Apple has four different iPad lines: the iPad, the iPad Mini, the iPad Air, and the iPad Pro. They range in screen size from 7.9 inches to 12.9 inches and have varying resolutions, so determining the actual screen resolution of your iPad will depend on the model.
What's the RIGHT iPad Screen Size for You? When Size Matters
All iPads have multi-touch IPS displays with a 4:3 aspect ratio. While the 16:9 aspect ratio is considered best for watching high-definition video, the 4:3 aspect ratio is considered better for browsing the web and using apps. Later models of the iPad also include an anti-reflective coating for easier viewing in sunlight. The latest iPad Pro models have a "True Tone" display, which has a wider color gamut than what's available on other iPads.
The iPad's native resolution remained until the iPad 3 came out in 2012 with the Retina display.
The 1024×768 resolution was also used with the original iPad Mini. The iPad 2 and iPad Mini were the two best-selling iPad models, making this resolution one of the most popular configurations to this day. All modern iPads have moved to the Retina Display with varying resolutions based on their screen size.
