title: AWS - how to find the total size of a lambda function that uses layers
body: <p>How can you find the total size of a lambda function that uses your own layers including shared layers?  There doesn't appear to a single place where you can find the total size of your lambda function that uses all the layers.</p>
  
  <p>Lambda deployment package with all layers unzipped should not be more than 250 MB.</p>
  
  <p>I want to avoid having to download each lambda layer and I can't find if you use a shared aws layer like numpy that aws provides on how to find the size.  Would be nice if in your lambda function it had a total size of all packages used in MB (idea....AWS...please)!</p>
