The default install of Ubuntu is in the neighborhood of 15GB. When comparing full on general purpose desktop environment distros, 4.2GB is pretty reasonable. Obviously if you're using a hand-tuned Arch or something you can get a much smaller base install size for your needs.

Ubuntu 22.04 desktop, the normal installation with LibreOffice and other extras, is about 7.1GB for me in a VM.

You can also start with minimal(-ish) Ubuntu Server and generally add the packages you want.
