?
Choose a throw for a sofa, an armchair or the foot of a bed; choose a blanket, or a bed-size throw, if you want a layer that covers the whole bed.
If you only want one piece that does both, a bed-size throw is the most flexible: folded in thirds it sits on a sofa arm, and opened out it covers a bed. Many people end up with a throw in the living room and another at the end of the bed, which is also why a throw is an easy present; see choosing a throw as a gift. If you are dressing a bedroom from scratch, our guide to sizing a rug under the bed uses the same mattress measurements.

Frequently asked questions
Why is it called a throw?
Because it is made to be thrown over furniture, such as the back or arm of a sofa, a chair or the end of a bed. The name describes how it is used rather than any particular fibre, weave or size.
Is a throw blanket the same as a throw?
Yes. “Throw blanket” and “throw” mean the same thing: a smaller, ornamental blanket for sofas, chairs and the foot of a bed. Shops use both names, and sizes under about 150×200 cm are throws whatever they are called.
What is a bedspread, and how is it different from a throw?
A bedspread is a large top cover that reaches down the sides of the bed, often to the floor, and goes over the duvet or blankets. A throw is smaller and covers only part of the bed, usually the foot.
Can a throw replace a duvet in summer?
For some people, on warm nights, a light cotton throw or a top sheet is enough on its own. Most throws are narrower than a duvet, so choose a bed-size throw of 200×230 cm if you want it to cover two people.
What size throw covers a double bed like a blanket?
A double mattress is 135×190 cm, so a throw of about 200×230 cm covers the top and hangs over both sides. A 150×200 cm throw covers the surface of a double bed but leaves little overhang at the sides.
Are throws machine washable?
Many are. Cotton and linen throws usually wash at 30°C on a gentle cycle. Wool and wool blends are best aired, spot cleaned, or hand washed in cool water with wool detergent. Always check the care label before washing.
