Weighted Blanket Calculator
Estimate the best weighted blanket weight for one sleeper or a couple, compare a comfortable range, and find the nearest common blanket size.
Find a comfortable weighted blanket size
A weighted blanket calculator estimates blanket weight from body weight and how the blanket will be used. For one person, a common starting point is about 10% of body weight, and this calculator also shows a lighter-to-firmer comfort range.
For couples, the calculator uses 7.5% of combined body weight and warns when a shared blanket may not feel balanced. The result is a planning estimate, not medical advice.

Safety note: A weighted blanket should never trap the sleeper or feel difficult to remove. Avoid weighted blankets for infants, toddlers, or anyone with breathing, circulation, mobility, or heat-sensitivity concerns unless a healthcare professional says it is appropriate.
How to use the weighted blanket calculator
- Choose the blanket use: Select one person or a couple sharing one blanket.
- Select the unit: Enter body weight in pounds or kilograms.
- Add sleeper details: Choose the sleeper type and preferred pressure level.
- Enter body weight: For couples, enter both weights so the calculator can check the combined recommendation.
- Review the result: Compare the recommended blanket weight, comfort range, nearest common size, and safety note.
Weighted blanket formulas
Weighted blanket sizing is usually based on body weight. A common single-person starting point is about 10% of body weight, while a shared couple blanket is often lighter per person because the pressure is spread across two sleepers.
Calculate weighted blanket weight by using 8% to 12% of body weight. A person weighing 150 pounds typically uses a blanket weighing 12 to 18 pounds. Children should use weighted blankets only when recommended by a healthcare professional. Comfort preferences and sleep habits can affect the final blanket weight.
Single blanket = body weight x 10% + 1.5 lb
Metric equivalent: body weight x 10% + 0.68 kg
Couple blanket = combined body weight x 7.5%

Worked examples
Use these examples as quick checks. The nearest size depends on the weights available from the brand you buy.
| Scenario | Formula | Recommended weight |
|---|---|---|
| 150 lb adult | 150 x 10% + 1.5 lb | 16.5 lb, nearest 17 lb |
| 70 kg adult | 70 x 10% + 0.68 kg | 7.68 kg, nearest 8 kg |
| 160 lb + 140 lb couple | (160 + 140) x 7.5% | 22.5 lb shared blanket |
Choosing between two blanket weights
Weighted blankets are usually sold in fixed sizes, so your exact result may fall between two products. The better choice depends on sleeper strength, heat sensitivity, fabric, fill type, and whether the blanket will be used all night or only while relaxing.
Choose lighter if unsure
A lighter blanket is usually easier to remove, cooler, and better for first-time users.
Check the blanket size
A large blanket spreads the same weight over more area, so it can feel less intense than a smaller throw.
Consider fabric and fill
Glass bead, pellet, knit, cotton, bamboo, and fleece blankets can feel different even at the same weight.

