The watts, by model

Where these numbers come from

Every figure in the table above was read off the manufacturer's own product listing on 2026-08-31 and each row links to the listing that carries it. Nothing here is estimated, averaged, or recalled.

That matters because the alternative is what the rest of this category does. The most-cited wattage page for electric blankets publishes a single 400 W figure applied to every blanket at every size, sourced to nothing. Another assumes a rate of $0.13/kWh without saying where it came from. A third gives ranges by size (twin 50-70 W, queen 80-120 W) that our own sourced data contradicts: Bedsure's full-size blanket publishes 130 W, above the top of the range that page assigns to a queen.

The pattern in who publishes

Seven of the eight published figures come from one brand. That is worth stating plainly because it changes how you should read the table.

The Westinghouse case is the most instructive. Its queen-size flannel blanket states 100 W in the first listing bullet. Its king, its throws and its car blankets state nothing. Same brand, same category, different listings. So this is a listing-copy decision rather than a company policy, which suggests the information exists and simply is not being surfaced.

What the missing figures mean for you

If you own or are considering one of the 21 products with no published wattage, there are two honest options and neither of them is an estimate from us.

1. 1Look at the blanket itself. Many appliances carry a rating label on the controller, the plug or a sewn-in tag even when the listing does not repeat it. If there is a label, that is the manufacturer's own figure and it beats anything published online.
2. 2Measure it. A plug-in energy monitor costs about $20 and reads actual draw in watts. Plug the blanket into it, set it to the level you use, and read the number. That is a measurement of your blanket rather than a category average, which makes it better than anything on this page.

Reading the table honestly

Three caveats on our own numbers, because a data page that does not state its limits is not much better than one with no sources.

• Rated watts is a ceiling. A thermostatic blanket cycles its element off once the bed is warm, so real consumption over a night lands below the arithmetic, often well below. We publish the rated figure because it is the only number the maker stands behind and because it bounds your bill from above.
• Dual-control figures are the sum of both controllers. Bedsure's 220 W queen is 110 W per side. If only one of you uses the heat, halve it.
• The rate is a national average. US residential rates vary by more than a factor of two between states. Take the kWh figures and multiply by the rate on your own bill.

The arithmetic behind every dollar figure in the table is set out step by step on what an electric blanket costs to run, and broken down by duration on cost per night and cost per month.
