If you’ve been eyeing the iPhone 15 Pro Max, chances are the sheer size of it crossed your mind at least once. It’s tall, it’s wide, and it definitely makes its presence known in your pocket. The question is whether those extra millimeters translate into a meaningfully larger phone, or whether you’re paying a premium for a screen that doesn’t feel dramatically different in everyday use.

How big is the iPhone 15 Pro Max?

Apple lists the iPhone 15 Pro Max at 159.9 mm tall, 76.7 mm wide, and 8.25 mm deep (Apple (official comparison tool)). Converted to imperial units, that’s 6.29 by 3.02 by 0.325 inches. The official numbers match independent measurements from Dimensions.com, which verifies these figures to four decimal places across multiple samples.

Overall dimensions

When measured as a standard rectangular shape, the iPhone 15 Pro Max sits at 159.9 mm in height, 76.7 mm in width, and 8.25 mm in thickness. The titanium frame — a first for iPhone Pro models — keeps the depth comparable to the iPhone 15 Pro while housing a larger display and battery.

  • Height: 159.9 mm (6.29 inches)
  • Width: 76.7 mm (3.02 inches)
  • Depth: 8.25 mm (0.325 inches)

In inches and mm

The iPhone 15 Pro Max’s 159.9 mm height is roughly 52 mm taller than the iPhone 15 Pro (146.6 mm / 5.77 in), making it one of the tallest iPhones Apple has ever produced. The 76.7 mm width is about 6 mm wider than its smaller sibling, which translates to noticeably more phone in your hand.

The upshot

The iPhone 15 Pro Max is the largest standard iPhone in the 2023 lineup, with the 6.7-inch display and titanium frame pushing it into “very large” territory alongside the iPhone 12 Pro Max, 13 Pro Max, 14 Pro Max, and 15 Plus (Coolblue (electronics retailer)).

Is the iPhone Pro Max 6.7 inch?

Apple rounds the screen to “6.7 inches” in marketing, but the precise diagonal measurement is 6.69 inches when measured as a standard rectangular shape, according to the official tech specs (Dimensions.com). The actual viewable area is slightly less due to the rounded corners and camera cutout.

Screen measurement details

The Super Retina XDR display spans 6.69 inches diagonally with a resolution of 2796 by 1290 pixels at 460 ppi. Apple’s official compare page lists this as “6.7-inch” for simplicity, but the precise figure matters if you’re comparing screens pixel-for-pixel.

  • Display: 6.69-inch OLED
  • Resolution: 2796 x 1290 pixels
  • Pixel density: 460 ppi
  • Peak brightness: 2000 nits

Viewable area note

The screen’s viewable area is technically less than the full 6.69 inches due to the curved corners and Dynamic Island cutout. For most practical purposes, this difference is imperceptible, but it’s worth noting if you’re measuring for a specific case or screen protector.

Why this matters

The iPhone 15 Pro Max shares the same 6.7-inch class as the iPhone 15 Plus, but the Pro Max’s ProMotion technology with adaptive refresh rates up to 120 Hz gives it a tangible advantage for scrolling and gaming (Pocket-lint (tech review publication)).

What iPhones have a 6.7 inch screen?

The iPhone 15 Pro Max shares its 6.7-inch class with four other iPhones: the iPhone 12 Pro Max, 13 Pro Max, 14 Pro Max, and 15 Plus (Coolblue (electronics retailer)). Apple has settled on two screen sizes for the standard iPhone lineup: 6.1-inch and 6.7-inch, with all Pro models in the current generation featuring the larger option.

Current models list

The iPhone 15 lineup includes four models split into two size categories. The 6.1-inch group covers the iPhone 15 and 15 Pro, while the 6.7-inch group encompasses the iPhone 15 Plus, 15 Pro Max, 14 Plus, 14 Pro Max, and the entire iPhone 13 Pro Max generation.

  • iPhone 15 Pro Max (2023) — 6.7-inch OLED
  • iPhone 15 Plus (2023) — 6.7-inch OLED
  • iPhone 14 Pro Max (2022) — 6.7-inch OLED
  • iPhone 14 Plus (2022) — 6.7-inch OLED

Pro Max series

The Pro Max designation has consistently meant the largest iPhone available since the iPhone 12 Pro Max. Each generation adds refinements: the iPhone 12 Pro Max introduced sensor-shift optical image stabilization, the 13 Pro Max brought ProMotion, and the 15 Pro Max adopted titanium for a lighter frame despite its size.

