About This Calculator
The Weighted Blanket Weight Calculator helps you find the perfect blanket weight for restful sleep and anxiety relief. Whether you are buying your first weighted blanket or choosing one for you and your partner, this tool uses clinically recommended formulas to calculate your ideal blanket weight based on body weight.
Weighted blankets work through deep touch pressure (DTP) therapy. The gentle, even pressure across your body stimulates the release of serotonin and dopamine — neurotransmitters that promote calmness and well-being — while reducing cortisol, the stress hormone. For maximum therapeutic benefit, the blanket needs to be heavy enough to provide adequate pressure but not so heavy that it becomes uncomfortable or unsafe.
How the Formula Works
For a single person, the recommended weighted blanket weight is calculated as: body weight ÷ 10 + 1.5 lbs (or 0.68 kg). This 10% rule plus a small fixed offset ensures the blanket provides effective deep touch pressure without being overly heavy. For example, a person weighing 150 lbs (68 kg) needs a blanket of approximately 16.5 lbs (7.5 kg).
For couples sharing one weighted blanket, the formula uses 7.5% of the combined body weight. This lower percentage accounts for the larger surface area, distributing the weight over two people. If there is a significant weight difference (more than 25%) between partners, separate blankets are recommended for each person.
Regional Notes
United States: Weighted blankets are typically sold in pounds with common sizes including 10, 12, 15, 20, and 25 lb options. The US market offers the widest variety of weighted blankets with different fill materials (glass beads, plastic pellets, steel shot).
United Kingdom: Weighted blankets are commonly measured in kilograms. Popular sizes include 4.5 kg, 6.8 kg, 9.1 kg, and 11.3 kg. UK retailers often provide both weight and size guidance for single and double beds.
India: The weighted blanket market is growing with options available on major e-commerce platforms. Most imported blankets are labelled in kilograms. Given the generally lower average body weight in India, blankets in the 4-7 kg range are most commonly recommended.
Always round to the nearest standard size available when purchasing. For example, if your ideal weight is 16.5 lbs, a 15 lb or 20 lb blanket would both be suitable choices. The exact weight matters less than being within a pound or two of the recommendation.
Frequently Asked Questions
How heavy should a weighted blanket be for me?
A weighted blanket should typically weigh about 10% of your body weight plus 1.5 pounds (0.68 kg). For a 150 lb (68 kg) person, the ideal blanket weight is approximately 16.5 lb (7.5 kg). This 10% rule of thumb is recommended by occupational therapists for deep touch pressure therapy.
What is the formula for calculating weighted blanket weight?
For a single person, the formula is: your body weight divided by 10, plus 1.5 pounds (or 0.68 kg in metric). In lbs: (body weight ÷ 10) + 1.5 lbs. In kg: (body weight ÷ 10) + 0.68 kg. For couples sharing one blanket, the recommended weight is 7.5% of your combined body weight.
Can I share a weighted blanket with my partner?
Yes, couples can share a weighted blanket if their weights are within about 25% of each other. For couples, calculate the blanket weight as 7.5% of your combined body weight. If the weight difference is greater than 25%, it is better to use separate weighted blankets tailored to each person's body weight for optimal comfort and therapeutic benefit.
Are weighted blankets safe for children?
Weighted blankets are not recommended for infants under one year old due to suffocation risk. For older children, weighted blankets can be used under adult supervision with approval from a healthcare professional. The blanket weight for children should follow the same 10% rule of body weight, typically on the lighter end of the recommendation.
What are the benefits of sleeping with a weighted blanket?
Weighted blankets provide deep touch pressure (DTP) stimulation which helps release serotonin and dopamine, neurotransmitters associated with calmness and well-being. Benefits include reduced stress and anxiety, improved sleep quality, decreased restlessness, and a sense of security similar to being hugged. Many users report falling asleep faster and experiencing fewer nighttime awakenings.
What is deep touch pressure (DTP) therapy?
Deep touch pressure (DTP) therapy is a therapeutic technique that applies gentle, firm pressure to the body to promote relaxation and reduce anxiety. Weighted blankets simulate DTP by evenly distributing weight across the body. This pressure stimulates the production of endorphins, serotonin, and dopamine while reducing cortisol levels, creating a calming effect on the nervous system.
How do I choose the right weighted blanket size?
Choose a weighted blanket size that matches your mattress size (twin, full, queen, king) but expect it to be slightly smaller than your mattress since weighted blankets are designed to cover the body, not the entire bed. For single sleepers, a twin or full-size blanket works well. For couples sharing one blanket, choose a queen or king size that comfortably covers both people.
Can I use a weighted blanket if I have a medical condition?
If you have a medical condition such as respiratory issues, circulatory problems, asthma, claustrophobia, or are recovering from surgery, consult your healthcare professional before using a weighted blanket. People with sleep apnea, low blood pressure, or those who are pregnant should seek medical advice. Weighted blankets are generally safe for healthy adults.
