If you want to take a picture with your iPhone and upload it to Instagram, Facebook, or any other social media site, make sure the photo size is correct. Here’s how to check:

  1. Open the Photos app on your iPhone.
  2. Tap on an image you want to share.
  3. On the bottom right of the screen, tap on the three lines in a triangle.
  4. Under “Size,” tap on “Original.” If you want to post the image online, make sure “Scale To Fill Screen” is turned off and “Width” is set at its default value of 640 pixels. ..