Weighted blanket weight chart
If you want a quick estimate before using the calculator, start near 10% of body weight for one adult, then compare nearby retail sizes. The chart below shows common starting points, not a medical rule.
| Body weight | 10% estimate | Common blanket size to compare | Helpful note |
|---|---|---|---|
| 100 lb | 10 lb | 10 lb or 12 lb | Choose lighter if the sleeper is smaller, younger, or heat-sensitive. |
| 125 lb | 12.5 lb | 12 lb or 15 lb | A 12 lb blanket usually feels easier for first-time use. |
| 150 lb | 15 lb | 15 lb or 17 lb | This is a common adult range for balanced pressure. |
| 175 lb | 17.5 lb | 17 lb or 20 lb | Pick based on whether you prefer lighter or firmer pressure. |
| 200 lb | 20 lb | 20 lb or 25 lb | A larger blanket can make the same weight feel less intense. |
| 250 lb | 25 lb | 25 lb or 30 lb | Make sure the blanket is still easy to move and remove. |
Tip: if your exact result falls between two products, compare the smaller and larger options against the comfort range shown by the calculator.
Blanket size and coverage guide
Weight is only one part of the fit. The same 15 lb blanket can feel different as a small throw, a twin-size blanket, or a queen-size blanket because the pressure is distributed across a different surface area.
For one sleeper
Choose a size that covers the body from shoulders to feet without hanging far over the mattress. Less overhang keeps more of the listed weight on the sleeper instead of pulling over the bed edges.
For couples
A shared blanket works best when both sleepers like similar pressure and temperature. If one person wants a much heavier or cooler feel, two individual blankets are usually easier to dial in.
For couches and naps
A throw-size weighted blanket can feel more concentrated than a bed-size blanket at the same listed weight. This is useful for short relaxation sessions but may feel too intense for all-night sleep.
For hot sleepers
Look for breathable covers, smaller sizes, removable duvet covers, or open-knit designs. Avoid choosing extra weight just because the blanket is marketed as cooling.
Fit, comfort, and safety checklist
Before buying or keeping a weighted blanket, use this checklist to turn the calculator result into a practical decision. The best blanket should feel calming without limiting movement, overheating the sleeper, or becoming hard to remove.
Before you buy
- Compare the calculator result with the brand's actual available weights.
- Check the return policy in case the pressure feels too strong after a few nights.
- Confirm care instructions, especially if the blanket is too heavy for your washer.
When you try it
- Use it for a short rest first before sleeping under it all night.
- Make sure the sleeper can roll, sit up, and remove the blanket without help.
- Stop using it if it causes discomfort, overheating, breathing difficulty, or anxiety.
Interesting Fact
Sleep comfort is a major reason people compare weighted blanket options, and the need is not small. The CDC reports that in 2022, the percentage of adults who did not get enough sleep ranged from 30% in Vermont to 46% in Hawaii. A weighted blanket is not a treatment for sleep disorders, but choosing a safe, comfortable weight can be one part of a better sleep environment. Source: CDC FastStats: Sleep in Adults.
Frequently Asked Questions
How much should a weighted blanket weigh for an adult?
For most adults, a common starting point is about 8% to 12% of body weight, with 10% used as a simple middle estimate. This weighted blanket calculator gives the recommendation in pounds or kilograms and also shows a comfort range, so you can choose lighter or firmer pressure if the exact weight is not sold.
How do I calculate weighted blanket weight for couples?
For a shared blanket, this calculator uses 7.5% of the couple's combined body weight because the pressure is spread across a wider bed-size area. If the two sleepers have very different weights, sleep temperatures, or comfort preferences, separate blankets often feel better than one large shared size.
Should a weighted blanket cover the whole bed?
Not always. Many weighted blankets are designed to cover the sleeper rather than hang over the sides of the bed. Extra-wide fabric spreads the same filling over more surface area, so the listed blanket weight may feel lighter on the body than a smaller throw with the same number of pounds.
Are weighted blankets safe for a child, toddler, or sensory needs?
Use extra caution for any child, and do not use weighted blankets for infants or toddlers. For children with sensory needs, autism, ADHD, breathing concerns, mobility limits, or medical conditions, use a weighted blanket only when recommended by a healthcare professional and only if the child can remove it without help.
What if I am between two weighted blanket sizes?
If you are new to weighted blankets, sleep hot, or have any safety concern, choose the lighter size first. If you already like deep pressure and can comfortably lift and remove the blanket, the heavier recommendation may feel better for rest and relaxation.
Can a weighted blanket help with anxiety, stress, or insomnia?
Some people use a weighted blanket because steady pressure feels calming during rest, relaxation, or a bedtime routine. It is not a treatment for anxiety, stress, or insomnia, so speak with a healthcare professional if sleep problems are ongoing or severe.
Do weighted blankets make you hot while you sleep?
They can, especially if the blanket uses thick fabric, dense filling, or a warm duvet cover. If you sleep hot, consider breathable cotton, bamboo-style covers, glass beads, a lighter weight, or a smaller size that does not trap extra fabric around you.
Is a heavier weighted blanket always better?
No. A blanket that is too heavy can feel restrictive, make changing positions harder, and reduce comfort instead of improving it. The best option is heavy enough to feel calming but light enough that you can remove it easily, which is why the calculator shows a range instead of only one fixed weight.
