What size heated blanket do you need?
Blanket sizes are not mattress sizes, and the gap between them is different at every bed size. Here are the numbers the makers publish, and what they mean for drape.
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 queen heated blanket is 84 by 90 inches on four of the brands we track, and a queen heated mattress pad is 60 by 80 - about 24 inches of difference across the bed, because a blanket drapes and a pad is fitted. Buy by what the product sits on, not by the bed name. For a queen bed the pick is the Westinghouse flannel queen at 84 x 90 inches and a published 100 W, the lowest rated draw any queen here stands behind.

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.

Where it falls short
- One controller only, so the whole bed runs at one temperature

#ad how we are funded - price as of November 2, 2026
The only king-size blanket we found with a stated wattage. Dual 110 W controllers, 290 GSM flannel over sherpa.
Where the wattage comes fromBedsure states 120V AC at 60Hz with dual 110W controllers. Both sides at full is 220W; one side alone is 110W. Notably that is the same figure Bedsure prints for its queen, so the king is bigger but the controllers are rated the same.

130 W published, the highest single-controller figure on this site, on a blanket smaller than the queen. Worth knowing before you buy.
Where the wattage comes fromBedsure states "a power rating of 130W" at 120V AC, 60Hz. It is a single-controller full, so 130W is the whole blanket. That it draws more than the same brand's 110W-per-side queen controller is a real quirk of the range, not an error on our part.

One of the very few listings in this category that publishes the temperature its settings actually deliver: 87 to 126 F.
Where the wattage comes fromNo wattage published. Sealy does, unusually, publish the temperature range the ten settings cover (87-126 F), which is a different and genuinely useful number, but it is not a figure you can compute a bill from.

How we ranked these
- Every dimension here is quoted from a manufacturer's own listing. We did not measure anything and we did not take sizes from a generic bedding chart.
- Mattress dimensions come from the heated mattress pads themselves. A pad is a fitted product, so the size its maker states is the mattress it is built to fit. That keeps every number on this page sourced to a product listing rather than to folklore.
- The pick at each size is the one that publishes most, wattage first, because a blanket you can cost before you buy it is the one we can rank honestly.
- Not ranked on fit in your bed, warmth or feel. We have not handled these.
We have not handled these products and we do not claim to have. The full method, including the rubric weights and what we refuse to claim, is on our methodology page.
The published dimensions, by size
This is the table the rest of the page explains. Every figure is quoted from a listing we track; where the makers disagree, both numbers are shown.
| Bed size | Mattress, per the pads | Blanket, per the listings | Wider by | Longer by |
|---|---|---|---|---|
| Twin | 39" x 75" | 62" x 84" | 23" | 9" |
| Full / double | 54" x 75" | 72" x 84" | 18" | 9" |
| Queen | 60" x 80" | 84" x 90" | 24" | 10" |

