We get asked about weighted blankets almost as often as we get asked about pillows, and usually the first question is the same: "How heavy should mine be?" It's a fair question, because a weighted blanket that's the wrong weight can feel more like a chore than a comfort. Too light and you barely notice it's there. Too heavy and you spend the night shoving it off, which defeats the purpose entirely.

This guide walks through how we think about weight selection, from the basic body-weight math to the adjustments that actually matter, like sleeping position, fabric, and whether you're sharing a bed. None of this replaces advice from a doctor or occupational therapist, especially if you're choosing a weighted blanket for a child, for anxiety, or for a sensory processing condition. But if you're just trying to figure out what to order for yourself, this should get you most of the way there.

What weighted blankets are meant to do

Weighted blankets use evenly distributed weight, usually from glass beads or plastic pellets sewn into small pockets, to apply gentle, consistent pressure across the body. This is sometimes called deep pressure stimulation. The idea is that the pressure can help some people feel calmer or more settled at bedtime, similar to the effect of a firm hug or swaddle.

It's worth being honest about what the evidence actually supports. Some small studies and a lot of anecdotal reports suggest weighted blankets can help with settling into sleep or reducing restlessness, particularly for people with anxiety or sensory sensitivities. But they are not a daily routine, and they won't fix restful sleep support caused by an underlying health condition. If sleep problems are persistent, a conversation with a doctor is a better first step than a heavier blanket.

What we can say from years of fitting customers with the right blanket is this: the "right" weight is personal, and it depends on your body size, how you sleep, and what kind of pressure feels soothing versus restrictive. There's no universal number that works for everyone, which is exactly why the calculation below is a starting point, not a rule.

How to calculate a starting weight

The most common guideline, and the one most manufacturers build their size charts around, is that a weighted blanket should be about ten percent of your body weight. So if you weigh 150 pounds, you'd start by looking at a 15-pound blanket. If you weigh 200 pounds, that points to a 20-pound blanket.

Here's a simple reference table using that ten percent rule:

Most brands stop making blankets heavier than 25 or 30 pounds because beyond that, the blanket becomes difficult to move, wash, or fold, and the pressure can start to feel restrictive rather than calming for most adults. If you're on the higher end of the weight range and the math suggests something above 25 pounds, we'd usually recommend staying at 20 to 25 pounds and seeing how that feels first, rather than chasing the exact percentage.

For children, the calculation is different and needs more caution. Many pediatric occupational therapists suggest weights closer to five to ten percent of body weight, and weighted blankets are generally not recommended for children under two, or for anyone who can't remove the blanket on their own. If you're buying for a child, talk to their pediatrician or an occupational therapist before choosing a weight, rather than relying on a general formula.

Adjusting for sleeping position and preference

Body weight is the starting point, but how you sleep changes how a given weight actually feels. Someone who sleeps on their stomach, for instance, often finds the same blanket feels heavier than someone who sleeps on their back, simply because more of the blanket's weight rests directly on the chest and ribs rather than spreading across a wider surface.

A few practical adjustments we suggest:

• Back sleepers: The ten percent guideline usually works well as-is, since weight distributes fairly evenly across the torso and legs.
• Side sleepers: Consider sizing down slightly, maybe seven to eight percent of body weight, since the blanket's weight concentrates more on the shoulder and hip that are bearing contact with the mattress.
• Stomach sleepers: A lighter blanket, closer to six to eight percent of body weight, is often more comfortable, since chest pressure while lying face down can feel constricting at higher weights.
• People who move a lot at night: A lighter blanket in a smaller size (one that doesn't drape over the mattress edges) tends to work better, since a heavy blanket that shifts with you can end up half on the floor by morning.

Personal preference matters just as much as sleep position. Some people genuinely enjoy the sensation of being pinned down and will gravitate toward the higher end of any range we suggest. Others find even a moderate weight claustrophobic and do better starting lighter than the formula suggests, then sizing up later if they want more pressure. If you're unsure, it's almost always easier to start slightly lighter and adjust up than to buy heavy and feel stuck with something uncomfortable.

Fabric and fill choices that affect feel

The material covering a weighted blanket changes how the same weight feels on your skin, and it affects temperature just as much as pressure. This matters especially for people who run warm at night, since weighted blankets by their nature trap more heat than a standard duvet.

