When you’re shopping for bedding, knowing what size is a full size blanket can save you a lot of hassle. It’s the key to ensuring your bed looks neat, feels comfortable, and stays cozy all night.
A full size blanket, also called a double blanket, is designed to fit a standard full-size mattress. But there’s more to it than just the basic dimensions. The right blanket size affects warmth, style, and how well it stays in place. Let’s break down everything you need to know to choose perfectly.
What Size Is A Full Size Blanket
The standard dimensions for a full size blanket are typically 80 inches wide by 90 inches long. This size is meant to drape over the sides and foot of a full mattress, which usually measures 54 inches by 75 inches. The extra fabric ensures you have enough coverage, especially if you share the bed or move around in your sleep.
Why the Extra Inches Matter
You might wonder why the blanket is so much bigger than the mattress. Those extra inches are crucial for practical comfort. They allow the blanket to hang over the edges, which helps keep you tucked in and prevents drafts. It also gives a more finished, layered look to your bed’s appearance.
- For Draping: A good overhang is about 13 inches on each side and 15 inches at the foot.
- For Tucking: If you prefer a tight, tucked-in look, you’ll need the extra lenght to secure it under the mattress.
- For Sharing: The width provides adequate coverage for two average-sized adults, though it can be cozy.
Comparing Full Blankets to Other Sizes
It’s easy to get blanket sizes confused. Here’s a quick comparison to keep things straight.
- Twin Blanket: Usually 66″ x 90″. Significantly narrower than a full.
- Full Blanket: 80″ x 90″. Our standard size.
- Queen Blanket: Usually 90″ x 90″ or 90″ x 95″. Wider and sometimes longer.
- King Blanket: Typically 108″ x 90″ or 108″ x 100″. Much wider for a king bed.
Using a queen blanket on a full bed is a common hack for more drape, while a twin blanket will be too small and leave the edges exposed.
How Mattress Depth Affects Blanket Fit
Modern mattresses, especially pillow-tops or those with thick toppers, can be much deeper than older models. A standard mattress might be 9-12 inches deep, but many are now 14-16 inches or more.
If your mattress is on the thicker side, a standard 80×90 blanket might have a shorter drop than you’d like. In this case, you might want to consider a “deep pocket” or “extra drop” blanket style, or simply size up to a queen blanket for better coverage.
Choosing the Right Full Size Blanket Material
The material of your blanket determines its warmth, weight, feel, and care requirements. Your choice should match your personal needs and the climate you live in.
Cotton Blankets
Cotton is a classic, breathable choice. It’s great for year-round use, especially in warmer climates or for people who sleep hot. Cotton blankets are generally easy to wash and come in various weaves.
- Pros: Breathable, easy to care for, hypoallergenic options available.
- Cons: Doesn’t provide intense warmth on its own in very cold weather.
Wool Blankets
Wool is a natural insulator, perfect for cold winters. It wicks moisture away and can regulate temperature well. However, some people find certain wools to be itchy, so look for merino or cashmere blends for softness.
- Pros: Exceptionally warm, moisture-wicking, durable.
- Cons: Can be heavy, may require special cleaning, can be expensive.
Fleece Blankets
Fleece, made from polyester, is soft, lightweight, and very warm for its weight. It’s an affordable and low-maintenance option that dries quickly. It’s a favorite for adding a cozy layer.
- Pros: Lightweight, very warm, inexpensive, machine washable.
- Cons: Can pill over time, may generate static electricity.
Down and Down-Alternative Blankets
These blankets are filled with either natural down feathers or synthetic fibers. They provide loft and warmth without a lot of weight. They are ideal for those who want a fluffy, cloud-like layer.
- Pros: Lightweight yet warm, compressible, durable.
- Cons: Down requires special care, some people have allergies.
Step-by-Step Guide to Measuring Your Bed for a Blanket
If you’re unsure or have a non-standard bed frame, it’s best to measure. Here’s how to do it correctly.
- Measure Your Mattress: Use a tape measure to get the exact width and length of the top of your mattress.
