DB LabsQuick Answer
iOS does not display individual photo file sizes in the Photos app. To find your biggest photos, the easiest method is to use Settings > General > iPhone Storage > Photos > Review Personal Videos, which sorts videos by size. For photos specifically, sort by date in Albums > Media Types > Videos (videos are almost always the biggest items) or use the Files app to share-sheet a photo and view its size. The Mac Photos app shows file sizes in the inspector view if you sync via iCloud Photos.
The Built-in iPhone Method
Apple does not make finding the biggest photos easy on iPhone, but iOS has hidden tools that help.
Settings > iPhone Storage > Photos
Open Settings > General > iPhone Storage. Wait for the list to load and tap Photos. Scroll to see Review Personal Videos. This is a built-in feature that shows your largest videos sorted by file size, with Delete buttons for each. It is the closest thing iOS offers to a size-sorted view.
Albums > Media Types > Videos
Open Photos > Albums > Videos. This shows all your videos sorted by date. Videos are almost always the largest items in your library, so even sorted by date, the recent 4K clips are usually the biggest space hogs.
Use the Mac Photos App
If you have a Mac and use iCloud Photos, the Mac Photos app shows file sizes in the inspector. Open Photos on Mac, click View, then Show Inspector. Click any photo and the inspector shows file size, dimensions, camera info, and more. You can sort by size in some smart album views.
Use the Files App Trick
The Files app can show file sizes. Save a photo to the Files app temporarily: open Photos, tap the share button, scroll down to Save to Files, and pick a folder. Open Files and view the photo: long press to see size info.
Find the Biggest Single File Type
Most large photos fall into one of these categories:
- Screen recordings: Often 100 MB to several GB each. Albums > Screen Recordings.
- 4K videos: Around 400 MB per minute. Long ones can be huge.
- ProRAW photos: 25-30 MB each. Visible in the metadata but not specifically tagged.
- Live Photos: 2-3x the size of a regular photo because they include video.
Use a Third-Party Storage App
Some apps in the App Store can scan your library and report size details. Cleaner Pro, Gemini Photos, and similar apps offer size-based filtering. Read reviews carefully because some claim more than they deliver.
The Easier Approach
Instead of hunting for the biggest individual photos, focus on bulk cleanup. Use Swype Photo Cleaner to swipe through your library. You will quickly identify and delete blurry shots, duplicates, and old screenshots without needing to know exact file sizes. Most users free 5-15 GB this way without ever sorting by size.
The Bottom Line
iOS does not give you a sorted-by-size view in the Photos app, but the built-in Review Personal Videos feature in Settings handles the most important case: your biggest videos. For everything else, focus on deleting what you do not need rather than finding the biggest individual files.
