What Size is iPhone 7 Plus? Screen Dimensions & Specs Explained

The iPhone 7 Plus represents a major step in Apple’s smartphone design, combining a larger display, dual-camera system, and refined aluminum chassis. Understanding what size is iPhone 7 Plus helps users compare it to previous models and choose the right case, screen protectors, and accessories.

Below is a detailed summary of the key physical and technical specifications that define the size and form of the device.

Height and Width Dimensions

The height of the iPhone 7 Plus measures 158.2 mm, which is about 6.23 inches, making it noticeably taller than smaller iPhones. Its width is 77.9 mm, or 3.07 inches, giving the device a horizontal layout that fits comfortably in two hands with a firm grip.

When held vertically, the taller screen shows more content at once, especially in apps and mobile browsers. The width across the back aligns closely with many full-size cases and tempered glass protectors designed specifically for this model.

These measurements affect everyday usability, from pocket fit to one-handed reach, and they guide accessory makers in designing precise mounts, holders, and sleeves that work seamlessly with the device.

Depth and Chassis Thickness

With a depth of 7.3 mm, the iPhone 7 Plus is slightly thicker than its predecessor, allowing space for larger camera lenses and additional internal components without making the phone awkwardly bulky.

The relatively slim profile contributes to a balanced feel in the hand, reducing pressure on the palm during extended use. This thickness also enables better speaker placement and improved water resistance sealing compared to thinner designs.

Because the back is relatively flat, users often find that basic soft cases or slim hard cases maintain a comfortable profile while still protecting the camera lenses and corners.

Weight and Balance

At 188 grams, the iPhone 7 Plus is heavier than many compact phones, largely due to the dual-camera system and larger battery required to power the bigger display.

Despite the added weight, the distribution of components across the chassis helps the phone feel stable when resting on a flat surface and reduces top-heaviness during video calls.

Some users may prefer a case with integrated hand straps or a grip ring to improve comfort during long one-handed sessions, especially in comparison with lighter, smaller iPhones.

Display Size and Resolution

The 5.5-inch display is a central element of the iPhone 7 Plus size identity, providing more screen real estate for reading, gaming, and multitasking compared to smaller models.

With a resolution of 1920 by 1080 pixels, the pixels per inch remain high enough for sharp text and detailed images, ensuring that the larger screen does not come at the cost of clarity.

Larger displays also influence battery consumption, which is why Apple paired this form factor with an increased battery capacity to preserve runtime through the day.