Mattress column from the heated mattress pads in our registry (Bedsure twin 39 x 75, Bedsure full 54 x 75, Sunbeam and Serta queen 60 x 80, Serta and Valthie king 78 x 80, five brands at California king 72 x 84). Blanket column from the blanket listings (Sealy and Sunbeam twin 62 x 84, Bedsure full 72 x 84, Bedsure, Westinghouse, Sealy and Serta queen 84 x 90, Bedsure and Sunbeam king 90 x 100). Checked 2026-08-31 and re-verified 2026-10-23.
Blanket sizes are not mattress sizes
This is the single thing that causes a wrong order. A queen heated mattress pad and a queen heated blanket share a word and nothing else: the pad is 60 by 80 inches and the blanket is 84 by 90. They are built for different jobs. The pad has to fit the mattress exactly, because it is a fitted sheet with a heating element in it. The blanket has to cover you and then hang over the sides, because that is what a top layer does.
So when a listing says queen, read what the product is before you read the size. A pad sized to the mattress is correct. A blanket sized to the mattress would be unusable. The choice between the two formats, costed, is on heated blanket vs heated mattress pad.
How much drape each size actually gives you
The spare inches are not distributed the way most people assume, and the king is the surprise.
- Queen. 84 x 90 against a 60 x 80 mattress. Lay the 90-inch edge across the bed and you get 15 inches per side with 4 inches spare at the foot. Lay the 84-inch edge across and it is 12 inches per side with 10 spare lengthways.
- King. 90 x 100 against a 78 x 80 mattress. The 100-inch edge across gives 11 inches per side and 10 spare lengthways; the 90-inch edge across gives 6 inches per side and 20 spare. A king blanket has the least overhang per side of any bed size here.
- Full. 72 x 84 against 54 x 75. 9 inches per side on the 72-inch axis, which is the tightest drape in the table.
- Twin. 62 x 84 against 39 x 75. 11 to 12 inches per side, and 9 inches spare lengthways.
The transposed dimensions, which are not a mistake
Read enough listings and you will notice the same size written two ways. Bedsure, Westinghouse, Sealy and Serta state their queen as 84 x 90. Sunbeam and Beautyrest state theirs as 90 x 84. At king, Bedsure and Sunbeam say 90 x 100 and Westinghouse and Beautyrest say 100 x 90.
It is the same rectangle. What differs is which number the brand calls the width, and no brand we track prints a diagram to settle it. The practical consequence is small but real: you decide the orientation when you put it on the bed, and the two orientations give noticeably different overhang, as the list above shows. If you want maximum coverage at the sides, put the longer number across the bed.
Throws are effectively one size
Of the fourteen heated throws in our registry, twelve state exactly 50 by 60 inches. The exceptions are the Westinghouse foot-pocket throw at 50 x 62 and the Beautyrest Zuri at 50 x 70. Wearables run a little longer again, at 50 x 70 with an 18-inch foot pocket on both the Sealy and the Westinghouse.
So there is no size decision to make on a throw. There is a format decision: flat throw, foot-pocket throw, or wearable. And a 50 x 60 throw does not cover a bed. If that is what you want it for, you want a blanket.
The two sizes nobody makes
California king. We track five California king heated mattress pads - Valthie, Beautyrest, Serta, Sealy and Bwarm, all at 72 x 84 inches - and no California king electric blanket from any brand. If you have a California king and want a top layer, a king blanket at 90 x 100 is longer than the 84-inch mattress and 12 inches wider than it, so it covers; it is simply not sold under that name. The pad is the format built for this bed, and the reason a king pad will not substitute for a California king one is on California king heated mattress pads.
Twin XL. Nobody in our set publishes one. A twin heated blanket is 62 x 84 inches, and a twin XL mattress is five inches longer than a twin - so the standard twin blanket's 84-inch length still clears an 80-inch twin XL mattress by four inches. It is tighter than ideal, and it is not nothing.
What to check on the listing before you order
- 1Find two numbers in inches, not a bed name. If the listing only says queen, you do not know what you are getting, and in this category the bed name alone is genuinely ambiguous between a blanket and a pad.
- 2Confirm the product format. Blanket on top, throw on a sofa, mattress pad underneath. The size that is correct for one is wrong for the others.
- 3For a pad, read the pocket depth as well as the size. Pads in our set state 15 to 18 inches of skirt, and one states elastic that fits up to 21. A pad that is the right length and the wrong depth will not stay on.
- 4For a blanket, check the controller count against the size. Several brands ship two controllers at queen and above and one below it; Biddeford and Beautyrest both state exactly that. The same product name behaves differently at different sizes - see dual control or single control.
- 5Check the cord reach for the bed you actually have. A king bed puts the controller further from the socket than a twin does, and cord length is published far less often than size is.
Which size costs more to run
Bigger blankets draw more, where the maker publishes a number at all. Bedsure is the only brand that does across its range, and its own figures scale with size: 100 W on the throw, 130 W at full, and dual 110 W - 220 W with both sides up - at queen and king.
| Run time | kWh | Cost | Working |
|---|---|---|---|
| 1 hour | 0.13 | 2 cents | 130 x 1 / 1000 x 0.1834 |
| 4 hours (an evening) | 0.52 | 10 cents | 130 x 4 / 1000 x 0.1834 |
| 8 hours (a night) | 1.04 | 19 cents | 130 x 8 / 1000 x 0.1834 |
| 30 nights at 8 hours | 31.20 | $5.72 | 130 x 240 / 1000 x 0.1834 |
| A 120-night winter at 8 hours | 124.80 | $22.89 | 130 x 960 / 1000 x 0.1834 |
Rate: US Energy Information Administration, Electric Power Monthly, Table 5.3 (June 2026): 18.34 cents per kWh, average US residential. Retrieved 2026-08-31.
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.
That is the whole size-to-cost relationship in this category, and it exists only because one brand publishes the numbers. Everyone else leaves you to assume. The full ledger of who publishes what is on the watts, by model.
Questions people actually ask
- What size is a queen electric blanket?
- 84 by 90 inches on the Bedsure, Westinghouse, Sealy and Serta listings we track. Sunbeam and Beautyrest state the same rectangle as 90 by 84. A queen heated mattress pad is a different product at 60 by 80 inches, which is the mattress size rather than the blanket size.
- What size is a king electric blanket?
- 90 by 100 inches per Bedsure and Sunbeam; Westinghouse and Beautyrest state 100 by 90. Against the 78 x 80 king mattress their own brands' pads are built for, that is 12 inches wider and 20 inches longer.
- What size is a heated throw?
- 50 by 60 inches. Twelve of the fourteen heated throws in our registry state exactly that, with the Westinghouse foot-pocket throw at 50 x 62 and the Beautyrest Zuri at 50 x 70 as the exceptions.
- Is a queen electric blanket bigger than a queen mattress?
- Yes, by about 24 inches across and 10 along. That is deliberate: a blanket has to hang over the sides, so it is sized for drape rather than for the mattress. A heated mattress pad is the opposite - it is sized to the mattress exactly, because it is fitted.
- Can I use a king electric blanket on a California king bed?
- Dimensionally it covers: a king blanket is 90 x 100 inches and a California king mattress is 72 x 84. No brand we track sells a California king electric blanket, so a king blanket is the only top-layer option at that bed size. A king heated mattress pad is a different matter and genuinely does not fit.
- Do they make a twin XL electric blanket?
- Not in our set. A standard twin heated blanket is 62 by 84 inches, so its length still clears an 80-inch twin XL mattress by four inches. It is a tighter fit than a true twin XL product would be.
