How to choose a weighted blanket: weight, size and fill

The usual weight guideline, why a weighted blanket shouldn't be sized like a comforter, glass beads vs. plastic pellets, and who shouldn't use one.

Weighted blankets have a dedicated following, and many people say the gentle pressure helps them relax. Choosing one means getting the weight right, then the size, fill and cover.

Weight

The most common guideline from manufacturers is a blanket that weighs about 10% of your body weight, rounded to the nearest available size. Someone who weighs 150 lb would start around a 15 lb blanket.

That's a starting point, not a rule. If you've never used one, it can make sense to go slightly lighter. You should always be able to move the blanket off yourself easily.

Size: smaller than you think

Weighted blankets are meant to cover your body, not drape over the sides of the bed like a comforter. Extra fabric hanging over the edge pulls the blanket off you.

Single sizes (around twin width) suit one person.
Larger sizes for couples spread the weight over two people, so each person feels less of it.

Fill: glass beads vs. plastic pellets

Fill	Notes
Glass beads	Small and dense, so blankets are thinner and quieter for the same weight
Plastic pellets	Larger and bulkier; can be a bit noisier when you move
Other fills	Some blankets use organic or knitted designs without loose beads

Stitching in small pockets keeps the fill spread evenly, so it doesn't slide to one end.

Heat

Weighted blankets can feel warm. If you sleep hot, look for:

Breathable covers like cotton or bamboo-derived fabrics instead of minky or fleece.
Knitted designs, which let air through.
Removable covers, so you can switch between a warm winter cover and a cooler one.

Washing

Weighted blankets are heavy when wet. Check the care label:

Many have a removable, washable cover, while the inner weighted blanket is spot-cleaned or washed less often.
Heavier blankets may exceed what a home washing machine can handle.

Who shouldn't use one

Infants and toddlers. Safe sleep guidance from pediatric organizations advises against weighted blankets and other soft bedding for babies.
Anyone who can't easily remove the blanket on their own.
People with breathing problems, circulation issues or other health conditions should ask a doctor first.

Questions people ask

What if I'm between two weights?

Many people choose the lighter option at first, especially if they're new to weighted blankets.

Yes, with a larger size, but the weight is spread over two people. Some couples prefer two individual blankets.

Do weighted blankets help with sleep?

Many users report feeling calmer. Research results are mixed, so think of it as a comfort item rather than a treatment.
