iPhone 7 Plus size is 158.2 × 77.9 × 7.3 mm and 188 g; the screen is 5.5 inches.
The iPhone 7 Plus sits in that large-phone zone many shoppers still like. You get a tall 5.5-inch display, a roomy body for two cameras, and a shape that favors landscape video and gaming. If you’re here for the plain numbers, they’re right up top. If you’re comparing fit, reach, weight, pockets, or a case you already own, the rest of this guide breaks it down in human terms so you can decide fast.
How Big Is The iPhone 7 Plus? Size Breakdown
Quick check: Height is 6.23 inches (158.2 mm), width is 3.07 inches (77.9 mm), thickness is 0.29 inch (7.3 mm). Weight is 6.63 oz (188 g). The display measures 5.5 inches on the diagonal at 16:9 with 1920 × 1080 pixels at 401 ppi. These numbers come from Apple’s tech specs and match retail listings.
Put next to many modern phones, the body looks big because of the top and bottom bezels. The flat sides are gentle, the corners are round, and the camera block is small compared to newer phones. The front has a Home button with Touch ID, which adds a chin and slightly shifts your thumb travel.
People often type “how big is the iphone 7 plus?” when they want to know if a used model will feel unwieldy. In hand, it’s closer to today’s 6.1–6.3-inch full-screen phones because of the bezels. The edges are smooth and the back is metal, which can feel slippery without a case. If you measure with a ruler, trace a 158 × 78 mm rectangle on paper; that footprint mirrors the outline with just enough margin for the curves.
Screen, Bezels, And Reach
Screen feel: The 5.5-inch LCD is bright and sharp at 401 ppi. Color is wide gamut (P3), and max brightness hits 625 nits in Apple’s testing. Text stays crisp, and the 16:9 shape suits video that fills the screen without pillar bars.
Reach zones: One-hand reach to the top corners is tough unless you have large hands. Apple’s Reachability helps by pulling the UI lower. Two-hand typing feels natural because the phone’s width gives your thumbs room.
Bezel tradeoff: The forehead and chin add length without adding screen. That extra frame keeps accidental touches down and makes landscape grip stable. It also means the overall device is larger than a modern edge-to-edge 6.1-inch phone even though the display is smaller.
Comfort tweaks: Bump text size one notch, enable Bold Text, and try Display Zoom if you want larger tap targets. Those changes don’t alter the body, but they make the big screen easier to scan while walking or commuting.
Weight, Grip, And Pockets
Balance: At 188 g, the iPhone 7 Plus is solid but not brick-like. The weight spreads evenly, so it doesn’t feel top-heavy when you shoot photos with the telephoto lens.
Grip tips: The matte finishes resist smudges; Jet Black is glossy and grippy but shows wear. A thin TPU case adds traction and a lip around the camera while keeping bulk down. Rounded sides are comfy, and the 7.3 mm frame slides into jeans without snagging.
Pocket test: Front pockets are fine; back pockets are risky when you sit. In slimmer trousers, the width can print. A cross-body sling or small handbag slot fits it well.
Hand size notes: If your hand span is under 19 cm, plan on two-hand use for long sessions. Over 21 cm, top-row taps are easier, yet the width still makes a case with side ridges helpful on bumpy train rides.
Case Fit And Accessory Notes
Case swaps: iPhone 7 Plus and iPhone 8 Plus are close in size. Many cases labeled for one will fit the other because the camera layout and button positions align. The 8 Plus is a hair taller, wider, and thicker, and it’s heavier due to the glass back. Flexible cases tend to fit both; hard shells are hit-or-miss.
Screen protectors: Flat glass with 2.5D edges works best. Full-coverage films designed for the 8 Plus generally align with the 7 Plus front glass cutouts.
Mounts and grips: The flat back pairs well with slim grips. Car mounts that clamp the sides hold steady because the rails are straight. A bike mount with a strap is safer than magnetic plates on a thin case.
Wireless add-ons: The 7 Plus lacks built-in wireless charging, so wallet cases with magnets don’t need MagSafe alignment. If you stick a plate for a magnetic mount, place it low enough to avoid NFC taps near the top edge.
