Compare iPhone 16 Pro and iPhone 16 Pro Max viewport sizes, physical resolution, and display shape for mobile testing.
At a glance
Values combine reference display records and calculated geometry. Rounded corners, cutouts, hinges, browser UI, and device modes can change the usable area.

Visual comparison
Compare physical screen proportions and native pixel grids, or switch to CSS viewport references for responsive-layout work. Every drawing uses one shared scale so the relative size remains meaningful.
CSS viewport comparison
Compare two devices to see the relative area.
iPhone 16 Pro
iPhone · DPR 3 · 460 PPI
iPhone 16 Pro Max
iPhone · DPR 3 · 460 PPI
Proportional comparison of iPhone 16 Pro and iPhone 16 Pro Max using physical screen dimensions, CSS viewport references, or native pixel grids.
Decision factors
The Pro Max adds both physical size and usable reference width and height.
Both use DPR 3 and approximately 460 PPI, so the larger model adds pixels while preserving density.
Browser chrome, text size, orientation, and accessibility settings can still change the live result.

A winner applies only to the stated task. Read the limitation before treating it as a complete product recommendation.
Practical considerations
Methodology and sources
Physical dimensions are calculated from diagonal and aspect ratio. Named-product hardware claims use manufacturer specifications; CSS viewports remain practical browser references.
How the geometry is calculated
Width and height divide the diagonal using the stated aspect ratio. Screen area is width × height, and PPI divides the diagonal pixel count by the diagonal inches.

Frequently asked questions
It usually provides more visible space, but browser UI and text size settings still affect the viewport.
Yes. Larger viewport height or width can change where sticky elements, cards, and CTAs appear.
For important mobile designs, showing both a smaller and larger iPhone reference is useful.
Using these portrait references, the 440 × 956 Pro Max viewport has about 20% more CSS area than the 402 × 874 Pro viewport.
Not by PPI in these official specifications. Both are listed at 460 PPI; the Pro Max adds physical size and pixels while retaining similar density.
