iPhone 8 Plus dimensions in inches, at a glance
The iPhone 8 Plus measures 5.5 inches tall, 2.64 inches wide, and 0.29 inch thick (139.1 mm x 67.1 mm x 7.3 mm). These verified specs cover screen height, body width, and device depth to help you judge fit, clearance, and case compatibility. Below we break down each dimension and translate it into real-world use cases like pocketability, grip comfort, and case fit.
Screen and display dimensions
Screen height and width in inches and millimeters
The iPhone 8 Plus has a 5.5-inch diagonal display with an approximate 106.7 mm (10.67 cm) vertical viewable area and 67.1 mm (6.71 cm) shorter side. Keep in mind that bezels and the sensor housing reduce the usable space for content, and the true viewable area is slightly smaller than the quoted screen size.
Body and chassis dimensions
Height, width, and depth
The unibody chassis dimensions are 5.50 inches (139.7 mm) in height, 2.64 inches (67.1 mm) in width, and 0.29 inch (7.3 mm) in depth. These figures represent the maximum extent of the phone and are the key numbers to compare against cases, pockets, and bag compartments.
Weight and practical handling notes
The iPhone 8 Plus typically weighs around 202 grams (7.1 ounces). Depth and weight together affect pocket comfort and one-hand reach; the relatively shallow depth at 0.29 inch helps the phone sit flush in pockets, while the top-heavy camera bump can influence perceived balance when gripping the device.
Case and accessory fit considerations
Clearance around the frame and camera bump
Because the camera module sits proud of the rear panel, many cases must accommodate roughly 2.5 mm to 3 mm of bump height. When sizing cases, use the body measurements above plus the bump depth to ensure proper enclosure without pressing directly on the lens.
Table: iPhone 8 Plus key dimensions at a glance
| Dimension | In inches | Millimeters (mm) | Notes |
|---|---|---|---|
| Height (screen) | 5.5 | 139.7 | Diagonal; viewable area slightly less |
| Width (body) | 2.64 | 67.1 | Short side of the chassis |
| Depth (body) | 0.29 | 7.3 | Includes glass, metal frame, and battery |
| Weight | 7.1 oz | 202 g | Typical operational mass |
Real-world fit: pockets, bags, and one-hand use
Because the body is 2.64 inches wide and 5.5 inches tall, most full-coverage cases add a small margin that pushes total width to just over 2.75 inches and height toward 5.7 inches. For comfortable pocket fit, choose slim cases and consider rounded corners to avoid catch. The 0.29-inch depth keeps the profile low enough for standard front pockets, though the top camera bump can create a pressure point.
Comparing to predecessor and successor models
How the iPhone 8 Plus size relates to iPhone 7 Plus and iPhone X/11
The iPhone 8 Plus shares nearly identical external dimensions with the iPhone 7 Plus, adding only about 0.02 inch to height and depth due to incremental internals. Compared with iPhone X and later models, the 8 Plus is slightly thicker and heavier, reflecting earlier battery technologies and camera designs.
Guidance on cases and precise measurement
Measuring your device and choosing protective gear
Use digital calipers to confirm your unit’s exact chassis size; measure along the mid-frame on each side, and include camera bump height when selecting taller cases. If you prioritize slim fit, verify case specs against the 5.5 x 2.64 x 0.29-inch body and the approximate 3 mm camera bump to prevent cutouts that interfere with sensors or flash.
Summary and practical takeaways
The iPhone 8 Plus measures 5.5 inches tall, 2.64 inches wide, and 0.29 inch thick, with a 7.1-ounce weight that balances pocketability and grip. These dimensions help you anticipate case fit, pocket comfort, and usability with stands or mounts. Favor cases that respect the camera bump and maintain access to ports and buttons; if carrying in tight spaces, slim profiles and rounded corners will reduce bulk and snagging.