Size Compared To Other iPhones
Fast context: The iPhone 8 Plus is almost the same footprint, just a bit heavier and thicker. The smaller iPhone 7 drops the second camera and shrinks in every dimension. Here’s a quick size table for shopping and case checks.
| Model | HxW×D (mm / inches) | Weight |
|---|---|---|
| iPhone 7 Plus | 158.2 × 77.9 × 7.3 / 6.23 × 3.07 × 0.29 | 188 g (6.63 oz) |
| iPhone 8 Plus | 158.4 × 78.1 × 7.5 / 6.24 × 3.07 × 0.30 | 202 g (7.13 oz) |
| iPhone 7 | 138.3 × 67.1 × 7.1 / 5.44 × 2.64 × 0.28 | 138 g (4.87 oz) |
What the numbers mean: The Plus models share width. That’s why thumb reach feels similar on both, and why many car mounts and grips are interchangeable. The 8 Plus adds glass for wireless charging, so weight rises by about 14 g. If you’re sensitive to heft, you’ll feel that in long reading sessions.
Pocket feel vs. modern phones: A recent 6.1-inch edge-to-edge phone is shorter and narrower while offering more screen. If you’re moving from a compact device, the 7 Plus will stretch pockets and might nudge you toward a cross-body carry or a jacket pocket on travel days.
Carry And Use Tips
Reading and media: The 16:9 display fills with YouTube and older TV shows with no letterboxing. In landscape, the body becomes a steady grip for streaming and games. Stereo speakers fire from the bottom and the earpiece, which helps when you’re not using earbuds.
Photo work: The larger shell lets Apple fit two rear cameras: wide and 2× telephoto. Portrait mode is present, and the phone stays stable in both hands. The mass actually helps dampen shake.
Typing: Split-thumb typing is easy in portrait, and the wider deck in landscape turns it into a small keyboard. Reachability helps if you’re scrolling long pages with one hand. A light, grippy case helps.
- Test your reach — Hold the phone as you normally grip it and try the top corner of Control Center. If you miss, enable Reachability in Settings.
- Pick a thin case — Choose 1–1.5 mm TPU for grip without bulk. You keep pocket slide while adding drop protection.
- Add a lanyard loop — A looped case or strap reduces hand strain when commuting or taking photos one-handed.
- Choose a wide mount — For cars or bikes, clamp styles with rubber pads spread weight evenly across the sides.
- Mind the pocket — Skip back-pocket carry. The long body puts pressure on the frame when you sit.
Plenty of buyers also type “how big is the iphone 7 plus?” because they’re weighing it against a compact phone for travel. If pocket space is tight, the smaller iPhone 7 drops bulk but loses the telephoto lens and some battery headroom. If you want the dual camera and can live with a larger frame, the Plus gives you that reach and a roomier canvas for maps and media.
Specs That Shape The Feel
Build: Aluminum back with curved edges keeps the frame thin. IP67 water resistance helps in rain and spills, but don’t charge it wet. The SIM tray sits on the right side; case cutouts rarely block it.
Display details: 1920 × 1080 pixels on 5.5 inches produces 401 ppi. That density keeps small UI text readable at arm length. The panel supports Display Zoom and dual-domain pixels for wide viewing angles.
Buttons and ports: You get a Lightning port, a ring/silent switch, and clicky volume and power buttons. There’s no 3.5 mm jack. If you clip a mic pack or dongle, a case with a roomy bottom cutout helps.
Longevity notes: Apple classifies the model as vintage in some regions, which can affect parts availability at official service providers. Third-party shops still handle batteries and screens, so daily use is practical if the size suits you.
Before you buy:
- Check published size — Compare the store listing to the dimensions above. If numbers differ, the listing may be for a case or a different model.
- Ask about weight — A screen swap or heavy case can add grams. If weight matters to you, request a scale photo.
- Test pocket fit — Bring a paper template to the shop. Slide it into your tightest pocket to see how the corners sit.
