Choosing the right weight for your child's weighted blanket is a crucial decision that affects both safety and effectiveness. A blanket that's too light won't deliver the expected benefits, while one that's too heavy can be uncomfortable or even dangerous. This guide explains how to find the ideal weight for your child.
The 10% Body Weight Rule
The simplest and most widely used method is selecting a blanket weighing approximately 10% of your child's body weight. This rule works in most cases and is recommended by occupational therapists and pediatricians.
For example, if your child weighs 30 kg, the appropriate blanket should weigh around 3 kg. If your child's weight falls between available sizes, always choose the lighter option. Your child should be able to move freely and remove the blanket independently at any time.
Choosing Weight by Age and Body Mass
Here's a practical guide to help you select the right weighted blanket for your child:
2 kg blanket (100×150 cm) works well for children weighing 15-25 kg. These are typically toddlers aged 3-6 years. This size is ideal for starting the weighted blanket journey.
3 kg blanket (120×180 cm) suits children weighing 25-35 kg, ages 6-10. The larger size ensures full body coverage for growing children.
4 kg blanket (120×180 cm) is designed for children weighing 35-45 kg, ages 10-14. Same dimensions as the 3 kg blanket but with more weight for older children.
5 kg blanket (150×200 cm) is the option for teens weighing 45-55 kg. The largest size, which can also serve adults with lower body weight.
When to Choose a Lighter Blanket
In some situations, it's worth choosing a lighter blanket than the 10% rule suggests:
If your child has never used a weighted blanket before, start with a lighter version. This allows gradual adjustment to the additional pressure. Some children immediately love the feeling of weight, others need time to adapt.
Children with breathing problems, cardiovascular conditions, or other health issues should use lighter blankets — always after consulting a doctor.
During warmer months, a lighter blanket provides comfort without overheating. Our blankets use breathable materials, but weight generates additional warmth.
When to Consider a Heavier Blanket
Some children prefer stronger pressure. If after a few weeks your child says the blanket is "too light" or you don't notice sleep improvement, you might consider the next weight size.
Children with ADHD, autism, or sensory processing disorders often respond better to more noticeable pressure. However, every child is different — observe reactions and adjust your choice.
Safety First
Regardless of the chosen weight, remember these basic safety rules:
Weighted blankets are suitable for children aged 3 and older. Younger children should not use weighted blankets due to suffocation risk.
Your child must be able to remove the blanket independently. If they struggle with this, the blanket is too heavy.
The blanket should cover only the body, never the head or face. Make sure your child understands this rule.
Consult your pediatrician if your child has any health concerns before introducing a weighted blanket to their sleep routine.
Summary
Choosing the right weighted blanket weight for your child doesn't have to be complicated. Start with the 10% body weight rule, choose the lighter option when in doubt, and observe your child's reactions. A properly chosen blanket will help your little one fall asleep faster, sleep more peacefully, and wake up refreshed.
