Adult comfort reference
Weighted Blanket Weight Calculator
Calculate a ten-percent adult body-weight reference, then check the product's size, instructions and whether you can remove it independently.
The number is arithmetic, not a safety clearance or a prescription. This calculator is for adults; do not use it to size a blanket for a child or baby.
Research and practical examples
What weight weighted blanket should I get?
The result is your entered adult body weight multiplied by 0.10. For example, 150 lb produces a 15 lb reference; 153 lb produces 15.3 lb. We retain the arithmetic instead of rounding up to a purchasable blanket. If shops offer 15 lb and 20 lb, this calculation does not establish that the heavier option is appropriate.
What the ten-percent figure leaves out
RCOT’s occupational-therapy guidance says to follow the maker’s size and weight instructions, which usually specify no more than ten percent of body weight. It also considers removal ability, breathing, temperature regulation and individual circumstances. The number alone cannot assess those factors. If suitability is uncertain, seek individual professional advice before use.

Two adults need two separate checks
For 150 lb and 180 lb, the displayed references are 15 lb and 18 lb separately. Adding them to recommend a 33 lb shared blanket would ignore how the blanket lies on each person. Width, length, drape and the exact design change the comparison; our tool does not calculate a shared-blanket prescription.

Choose dimensions and care with the weight
Read the selected maker’s coverage and use instructions. A throw, personal blanket and bed-size blanket can distribute the same listed weight differently. Check whether the cover and weighted insert have separate care labels and whether the washing machine can handle the permitted load. A fabric name alone does not establish overnight cooling. Our temperature field records your preference; it does not change the weight calculation or measure a fabric’s performance.
Record whether you find the item comfortable and easy to remove. The result does not predict an anxiety or sleep improvement. For another bedding decision, use our pillow height calculator.

How the weight is calculated
The formula is entered body weight multiplied by 0.10, displayed to one decimal where needed. Temperature preference does not alter the calculation. The result is not a retail weight selection, a shared-blanket weight or a safety assessment.
Warmth and care are product-specific
The calculator records whether you tend to feel hot or cold. It does not test cooling or assign a proven performance benefit to bamboo-derived fabric, cotton or minky. Check the complete blanket, its dimensions and the separate cover/insert care labels.
What weight weighted blanket should I get?
Ten percent of adult body weight is a common arithmetic reference, not proof that a product is suitable. For example, 150 lb gives 15 lb. Follow the maker's instructions and consider your ability to remove it independently; seek individual advice when suitability is uncertain.
Should I round 15.3 lb up to a 20 lb blanket?
This calculator does not recommend that. It displays the arithmetic reference without rounding up to a purchasable weight. Compare the exact manufacturer's instructions and individual suitability before selecting any product.
Can two adults add their calculated weights together?
No shared recommendation is calculated. Two-adult mode displays one reference for each adult. Their sum does not account for the blanket's dimensions or the weight distributed over either person.
Can I use this calculator for a baby or child?
No. This is an adult reference tool. NIH Safe to Sleep advises against weighted blankets for babies; an adult percentage calculation is not a children's sizing or safety assessment.
Does a heavier blanket guarantee better sleep?
No. This calculator predicts no treatment, anxiety or sleep outcome. More weight is not automatically more suitable. The number alone cannot assess removal ability, breathing or temperature regulation.