Common fill materials include:

• Glass beads: Small, dense, and quiet. They allow for a thinner blanket profile at a given weight and tend to feel less lumpy over time than plastic pellets.
• Plastic poly pellets: Less expensive, but bulkier for the same weight, and some people notice a faint rustling sound when the blanket moves.
• Steel shot beads: Even denser than glass, allowing for a very slim blanket, though these tend to appear on premium models only.

Cover fabric matters just as much. Cotton and cotton-blend covers breathe well and suit most bedrooms. Minky or plush covers feel soft against skin but retain more heat, which can be a problem in a warm room or for anyone who already sleeps hot. Bamboo or linen blends sit in between, offering a cooler hand-feel with a bit more texture than plain cotton.

If temperature is a concern, we usually point people toward a lighter-weight cotton or bamboo cover rather than assuming they need to compromise on the blanket's actual weight. A 15-pound cotton blanket and a 15-pound minky blanket apply the same pressure, but they will feel very different by 2 a.m. in a warm bedroom.

Shared beds and couples' considerations

Weighted blankets get complicated fast when two people share a bed, mainly because the ten percent rule is built for one body, not two. A blanket sized for a 300-pound combined household weight would be too heavy and bulky to be practical or safe for most people to lift and manage.

There are three common approaches couples take:

1. Two separate blankets: Each person gets a blanket sized to their own body weight, and you layer them side by side on the bed. This is the most personalized option and avoids the whole "my side is too heavy, your side is too light" problem, though it can look a bit patchwork.
2. One shared blanket sized to the lighter partner: This avoids overloading the smaller person but often leaves the heavier partner feeling like the pressure is too mild to notice.
3. One larger blanket weighted between both partners' averages: Some brands sell queen or king weighted blankets in the 20 to 25 pound range specifically for this. It's a compromise weight, not a perfect fit for either person, but it works reasonably well for couples who are close in body weight.

Whichever route you choose, remember that a shared weighted blanket is heavier and less flexible to adjust than a regular duvet, so if one partner wants to remove it and the other doesn't, that's worth discussing before buying rather than after.

Signs a blanket is too heavy or too light

It usually takes two or three nights to know if a weighted blanket is right for you, since the first night often comes with some novelty either way. After that initial adjustment, a few signs tend to point clearly in one direction or the other.

Signs it's too heavy: you find yourself pushing it off during the night without realizing it, you wake up with numbness or tingling in your arms or legs, or getting out of bed to use the bathroom feels like an effort because you have to fight the blanket off first. Persistent numbness or tingling is worth mentioning to a doctor if it continues, since it can indicate the pressure is restricting circulation rather than simply feeling heavy.

Signs it's too light: you barely notice it's there, you keep adding a second blanket on top for warmth or weight, or it doesn't feel meaningfully different from a regular duvet. In this case, sizing up five pounds or trying a denser fill material like glass beads instead of plastic pellets is usually the fix, rather than assuming weighted blankets "don't work" for you.

Common mistakes

A few patterns come up again and again with customers who end up disappointed:

• Buying the heaviest option available "to be sure it works." More weight isn't automatically more effective, and an uncomfortably heavy blanket often gets abandoned within a week.
• Ignoring the cover fabric and focusing only on the pound rating. A hot sleeper with a plush minky cover will blame the weight when the real problem is heat retention.
• Buying for a child using adult percentage guidelines. This can result in a blanket that's unsafe for a child to remove on their own.
• Assuming one blanket will suit two very different body weights. This almost always leaves one partner unhappy with the compromise.

Next steps

Start with the ten percent of body weight calculation as your baseline, then adjust down slightly if you sleep on your side or stomach, run warm at night, or tend to feel claustrophobic under heavy bedding. If you're buying for a shared bed, decide early whether you want two individual blankets or one compromise blanket, since that choice affects sizing more than anything else.

Give any new weighted blanket a fair trial of at least three or four nights before deciding it's wrong, since some adjustment is normal. But if you notice numbness, persistent discomfort, or you simply dread getting under it, don't force it, size down, switch cover fabric, or consult a doctor if something feels physically off. The right weighted blanket should feel like settling in, not like being pinned down.
