How to know the size of a package

Question

Lets say I want to install the gcc package using sudo apt-get install gcc but before I want to know the size of it, is there a command for that ?

Answer 1

If you run

sudo apt install gcc

you will get a prompt showing the packages to be installed and required space, asking if you want to continue.

To see the download size of a specific package you can run e.g.

apt show gcc
