15 lb vs. 20 lb Weighted Blanket: Find Your Best Fit for Deeper Sleep

15 lb vs. 20 lb Weighted Blanket: Which Weight Should You Choose for Restful Sleep?

Weighted blankets are known for their calming, anxiety-reducing effects, but choosing the right weight is key to getting the best results. At Blanket & Bloom™, our hand-knit BloomKnit™ weighted blankets come in both 15 lb and 20 lb options. This guide will help you find the perfect match for your body, sleep preferences, and lifestyle.

Why Blanket Weight Matters?

The effectiveness of a weighted blanket relies on a principle called Deep Pressure Stimulation (DPS), which uses firm, even pressure to calm the nervous system. The right weight helps you fall asleep faster, stay asleep longer, and feel less anxious, while the wrong weight can feel overwhelming or ineffective.

How to Choose Between 15 lb and 20 lb?

Consider Your Body Weight

A common rule of thumb is to choose a blanket that’s about 8–10% of your body weight.

If you weigh 120 –160 lbs, a 15 lb blanket is usually ideal.

If you're 165 lbs or more, the 20 lb option may provide better pressure and comfort.

Think About Sleep Sensitivity

Light sleepers or those sensitive to pressure may benefit from the gentler feel of a 15 lb weighted blanket. If you tend to toss and turn, or need more grounding weight to stay still, a 20 lb blanket might work better.

Support for Anxiety & Stress

Both weights help reduce anxiety, but a 20 lb blanket may be more effective for those with higher stress levels due to its deeper cocoon-like pressure.
Studies like this one from Harvard Medical School show how weighted blankets support people with insomnia and anxiety.

Our BloomKnit™ Options: Breathable, Stylish, and Filler-Free

Whether you choose 15 lb or 20 lb, our BloomKnit™ weighted blankets are hand-knit from breathable, natural cotton perfect for hot sleepers and year-round comfort.