- Measure Mattress Depth: Measure from the top of the mattress straight down the side to the bottom. This is the depth.
- Decide on Desired Drop: How far do you want the blanket to hang down the sides? A common drop is 10-15 inches. Multiply your desired drop by 2 (for both sides).
- Calculate Total Width: Add mattress width + (2 x desired drop). For a 54″ mattress with a 13″ drop: 54 + 26 = 80 inches.
- Calculate Total Length: Add mattress length + desired drop at foot + allowance for tucking (if wanted). For a 75″ mattress with a 15″ drop: 75 + 15 = 90 inches.
These calculations should give you the ideal blanket dimensions. If your numbers are close to 80×90, a standard full blanket is perfect.
Common Mistakes When Buying a Full Size Blanket
Avoid these pitfalls to ensure you get a blanket you’ll love for years.
Mistake 1: Ignoring Shrinkage
Many natural fabrics, like cotton and wool, can shrink in the wash. If a blanket is “pre-shrunk,” you’re safer. If not, you might consider sizing up slightly to account for this, especially if you plan to machine wash and dry it.
Mistake 2: Forgetting About the Comforter
If you use a duvet cover or comforter, remember that it goes over the blanket or instead of it. A duvet cover should fit your comforter snugly, so those dimensions are separate. Your blanket might be a decorative top layer or an extra warm layer underneath.
Mistake 3: Overlooking Weave and Weight
Two blankets with the same dimensions can feel completely different. A tightly woven cotton blanket is lighter and cooler than a heavy, napped fleece one. Think about the season and your personal sleep temperature when choosing.
Mistake 4: Assuming All “Full” Labels Are Equal
Always check the product’s specific dimensions. Some manufacturers might have slight variations, and “full” in one brand could be 78×88, while another is 82×92. The label is a guide, but the numbers are the truth.
Care and Maintenance for Your Blanket
Proper care extends the life of your blanket and keeps it looking and feeling it’s best.
Washing Instructions
Always check the care label first. Here are general guidelines:
- Cotton & Polyester: Usually machine washable in cool or warm water. Tumble dry on low.
- Wool: Often requires dry cleaning or a specific hand-wash/wool-wash cycle. Air dry flat.
- Down: Use a front-loading washer on gentle with a mild detergent. Dry thoroughly with tennis balls to break up clumps.
Storing Your Blankets
When not in use, store blankets in a cool, dry place. Avoid plastic bags, which can trap moisture and lead to mildew. Instead, use cotton storage bags or breathable boxes. For wool blankets, consider cedar blocks to deter moths.
FAQ Section
What is the difference between a full and a double blanket?
There is no difference. “Full” and “double” refer to the same bed and blanket size in modern terminology. The names are used interchangeably.
Can I use a queen blanket on a full bed?
Yes, you absolutely can. Using a queen blanket (90×90) on a full bed will give you more overhang on the sides, which can be preferable for taller people, couples, or those with a deeper mattress. It’s a popular choice for a more luxurious look.
How much should a full size blanket hang over the sides?
A good rule of thumb is for the blanket to hang 10 to 15 inches down each side of the mattress. This ensures it stays in place, covers the bed frame, and looks proportionally correct.
What size blanket for a full bed with two people?
A standard full blanket works, but it can be snug. For more comfort, sizing up to a queen blanket is a smart idea. The extra width (about 10 inches more) gives each person more coverage and reduces blanket-stealing.
Are full size and twin XL blankets the same?
No. A twin XL mattress is 39 inches wide by 80 inches long. A twin XL blanket is typically around 68×90, making it longer but much narrower than a full size blanket. They are not interchangeable.
Final Tips for Your Perfect Purchase
Now that you know what size is a full size blanket and all the factors involved, you can shop with confidence. Remember to consider your sleeping habits, your mattress depth, and the climate you live in. Don’t just grab the first blanket you see—take a moment to feel the fabric and read the label.
Investing in a well-made blanket that’s the right size will improve your sleep and your bedroom’s decor. It’s a simple upgrade that has a big impact on your daily comfort. With the right care, a good blanket can be a cozy companion for many years to come.
