Full Size of Terraform for VPS on Digital Ocean?

I have an Ubuntu 20.04 Droplet on Digital Ocean. I’m looking at Terraform. What’s the final Size of Terraform? Red Baron. I don’t have a lot of space. On my Droplet. 50GB and I’m using 50%. I want to keep the size very low. So how big is it? Installed? I’m searching Red Baron on GitHub. Looks good. Can I choose which modules to install? Bring the size down. Please reply. Thanks
