Quick Answer: For a standard single bed (38 x 75 inches), the recommended blanket size is 66 x 90 inches (168 x 229 cm). This gives about 14 inches of overhang on each side and adequate foot coverage. If you prefer more drape or plan to tuck the blanket under the mattress, look for 72 x 96 inches or a size labelled "full."

Buying a blanket for a single bed seems straightforward until you realise that "twin size" blankets vary by 4 to 6 inches across different manufacturers, and what fits snugly on one single mattress hangs off the floor on another. This guide cuts through the sizing confusion with specific numbers and practical guidance for single bed blankets in Canadian homes.
Single Bed Dimensions in Canada
Before sizing a blanket, know your mattress. In Canada, a single bed (also called a twin) has a standardised mattress dimension of 38 inches wide by 75 inches long (97 cm x 191 cm). This is the starting point for all blanket sizing calculations.
There is one important variation: the twin XL. A twin XL mattress has the same 38-inch width but extends to 80 inches long (203 cm). Twin XL mattresses are common in student dormitories, bunk beds in guest rooms, and purpose-built single beds for taller adults. If your single bed is a twin XL, you need to account for the extra 5 inches of length when sizing a blanket.
| Mattress Type | Dimensions (inches) | Dimensions (cm) | Common Uses |
|---|---|---|---|
| Twin / Single | 38 x 75 | 97 x 191 | Children's rooms, guest rooms, adult singles |
| Twin XL | 38 x 80 | 97 x 203 | Dorm rooms, tall adults, bunk beds |
Both sizes are narrow compared to a double or queen, which affects how blanket drape looks and functions. A blanket that fits beautifully on a queen bed will have substantial pooling on the floor if used on a single mattress. Sizing accurately matters more with single beds than with larger mattresses precisely because the narrowness amplifies any sizing error.
Single Beds at Mattress Miracle
We carry single and twin XL mattresses in our showroom on West Street in Brantford. The most common customer question we get about single bed sizing is from parents setting up children's rooms or from adults moving into a smaller space and downsizing from a queen. In both cases, the same principle applies: measure the mattress, then add the drape you want. A blanket that reaches the top of the box spring on both sides requires about 20 inches of total width beyond the mattress surface. Brad often walks customers through this calculation in the showroom so they leave with the right size rather than returning a blanket that turned out too short.

