If you want the gigabyte size of partitions why not use df? This shows filesystem, size, used and available together with where it is mounted. If you want it to miss off the less useful ones and still keep the header use it with a pipe to grep -v "^none":

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 29G 3.9G 23G 15% /
none 1.9G 280K 1.9G 1% /dev
none 2.0G 2.0M 2.0G 1% /dev/shm
none 2.0G 116K 2.0G 1% /var/run
none 2.0G 0 2.0G 0% /var/lock
none 2.0G 0 2.0G 0% /lib/init/rw
/dev/sda6 170G 61G 100G 38% /home

$ df -h | grep -v "^none"
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 29G 3.9G 23G 15% /
/dev/sda6 170G 61G 100G 38% /home
