iPhone 17 Pro Max Dimensions & Size (Inches, MM, CM)
The iPhone 17 Pro Max size puts it firmly in “two-hand phone” territory. Here’s exactly how it measures up.
iPhone 17 Pro Max Size in Inches
The phone measures 6.43 inches tall, 3.07 inches wide, and 0.35 inches thick. In metric terms, that’s 163.4 x 78 x 8.8mm. Around the camera housing, the thickness grows to roughly 0.52 inches (13.3mm), since the rear camera module sits proud of the glass back.
That extra camera bump matters more than people expect. It’s the main reason the phone can rock slightly when placed flat on a table, and it’s something to keep in mind if you skip a case.
iPhone 17 Pro Max Weight
At 233 grams (8.22 ounces), this is one of the heaviest iPhones Apple has ever shipped. For comparison, that’s noticeably heavier than most Android flagships in the same screen-size class, and about 35 grams heavier than the standard iPhone 17.
iPhone 17 Pro Max Screen Size — Is It 6.9 Inches?
Yes. The iPhone 17 Pro Max screen size is 6.9 inches, measured diagonally, with a 1320 x 2868 pixel resolution and roughly 460 pixels per inch. This is the same screen size Apple used on the iPhone 16 Pro Max, so the display itself hasn’t grown — the surrounding chassis has.
| Measurement | Inches | Millimeters |
|---|---|---|
| Height | 6.43 in | 163.4 mm |
| Width | 3.07 in | 78.0 mm |
| Thickness | 0.35 in | 8.8 mm |
| Thickness (camera bump) | ~0.52 in | ~13.3 mm |
| Weight | 8.22 oz | 233 g |
| Screen size | 6.9 in | 175.3 mm |
iPhone 17 Pro Max Full Specifications (2026)
Size is only half the story. Here’s what’s actually powering the device.
Display, Chip & Performance
The phone runs on Apple’s A19 Pro chip, built on a 3nm process, paired with a 6-core CPU and 6-core GPU. The display itself is an LTPO Super Retina XDR OLED panel with 120Hz ProMotion, HDR10, Dolby Vision, and peak brightness up to 3,000 nits outdoors — a meaningful jump for visibility in direct sunlight.
Camera System
The rear setup uses a triple 48MP camera array: a 24mm wide lens, a 100mm periscope telephoto lens offering 4x optical zoom, and a 13mm ultra-wide lens. A LiDAR scanner supports depth sensing for portrait shots and AR apps. The front camera jumps to 18MP.
Battery Life & Charging
Battery capacity sits at 4,823mAh, supporting 25W wireless charging via MagSafe or Qi2, and wired charging that reaches 50% in about 20 minutes. Apple also added reverse wired charging, letting the phone top up accessories like AirPods.
iPhone 17 Pro Max RAM & Storage
The iPhone 17 Pro Max RAM sits at 12GB across every storage tier. Storage options run from 256GB up to a massive 2TB, giving creators and heavy multitaskers real headroom for 4K ProRes footage without constantly managing space.

iPhone 17 Pro Max vs iPhone 16 Pro Max: What Changed in Size
This is the comparison most upgraders actually care about.
Size & Weight Difference
The iPhone 16 Pro Max measured 163 x 77.6 x 8.25mm and weighed 227 grams. The iPhone 17 Pro Max grew to 163.4 x 78 x 8.8mm and 233 grams. That’s a gain of 0.4mm in height, 0.4mm in width, roughly 0.5mm in thickness, and 6 grams in weight.
Is the 17 Pro Max Bigger Than the 16 Pro Max?
Yes, but only slightly. The size increase is small enough that most people won’t notice it just by holding the two phones. Where you will feel the difference is the weight, since 6 extra grams adds up over a full day of one-hand use.
Screen Size Difference
Here’s the surprise: there isn’t one. The iPhone 16 Pro Max also used a 6.9-inch LTPO XDR OLED display running at 120Hz with a resolution of 1320 x 2868 pixels — identical to the 17 Pro Max. The extra bulk comes from the chassis and camera hardware, not a bigger panel.
| Spec | iPhone 16 Pro Max | iPhone 17 Pro Max |
|---|---|---|
| Dimensions | 163 x 77.6 x 8.25mm | 163.4 x 78 x 8.8mm |
| Weight | 227g | 233g |
| Screen size | 6.9 in | 6.9 in |
| Chip | A18 Pro | A19 Pro |
| Max storage | 1TB | 2TB |
iPhone 17 Pro Max Size in Real Life: Pockets, Cases & One-Hand Use
Specs on paper are one thing. Daily carry is another.
Does It Fit in Jeans Pockets?
Most standard men’s jeans pockets can handle the phone, though it takes up the entire pocket space. Slim-fit jeans and most women’s jeans pockets, which run narrower, will feel noticeably tighter. Sitting down with the phone in a front pocket can also press the camera bump into your hip.
One-Hand Usability & Thumb Reach
With a 6.43-inch height and 3.07-inch width, reaching the top corners of the screen with one thumb during one-hand use is not realistic for most hand sizes. The bottom half of the display stays comfortably reachable. Apple’s Reachability feature, triggered by swiping down on the home bar, helps bridge that gap.
Case & Accessory Compatibility
Cases and screen protectors made for the iPhone 16 Pro Max will not fit the 17 Pro Max cleanly, since the camera cutout position and bump height changed. Anyone upgrading should buy accessories rated specifically for this model, including MagSafe wallets and car mounts, since even a 0.4mm shift can cause misaligned cutouts.
Is the iPhone 17 Pro Max Too Big? Who Should Buy It
There’s no universal right answer here — it depends on how you actually use your phone.
Best For
Media watchers, mobile gamers, and anyone shooting or editing video will get the most value from the larger 6.9-inch display and bigger battery. The extra screen real estate also helps with split-screen multitasking and reading dense documents.
Consider the iPhone 17 Pro or iPhone Air Instead If
If one-hand use, pocket comfort, or lighter overall weight matter more to you than screen size, the standard iPhone 17 Pro (6.3-inch, 206g) or the iPhone Air (6.5-inch, 165g) are considerably easier to carry day to day.
