How to Choose a Weighted Blanket: Weight, Fill and Fabric Explained
A weighted blanket only does its job at the right weight. Too light and it feels like an ordinary blanket with nothing added. Too heavy and it stops feeling calming and starts feeling restrictive, difficult to move under and unpleasant to sleep beneath. Getting the weight right matters more than any other decision in this category, more than fabric, more than fill type, more than brand.
Working out the right weight
The standard starting guideline is roughly ten percent of your body weight, with many people adding a small amount on top, commonly an extra kilogram or two, depending on personal preference for how much pressure feels comfortable rather than overwhelming. Someone weighing seventy kilograms would generally look at a blanket somewhere around seven to nine kilograms as a starting point, though preference genuinely varies and this is a starting range rather than a fixed rule.
Under 45kg body weight: around 3 to 5kg blanket. 45 to 65kg: around 5 to 7kg. 65 to 90kg: around 7 to 9kg. Over 90kg: around 9 to 11kg or more. Treat these as a sensible starting point and adjust from there based on what actually feels comfortable to you.
Fill types compared
Glass Beads
Most Common · Fine, Quiet, Even Distribution
Small glass micro-beads are the standard fill in most modern weighted blankets, valued for sitting quietly with minimal rustling and distributing evenly through the quilted pockets that keep the weight from shifting to one side. They add significant density in a small volume, which keeps the overall blanket from becoming bulky.
Plastic Pellets
Older Style · Bulkier, Sometimes Noisier
Plastic poly pellets were the original weighted blanket fill and remain in some budget options. They take up more volume than glass beads to achieve the same weight, making the blanket noticeably bulkier, and some users notice a faint rustling sound with movement that glass beads mostly avoid.
Fabric and temperature
Cotton is breathable and suits most bedrooms well across the year without running particularly warm. Minky and plush fabrics feel soft and cosy but trap heat more readily, which some people love in winter and find uncomfortable the rest of the year. Bamboo and other cooling-specific fabrics are built for hot sleepers or warmer climates, drawing heat away more effectively than cotton or minky, and are worth prioritising if you already run warm at night or live somewhere the room rarely cools down.
A note on how weighted blankets are thought to help
The general idea behind weighted blankets is deep pressure stimulation, gentle, even pressure across the body that many people describe as calming, similar to the feeling of a firm hug or a swaddle. Many users report feeling more settled and relaxed under one, particularly at bedtime, though individual response genuinely varies and a weighted blanket is a comfort tool rather than a treatment for any specific condition. If you have a diagnosed anxiety, sleep or sensory condition, it is worth discussing with a healthcare professional whether a weighted blanket is appropriate for your specific situation rather than relying on general product claims.
Care and washing
A fully filled weighted blanket is heavy, often too heavy or bulky for a standard home washing machine, and many manufacturers recommend spot cleaning or a laundrette's larger machines instead. A removable, washable duvet-style cover, sold separately from the weighted insert on many models, solves this in practice by letting you wash the cover regularly while spot cleaning the heavier inner layer far less often.
Weighted blankets are generally not recommended for young children, particularly under the guidance many manufacturers set around age three or a specific minimum weight, and never for infants. A child should never be under a weighted blanket heavier than roughly ten percent of their own body weight, and adult supervision matters until you are confident a child can move freely underneath it unassisted. Check manufacturer guidance carefully for any child, and when in doubt, ask a health professional before using one with a young child.
The mistakes worth avoiding
Choosing a blanket that is far heavier than the ten percent guideline suggests, assuming heavier automatically means more calming, usually backfires into something restrictive rather than soothing. Picking minky or plush fabric without considering how warm you already run at night leads to a blanket left folded at the end of the bed most of the year. Buying without checking washing instructions first, then discovering the whole blanket cannot fit in a standard machine, is an avoidable frustration covered by choosing a removable cover from the start.

Quick questions
Can a weighted blanket be too heavy?
Yes, and it is a genuine risk worth taking seriously. A blanket too heavy for your body weight can feel restrictive rather than calming, make moving underneath it difficult, and in the case of children carries real safety concerns. Staying close to the roughly ten percent of body weight guideline is the safer approach.
Are weighted blankets suitable for hot sleepers?
They can be, with the right fabric choice. Cotton or a dedicated cooling fabric like bamboo will serve a hot sleeper far better than minky or plush, which trap more heat. The weight itself does not inherently make a blanket warmer, the fabric covering the fill does most of that work.
Do weighted blankets work for everyone?
No, response varies genuinely between individuals. Many people find the pressure calming, and some find it uncomfortable or unnecessary. It is worth trying one with a return policy in place if possible, rather than assuming it will suit you simply because it works well for others.
