Dryer symbols
Every drying instruction on a tag is a square. What sits inside it tells you whether the dryer is welcome — and if it isn’t, how to hang the thing instead.
The square is the container for every drying instruction. A circle inside it means the dryer is allowed, and dots inside that circle set the heat: one dot low, two medium, three high. A circle filled in solid means air only, no heat at all. Bars underneath slow the drum down — one bar is the permanent press setting, two is gentle. An X through the square and circle means keep the garment out of the dryer entirely.
Squares with no circle in them are the air-drying half of the family: a sagging curve for line dry, three vertical lines for drip dry, one horizontal line for dry flat, and two short diagonals in the top-left corner for dry in shade. That last one never travels alone — it rides along with line dry, drip dry, or dry flat to add “out of direct sun” to whichever you were already given. One naming note while you are here: “tumble dry” only means machine drying in a rotating drum. US tags and machine panels usually say “dry,” UK and international tags say “tumble,” and it is the same appliance in your laundry room.
-
Tumble dry · square with a circle
Tumble drying is fine — any heat, unless dots inside the circle say otherwise.
If you ignore it: The risk lives in the dots: heat is what shrinks, and the plain symbol means the fabric can take it.
-
Tumble dry, no heat · square with a filled circle
Tumble dry on air only — no heat at all.
If you ignore it: Any heat setting risks shrinking or melting what this symbol protects — the drum is fine, the heater is not.
-
Tumble dry low · square with a circle and one dot
Tumble dry on low heat.
If you ignore it: Medium and high heat shrink elastics and knits a little more with every load — low is the ceiling here.
-
Tumble dry medium · square with a circle and two dots
Tumble dry on medium heat.
If you ignore it: High heat is the only setting this rules out; cooler is always fine.
-
Tumble dry high · square with a circle and three dots
Tumble dry on high heat — the fabric can take your dryer's hottest setting.
If you ignore it: Nothing to ignore — high is the ceiling and everything below it is allowed.
-
Tumble dry, permanent press · square with a circle, one bar beneath
Tumble dry on the permanent press setting — medium heat with a cool-down at the end.
If you ignore it: Skipping the cool-down sets wrinkles as the load sits hot — the exact thing this cycle prevents.
-
Tumble dry, gentle · square with a circle, two bars beneath
Tumble dry on the gentle cycle — low heat and gentler tumbling.
If you ignore it: A normal cycle's heat and tumble action is exactly what gradually wears out whatever earned these bars.
-
Do not tumble dry · square with a circle, crossed out
Keep it out of the dryer — air dry instead.
If you ignore it: One hot cycle can shrink it a full size or melt any elastic and glue in it; this is the most expensive symbol to ignore.
-
Line dry · square with a hanging curve
Hang it on a line or bar to dry.
If you ignore it: It usually pairs with a no-tumble warning — the dryer, not the clothesline, is what it's steering you from.
-
Drip dry · square with three vertical lines
Hang it up soaking wet and let it drip — no wringing or spinning first.
If you ignore it: Wringing or spinning first creases fabrics that are meant to smooth themselves out under their own water weight.
-
Dry flat · square with a horizontal center line
Lay it flat on a towel or rack to dry.
If you ignore it: Hanging a wet sweater stretches it under its own weight — shoulders and length never come back.
-
Dry in shade · square with two diagonal lines in the corner
Dry it out of direct sunlight — it rides along with a line-dry or flat-dry symbol.
If you ignore it: Direct sun fades the dye while the garment is wet, when it is most vulnerable.
-
Do not dry · empty square crossed out
Don't dry it yourself by any method — it appears on garments that shouldn't be home-washed either.
If you ignore it: This symbol travels with do-not-wash; if you're seeing it, the whole job belongs to a professional.
Questions people actually ask
What do the dots inside the dryer circle mean?
Heat. One dot is low, two is medium, three is high, and a circle filled in solid means no heat at all — the setting your machine may call air fluff. The dots are a ceiling, so anything cooler is always within the tag.
What does an X through the drying square mean?
Two different things, depending on what is inside the square. A crossed-out square with a circle in it means do not tumble dry — air dry instead. An empty square crossed out means don’t dry it yourself by any method, and it usually sits beside a crossed-out washtub.
Can I hang something up to dry when the tag says tumble dry?
Yes. A tumble dry symbol is permission, not an order, and air drying is gentler than any dryer setting. It doesn’t work in the other direction: a line dry, drip dry, or dry flat symbol is telling you the dryer is off the table.
What is the difference between line dry, drip dry, and dry flat?
Line dry means hang it up after the water has been pressed or spun out. Drip dry means hang it soaking wet with no wringing or spinning first, so the water weight pulls the wrinkles out. Dry flat means lay it on a towel or rack so nothing stretches under its own weight.
