The 10% rule, and its wiggle room
The Sleep Foundation describes a blanket weighing about 10% of your body weight as the usual rule of thumb, but notes preferred weights range from 5% to 12% and that people may need to try more than one weight. Its chart turns that into ranges:
| Your body weight | Blanket weight range |
|---|---|
| 50 to 120 lbs | 5 to 12 lbs |
| 75 to 180 lbs | 7 to 18 lbs |
| 100 to 240 lbs | 10 to 24 lbs |
| 125 to 300 lbs | 12 to 30 lbs |
| 150 to 360 lbs | 15 to 36 lbs |
The Sleep Foundation stresses these figures reflect preferences, not an exact science.
10 lb, 15 lb or 20 lb: who each suits
| Weight | Often suits | Trade-off |
|---|---|---|
| 10 lb | Smaller adults; people new to weighted blankets; a throw for the sofa. In the Sleep Foundation chart, 10 lbs is the low end for people around 100 lbs | Heavier people may barely notice it |
| 15 lb | Many adults around 150 lbs; side sleepers; people with sore joints. Baloo suggests its 15 lb Full/Queen for people over 65, side sleepers, and anyone with joint, knee, hip or back pain | May feel light to someone over 200 lbs |
| 20 lb | Adults nearer 200 lbs who like firm pressure. Baloo says healthy adults who sleep on their back or stomach may prefer 20 lb | Harder to wash and move; can feel too warm or confining |
Sleep position and body changes the answer
- Side sleepers have more weight landing on the hip and shoulder, and a maker like Baloo points them to its lighter Full/Queen option.
- Back and stomach sleepers spread weight more evenly and may tolerate more.
- Joint pain is a reason to go lighter, per the same maker guidance.
- Hot sleepers may want less weight or a breathable build; see our cooling weighted blanket guide.
- Bigger blankets spread weight. A queen or king size of the same weight presses down less on you than a single-person blanket. Our heaviest weighted blanket page explains the math.
Easing in
A new weighted blanket can feel heavy at first. Baloo's care page calls that normal and suggests using it on your lower body for the first few nights, trying short periods on the sofa, then moving it up to your chest, allowing one to two weeks to adjust. If you still feel trapped, sore or hot after that, go down a size rather than pushing through.
Children and other people who need a lighter touch
Never use a weighted blanket for a baby. The NIH Safe to Sleep campaign lists weighted blankets, weighted swaddles and other weighted objects among hazards in an infant's sleep area. For older children, the Sleep Foundation says weighted blankets are generally considered safe for ages 3 and up who weigh at least 50 lbs, advises against using the 10% rule for kids, and suggests talking to a family doctor and leaning toward the low end.
Adults with low blood pressure, a breathing disorder, type 2 diabetes or obstructive sleep apnea should talk to a doctor first, according to the Sleep Foundation, which also warns a blanket that is too heavy can restrict airflow.
