Choosing the right weighted blanket weight in kilograms helps you feel calm without feeling pinned down. The usual rule of thumb is to select a blanket that is around eight to twelve percent of your body weight, but there are exceptions and preferences to consider. This guide explains simple sizing in kg, how to adjust for heat and sleep position, and how to choose sizes for adults and children safely in UK homes.
Deep pressure comfort comes from weighted blankets with breathable covers.
The Simple Weight Rule
Start with eight to twelve percent of body weight. If you weigh 60 kilograms, a five to seven kilogram blanket is a good starting point. At 75 kilograms, consider a six to nine kilogram blanket. If you sleep hot, start at the lower end of the range. If you want a more grounded feeling and you do not overheat, you may prefer the higher end. Many brands offer 5 kg, 7 kg and 9 kg options for adults. If you are between weights, choose the lighter blanket first. It is easier to add a breathable cover or pair with a warmer duvet than to fight a blanket that feels too heavy.
Adults vs Children
Adults can generally choose within the eight to twelve percent range based on preference. Children require more care. Weighted blankets are not suitable for very young children or for anyone who cannot remove the blanket on their own. For older children, aim for eight to ten percent of body weight and choose a smaller size that covers the body without draping far over the edges of the bed. A three kilogram blanket is a common children’s option. Always consult a clinician if the blanket is being considered for a specific therapeutic purpose.
Cooling and Fabric Choices
If you tend to overheat, pick a blanket with a breathable cover such as bamboo or lyocell and glass bead fill rather than plastic pellets. These covers have a cool touch and wick moisture, which makes summer use more comfortable. In winter or if you like a snug feel, a minky or fleece cover provides extra warmth. Duvet style covers that you can swap seasonally make care easier and allow you to adjust how warm the blanket feels without changing the weight.
Size and Coverage
Choose a personal size that covers your body rather than a full bed size that hangs over the sides. Overhang can make the blanket creep toward the floor and feel heavier than intended. Personal throws are easier to move under and tend to sleep cooler. If you want to share, a larger throw can work on a sofa, but for bed use two personal blankets often keep both partners more comfortable, especially if your weight or temperature preferences differ.
Sleep Position and Movement
Side sleepers often prefer the lower end of the weight range because the blanket presses on a smaller contact area on the shoulder and hip. Back sleepers may feel comfortable with a slightly heavier option. If you move frequently, a lighter blanket is easier to turn under without waking. If you tend to settle in one position, a heavier blanket may feel more soothing.
Safety and Use
Do not use a weighted blanket on anyone who cannot move it unaided. Avoid covering the head or neck. Use lower weights for frail individuals and consult a clinician for guidance if there are circulation, respiratory or temperature regulation concerns. For pets, choose a lighter throw rather than a heavy blanket, as animals can overheat or become trapped.
Care and Maintenance
Many weighted blankets use a removable cover that is machine washable, while the inner weighted layer requires spot cleaning or a gentle cycle in a large drum. Always check the label. Air dry whenever possible. Use the inner ties to secure the cover so weight remains evenly distributed. If beads pool in one area, shake the blanket to redistribute before sleep.
Simple weight ranges and breathable fabrics appear in weighted blankets for UK sleepers; comfortable layering adds breathable sheets and a suitable duvet.
FAQs
Is a 9 kg weighted blanket too heavy? It depends on your body weight and preference. For a 75 to 90 kilogram adult who sleeps on the back and does not overheat, it can be comfortable. If you are lighter or sleep hot, start at 5 to 7 kg.
Can two people share one weighted blanket? You can, but personal sized blankets often feel better and run cooler because each person can move independently and choose a suitable weight.
Are weighted blankets safe for children? Only for older children who can move the blanket themselves. Use lighter weights around eight to ten percent of the child’s weight and seek clinical advice if needed.
