How Heavy Should a Weighted Blanket Be? Weight Chart and Buying Tips

Updated October 21, 2026 · The Bedroom Edit buying guide

Short answer: start with a weighted blanket that weighs about 10% of your body weight, then round to the nearest size sold. If you weigh 150 lbs, that means a 15 lb blanket. People’s preferences run from about 5% to 12% of body weight, so go lighter if you run warm, feel closed in easily or are new to weighted blankets. Children need more care: the usual guidance is age 3 or older and at least 50 lbs, and a check with their doctor first.

The 10% rule, and why it’s only a starting point

A weighted blanket is meant to give steady, gentle pressure. Too light and you barely notice it. Too heavy and it can feel trapping or hard to move under. The common rule of thumb is about 10% of your body weight, but that’s a starting point, not a prescription. Sleep Foundation describes a preferred range of roughly 5% to 12% of body weight and says it may take trying a couple of weights to find yours.

Most weighted blankets weigh between 5 and 30 lbs, which is far heavier than a normal comforter. The weight usually comes from plastic pellets or glass microbeads sewn into small pockets so it stays spread out.

Percentages from Sleep Foundation’s “How Heavy Should a Weighted Blanket Be?” page, read October 21, 2026. The pound figures are simple arithmetic on those percentages, rounded. Sleep Foundation notes these are based on user preference, not an exact science.

• Between two sizes? Most people starting out round down. You can always add a comforter on top; you can’t make a heavy blanket lighter.
• Weight isn’t the only feel: fill, cover fabric and how evenly the weight is stitched in all change how heavy a blanket feels and how warm it sleeps.

Size: cover your body, not the bed

Weighted blankets are usually meant to lie on top of you, not hang over the sides of the mattress. A blanket that drapes over the edges tends to slide off as the weight pulls it down. Many are sized close to the sleeper’s body rather than the full bed. If you share a bed, check whether the blanket is meant for one person or two; two single-person blankets let each sleeper pick their own weight.

Running warm? Look at the fabric and fill

• Cover fabric: breathable weaves such as cotton tend to sleep cooler than plush or minky fabrics.
• Fill: glass microbeads are smaller and denser than plastic pellets, so the same weight can come in a thinner blanket.
• Batting: extra padding reduces the feel and sound of the beads shifting, but adds warmth.
• Removable cover: makes washing far easier, since many full-weight blankets are too heavy for a home washer.

Who should check with a doctor first

Weighted blankets aren’t for everyone. A blanket that’s too heavy can press on the chest and make breathing harder, so talk to a doctor before using one if you have a breathing or respiratory condition, obstructive sleep apnea, low blood pressure or type 2 diabetes. Sleep Foundation lists these conditions. Some people also find any weighted blanket too confining.

For children, weighted blankets are generally considered only for kids age 3 and older who weigh at least 50 lbs. Be cautious with the 10% rule for a child, ask their doctor about the right weight, and lean toward the lighter end. Never use a weighted blanket for a baby or toddler.
