## Inputs

- **Body Weight** (lbs) — min 30, max 500 — Your body weight in pounds.
- **Height** (inches) — min 36, max 84 — Your height (composite ft+in entry on imperial; cm on metric).

## Details

The standard guideline is to choose a weighted blanket that is approximately 10% of your body weight. This provides enough pressure for the calming deep-touch effect without feeling too heavy or restrictive.

  - Weight: 10% of body weight, rounded to the nearest common size (5, 7, 10, 12, 15, 17, 20, or 25 lbs)

  - Size: The blanket should cover your body from chin to feet but should not hang over the sides of the bed, as the overhang weight pulls the blanket off you

  - Sleep position: Stomach sleepers may find the standard weight too heavy and should go 1-2 lbs lighter

Weighted blankets are filled with micro glass beads or plastic pellets sewn into small pockets to distribute weight evenly. Studies have shown they can reduce anxiety, improve sleep onset time, and increase overall sleep quality. They are especially popular for people with insomnia, anxiety, ADHD, and sensory processing differences.

When shopping, look for blankets with small quilted pockets (4-6 inch squares) for the most even weight distribution, and choose breathable materials like cotton or bamboo if you tend to sleep hot.

## Frequently Asked Questions

**Q: Why 10% of body weight?**

A: The 10% rule comes from occupational therapy research on deep pressure stimulation. This amount of weight provides a gentle, even pressure that mimics the sensation of being held, which triggers the release of serotonin and melatonin while reducing cortisol levels.

**Q: Can a weighted blanket be too heavy?**

A: Yes. A blanket that is too heavy can feel restrictive, cause overheating, or make it difficult to move during sleep. If 10% feels too heavy, go down to 7-8% of your body weight. Never use a weighted blanket that you cannot easily remove yourself.

**Q: Are weighted blankets safe for children?**

A: Weighted blankets are generally safe for children over 3 years old who weigh at least 50 pounds. Always use the 10% rule and ensure the child can remove the blanket independently. They should never be used for infants or toddlers.

**Q: Should I size the blanket to my body or my bed?**

A: Size it to your body, not your bed. A weighted blanket should cover you from shoulders to feet but should not hang over the bed edges. Overhang causes the weight to pull the blanket off, reducing effectiveness.
