Prerequisites

To follow along with this guide, please make sure to have:

  • created a service account and downloaded the private key (JSON file) for authentication (please check out my detailed guide)

  • installed the Python client library for Google Cloud Storage:

    pip install --upgrade google-cloud-storage

Getting the size of file in Google Cloud Storage

To get the size of a file called cat.png in Google Cloud Storage using Python, get the file using the get_blob(~) method, and then check the blob's size property:

from google.cloud import storage

# Authenticate ourselves using the private key of our service account
path_to_private_key = './gcs-project-354207-099ef6796af6.json'
client = storage.Client.from_service_account_json(json_credentials_path=path_to_private_key)

bucket = storage.Bucket(client, 'example-bucket-skytowner')
blob = bucket.get_blob('cat.png')
print(f'{blob.size} bytes or {blob.size/1000} KB')
160546 bytes or 160.546 KB
WARNING

Here, you must use the method bucket.get_blob(~) instead of bucket.blob(~) since get_blob(~) sends a request to GCS to fetch the meta-information of the file (e.g. size), while blob(~) does not.
