For a really low-tech approach: use an S3 client that can calculate the size for you. I'm not sure how fast or accurate it is in relation to other methods, but it seems to give back the size I had expected it to be. Since there are so many answers, I figured I'd pitch in with my own. Copy, paste, and enter in the access key, secret key, region endpoint, and bucket name you want to query. Testing against one of my buckets, it gave me a count of and a size of I know that is This tool gives statstics about objects in a bucket with search on metadata.
Also Hanzo S3 Tools does this. Once installed, you can do:. By Cloudberry program is also possible to list the size of the bucket, amount of folders and total files, clicking "properties" right on top of the bucket. If you don't want to use the command-line, on Windows and OSX, there's a general purpose remote file management app called Cyberduck.
I wrote a Bash script, s3-du. It does do subdirectory size, as Amazon returns the directory name and the size of all of it's contents. I think this link will work for anyone already logged into AWS Console:. Sign up to join this community. The best answers are voted up and rise to the top.

I wrote a tool for analysing bucket size: github. I am astonished that Amazon charge for the space, but don't provide the total size taken up by an S3 bucket simply through the S3 panel.
For me most of the answers below took quite a long time to retrieve the bucket size, however this python script was way faster than most of the answers - slsmk. Add a comment. Active Oldest Votes.

For large buckets large files , this is excruciatingly slow. Data retrieval cost depends on storage tier—it is higher for the infrequent access storage classes, compensating for their lower data storage price.
Amazon uses a tiered data transfer pricing structure, with a lower cost the more data you transfer outside the S3 service each month. If you need faster data transfer, you can pay extra for accelerated transfers. For cross region replication CRR , you also have to pay for inter-region data transfer from S3 to each destination region. You also pay for S3 replication metrics. When moving your workloads to AWS, you need to understand their performance and data access requirements.
For example, the requirements for a backup and archive application will be completely different from the requirements of a streaming service or an E-commerce application. In order to manage your storage costs, you need to know when and how your data is retrieved, accessed, archived or deleted by a user.
Amazon S3 offers tools that let you organize data organization at the object or bucket level. This is important for optimizing costs. You can use object tags, name prefixes, and S3 buckets to organize your data:. Amazon S3 Storage Class Analysis allows you to configure filters that categorize objects for analysis using object tags and key name prefixes. Amazon CloudWatch metrics can be customized to display information using specific tag filters. Amazon S3 provides several storage classes suitable for various use cases, with each class supporting a different level of data access with corresponding pricing.
Choosing the right storage class for each use case is essential to planning your S3 cost optimization strategy. There are three key elements to selecting the best storage class for your data in S3: monitoring, analysis, and optimization. It is important to monitor your S3 usage so you can reduce storage costs and adjust for growth. You can use AWS Budgets to set a budget and get alerts when your usage or costs exceed, or are expected to exceed, the specified budget.
You don't need the grep part if you ls a single bucket. AWS Cloudwatch now has a metric for bucket size and number of objects that is updated daily. About time! SamMartin what does StorageType need to be? Also this answer takes a very long time to compute for buckets bigger than GB — Vivek Katial.

Note also that this will capture hanging incomplete uploads, with the ls -based solutions don't. FYI - I tried this and the aws cli version in cudds answer.
They both work fine, but s3cmd was significantly slower in the cases I tried as of release 1. DougW: Thanks, useful info. Seems the s3cmd maintainer is looking into adding support for AWS4: github.

I had to use double quotes around the query string in windows command line. Works like a champ though. Beware: if the bucket is empty the command would fail with the following error: In function sum , invalid type for value: None, expected one of: ['array-number'], received: "null" Otherwise the query works great!
AWS documentation indicates that if you need to get the size of a bucket use that command which works well in most cases. However, it's not suitable for automation because sometimes you might have a scenario where some of the certain buckets have thousands or millions of records. The command will have to iterate through the complete list before it can render the required bucket size information. It's not suitable for automation. On linux box that have python with pip installer , grep and awk , install AWS CLI command line tools for EC2, S3 and many other services sudo pip install awscli then create a.

S3 Standard Storage is suitable for the general-purpose storage of frequently accessed data. Because you only pay for what you use, S3 Standard Storage is suitable for most cases including data-intensive, user-generated content, such as photos and videos. S3 Infrequent Access Storage is great for storing data you don't need frequent access to, but may need to access in a hurry—i.
The Amazon S3 cost for Infrequent Access Storage is less than Standard Storage, but you pay more each time you access or retrieve data. Usually, when data is assigned to a Region, it's distributed between at least three Availability Zones in order to maximize durability. For data that isn't accessed often, but still needs quick retrieval times and can tolerate lower availability rates, use One Zone Infrequent Access Storage. Similar to S3 One-Zone Infrequent Access Storage, S3 Reduced Redundancy was originally introduced to offer a lower-priced option for storage that was replicated fewer times than standard S3.
S3 Glacier storage is for long-term data archiving. Typically this storage class is used when record retention is required for compliance purposes. Retrieval requests can take up to five hours to complete, which is why this is an inappropriate storage class for data you want to access quickly. For even longer-term data archiving, S3 Glacier Deep Archive offers cost-saving opportunities for data that is retrieved one or two times per year. An important consideration for organizations with large volumes of data to archive is that it may take up to 12 hours to resolve data retrieval requests.
Amazon also provides an Intelligent Tiering service to automatically transfer data between the Standard S3 and Standard Infrequent tiers depending on access patterns. Confused about when to use each class of S3? Use this decision-tree to clarify when each Amazon cloud storage class is most appropriate:.
It's important to note that minimum capacity charges apply to data stored in the two Infrequent Access classes current minimum is KB , and minimum storage duration charges apply to data stored in the two Infrequent Access classes current minimum is 30 days , S3 Glacier class current minimum is 90 days , and S3 Glacier Deep Archive class current minimum is days.
