How Much Do Aluminum Cans Weigh? Most empty drink cans land around 13 grams, with size, lid style, and print adding small swings.
If you’ve ever hauled a sack of empties to the recycler, you’ve felt it when you ask how much do aluminum cans weigh: the bag turns into a workout.
That mismatch comes from two things. First, a single can is light. Second, you usually have a lot of them.
You’ll get real numbers for common can sizes, a fast home weighing method, and simple pound and kilo math.
Quick weight ranges for common aluminum cans
There isn’t one universal weight. Makers tweak metal gauge, end design, and neck shape. The ranges below work for recycling math and quick estimates.
| Can type | Capacity | Typical empty weight |
|---|---|---|
| Standard drink can (US “12 oz”) | 355 mL | 12.5–14.5 g |
| Standard drink can (EU “330 mL”) | 330 mL | 13–20 g |
| Slim can | 250 mL | 9–11 g |
| Sleek can | 330 mL | 12–16 g |
| Tall can (“16 oz”) | 473 mL | 15–18 g |
| “19.2 oz” can | 568 mL | 18–22 g |
| Mini can | 150–200 mL | 7–10 g |
| Heavier specialty can (thicker wall or reseal end) | Varies | +2–6 g vs similar size |
Want a single “anchor” number? The Aluminum Association reports an average aluminum can metallic weight of 12.99 grams. That’s a midpoint when you don’t know brand. The figure appears in their KPI report on beverage can recycling: average aluminum can metallic weight.
How much do aluminum cans weigh by size and style
When people ask, “how much do aluminum cans weigh?” they usually mean a clean, empty drink can. That’s the base can with its tabbed end, any paint or ink, and the thin inner liner. It does not mean a can full of soda, beer, or sparkling water.
Standard 12 oz cans
Most North American soda and beer cans sit in the 12.5–14.5 gram band. A Ball 12 oz can listing sold to beverage producers shows 13.61 grams (0.48 oz), which lands right in the middle of the range many people see on a kitchen scale.
Over time, can makers have trimmed weight through better forming and tighter metal use. Ball has stated that a 12-ounce beer can can weigh 0.47 ounces in modern form in its note on the 75th anniversary of the beer can.
330 mL cans
The 330 mL format shows a wider spread. Some are built like standard cans, some are built like sleek cans, and some target strength for long transport. A practical range is 13 to 20 grams for a plain, empty 330 mL aluminum can.
Slim and sleek cans
“Slim” and “sleek” are shape families, not just a size. Slim cans are tall and narrow. Sleek cans are also narrower than a classic 12 oz can, with a smoother shoulder. Shape changes the metal needed for the same volume, so these formats can weigh less than you’d guess.
- Slim 250 mL often lands near 9–11 grams.
- Sleek 330 mL often lands near 12–16 grams.
Tall cans and “19.2 oz” cans
On 16 oz and 19.2 oz cans, weight climbs mainly due to surface area.
For quick math, treat a 16 oz can as 15–18 grams and a 19.2 oz can as 18–22 grams. The table above keeps you in the right lane.
What changes an aluminum can’s weight
Two cans can hold the same amount of liquid and still weigh differently. Here are the usual reasons you’ll see a swing of a gram or three.
End and tab design
The lid (the “end”) uses a different alloy and can be thicker than the sidewall. A full-open end, a stay-on tab, or a specialty opening shape can add a bit of metal. Crushing changes the feel, not the mass.
Neck and shoulder shape
Cans get “necked in” near the top so the end can be smaller than the body. The exact neck profile varies by plant and line. Tiny shape changes mean tiny weight changes, yet those add up across truckloads.
Decoration and coatings
Paint, ink, and varnish add a little. So does the inner liner. You won’t feel it with one can. On a scale, it can show up as a fraction of a gram. If you’re trying to match a scrap-yard payout, that fraction can matter when you’re weighing hundreds of cans.
Strength targets
Some cans need to handle higher pressure, warmer fill, or longer travel without dents. Those cans can use thicker stock. If a can feels stiff when you squeeze the sidewall, it may be on the heavier end for its size.
Simple ways to weigh a can at home
You don’t need lab gear. A small kitchen scale can get you close enough for real life.
