df shows file system usage. Unless you know the disk is partitioned with a single partition using all available disk space, it's safer to use something like parted, fdisk, or smartctl:

Code: 
sean-laptop sean # parted /dev/sda print
Model: ATA SAMSUNG MZ7TD256 (scsi)
Disk /dev/sda: 256GB
<output truncated>

sean-laptop sean # fdisk -l /dev/sda
Disk /dev/sda: 238.5 GiB, 256060514304 bytes, 500118192 sectors
<output truncated>

sean-laptop sean # smartctl -i /dev/sda
smartctl 6.4 2015-06-04 r4109 [x86_64-linux-4.5.0-gentoo] (local build)

The kernel messages will generally include the size of the disk during device detection as well:

Code: 
sean@sean-laptop ~ $ grep sda /var/log/dmesg
