Buying a case online without checking the iPhone 12 Pro Max dimensions first? The result is a half a millimeter out-of-square case that can’t be snapped closed. It does occur more often than some will acknowledge.
This phone is big. Larger than many people realize until they get a first-hand look. Let’s get to the actual numbers: height, width, thickness, weight, everything — what they are and what they really mean once the phone is in your hands.
What Are the iPhone 12 Pro Max Dimensions?
Apple lists the iPhone 12 Pro Max dimensions as 6.33 inches tall, 3.07 inches wide, and 0.29 inches deep. Convert that to millimeters and you get 160.8 x 78.1 x 7.4. Heavy at 226 grams or roughly 7.97 ounces, which is quite heavy as compared to the images.
It was Apple’s largest phone on launch day back in 2020, and despite the upgrades, it’s bigger when it comes to size. The later Pro Max models made relatively little change in terms of height and width. It has been the Apple standard to add weight and thickness with each camera update.

iPhone 12 Pro Max Dimensions Visually
Specs on paper don’t tell you much until you’ve actually felt the thing. So picture this instead: stand the phone next to a TV remote — pretty close in height. Line up three golf tees end to end and that’s roughly the width. For thickness, stack two AA batteries flat and you’re basically there.
Or just grab a deck of playing cards. Hold it in your palm. That’s close to the footprint of the iPhone 12 Pro Max — just stretched out a bit taller and a lot thinner.

Most third-party case makers list dimensions in millimeters, not inches. Keep this table open in another tab if you’re shopping overseas — it’ll save you a return shipment.
iPhone 12 Pro Max Size Compared to Other iPhones
Numbers mean more with something to compare them against. Here’s how the iPhone 12 Pro Max lines up next to its closest siblings.
| Model | Height | Width | Depth | Weight |
| iPhone 12 Pro Max | 6.33 in | 3.07 in | 0.29 in | 226 g |
| iPhone 12 Pro | 5.78 in | 2.82 in | 0.29 in | 189 g |
| iPhone 12 mini | 5.18 in | 2.53 in | 0.29 in | 135 g |
| iPhone 13 Pro Max | 6.33 in | 3.07 in | 0.30 in | 240 g |
| iPhone 14 Pro Max | 6.33 in | 3.05 in | 0.31 in | 240 g |
See how tight that height and width column stays? Apple basically froze the Pro Max footprint for three generations. The only real shift is a few grams of extra weight each year — camera hardware isn’t light.
Screen Size and Display Details
At 6.7 inches diagonally, the Super Retina XDR display was the largest Apple had shipped up to that point, and it’s a big reason the phone’s body needed to be this size in the first place. You can’t fit a screen that big into a smaller shell.
Resolution sits at 2778 x 1284, with 458 pixels per inch. Even by today’s standards that’s sharp — sharp enough that text still looks crisp and video still looks great, years after this thing left the shelf.
How to Measure iPhone 12 Pro Max Size Without a Ruler
No tape measure? No problem. A standard credit card is roughly as wide as the phone. Stack two credit cards end to end and you’re close to matching its height. For thickness, two stacked coins get you in the ballpark of that 7.4 mm depth.
These tricks come in handy more than you’d think — especially when you’re eyeing a case online at 1 a.m. and just want a gut check before hitting buy.
Why iPhone 12 Pro Max Dimensions Matter
Size changes how a phone actually lives with you day to day. Pocket fit. One-hand reach. Whether a case makes it feel like a brick. All of that traces back to the iPhone 12 Pro Max dimensions listed above.
People jumping from an iPhone mini straight to a Pro Max are usually the ones most caught off guard — it’s a real size jump, not a subtle one. That said, the tradeoff is a genuinely bigger canvas for video, reading, and gaming. Worth it for some people. Not for others. Knowing the numbers ahead of time just means you’re not guessing.
Apple iphone 12 Pro Max 14th Gen Case Fit and Compatibility
The size of the case is almost the same as the iPhone 13 Pro Max, so many Pro Max cases will fit on the iPhone 13. This is where the two models are different, and you can find yourself in a situation where the camera cutout exposes the lens or covers it. Before purchasing be sure to check the dimensions of the camera as well as its size.