Method 1: Single can check
- Rinse the can and let it drain for a minute. A teaspoon of water skews the result.
- Set your scale to grams.
- Place the empty can upright, uncrushed.
- Write down the number, then repeat with two more cans from the same brand.
If the three numbers match within 0.5 grams, you’ve got a solid “house average” for that brand.
Method 2: Batch average for better accuracy
Some scales round hard at low weights. Batch weighing fixes that.
- Count 25 empty cans of the same type.
- Weigh them together.
- Divide the total grams by 25.
This also helps if you’re mixing brands. Do one batch per can type, then blend the averages based on how many you have of each.
Quick math for recycling, shipping, and scrap
Once you have a per-can weight, you can do useful math fast. If you don’t have a scale, the 12.99-gram average is a fair stand-in for standard drink cans.
How many cans make a pound
A pound is 453.6 grams. Divide that by your can weight.
Using 12.99 grams per can, you get 453.6 ÷ 12.99 = 34.9 cans. In plain terms, call it 35 standard cans per pound.
How many cans make a kilogram
A kilogram is 1,000 grams. With 12.99 grams per can, that’s 1,000 ÷ 12.99 = 77 cans per kilogram.
What about a full can
A full can is mostly liquid. Water is 1 gram per milliliter, so a full 355 mL can holds around 355 grams of liquid, plus the can itself. Soda and beer sit close to water in density, so the ballpark stays similar.
If you’re lifting a case, liquid weight is the big deal. If you’re cashing in empties, the aluminum weight is the deal.
How Much Do Aluminum Cans Weigh? Fast answers by common goal
People ask the same question with different goals. Here’s the quick mapping from goal to the number you should use.
If you’re estimating recycling weight
Use a per-can average from your own stash if you can. If not, use 12.99 grams per can for standard drink cans.
If you’re planning shipping or packing
Use the can-plus-liquid weight. For a 12 oz can, count the liquid as 355 grams, then add 13 grams for the can. Multiply by the number of cans, then add packaging.
If you’re comparing packaging formats
A can is light partly because its walls are thin. Industry groups often cite an average can weight near 13 grams after decades of weight cuts, which shows up fast in freight math once you multiply by pallets and truckloads.
| Quick question | Use this weight | One-line math |
|---|---|---|
| How many 12 oz cans per pound? | 12.99 g each | 453.6 ÷ 12.99 = 35 cans |
| How many 12 oz cans per kilogram? | 12.99 g each | 1,000 ÷ 12.99 = 77 cans |
| What does a bag of 200 cans weigh? | 12.99 g each | 200 × 12.99 = 2,598 g (2.6 kg) |
| What does a case of 24 full cans weigh? | Liquid + can | 24 × (355 + 13) = 8.8 kg |
| What if cans are slim 250 mL? | 10 g each | 453.6 ÷ 10 = 45 cans |
| What if cans are 16 oz? | 16 g each | 453.6 ÷ 16 = 28 cans |
| Is crushing changing weight? | No change | Shape changes, mass stays |
Common mistakes that skew the number
Most “my bag weighs more than it should” moments come from simple stuff you can fix in a minute.
Water trapped in the bottom
Rinsed cans can hold water in the dome. Tip them upside down and give them a shake. A few grams of water is easy to miss and big enough to throw off a small batch.
Mixing steel cans into the pile
Some drink cans are steel in some regions, and food cans are often steel. A magnet tells the truth. Aluminum won’t stick. Steel will. If you mix them, your average weight jumps and your scrap value can drop.
Counting crushed cans as “smaller” cans
A flat can feels lighter because it’s thinner and takes less space. The scale doesn’t care. Crushing helps with storage and transport, not with weight.
A quick checklist you can save
- For a standard drink can, start with 13 g if you don’t know the brand.
- Weigh 25 cans at once if your scale jumps around.
- For pounds, think “35 cans per pound” as a fast rule of thumb.
- For kilos, think “77 cans per kilogram” as a fast rule of thumb.
- Drain rinse water before weighing.
- Use a magnet to keep steel out of the pile.
If you came here asking how much do aluminum cans weigh? you now have a range that fits most real piles, plus a clean way to measure your own stash and do the math in seconds.
