iPhone 17 Pro Max Height and Width
The iPhone 17 Pro Max height and width make it a tall, wide phone.
It is about 0.3 inch longer than a US dollar bill, which is 6.14 inches. It is also a bit narrower than the long side of a credit card, which is 3.37 inches.
iPhone 17 Pro Max Thickness and Camera Bump
The body is 0.34 inch (8.75 mm) thick. The camera plateau on the back adds more, so the full depth reaches about 13.13 mm, or just over half an inch.
That raised plateau is why the top edge sits slightly higher when the phone lies flat on a desk.
Why Sources Show Slightly Different Numbers
You may see 8.8 mm listed for thickness. That is simply 8.75 mm rounded up.
Apple also notes that size and weight vary by configuration and manufacturing process. A gap of a gram or a fraction of a millimeter is normal.

The Super Retina XDR OLED screen packs 2868 x 1320 pixels. That gives a pixel density of 460 ppi.

iPhone 17 Pro Max vs iPhone Air
The Air is only 0.22 inch thick, about 0.12 inch slimmer. It is also about 2.4 ounces lighter.
The Pro Max wins on screen size. The Air wins on slim, light portability.

Both have 6.9-inch screens. The newer model is about 0.4 mm taller, 0.4 mm wider, and 0.5 mm thicker. It is also 6 grams heavier.

Is the iPhone 17 Pro Max Too Big?
Is the iPhone 17 Pro Max too big? It depends on how you hold and carry it.
One-Handed Use and Thumb Reach
At 3.07 inches wide, your thumb reach covers the lower half of the screen and the side your thumb is on.
The top and far edge need a second hand. You can also turn on Reachability in Settings, then swipe down on the bottom edge.
Pocket Fit in Jeans and Pants
The phone fits most men’s jeans, but it takes up the whole pocket. Women’s pockets are often smaller, so it may not fit at all.
When you sit or bend, the camera plateau and tall body can press into your hip. Deep pockets help.
Case, Screen Protector, and Accessory Fit
Buy cases and screen protectors made for the iPhone 17 Pro Max. The camera plateau and Camera Control button are specific to this model.
Check MagSafe alignment too. MagSafe and Qi2 charging both reach up to 25W.
Who Should Choose the Pro Max?
The Pro Max suits people who watch a lot of video or shoot with the 48MP Pro Fusion camera system. Apple lists up to 39 hours of video playback.
If pocketability and one-hand use matter more, the iPhone 17 Pro or iPhone Air fit better.
