Weighted Blanket Calculator

Estimate a comfortable weighted blanket weight for your body using the widely used “about 10% of body weight” guideline — with clear age and safety cautions.

Estimate your weighted blanket weight

How this calculator works

Many weighted-blanket makers and general sleep resources suggest choosing a blanket that weighs roughly 10% of your body weight, commonly within an 8–12% range. This calculator simply applies that guideline to the weight you enter and shows a sensible range so you can pick what feels calming and easy to move under.

This is a general comfort guideline, not a medical formula. Personal preference matters more than a precise number — some people prefer a little lighter or heavier. If a blanket ever feels too heavy to move under comfortably, choose a lighter one.

Safety & age cautions

  • Not recommended for infants and toddlers. A weighted blanket a child cannot easily remove can be unsafe.
  • For young children, use only with adult guidance and consider talking to a pediatrician first.
  • Check with a qualified healthcare professional if you have a respiratory condition, sleep apnea, circulatory issue, low blood pressure, or claustrophobia.
  • Qumfy is an educational wellness tool. This calculator does not diagnose or treat any condition and is not a substitute for professional medical advice.

How heavy should a weighted blanket be?

Are weighted blankets safe for children?

What size weighted blanket should I buy?

Choose a blanket sized to your body, not your mattress — it should cover you rather than drape over the bed edges (which pulls it off you). For a shared bed, many people prefer separate individual blankets.
