In most devices, you just need to head to 'Settings' and your storage capacity will be listed there.

In Apple Devices, it's at Settings > General > About or Settings > General > Device (depending on what make and model you have).

Otherwise, it will either be called Storage or Capacity. Some devices will be different – in which case a quick Google search should help.

If you can't find it or your device doesn't turn on, just choose 'Not sure' and we'll work it out for you later.

Storage enables a device to retain data, either temporarily or permanently. Measured in megabytes (mb), gigabytes (gb) and terabytes (tb), storage is a fundamental part of most digital devices. It allows users to preserve all kinds of information such as videos, documents, pictures and raw data.
