What Weight of Weighted Blanket Should You Get?

Most makers suggest a weighted blanket that weighs about 10 percent of your body weight, so a 150-pound adult would look at 15 pounds. The Sleep Foundation says people’s preferences range from 5 to 12 percent. If you fall between two sizes, rounding down is the usual advice. Weighted blankets are never safe for babies.

How heavy should a weighted blanket be for your body weight?

Start with 10 percent, then adjust for comfort. This chart applies that rule to the weights most makers sell.

Bearaby, a weighted blanket maker, puts its own rule as 10 percent of body weight “plus one or two pounds.” It suggests first-time users round down between sizes, while people who already like heavy pressure may round up.

Does the 10 percent rule come from research?

Only loosely. It is a manufacturer and industry guideline, not a medical dose. The best-known clinical trial did not size blankets by body weight at all.

That 2020 trial, published in the Journal of Clinical Sleep Medicine and run at the Karolinska Institutet in Sweden, gave 120 adults with insomnia and a psychiatric condition either a weighted chain blanket or a light control blanket. The weighted group tried an 8 kg (17.6 lb) blanket. Ten participants found it too heavy and used a 6 kg (13.2 lb) version instead. The control blanket weighed 1.5 kg (3.3 lb).

What did the research find?

According to the American Academy of Sleep Medicine’s summary, nearly 60 percent of the weighted blanket group had their insomnia severity cut by half or more after four weeks, compared with 5.4 percent of the control group.

Keep the limits in mind. Every participant had both insomnia and a psychiatric diagnosis, such as depression, bipolar disorder, ADHD or generalized anxiety. The results may not apply to people without those conditions. One participant stopped because the blanket made them anxious.

We do not make health claims for weighted blankets. If you are buying one to help with sleep or anxiety, it is worth discussing with your doctor.

Who should not use a weighted blanket?

Babies and toddlers. A 2024 statement from CPSC Commissioner Richard Trumka cites CDC guidance that weighted blankets, swaddles and sleep sacks are not safe for infants, and the American Academy of Pediatrics warns they can lower infants’ oxygen levels. Bearaby does not recommend weighted blankets for toddlers or children under 4.

Anyone who cannot easily remove it. You should be able to push the blanket off without help.

People with certain health conditions. The Sleep Foundation suggests checking with a doctor first if you have low blood pressure, a respiratory disorder, type 2 diabetes or obstructive sleep apnea. People who feel claustrophobic may also dislike the pressure.

Small pets. Bearaby warns owners not to let a small dog or cat burrow under a weighted blanket alone, since it could be too heavy for them.

Size, fill and fabric

Weight is the main choice, but three other details shape how a blanket feels.

Size. Bearaby says the edges should fit you, not your mattress. Its knitted cotton blankets grow with weight: 40 by 64 inches at 10 pounds, up to 48 by 72 inches at 25 pounds.

Fill. Check what supplies the weight. Some blankets use a fill such as beads or pellets; our guide to glass bead weighted blankets compares the two. Bearaby says its knitted range is weighted entirely by hand-knit organic cotton, with no beads or pellets.

Warmth. A dense blanket can hold heat. If you sleep hot, look at knitted or cooling-labeled options, and pair it with lighter bedding. Our guide to cooling weighted blankets explains which fabrics and fills hold less heat, and our blankets section compares every type. Our sherpa vs fleece vs faux fur comparison explains why deep-pile covers feel warmer.

Care. Check the label before you buy. Bearaby says to wash its knitted blanket cold on a gentle cycle and tumble dry low, noting that it may need more than one drying cycle.

Is a weighted blanket a good gift?

A weighted blanket can be a good gift, but it is a sized gift, closer to shoes than to a throw. The right weight depends on the person’s body weight: makers suggest about 10 percent, and Bearaby adds “plus one or two pounds.” A blanket that is too heavy for them is uncomfortable, and one that is too light may not give the pressure they want.

So before you buy:

• Ask, or ask someone close to them. A rough body weight is enough to pick between the common 10, 15 and 20 pound sizes.
• If you cannot ask, include a gift receipt and choose a seller with a clear return policy. Weighted blankets are heavy and costly to ship back, so check the policy before you order.
• Think about warmth. For someone who sleeps hot, a knitted or cooling-labeled blanket is a safer guess than a dense one.
• Never buy one for a baby or toddler. Weighted blankets are not safe for infant sleep, and Bearaby does not recommend them for children under 4.

If the weight is a guess, a regular throw, a silk pillowcase or slippers make safer presents. Our cozy gifts guide sorts ideas by moment and interest, and our guide to gifts for nurses and night-shift workers covers sleep gifts for people who sleep during the day.
