How to find out the size of my computer hard disk?

Question

How can I see the total disk size of my hard disk?

I have used the following command:

# fdisk -l | grep Disk
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes, ********** sectors
Disk identifier: 0x0003dd50
Disk /dev/mapper/fedora_new--host--5-swap: 6274 MB, ********** bytes,
12255232 sectors
Disk /dev/mapper/fedora_new--host--5-root: 53.7 GB, ********** bytes,
104857600 sectors
Disk /dev/mapper/fedora_new--host--5-home: 939.7 GB, **********
bytes, ********** sectors
#

Should I conclude that the size of my hard disk is 1 TB?
