iPhone 15 Pro Max official dimensions

Apple publishes exact measurements for every iPhone, and the 15 Pro Max is no exception. Here’s the full spec sheet straight from the manufacturer.

The implication: every number above is directly from Apple’s tech-specs page — no guesswork. The 15 Pro Max is a tall, narrow phone that’s surprisingly thin for its screen size.

How big is my iPhone 15 Pro Max in cm?

If you’re used to metric measurements, here’s the same data converted to centimetres.

For perspective, the 15 Pro Max is about as wide as a standard credit card (85.6 mm) but taller than most compact notebooks. Its depth is roughly the thickness of a stack of 8 business cards. The screen diagonal of 16.95 cm matches the 6.7-inch display size Apple advertises, though the actual viewable area is slightly smaller due to the rounded corners.

Is the iPhone 16 Pro Max the same size as the 15 Pro Max?

Apple hasn’t announced the iPhone 16 Pro Max yet, but early leaks suggest it could be slightly larger. Based on supply-chain rumours aggregated by PhoneArena (tech news), the new model might measure 6.31 inches tall and 3.08 inches wide — a minor increase in width. Until Apple’s official release, nothing is certain. What we do know is that the 15 Pro Max is almost identical in size to the 14 Pro Max, with one major difference: weight.

The pattern: the 15 Pro Max is actually 0.04 inches shorter and 0.03 inches narrower than the 14 Pro Max, but 0.01 inch thicker. The real headline is weight — the 15 Pro Max is 19 grams lighter, thanks to the titanium frame replacing stainless steel. That’s a 7.9% reduction reported by PhoneArena (tech news). For anyone who carries their phone all day, that difference is noticeable.

The trade-off: case compatibility between 14 Pro Max and 15 Pro Max is hit-or-miss. The 15 Pro Max’s camera bump is slightly different, so some cases designed for the 14 may not fit perfectly around the lens.

Which iPhones are 6.7 inches?

Apple has used a roughly 6.7-inch display on its largest Pro Max models since the iPhone 12 Pro Max. Here’s the full list of iPhones with that screen size.

A few smaller iPhones also share a similar screen size category: the iPhone 15 Plus and iPhone 14 Plus also have 6.7-inch displays, but with lower specs (60 Hz refresh rate, no ProMotion). Apple Compare.

What this means: if you’re upgrading from a 6.7-inch iPhone 13 Pro Max, the 15 Pro Max’s screen is essentially the same size — the difference is in weight and camera performance, not physical dimensions.

Is 6.7 too big for a phone?

There’s no universal answer. The iPhone 15 Pro measures 6.1 inches diagonally (Apple Compare), which is a common “compact” size. The 6.7-inch screen adds about 0.6 inches to each dimension, making the phone noticeably larger in hand.

• One-handed use: Most people with average-sized hands cannot comfortably reach the top-left corner of a 6.7-inch screen. Reachability (double-tap the Home Indicator) helps, but it’s not as seamless as a smaller phone.
• Portability: The 15 Pro Max fits in most pockets, but it extends noticeably above a typical jeans pocket. Some users report it’s fine; others find it uncomfortable when sitting.
• Screen real estate: A larger display means more room for video, maps, and split-screen multitasking. For anyone who frequently watches content or works on spreadsheets, the extra space is a genuine advantage.

For a comparison with a truly compact device, the iPhone 15 Pro Max is about 21 mm taller and 10 mm wider than the iPhone 15 Pro. That’s about the width of two stacked credit cards.

The implication: the 6.7-inch size is not for everyone. If you prioritize one-handed comfort above all else, the 6.1-inch iPhone 15 Pro or the 5.8-inch iPhone 13 mini might serve you better. If you value screen space and don’t mind using two hands, the 15 Pro Max delivers the biggest canvas Apple offers without sacrificing weight.

Frequently asked questions

For anyone deciding between the iPhone 15 Pro Max and a smaller model, the numbers are clear: you get a 6.7-inch screen in a body that’s taller than a credit card but notably lighter than the previous generation. If you’re coming from an iPhone 14 Pro Max, you’ll notice the 19-gram weight drop immediately. If you’re upgrading from a 6.1-inch phone, be prepared for a stretch — both in reach and in pocket fit. The 15 Pro Max is an excellent device for screen-first users, but it demands two-handed use.
