Heated throw vs electric blanket
Both publish 100 watts, so per hour they cost the same. This is a sizing decision dressed up as a product comparison, and the sizing is where people go wrong.
We earn a commission on some links here, at no extra cost to you. It does not change what we recommend or the order the picks appear in. How we are funded.
A throw is 50 by 60 inches, covers one seated adult, and lives on a sofa. A bed blanket runs from 62 by 84 up to 90 by 100. Both formats publish 100 W in our set, so an hour costs the same either way. Choose on coverage, not on cost.

Both wattages quoted from the makers' own listings. Costs at $0.1834/kWh (EIA, June 2026).
The cost question, answered and dismissed
People assume a throw is cheaper to run because it is smaller. On the published figures it is not: both Bedsure throws state 100 W and the Westinghouse queen states 100 W. Same draw, quarter the area.
That is not a mistake. Wattage tracks element length and density and how the controller is configured, not fabric area. A throw with the same element draw over a smaller area heats faster and feels hotter, which is exactly what people report.
So per hour, they cost the same. In practice a throw usually costs less over a season simply because a four-hour evening is shorter than an eight-hour night. That is a usage difference, not a product one.
| Run time | kWh | Cost | Working |
|---|---|---|---|
| 1 hour | 0.10 | 2 cents | 100 x 1 / 1000 x 0.1834 |
| 4 hours (an evening) | 0.40 | 7 cents | 100 x 4 / 1000 x 0.1834 |
| 8 hours (a night) | 0.80 | 15 cents | 100 x 8 / 1000 x 0.1834 |
| 30 nights at 8 hours | 24.00 | $4.40 | 100 x 240 / 1000 x 0.1834 |
| A 120-night winter at 8 hours | 96.00 | $17.61 | 100 x 960 / 1000 x 0.1834 |

Rated wattage is the ceiling, not the average. A thermostatic blanket cycles its element on and off once the bed is warm, so an all-night bill usually lands below the rated-watt figure. We publish the rated number because it is the only one the maker stands behind, and we do not estimate a duty cycle for a blanket we have not measured.
What actually decides it
Coverage, and this is where the disappointment in this category comes from. A throw at 50 by 60 inches covers one seated adult from shoulders to ankles with nothing spare. It is closer in spirit to a dressing gown than to bedding.
- One person on a sofa: throw. It is the right size and it is easy to move.
- Two people on a sofa: a bed-size blanket draped over the pair of you. A throw each means two controllers and a cold gap in the middle.
- A bed: a bed blanket, matched to the mattress. A throw on a bed covers your torso and leaves your feet out.
- Both sofa and bed: a full or queen blanket is the versatile answer, at the cost of being awkward to carry between rooms.
The features that only exist in one format
Two things a throw cannot give you, and one a blanket cannot.
| Feature | Format | Why |
|---|---|---|
| Dual control | Bed blankets, from queen up | A throw is a one-person object |
| 12-hour timer | Bed blankets | Throws top out around 10 hours; they are built for sitting |
| Foot pockets | Throws | Only useful when you are sitting with your feet forward |
| Wearable poncho cut | Throws | A bed blanket cannot be worn |
From the products in our set, checked 2026-08-31.
The foot-pocket point is the practically useful one. If cold feet are what sent you looking, a throw with pockets solves it and a bed blanket does not, because a bed blanket is not shaped to hold your feet. Options on heated throws for cold feet.

The best-documented throw
Bedsure Heated Throw with Preheat
100 W published, a preheat cycle that steps itself down, and a 10-hour timer. The throw we would buy on the numbers.
Where the wattage comes fromBedsure states "a power rating of 100W" at 120V AC, 60Hz. Same figure as the brand's queen-size single controller, on a blanket a quarter the area, which is why a throw heats faster.
100 W x 8 h = 0.80 kWh, x $0.1834/kWh = $0.15 per night

- Model
- BS-100T
What it does well
- Published wattage, so an hour on the sofa has a computable price
- Preheat steps down automatically rather than holding peak
- Warm without power thanks to the sherpa backing
- ETL and FCC certified
Where it falls short
- 6 heat levels
- Warranty term is only in the box, not on the listing
- 50" x 60" is a one-person throw
Who this is forAnyone who wants a sofa throw and wants to know what an evening under it costs.
Skip it ifSkip it if you want to cover two people. At 50 by 60 inches it is a personal throw, not a shared one.
The lowest published draw
Westinghouse Heated Blanket, Queen
100 W stated on the listing, 10 heat levels and a 12-hour timer. The cheapest bed blanket to run of anything here that publishes a number at all.
Where the wattage comes fromWestinghouse states it directly in the first listing bullet: "a 100W, 60Hz heating blanket". This is a single-controller queen, so 100 W is the whole blanket rather than one side of it.
100 W x 8 h = 0.80 kWh, x $0.1834/kWh = $0.15 per night

What it does well
- 100 W published, the lowest figure any queen here stands behind
- 10 heat levels and a timer selectable to any hour up to 12
- Memory function, so you are not resetting it every night
- Machine washable on cold, gentle
Where it falls short
- One controller only, so the whole bed runs at one temperature
- No warranty term on the listing
- Westinghouse's other queen listings do not publish a wattage, so the figure is model-specific
Who this is forA solo sleeper, or a couple who genuinely agree on temperature and want the lowest running cost on the page.
Skip it ifSkip it if you share a bed with someone who runs hot. There is one controller and no way to split the blanket.
The verdict
Buy a throw if you are one person on a sofa and you want something you can carry to another chair. Buy a bed blanket if it is for a bed, if two people need covering, or if you want dual control.
And do not buy a throw expecting a small bed blanket. That single misunderstanding accounts for most of the dissatisfaction in this category, and it is a sizing error rather than a product failure.
Questions people actually ask
- What is the difference between a heated throw and an electric blanket?
- Size and intent. A throw is 50 by 60 inches for one seated adult on a sofa; a bed blanket runs from 62 by 84 up to 90 by 100 and is sized to a mattress. Both publish 100 W in our set, so they cost the same per hour.
- Is a heated throw cheaper to run than an electric blanket?
- Not per hour. Both formats publish 100 W in our set. A throw usually costs less over a season only because a four-hour evening is shorter than an eight-hour night.
- Can you use a heated throw on a bed?
- It will cover your torso and leave your feet uncovered. At 50 by 60 inches it is a personal item, not bedding. For a bed, buy a bed size.
- Can two people share a heated throw?
- Not comfortably. Use a full or queen electric blanket draped over the sofa instead, which covers two people from one controller.
