How Much Does Carpet Weigh?
Weight per square foot, per square yard, and by the roll
Torn-out carpet weighs about 0.5 to 0.8 pounds per square foot for a typical synthetic pile, or roughly 5 to 7 pounds per square yard. Add the padding underneath and a room's worth gets close to a pound per square foot. Wool and thick commercial carpet run heavier still.
Carpet weight at a glance
Figures are for dry residential carpet pulled up for disposal. Wet or flooded carpet weighs far more.
Weight by carpet type
Carpet weight tracks two things: the fiber and the backing. Installers quote fiber alone as "face weight," measured in ounces per square yard, and most residential carpet lands between 35 and 60 ounces. But the number that matters for disposal is the whole thing, fiber plus the primary and secondary backing, rolled up and tossed. Those totals are below, heaviest fiber types at the bottom.
| Type (with backing) | lb/yd² | lb/ft² |
|---|---|---|
| Builder-grade synthetic (polyester, olefin) | 5–7 | 0.55–0.8 |
| Mid to high-grade nylon, dense pile | 7–10 | 0.8–1.1 |
| Wool | 12–20 | 1.3–2.2 |
| Carpet padding (rebond, typical) | 2–4 | 0.2–0.45 |
Padding is the sleeper. It's light per square yard, but a typical rebond pad adds a third to half of the carpet's own weight, and it's every bit as bulky. Pull a room of carpet and pad together and you've roughly doubled what you're hauling out.
Loose weight in a dumpster
Once it's ripped up and piled loose, carpet settles at a low density because it traps so much air. These are the federal figures for construction and demolition debris.
| Material (loose) | lb / cubic yard |
|---|---|
| Carpet | 147 |
| Carpet padding | 62 |
At 147 pounds per cubic yard, a full 10-yard dumpster of nothing but carpet is under 1,500 pounds, well within any container's limit. That tells you what to expect: with carpet, you run out of room long before you run out of weight.
Pulling up flooded or water-damaged carpet? Weigh it differently.
Wet carpet and pad soak up water like a sponge and can weigh two to three times their dry weight. A load that would ride light dry can push a small dumpster toward its cap. If the carpet came out of a basement flood or a leak, size up on weight, not just volume, and drain or let it dry before loading if you can.
What this means when you rent a dumpster
Carpet is a volume problem, not a weight problem. It's light, but it springs back and refuses to compress, so it eats container space faster than almost anything else you'll load. A whole-house re-carpet, say 1,500 to 2,000 square feet of carpet and pad, is only 1,500 to 2,500 pounds, yet it can fill a 15-yard dumpster on bulk alone.
How you load it decides how much fits. Cut the carpet into strips three or four feet wide as you pull it, then roll each strip tight and tape it. Loose, balled-up carpet bridges across the top of a dumpster and leaves dead air underneath; tight rolls stack flat and lie down. The same goes for pad, which tears into sheets and folds down small.
For a single room or two, we'd skip the dumpster entirely. Rolled and tied, one room of carpet is a few manageable bundles that fit in a pickup or that many curbside bulk pickups will take. Renting a container for 200 square feet of carpet is paying for space you won't come close to using. Save the dumpster for a whole floor, a full house, or a job where carpet is one part of a bigger tear-out.
Where these numbers come from
Face weight and carpet construction terms follow the Carpet and Rug Institute, the industry's standards body, which defines face weight as the fiber weight in ounces per square yard. The installed weights in the table add typical primary and secondary backing to those fiber figures, then convert to pounds per square foot for flooring math.
The loose debris densities are federal. The EPA's construction and demolition conversion factors list carpet at 147 pounds per cubic yard and carpet padding at 62, and county waste tables report the same figures. Carpet is a soft, flat material, so these loose factors hold up against a physical check, unlike the ones for dense rubble.
- Face weight and carpet construction: The Carpet and Rug Institute, the carpet industry's standards and testing organization.
- Loose debris density: U.S. EPA, Volume-to-Weight Conversion Factors (April 2016), carpet 147 lb/yd³, padding 62 lb/yd³.

Common questions
How much does carpet weigh per square foot?
About 0.5 to 0.8 pounds per square foot for typical synthetic carpet, or roughly 5 to 7 pounds per square yard. Denser nylon and wool run heavier, up to about 2.2 pounds per square foot. Add padding and a room gets close to a pound per square foot.
How much does a roll of carpet weigh?
A 12 by 12 room's worth is about 90 to 130 pounds. That's 16 square yards of synthetic carpet rolled up; the pad from the same room adds another 30 to 65 pounds. Wool or thick commercial carpet from that space weighs half again as much.
Does carpet padding add much weight?
Yes, about a third to half of the carpet's weight. Rebond padding runs roughly 0.2 to 0.45 pounds per square foot. It's light, but it's bulky and springy, so it fills dumpster space fast even though it barely moves the scale.
Will carpet overweight a dumpster?
Almost never when it's dry. Carpet is light for its bulk and fills a container's volume before it hits the weight cap. Water-damaged or flooded carpet is the exception, holding two to three times its dry weight and turning a light load heavy.
What size dumpster do I need for carpet?
A whole-house re-carpet usually fits a 10 or 15 yard dumpster. Bulk sets the size, not weight. For one or two rooms, a dumpster is often overkill; cut the carpet into strips, roll it tight, and a hauler or curbside bulk pickup can take it without a container.
Disclaimer: These weights are estimates for dry residential carpet and padding. Actual weight varies with fiber, backing, pile density, and moisture. Wet or flooded carpet weighs far more and can carry mold. For a large tear-out, confirm dumpster sizing and any carpet recycling options with your hauler.
