To get the size of an S3 Bucket, open the AWS S3 console and click on the bucket's name. Then navigate to the Metrics tab. In the `Bucket Metrics` section you can see the `Total bucket size` graph, which displays the size of objects in the bucket.

How to Get the Size of an AWS S3 Bucket


## Get the Size on an S3 Bucket

**In order to get the size of an S3 Bucket, you have to:**

1. Open the AWS S3 console and click on your bucket
2. Click on the `Metrics` Tab
3. In the `Bucket Metrics` section, the `Total bucket size` graph shows the
   total size of the objects in the bucket

You can hover over the line in the graph to look at the size movements of your
bucket. These metrics are also available in CloudWatch.

The next graph on the page shows the total number of objects in the S3 bucket.

<Alert>
  Note that this metric is updated daily, so if you have performed PUT / DELETE
  actions on the bucket in the past 24 hours, it might not be up to date. Hover
  over the graph line to see the last time it got updated.

**To get the size of an S3 Bucket using the AWS CLI, run the `s3 ls` command,
passing in the `recursive`, `human-readable` and `summarize` parameters.**

<Alert>
  S3 List operations cost about <code>$0.005</code> per <code>1,000</code>{' '}
  requests in the <code>us-east-1</code> region. For example, if your bucket
  contains <code>1,000,000</code> objects, the List operation would cost you{' '}
  <code>1,000 * $0.005 = $5</code>
</Alert>

```bash:shell
aws s3 ls s3://YOUR_BUCKET --recursive --human-readable --summarize
```

The command's output shows:

- the date the objects were created
- their individual file sizes
- their path
- the total number of objects in the s3 bucket
- the total size of the objects in the bucket

The parameters we've passed to the
[s3 ls](https://awscli.amazonaws.com/v2/documentation/api/latest/reference/s3/ls.html)
command are:

| Name           | Description                                               |
| -------------- | --------------------------------------------------------- |
| recursive      | performs the command on all files under the set prefix    |
| human-readable | displays the file sizes in human readable format          |
| summarize      | displays the total number of objects and their total size |

**To get the size of the objects in a specific folder of an S3 bucket, call the
`s3 ls` command with the complete S3 URI pointing to the folder.**

```bash:shell
aws s3 ls s3://YOUR_BUCKET/YOUR_FOLDER/ --recursive --human-readable --summarize
```

- many others

The metrics get collected daily and are retained for a period of 14 days.
