Instagram has confirmed that it will increase image resolution from 640 by 640 pixels to 1080 by 1080 pixels. Instagram’s images have measured 640 pixels since launch.
When the photo-sharing service first arrived, 640 pixels was appropriate based on screen and camera capabilities. Now that smartphones and tablets boast screen resolutions up to quad HD and cameras capturing 21-megapixels, the 640-pixel resolution was deemed inadequate.
Instagram said the Android and iOS apps are being updated to upload 1080p images slowly, but would not say when all users will be able to see the higher-resolution imagery.
