Weighted Blanket
Weight Calculator
Determine the ideal weight and size for your weighted blanket based on your body dimensions and bed size for optimal sensory sleep therapy.

The Science of Deep Pressure Stimulation (DPS)
Weighted blankets work through a clinical therapeutic mechanism known as Deep Pressure Stimulation (DPS) or Deep Touch Pressure. By applying gentle, distributed pressure across the body, it mimics the sensory experience of a firm hug, holding, or swaddling.
Autonomic Nervous System Shift
Weighted pressure shifts your autonomic nervous system from a state of arousal (the sympathetic "fight-or-flight" system) into a resting state (the parasympathetic "rest-and-digest" system). This down-regulation leads to:
- Reduced Heart Rate: Sensory input relaxes heart rate variability.
- Cortisol Reduction: Lowers circulating stress hormone levels.
- Serotonin & Melatonin Boost: Pressure triggers chemical pathways that release neurotransmitters needed for sleep preparation.
How to Choose the Right Dimensions
A common mistake is buying a weighted blanket that matches your bed size exactly (like a standard King comforter). A heavy blanket that hangs over the edge of the mattress will naturally pull itself to the floor due to gravity. Instead:
- Twin Beds: Use a standard 48" x 72" blanket.
- Queen Beds: Use a 60" x 80" blanket (focuses weight on the sleeping area).
- Children: Use smaller dimensions (such as 36" x 48") so that the weight remains concentrated on their smaller bodies.
⚠️ Crucial Pediatric Safety Rules
While highly effective for calming sensory overstimulation and ADHD, weighted blankets carry strict medical rules for young children:
- No Toddlers/Infants: Never use a weighted blanket for children under 2 years of age or anyone under 30 pounds. Doing so presents a high risk of accidental suffocation.
- Independent Removal: A child must be strong enough to pull the blanket off their head and body independently. Never use a weighted blanket as a physical restraint.
- Breathing Safety: The blanket should never cover the head or face. Do not use if the user has asthma, sleep apnea, or other respiratory concerns without consulting a pediatrician.
