What Size Is a Full Bed Blanket? | Standard Dimensions Explained

A full bed blanket measures 80 × 90 inches, the standard size for a full/double mattress.

If you’re shopping for a full bed blanket, the size you’ll see most often is 80 × 90 inches. That matches a full/double mattress, which runs 54 × 75 inches, and gives you enough overhang on the sides and foot of the bed for a proper drape. Some brands sell a larger full/queen option at 85 × 90 or even 90 × 90 inches when you want extra coverage.

The Standard Full Blanket Size

The most common blanket size for a full bed is 80 × 90 inches. That’s the figure the Sleep Foundation uses in its bedding guides, and it’s what most manufacturers list for a standard full/double fit.

A full/double mattress is 54 × 75 inches, so an 80 × 90 blanket gives you roughly 13 inches of overhang on each side and about 7.5 inches at the foot. That’s enough to tuck under the mattress or let the blanket drape naturally over the edges.

Some guides also list 85 × 90 inches or 90 × 90 inches as full/queen sizes. These roomier options work on a full bed with extra overhang, and they’ll also fit a queen mattress — just with less drape than a true queen blanket.

Full vs. Full/Queen: What’s the Difference?

Manufacturers don’t follow one industry-wide blanket standard, so labeled sizes vary from brand to brand. The practical difference comes down to width:

• 80 × 90 inches — the standard full size, built for a 54-inch-wide mattress
• 85 × 90 inches — a roomier full/queen option with extra side overhang
• 90 × 90 inches — the largest full/queen size, often used on queen beds, too

The most common mistake shoppers make is treating “full,” “double,” and “full/queen” as the same thing. A true full blanket is 80 × 90; a full/queen runs wider. If you want a snug, tailored look on a full bed, stick with 80 × 90. If you prefer a generous drape or plan to use the blanket on a queen later, the larger options give you more flexibility.

How to Choose the Right Full Blanket Size

Before you buy, measure your mattress and decide how much overhang you want. A full mattress is 54 × 75 inches, and most people want at least 8–12 inches of drape on each side. That makes 80 × 90 the safe default.

Consider a full/queen size if you share the bed and want more blanket to pull up, or if you like the blanket to pool on the floor. Just remember that a 90 × 90 blanket on a full bed will have a lot of excess fabric — which some people love and others find heavy.

Season and material matter, too. A heavier blanket traps more warmth regardless of size, so a lighter full-size option may suit warmer months better than a thick full/queen.

FAQs

Will a full-size blanket fit a queen bed?

A standard 80 × 90 full blanket will fit a queen mattress (60 × 80 inches), but with minimal overhang — you’ll get about 10 inches on each side and little at the foot. It works in a pinch, though a true queen blanket (90 × 90 or larger) looks and feels better on a queen bed.

Is a full blanket the same as a double blanket?

Yes, “full” and “double” refer to the same mattress and blanket size. Both describe a 54 × 75-inch mattress, and an 80 × 90-inch blanket fits it. The terms are interchangeable in most bedding catalogs, though some manufacturers use “full/queen” for a larger in-between size.

How much overhang should a full bed blanket have?

Most people prefer 8–12 inches of overhang on each side so the blanket drapes naturally over the mattress edges. The standard 80 × 90 size delivers roughly that on a full bed. If you want the blanket to reach closer to the floor, step up to a full/queen size at 85 × 90 or 90 × 90 inches.
