Adding a bit to @alexdo’s answer, when you create a Droplet via the API, you will supply a “size slug.” Size slugs are human-readable strings used to specify the type of Droplet in certain API requests. They are comprised of the identifier for the Droplet’s class, the vCPU count, and the amount of RAM. For example, the $5 per month Standard Droplet comes with 1 vCPU and 1 GB of RAM. So its size slug is: s-1vcpu-1gb

Size slugs for General Purpose Droplets are prefixed with g- So the 8 GB RAM, 2 CPU General Purpose Droplet would be g-2vcpu-8gb

In order to get a full list of all the available Droplet sizes and their corresponding size slugs, you can:

• See this page for online reference: https://slugs.do-api.dev/
• Use the /v2/sizes API endpoint if you need to access them programmatically
• List them on the command line with: doctl compute sizes list
