Method 3 of 5:

Using a Computer

1
Connect your iOS device to your computer. Use the USB cable that came with the device.
2
Open your iOS device on your computer. The process varies a little depending on whether you're using Windows or Mac:
- Windows - Double-click "My Computer", then double-click the iOS device in the "Devices and Drives" section.
- Mac - Double-click the iOS device icon that appears on your desktop.
3
Double-click the "DCIM" folder.
4
Find the image that you want to check.
5
Open the details for the image file. Once you've found the image, you can open a new window displaying information about it.
- Windows - Right-click on the image, then click Properties.
- Mac - Select the image, hold down Command, and tap I.
6
Review the photo's size. You should be able to see the easy-to-read size (e.g. 1.67 MB) as well as the actual exact size (e.g. 1,671,780 bytes).
- The photo's size should be next to a heading that says "Size" or "File Size."

Method 4 of 5:

Using the Mail App

1
Open the Photos app. While you can't actually check the size of the photo in the Photos app, you can add it to an email message to check the approximate size. You won't actually need to send an email to do so.
2
Tap Albums. This is in the bottom right corner of the screen.
3
Tap Camera Roll. You can also tap a different album on this screen if you'd like to narrow your results.
4
Select a photo.
5
Tap the "Share" button. It resembles a box with an arrow coming out of the top in the bottom left corner of your screen.
6
Tap Mail. This will open a new mail message with the image attached.
7
Tap the "To" field.
8
Type in your own email address.
9
Tap Send. You will be prompted to select the size of your photo.
- If you didn't add a subject to your email, you'll have to confirm that you want to send the email without a subject before continuing.
10
Review the "Actual Size" value. This should be at the bottom of the page--the Actual Size value will tell you the approximate size of your selected photo.
- If you selected multiple photos, you'll only see their total size (not a photo-by-photo breakdown).

Method 5 of 5:

Using a Jailbroken iOS Device

This method only works for jailbroken devices, and allows you to see photo data directly from the Photos app. Jailbreaking can be a tricky process, and will void your warranty.

1
Open Cydia on your jailbroken device. You can use Cydia to install a special tweak to your Photos app that will allow you to view detailed information for your photos.
2
Tap Search. This is in the bottom right corner of your screen.
3
Type "Photo Info" into the search field.
4
Tap Photo Info.
5
Tap Install. This is in the top right corner of your screen.
6
Tap Confirm. Cydia will download and install the tweak.
7
Tap Restart SpringBoard. Doing so will restart your system to finalize the tweak's installation.
8
Select a photo from your Photos app.
9
Tap ⓘ. This should be at the bottom of the screen.
10
Review the "File Size" entry. This value will appear at the bottom of your screen. Now you know the file size of your selected photos.
