How do I calculate the right weight for a weighted blanket?

The standard guideline recommended by most occupational therapists in Australia is to choose a blanket that weighs approximately 10% of the user's body weight. For example, a 25 kg child would suit a 2–2.5 kg blanket, while a 70 kg adult would use a 7 kg blanket. Always round down when between sizes, particularly for children. For users who are very sensitive to pressure, starting with a lighter weight and increasing gradually can help the body adjust more comfortably.

What is the difference between glass bead and poly pellet weighted blankets?

Glass micro-beads are the premium fill choice: smaller, denser, and quieter than poly pellets, they distribute weight more evenly and create a smoother, more consistent feel across the blanket surface. Poly pellets are plastic beads that cost less to manufacture — they provide the therapeutic weight but can feel slightly lumpy, may produce rustling sounds, and tend to be less durable over repeated washings. For sensory-sensitive individuals, glass bead blankets are almost always preferred by occupational therapists due to their superior weight distribution and absence of noise.

Should a weighted blanket cover the whole bed or just the body?

A weighted blanket should ideally be sized to cover only the user's body — not the entire mattress surface. Unlike a regular doona, the blanket should not overhang the sides of the bed, as overhanging weight can cause the blanket to slide off the mattress and pulls the weight away from where it is therapeutically useful. Children's blankets are typically sized around 90 x 120 cm to 100 x 150 cm, while adult single throw blankets are approximately 120 x 180 cm. Choose the smallest size that comfortably covers the user's body from shoulders to feet.

How long does it take to get used to sleeping with a weighted blanket?

Most users — adults and children alike — require 1–2 weeks of consistent use before they feel fully comfortable sleeping with a weighted blanket all night. In the first few nights, some users find the weight novel or slightly unusual, and may initially remove the blanket during the night. This is completely normal. Occupational therapists recommend starting with the blanket for shorter periods during the day (such as during reading or screen time) before transitioning to overnight use, which allows the sensory system to adjust gradually to the new input.

Can I use a weighted blanket in Australian summer?

Yes, with the right choice of outer fabric. In Australia's warmer climates, it is important to select a weighted blanket with a breathable outer fabric — cotton or bamboo covers are far more suitable for summer use than minky fleece, which traps heat. Some Australian brands offer separate summer and winter cover sets, allowing you to keep the inner weighted insert and swap covers seasonally. In very hot weather, a lightweight cotton cover combined with air conditioning can make a weighted blanket perfectly comfortable year-round. Glass bead fill also tends to sleep cooler than poly pellet fill.

Are there weighted blankets suitable for hot Australian climates?

Absolutely. Look for blankets that use natural breathable fibres such as 100% cotton, organic cotton, or bamboo-blend outer covers. These fabrics allow air to circulate around the fill pockets, preventing heat build-up. Avoid thick fleece or minky covers if you live in Queensland, Northern Territory, or coastal NSW and Victoria where summers are hot and humid. Several Australian brands have developed specific summer-weight ranges with lighter fill and cooling covers that maintain the therapeutic pressure benefit without the insulating warmth of standard winter-weight blankets.

Introduction: Why Choosing the Right Weighted Blanket Matters

With so many weighted blankets now available in Australia — from premium locally made options to affordable imported alternatives on Amazon Australia — choosing the right one can feel overwhelming. The wrong choice is not just a financial issue: a blanket that is too heavy, too hot, or made from an irritating fabric can put a sensory-sensitive child or adult off weighted blankets entirely, denying them a tool that might otherwise significantly improve their sleep, regulation, and wellbeing.

This guide walks you through every factor that matters when selecting a weighted blanket in Australia, drawing on occupational therapy guidelines and practical experience with Australian families. Whether you are buying for a child with autism, an adult managing anxiety, or simply exploring better sleep options, this guide will help you make a confident, informed decision.

Step 1 — Choose the Right Weight

Weight is the single most important factor in a weighted blanket. The universally applied guideline is approximately 10% of the user's body weight. This ratio is not arbitrary: it represents the level of pressure at which the body's mechanoreceptors (pressure-sensitive nerve endings in the skin) are stimulated without triggering a defensive sensory response. Too light, and the blanket provides insufficient input to calm the nervous system. Too heavy, and it becomes uncomfortable, restricts movement, and may increase rather than reduce anxiety.

Use this simple calculation: (body weight in kg) ÷ 10 = recommended blanket weight in kg. Round to the nearest available size, always preferring the lighter option when between sizes. Most Australian brands offer blankets in 2 kg increments, so you should be able to get close to the ideal weight for most users.

Step 2 — Select the Right Size

Weighted blanket sizing works differently to regular bedding. You want a blanket sized to cover the user's body — not the bed. A blanket that hangs over the mattress edge loses therapeutic value because the overhanging weight pulls the blanket sideways rather than downwards onto the body. As a practical guide:

Toddlers and preschoolers (ages 3–5): approximately 90 x 120 cm
Primary school children (ages 5–12): approximately 100 x 150 cm
Teenagers and adults (under 175 cm tall): approximately 120 x 180 cm
Tall adults (175 cm+): approximately 150 x 200 cm (queen size)

If your child is between size ranges, choose the larger size — they will grow into it, and a slightly oversized blanket causes fewer problems than one that does not cover the full body length.

Step 3 — Understand Fill Types

The two main fill types available in Australia are glass micro-beads and poly pellets. Understanding the difference is essential for making the right choice, particularly if the user has sensory sensitivities.

Glass micro-beads are tiny, spherical beads approximately 1 mm in diameter. They are dense, smooth, and silent. Because they are so small, they distribute evenly within each sewn pocket, creating a consistent, smooth pressure surface. Glass bead blankets tend to drape more naturally over the body and feel less lumpy than poly pellet alternatives. They are the preferred choice among Australian occupational therapists for sensory-sensitive individuals.

Poly pellets are small plastic pellets — approximately 3–5 mm in size. They are less expensive to manufacture and widely used in budget-tier blankets. They work effectively as a weight source but can shift within pockets, feel slightly uneven, and produce a quiet rustling sound when the blanket moves. For children with auditory sensitivities or tactile sensitivities to uneven surfaces, poly pellets may be less suitable.

Step 4 — Choose the Right Cover Fabric

Cover fabric choice is often underestimated but can be the deciding factor in whether a sensory-sensitive person will actually use the blanket. The three main options available in Australian weighted blankets are:

Cotton: Breathable, durable, and machine washable. Excellent for warm Australian climates. The best all-round choice for year-round use, particularly in Queensland, NSW, and Western Australia where summers are hot.
Minky / fleece: Soft, plush, and warm. Excellent for winter use in cooler southern states (Victoria, Tasmania, ACT). Not recommended for summer use without air conditioning due to heat retention.
Bamboo-cotton blend: The premium breathable option. Bamboo fibres naturally regulate temperature and wick moisture, making these covers comfortable in most Australian climates year-round. Generally more expensive but worth it for users who sleep hot.

Step 5 — Confirm Washability

For a weighted blanket to be a practical part of daily family life in Australia, it needs to be regularly washable. Look for blankets that are explicitly rated as front-loader machine washable. Top-loader machines with central agitators can damage the internal pocket stitching that keeps the fill evenly distributed, so front-loader compatibility is the key specification to check.

For blankets in the heavier adult weight range (7–9 kg), check your washing machine's maximum load capacity. Many standard home front-loaders are rated for 7–9 kg loads, which means a fully wet 9 kg blanket may exceed the machine's safe operating weight. In this case, a local laundromat with commercial front-loaders (typically rated at 15–20 kg) is the practical solution.
