The iPhone SE will have the same screen resolution as the iPhone 5s: 1,136 by 640 pixels, which comes out to 326 pixels per inch (ppi).
The 326 ppi is same density as the iPhone 6s, even though that phone has a larger 4.7-inch display with resolution of 1,334 by 750 pixels. The iPhone 6s Plus phablet has the biggest screen of all: a 5.5-inch, 1920 by 1,080 pixel display, with a density of 401 ppi.

One major feature missing from the iPhone SE, that’s found in the iPhone 6s and 6s Plus is 3-D Touch, which lets a phone distinguish between a light tap and a firm press, letting users control apps differently depending on how hard they push on their phone’s touchscreen.
Like the iPhone 6s and iPhone 6s Plus, the iPhone SE will be sold in space gray, silver, gold and rose gold.

Smaller size, smaller price tag: The iPhone SE will be less expensive than the 6S and 6S Plus, starting at $399 unlocked with 16GB of storage or $499 with 64GB of storage. That’s $50 less than the iPhone 5s was selling for until Monday, and $200 less than an unlocked 16GB iPhone 6s. (The iPhone 6s Plus starts at $749 unlocked.)