Standard Blanket Size for a Single Bed
The standard recommended blanket for a single bed is 66 x 90 inches (168 x 229 cm). This is the most common "twin" or "single" blanket size produced by Canadian and North American manufacturers.
With a 38 x 75-inch mattress, a 66 x 90-inch blanket provides:
- 14 inches of width overhang on each side (66 - 38 = 28 inches total, divided by 2)
- 15 inches of length overhang below the foot of the bed (90 - 75 = 15 inches)
This is sufficient drape for a tidy appearance without the blanket touching the floor, assuming a standard mattress height of 10 to 12 inches plus a box spring or platform base. If your bed is on a higher platform or includes a tall box spring, you may want a larger blanket to ensure adequate coverage.
For a complete reference including all standard blanket sizes, see our detailed guide on blanket sizes in inches, which covers every standard dimension from throw to king in both inches and centimetres.
When to Go Larger
A 66 x 90-inch blanket is correct for most single beds, but there are situations where sizing up to a double (80 x 90 inches) or even a queen (90 x 90 inches) makes more sense:
- Taller sleepers: If you are taller than 5'10" and your feet approach the mattress edge at the foot, a longer blanket ensures you do not wake up cold from feet exposure.
- Active sleepers: People who move significantly during sleep benefit from extra blanket width. A double blanket on a single bed provides enough coverage to remain covered through most sleeping positions.
- Tucked-in preference: If you prefer tucking the blanket under the mattress at the foot and sides, you need additional length and width to account for the tucked portion. A double blanket (80 x 90 inches) on a single bed gives you approximately 21 inches of width overhang per side, enough to tuck securely under a standard mattress.
Understanding Overhang and Drape
Overhang refers to how much blanket extends beyond the edge of the mattress on each side and at the foot. How much overhang you want is partly practical and partly aesthetic.
Practical Overhang
For functional warmth and coverage without getting out of bed to retrieve a slipped blanket, a minimum of 8 to 10 inches of overhang per side is recommended. This keeps the blanket accessible when you shift position during the night and provides enough coverage at the edges to prevent cold air from entering at the sides.
A 66 x 90-inch blanket on a 38 x 75-inch mattress provides 14 inches per side, which exceeds this minimum. This is deliberate. Blanket manufacturers know that users shift during sleep, and the extra width keeps the blanket from pulling fully to one side with ordinary movement.
Aesthetic Drape
A blanket that extends to the top of the box spring or platform base looks intentional and tidy. One that just barely covers the mattress surface looks small. One that pools on the floor looks oversized. For a single bed with a standard mattress and box spring height of about 20 to 25 inches total, a 66 x 90-inch blanket with 14 inches of side overhang will typically reach the top of the box spring, which is the conventional "tidy" look.
Sizing for Children's Single Beds
Children's single beds present a few specific considerations that adult beds do not.
Safety Considerations for Young Children
Children under 2 should not have loose blankets in their sleep space at all, per guidelines from the Canadian Paediatric Society. For children 2 and older transitioning from a crib, a smaller blanket (around 50 x 60 inches) is easier for a young child to manage, less likely to become tangled, and proportionate to a small body that does not reach the full length of a single mattress anyway.
Growing Into a Standard Size
By age 6 or so, most children on a standard single mattress can use a full 66 x 90-inch twin blanket comfortably. The benefit of moving to a standard size is longevity: a quality blanket in the right size for a single bed can serve a child through their teen years without needing replacement for sizing reasons.
Foot Temperature and Children's Sleep Quality
Research on sleep physiology consistently identifies foot warmth as a key variable in sleep onset. Krauchi (2007) in Sleep Medicine Reviews identified that peripheral vasodilation (warming of the extremities) triggers the core body temperature drop that initiates sleep. Children whose feet become cold during the night often wake from discomfort without understanding why. Choosing a blanket that provides consistent foot coverage throughout the night, sized so it does not pull away from the foot of the bed when the child moves, is a practical step toward more settled sleep for school-age children.
Twin XL: Do You Need a Different Blanket?
A twin XL mattress is 5 inches longer than a standard twin. That extra length matters when calculating blanket fit.
With a standard 66 x 90-inch blanket on a twin XL (38 x 80 inches):
- Width overhang: still 14 inches per side (unchanged)
- Length overhang at foot: 90 - 80 = 10 inches (down from 15 inches)
Ten inches of foot overhang is workable for most people. If you tuck the blanket under the mattress at the foot, however, a standard twin blanket on a twin XL will not have enough length to tuck and still cover your feet. In that case, look for blankets labelled "twin XL" or sized at 66 x 96 inches, which restores adequate foot coverage even when tucked.
Choosing the Right Material for a Single Bed Blanket
Size gets you coverage. Material determines warmth and how well the blanket performs across seasons.
Material Guide for Single Bed Blankets
- Cotton flannel: Warm, breathable, softens with washing. Good year-round choice for Ontario bedrooms. Machine-washable and durable for regular use.
- Wool or Merino wool: Best warmth-to-weight ratio. Thermoregulates well through winter nights. Requires gentler washing but lasts significantly longer than synthetics.
- Fleece: Easy care, very warm for the weight. Practical for children's rooms where easy-wash durability matters. Less breathable than natural fibres.
- Cotton percale weave: Lighter weight than flannel. Better for spring and summer use, or for people who sleep warm. Breathes well and is extremely durable.
- Bamboo blend: Very breathable and soft. Good for warm sleepers or summer use. Less common at standard retail price points but available through specialty bedding shops.
If you are choosing a blanket for a child's room, easy washing should be a top priority alongside size. Flannel and fleece blankets in twin size handle frequent washing without significant degradation, which matters when a child has stomach bugs, spills drinks in bed, or goes through any of the other scenarios that produce emergency bedding washes.
For adults on a single bed, the considerations are the same as for any bed size, just in a smaller format. If you want to understand how blanket sizes scale across all bed sizes, our guide on blanket sizes in inches has a full size chart. And if the mattress itself is due for consideration, our guide to blanket sets covers how bedding layers work together for better sleep.

What size blanket fits a single bed?
A standard single (twin) mattress in Canada measures 38 x 75 inches. The recommended blanket size for a single bed is 66 x 90 inches, which provides approximately 14 inches of overhang on each side and 15 inches at the foot. If you prefer more drape or plan to tuck the blanket under the mattress, look for a size closer to 72 x 96 inches or a double/full size blanket (80 x 90 inches).
Is a twin blanket the same as a single blanket?
Yes. In Canada, "twin" and "single" refer to the same mattress and blanket size. Labels may use either term. A twin blanket and a single blanket are functionally identical at approximately 66 x 90 inches. Always verify actual dimensions on the product listing, as some manufacturers vary their measurements while using the same size label.
Can I use a double blanket on a single bed?
Yes, and it is a practical choice for active sleepers or taller adults. A double/full blanket (approximately 80 x 90 inches) on a single bed gives you about 21 inches of overhang per side, enough to tuck in securely while still maintaining generous coverage. The bed will look somewhat over-blanketed, but the functional comfort is good.
What size blanket is best for a child's single bed?
For children aged 2 to 5, a 50 x 60-inch blanket is manageable and proportionate to a young body on a single mattress. For school-age children (6 and up), a standard twin blanket at 66 x 90 inches works well and will last through their teen years without needing to be replaced for size. Ensure adequate foot coverage, as cold feet are a common cause of night waking in children.
What is a twin XL blanket and do I need one?
A twin XL mattress is 38 x 80 inches, 5 inches longer than a standard twin. A standard 66 x 90-inch blanket still covers a twin XL adequately for most people (10 inches of foot overhang remains). If you tuck the blanket under the mattress at the foot, look for twin XL blankets labelled 66 x 96 inches or larger to maintain adequate foot coverage after tucking.
