iPhone size should be compared with body dimensions and weight, not
screen diagonal alone. Thin bezels allow a newer phone to fit a larger
display into a body close to an older model. The table below covers
commonly compared iPhone 15, iPhone 16 and third-generation iPhone SE
models; verify Apple’s live comparison page for later releases.
iPhone size chart
| Model | Display | Height | Width | Depth | Weight |
|---|---|---|---|---|---|
| iPhone SE (3rd gen.) | 4.7 in | 138.4 mm | 67.3 mm | 7.3 mm | 144 g |
| iPhone 15 | 6.1 in | 147.6 mm | 71.6 mm | 7.8 mm | 171 g |
| iPhone 15 Plus | 6.7 in | 160.9 mm | 77.8 mm | 7.8 mm | 201 g |
| iPhone 15 Pro | 6.1 in | 146.6 mm | 70.6 mm | 8.25 mm | 187 g |
| iPhone 15 Pro Max | 6.7 in | 159.9 mm | 76.7 mm | 8.25 mm | 221 g |
| iPhone 16 | 6.1 in | 147.6 mm | 71.6 mm | 7.8 mm | 170 g |
| iPhone 16 Plus | 6.7 in | 160.9 mm | 77.8 mm | 7.8 mm | 199 g |
| iPhone 16 Pro | 6.3 in | 149.6 mm | 71.5 mm | 8.25 mm | 199 g |
| iPhone 16 Pro Max | 6.9 in | 163.0 mm | 77.6 mm | 8.25 mm | 227 g |
Dimensions are based on Apple technical specifications. A case adds
width, depth and weight.
Which iPhone is smallest?
The third-generation iPhone SE is the smallest model in this table,
with a 67.3 mm width and 4.7-inch display. Its older design includes a
Home button and larger top and bottom bezels. Buyers should also check
current software-support and sales status.
Among the listed all-screen models, iPhone 15 Pro has the narrowest
body at 70.6 mm. A difference of one millimeter can be noticeable in
one-handed use.
Which iPhone has the
largest screen?
iPhone 16 Pro Max has a 6.9-inch diagonal display in the listed
group. It is also the tallest and heaviest. The iPhone 15 Pro Max and
Plus models use 6.7-inch displays, while the iPhone 16 Plus also uses
6.7 inches.
A large screen helps with video, maps, reading and keyboard space,
but it makes pockets, one-handed reach and long holding less comfortable
for some users.
iPhone 16 versus iPhone 16
Pro size
iPhone 16 has a 6.1-inch display and weighs 170 g. iPhone 16 Pro
increases the display to 6.3 inches, is slightly taller, almost the same
width, thicker and heavier at 199 g. The Pro therefore adds screen area
without becoming as wide as a Plus model.
Choose on camera, performance and display features as well as
dimensions. Size alone does not explain the price difference.
Plus versus Pro Max
Plus and Pro Max models both target buyers who want a large screen.
The Plus is generally lighter, while Pro Max adds professional camera
and display features and more weight. Compare the exact generation
because screen sizes and materials differ.
If weight matters, hold the phone with the intended case. A
protective case and grip accessory can move a comfortable phone beyond
the preferred limit.
How should you choose the
right size?
Measure the current phone and note what causes discomfort. Width
affects grip, height affects pocket fit and top-screen reach, and weight
affects prolonged reading. Screen diagonal mainly describes viewing
area.
Print a correctly scaled outline or compare devices in a store. Test
typing, reaching the top corner, taking a photo and holding it for
several minutes. Accessibility features such as Display Zoom and
Reachability can help but do not change physical size.
Will old cases fit a newer
iPhone?
Do not assume so, even when height and width look similar. Camera
modules, button positions, speaker openings and thickness can change.
Buy a case listed for the exact model number.
Use Apple’s current compare and technical-specification pages before
purchase, especially after a new launch. This chart is a reference for
the models named, not a substitute for checking a later generation.
