Phone Storage Calculator
See how much usable storage your phone really has after the operating system and apps.
About the Phone Storage Calculator
Built for Pakistani users, the Phone Storage Calculator turns a fiddly manual calculation into a one-glance result you can trust for planning and everyday decisions.
Storage decisions — how much phone or laptop storage you need, or how long a recording fits — come down to data-size math. This Phone Storage Calculator computes one of those figures so you buy the right capacity and never run out at the wrong moment.
The calculation converts between storage sizes and content requirements — how many photos, videos or apps fit in a given capacity — using realistic file sizes for each content type.
Modern phones in Pakistan sell in 128 GB, 256 GB and 512 GB variants, and the difference matters: a 128 GB phone can fill up fast with videos and games. This calculator shows you the real capacity you need.
Remember that usable storage is always less than the advertised figure — the operating system and preinstalled apps take a share. Account for that when choosing a capacity.
For the most accurate outcome from the Phone Storage Calculator, keep the editable rates and defaults up to date with current figures before reading the result.

Frequently Asked Questions
Why is my phone's storage less than advertised?

How much storage do I need on a phone?
A typical user fills 64–128 GB with apps, photos and videos in 1–2 years. Heavy video shooters should choose 256 GB or more. Account for the OS and system apps taking 10–20 GB.
