Dryer Symbols Explained: What Each One Means for Your Clothes
Dryer Symbols Explained: What Each One Means for Your Clothes
You’re doing laundry and checking the care label on a new sweater. You see a square with a circle inside and two dots. You have no idea if that means medium heat, low heat, or don’t dry at all. You could guess, but guessing wrong can shrink, warp, or ruin the garment. Dryer symbols are a standardized system that tells you exactly how to dry each item. Once you know the basics, you can read any dryer symbol in seconds.
Dryer symbols are standardized icons on clothing care labels that indicate how to dry a garment without damaging it. The basic symbol is a square, which represents drying. A circle inside the square means tumble dry. Additional marks (dots, lines, crosses) indicate heat level, cycle type, and restrictions.
To read dryer symbols, identify the basic shape (square for drying, square with circle for tumble dry), then look for additional marks: dots indicate heat level, lines under the symbol indicate cycle type, and a cross means don’t do it. When in doubt, air dry.
Tumble Dry Symbols (Square with Circle)
The most common dryer symbols are variations of the square with a circle inside. Dots inside the circle indicate heat level.
| Symbol | Meaning | What to Do |
|---|---|---|
| Square with circle, no dots | Tumble dry, normal | Use any heat setting |
| Square with circle, one dot | Tumble dry, low heat | Use low heat (125F) |
| Square with circle, two dots | Tumble dry, medium heat | Use medium heat (140F) |
| Square with circle, three dots | Tumble dry, high heat | Use high heat (150F+) |
| Square with circle, solid circle | Tumble dry, no heat | Use air fluff setting |
Cycle Type Symbols (Lines Under the Square)
Lines under the square indicate the cycle type, just like washing symbols.
| Symbol | Meaning | What to Do |
|---|---|---|
| Square with circle, no lines | Normal cycle | Use regular dryer setting |
| Square with circle, one line under | Permanent press cycle | Use Perm Press setting |
| Square with circle, two lines under | Gentle or delicate cycle | Use Delicates setting |
Do Not Tumble Dry (Crossed-Out Symbol)
A square with a circle that has a cross (X) over it means do not tumble dry. This garment must be air dried.
What to do instead:
- Line dry (hang on a clothesline)
- Flat dry (lay flat on a drying rack)
- Drip dry (hang while dripping wet)
Why some garments can’t be tumble dried:
- Heat can shrink wool and silk
- Tumbling can stretch delicate knits
- Heat can damage elastic in activewear
- Heat can set wrinkles in some synthetics
Air Drying Symbols (Square Without Circle)
When the square has no circle inside, it means air dry (no machine drying).
| Symbol | Meaning | What to Do |
|---|---|---|
| Square with one curved line at top | Line dry | Hang on a clothesline or hanger |
| Square with three vertical lines | Drip dry | Hang dripping wet, don’t wring |
| Square with one horizontal line in middle | Flat dry | Lay flat on a drying rack |
| Square with two diagonal lines in top left | Dry in shade | Keep out of direct sunlight |
| Square with one horizontal line at top | Line dry (horizontal line) | Hang on a rod or line |

Tips for Following Dryer Symbols
When in doubt, air dry. Air drying won’t damage any fabric. If you’re not sure what a symbol means, skip the dryer and hang or lay flat to dry.
Check the label before buying. If a garment says do not tumble dry and you always use the dryer, think twice before buying it.
Sort laundry by drying requirements. Don’t dry items that need low heat with items that need high heat. Sort by drying requirements, not just washing requirements.
Clean the lint screen before every load. A clogged lint screen reduces drying efficiency and can cause overheating, which can damage clothes.
Use dryer balls. Wool dryer balls reduce drying time and static without the waxy residue of dryer sheets.
Don’t over-dry. Over-drying creates static electricity and can damage fabric fibers. Use the moisture-sensing setting if your dryer has one.
Use the cool-down cycle. The cool-down cycle at the end of the drying cycle reduces wrinkles and static. It’s especially important for permanent press items.
Products That Help with Drying
For maintaining your dryer: Clean the lint screen before every load. Use affresh Washing Machine Cleaner for your washer to ensure clean clothes go into the dryer.
For reducing static: Use wool dryer balls instead of dryer sheets. Dryer sheets can leave a residue on the dryer’s moisture sensors.
For air drying: Use a drying rack or clothesline. Drying racks are inexpensive and fold flat for storage.