What to watch

The iPhone 15 Pro Max is larger than the iPhone XR, which has a 6.1-inch display — so if you’re upgrading from an older Plus or XR model, the size jump to 6.7 inches will be noticeable (Alibaba (consumer marketplace insights)).

How big is an iPhone 15 Pro Max in centimeters?

Converting the official millimeter measurements: the iPhone 15 Pro Max measures 15.99 cm tall, 7.67 cm wide, and 0.825 cm deep. The weight is 221 grams, or roughly 7.81 ounces. One independent measurement source (Phonetradr) confirms these figures, listing the dimensions as 159.9 mm by 76.7 mm by 8.25 mm with a weight of 221 g (Phonetradr (device database)).

Metric conversions

For international readers more familiar with centimeters than millimeters, here’s the quick reference: the height of 159.9 mm equals 15.99 cm, the width of 76.7 mm equals 7.67 cm, and the depth of 8.25 mm equals 0.825 cm. The weight of 221 g is approximately 0.221 kg. For more conversions, see our inches to cm conversion guide.

  • Height: 15.99 cm
  • Width: 7.67 cm
  • Thickness: 0.825 cm
  • Weight: 221 g

Height width depth

The iPhone 15 Pro Max’s 15.99 cm height is roughly equivalent to the length of a standard pencil, while the 7.67 cm width is close to the width of a credit card. The 0.825 cm depth is thinner than a pencil’s diameter. For context, the iPhone 15 Pro measures 14.66 cm tall — about 1.33 cm shorter than the Pro Max.

Bottom line: The iPhone 15 Pro Max is a substantial device at 15.99 × 7.67 × 0.825 cm, making it one of the largest smartphones in Apple’s current lineup. Media consumers will appreciate the screen real estate, but one-handed use requires some adjustment — especially if you’re coming from a smaller iPhone.

Is 6.7 too big for a phone?

Whether 6.7 inches qualifies as “too big” depends entirely on how you use your phone. For streaming, gaming, and productivity, the extra screen space is a genuine advantage. For single-handed texting or pocketability, the iPhone 15 Pro’s 6.1-inch display may feel more comfortable. Tech reviewers from Pocket-lint note that “the Max is the better option for streaming videos, gaming, and other tasks where screen real estate matters” — but they also observe that “the Pro is the easier phone to carry around.”

Pros and cons of large screens

The 6.7-inch display delivers a measurably better experience for media consumption. With the 2796-by-1290 resolution, text is sharper, videos display more detail, and games offer a wider field of view. The trade-off is physical bulk: at 159.9 mm tall, the iPhone 15 Pro Max is the tallest iPhone in the current lineup.

  • Pros: Better video/gaming experience, easier reading, more screen for multitasking
  • Cons: Harder to use one-handed, doesn’t fit all pockets, heavier at 221 g

User considerations

If you primarily use your phone for calls, messages, and social scrolling, the standard 6.1-inch iPhone 15 Pro likely offers a better balance. But if you’re upgrading from an older Plus-series iPhone or prioritize media viewing, the 6.7-inch screen is worth the extra size. The titanium frame keeps the weight down relative to previous stainless steel Pro Max models — at 221 g, it’s lighter than the iPhone 14 Pro Max despite the similar dimensions.

The trade-off

The Pro models use titanium alloy for a lighter frame, which is why the iPhone 15 Pro Max weighs only 7.81 ounces despite its substantial footprint. If Apple had used stainless steel at this size, the weight would likely exceed 230 g (PhoneArena (tech news outlet)).

How does iPhone 15 Pro Max compare to iPhone 15 Pro?

The iPhone 15 Pro Max is not merely a scaled-up iPhone 15 Pro — it has exclusive features beyond the larger screen. The Pro Max includes a tetraprism telephoto lens with 5× optical zoom, while the iPhone 15 Pro maxes out at 3×. Battery capacity also favors the Max, and storage options start at 256 GB rather than 128 GB.

Specification iPhone 15 Pro Max iPhone 15 Pro
Height 159.9 mm (6.29 in) 146.6 mm (5.77 in)
Width 76.7 mm (3.02 in) 70.6 mm (2.78 in)
Depth 8.25 mm (0.325 in) 8.25 mm (0.325 in)
Weight 221 g (7.81 oz) 187 g (6.6 oz)
Screen Size 6.69 inches 6.1 inches
Resolution 2796 x 1290 2556 x 1179
Base Storage 256 GB 128 GB
Starting Price $1,199 $999

The iPhone 15 Pro Max is the larger sibling in every meaningful dimension: 13.3 mm taller, 6.1 mm wider, and 34 g heavier. The larger body also means a larger battery, which translates to longer runtime per charge — Apple rates the Pro Max at up to 29 hours of video playback versus 23 hours for the Pro.

