To check iPhone storage, open Settings , go to General, then tap iPhone Storage; you’ll see how much space is used, what’s free, and which apps are taking up the most room.

Quick Scoop

  • Open Settings on your iPhone.
  • Tap General.
  • Tap iPhone Storage.
  • At the top, you’ll see used vs available storage, plus a colored bar showing what types of data (apps, photos, system, etc.) are using space.
  • Scroll down to see a list of apps ordered by how much storage they use; tap any app to see details and options to remove data or delete it.

See Total Capacity (GB)

If you want to know your iPhone’s total built‑in storage (like 64 GB, 128 GB, etc.), use the About screen.

  • Go to Settings → General → About.
  • Look for Capacity (total storage) and Available (free space) in GB.

Check iCloud Storage

You can also see how much iCloud storage you’re using and what’s filling it.

  • Open Settings and tap your name at the top.
  • Tap iCloud to see a storage bar and breakdown (photos, backups, etc.).

Extra Tip: From a Computer

If your iPhone is connected to a Mac or PC, you can view storage from there too.

  • Connect your iPhone, then open Finder (macOS) or iTunes / Apple Devices app.
  • Select your iPhone to see a bar showing storage by content type (apps, photos, system, etc.).

TL;DR: Settings → General → iPhone Storage shows what’s using space and how much you have left; Settings → General → About shows total capacity; Settings → your name → iCloud shows iCloud storage.
