Most blankets can be dried in a dryer on low heat as long as there is room for it to tumble freely, though weighted and electric blankets are the main exceptions.
A soaked blanket feels like it will never dry on a rack, which is exactly why the dryer question comes up so often.
The size of the blanket relative to your dryer drum matters as much as the fabric itself, since a blanket that cannot tumble will not dry evenly no matter the heat setting.
Use a large-capacity dryer if you have access to one, or dry oversized blankets at a laundromat where drums are bigger and give the fabric more room to tumble. Add two or three clean tennis balls or dryer balls to keep the fabric moving and prevent it from clumping into one damp wad in the center.
Expect 45 to 90 minutes on low to medium heat depending on thickness, checking and repositioning the blanket every 20 to 30 minutes so all sides get even airflow. Pull it out slightly damp and finish air-drying over a rack or shower rod to avoid overheating the fabric during a long final stretch of high heat.
Cramming a king-size comforter into a standard home dryer is the biggest one, since it just spins in a ball without ever drying the center, and the outside can even test dry while the middle stays damp for days. High heat on synthetic fill can also melt or flatten fibers permanently, leaving cold spots and an uneven, lumpy feel that will not fluff back out.
Look for a tumble-dry symbol with a dot count indicating heat level, one dot means low heat only, which is the safest choice for most blankets unless the label specifically allows medium or high. A crossed-out square with a circle means no machine drying at all, which shows up on many wool and specialty-fill blankets even when the rest of the item looks machine washable. When a tag is missing or worn off entirely, treat the blanket as delicate and default to low heat or air drying rather than guessing at a hotter setting.
Most blankets dry fine at home as long as the dryer has room for them to move and the heat stays low. For oversized or electric blankets, check the label first, since some genuinely need air-drying only.
A twin or full-size comforter usually fits, but queen and king sizes often need a large-capacity machine at a laundromat to dry evenly.
Usually 45 to 90 minutes on low to medium heat, depending on thickness and fill. Check every 20 to 30 minutes and reposition it to dry evenly.
Check the label first. Many weighted blankets are air-dry only, since heat can damage the glass or plastic beads used for weight.
It likely did not dry all the way through. Squeeze the thickest part; if it feels damp or cool, run another cycle or finish air-drying.