Detailed Technical Specifications

Eight measurements from three independent sources converge on the same figures for the iPhone 15 Pro Max, with Apple itself confirming the height and width on its official comparison tool. The screen resolution of 2796 by 1290 pixels appears consistently across Apple’s tech specs, Dimensions.com, and Pocket-lint.

Category Specification Value
Dimensions Height 159.9 mm / 6.29 in
Dimensions Width 76.7 mm / 3.02 in
Dimensions Depth 8.25 mm / 0.325 in
Weight Mass 221 g / 7.81 oz
Display Diagonal 6.69 in / 170 mm
Display Resolution 2796 x 1290 px
Display Pixel Density 460 ppi
Display Peak Brightness 2000 nits
Build Frame Material Titanium
Build Rated IP68

The titanium frame marks a departure from the stainless steel used in previous Pro Max models, reducing weight without compromising structural rigidity. Apple maintains IP68 dust and water resistance across all iPhone 15 Pro models, meaning the iPhone 15 Pro Max can survive submersion in up to 6 meters of water for 30 minutes.

Is the iPhone 15 Pro Max Worth the Size Premium?

The iPhone 15 Pro Max commands a $200 premium over the iPhone 15 Pro, with the size difference being the most obvious physical manifestation of that price gap. Whether the extra screen real estate and longer battery life justify the cost depends on your usage patterns.

Upsides

  • 6.7-inch display beats 6.1-inch for video, games, and reading
  • Longer battery life (up to 29 hours video playback)
  • 5× optical zoom (tetraprism lens exclusive to Pro Max)
  • Base 256 GB storage versus 128 GB
  • Lighter titanium frame than previous Pro Max generations

Downsides

  • Taller frame harder to use one-handed
  • Doesn’t fit in smaller pockets or phone holders
  • 221 g weight noticeable during extended use
  • $200 more than iPhone 15 Pro for same chip and camera main specs

The titanium frame keeps the iPhone 15 Pro Max surprisingly light for its size — at 221 g, it’s only 34 g heavier than the iPhone 15 Pro despite having a significantly larger display and battery. In previous generations, the Pro Max models used heavier stainless steel, which pushed weight above 240 g. The material shift makes the 2023 model feel less burdensome than its predecessors.

“The larger size means the Max weighs more, 7.81 ounces compared to 6.6. That makes the iPhone 15 Pro the easier phone to carry around, but the Max the better option for streaming videos, gaming, and other tasks where screen real estate matters.”

— Pocket-lint (tech review publication)

“Pro models are made with titanium, making them lighter and their edges thinner than last year’s.”

— PhoneArena (tech news outlet)

Apple offers four regional variants of the iPhone 15 Pro Max: US/Puerto Rico (eSIM only), Japan/Canada/Saudi Arabia/Guam/USVI/Mexico (physical SIM + eSIM), Hong Kong/Macau/China (dual physical SIM), and Global (Singapore/Korea/India/UAE and others). Physical dimensions are identical across all variants, so regional buyers don’t need to account for size differences when choosing a model.

The catch

Regional variants differ only in SIM capability and legal compliance — not in physical dimensions. The 159.9 mm height, 76.7 mm width, and 8.25 mm depth remain constant whether you buy in Tokyo, London, or New York (YouTube (regional variants breakdown)).

If you’re moving from an older Plus or standard iPhone, the iPhone 15 Pro Max’s 6.7-inch screen represents a meaningful upgrade in media capability. The 2796-by-1290 resolution and 460 ppi density make text and images crisper than older iPhones with lower pixel counts. But if one-handed usability is non-negotiable, the 6.1-inch iPhone 15 Pro delivers the same A17 Pro chip and camera system in a more pocketable package.

For buyers deciding between the iPhone 15 Pro and iPhone 15 Pro Max, the size premium is real — both in price ($200) and physical footprint (13.3 mm taller, 6.1 mm wider, 34 g heavier). The titanium frame mitigates some of the weight penalty, but the Pro Max remains a two-handed device for most users. The trade-off between screen size and pocketability is a personal one, and Apple’s official comparison page lets you view both models side-by-side before committing.
