About How Much Storage

How Much Storage is a free digital storage calculator. It helps you estimate the capacity you need for a phone, laptop, SSD, SD card, or cloud plan.

You shouldn't have to understand megabytes, bitrates, codecs, or storage overhead just to decide between 128 GB, 256 GB, 512 GB, and 1 TB. You answer a few normal questions about how you use your device, and the calculator handles the math behind the scenes.

For anyone who wants to inspect the exact file-size ranges, headroom rules, and external sources we use, everything is documented openly on our calculation methodology page.
