What Is a Weighted Blanket Calculator?
A weighted blanket calculator helps you choose a blanket that delivers comfortable deep-touch pressure without feeling oppressive. The most widely used guideline is roughly 10% of your body weight, often with one extra pound added for the blanket's structure. This tool applies that rule and also shows the broader 8–12% comfort range many manufacturers recommend.
How to Use It
Enter your body weight in pounds and the calculator returns the recommended blanket weight along with the acceptable lighter and heavier bounds. Use the central figure as your target, then pick the nearest commercially available size (blankets usually come in 5-pound increments such as 10, 15, 20, and 25 lbs).
The Formula Explained
The core equation is $$\text{blanket\_weight} = \text{body\_weight} \times 0.10 + 1$$ The 10% factor sets the bulk of the pressure relative to your size, while the +1 lb compensates for filling distribution and fabric. The range bounds use 8% (lighter, cooler) and 12% (heavier, more grounding) of body weight.
Worked Example
For a 150 lb adult: $$150 \times 0.10 + 1 = 15 + 1 = \mathbf{16 \text{ lbs}}$$ The acceptable range is \(150 \times 0.08 = 12\) lbs up to \(150 \times 0.12 = 18\) lbs, so a standard 15 lb blanket fits comfortably.
FAQ
Is this safe for children? Weighted blankets are generally not recommended for toddlers or infants. Always consult a pediatrician and never use one that restricts movement or breathing.
What if my ideal weight falls between sizes? Round to the nearest available size within the 8–12% range; rounding down feels lighter and cooler.
Should I size for two people? No. Pick a blanket based on a single person's weight, not the combined weight, so each user gets appropriate pressure.
