The iPhone 16 lineup is Apple’s most size-diverse generation in years, with four distinct models spanning from a compact 6.1-inch screen to a massive 6.9-inch display. But screen size is only one number, and it’s often the least useful when you’re trying to figure out whether a phone will fit your hand, your pocket, or your car mount. The physical dimensions—height, width, and thickness—tell the real story.
The confusion around iPhone dimensions usually comes from mixing up different measurements. Apple lists screen size diagonally, but the device itself has separate height, width, and depth figures. There’s also the camera bump, which adds depth beyond the official thickness number. And there’s the weight, which varies dramatically across the lineup and affects how the phone feels in daily use.
This guide breaks down every dimension of all four iPhone 16 models in inches, millimeters, and centimeters. You’ll get real-world comparisons to help you picture each size, answers to the questions people actually ask about fit and feel, and a clear picture of which model is right for your hands.
The standard iPhone 16 measures 5.81 inches tall, 2.82 inches wide, and 0.31 inches thick (147.6 mm × 71.6 mm × 7.8 mm) and weighs 170 grams (6.00 ounces).
That’s the base model. But the Plus, Pro, and Pro Max all have their own dimensions, so let’s walk through the full lineup.
Every iPhone 16 Model’s Dimensions Convert To
Here’s how all four iPhone 16 models break down across every unit people search for.
| Model | Height (mm / in) | Width (mm / in) | Thickness (mm / in) | Weight (g / oz) |
|---|---|---|---|---|
| iPhone 16 | 147.6 mm / 5.81 in | 71.6 mm / 2.82 in | 7.8 mm / 0.31 in | 170 g / 6.00 oz |
| iPhone 16 Plus | 160.9 mm / 6.33 in | 77.8 mm / 3.06 in | 7.8 mm / 0.31 in | 199 g / 7.02 oz |
| iPhone 16 Pro | 149.6 mm / 5.89 in | 71.5 mm / 2.81 in | 8.25 mm / 0.32 in | 199 g / 7.02 oz |
| iPhone 16 Pro Max | 163.0 mm / 6.42 in | 77.6 mm / 3.06 in | 8.25 mm / 0.32 in | 227 g / 8.01 oz |
The math here follows standard conversion rules. To get inches from millimeters, divide by 25.4. So 147.6 mm ÷ 25.4 = 5.81 inches. The width of 71.6 mm ÷ 25.4 = 2.82 inches. And the thickness of 7.8 mm ÷ 25.4 = 0.31 inches.
The screen sizes are separate measurements. The iPhone 16 and 16 Plus have 6.1-inch and 6.7-inch displays respectively, while the Pro models use 6.3-inch and 6.9-inch screens. But those diagonal figures don’t tell you how the phone feels in your hand—the physical dimensions do.
The camera bump adds depth beyond the official thickness. On the Pro models, the camera module protrudes roughly 0.05 to 0.1 inches beyond the back panel, which matters if you’re checking whether the phone sits flat on a table.
Where Each iPhone 16 Model Sits on the Size Chart
The iPhone 16 lineup splits into two clear categories: the standard models (16 and 16 Plus) and the Pro models (16 Pro and 16 Pro Max).
iPhone 16 is the most compact model in the lineup. At 5.81 inches tall and 2.82 inches wide, it’s slightly taller than the iPhone 15 it replaces but essentially the same width. The 170-gram weight makes it the lightest of the four, which matters for one-handed use and pocket comfort.
iPhone 16 Plus shares the same thickness as the standard 16 but stretches to 6.33 inches tall and 3.06 inches wide. That extra width is the critical difference—it’s nearly a quarter-inch wider than the standard model, which pushes it out of comfortable one-handed territory for many users.
iPhone 16 Pro is a surprising entry. At 5.89 inches tall and 2.81 inches wide, it’s slightly taller than the standard 16 but actually a hair narrower. The Pro’s thickness increases to 8.25 mm (0.32 inches), and the weight jumps to 199 grams—29 grams heavier than the standard 16. That weight comes from the titanium frame and the more advanced camera system.
iPhone 16 Pro Max is the largest iPhone ever made. At 6.42 inches tall and 3.06 inches wide, it’s slightly taller than the iPhone 15 Pro Max it replaces. The 227-gram weight makes it the heaviest of the four by a significant margin. If you’re upgrading from an older Pro Max, expect a noticeable increase in heft.
The key takeaway is that width, not height, determines one-handed usability. The standard 16 and 16 Pro are both around 2.81 inches wide, which is manageable for most hands. The Plus and Pro Max stretch to 3.06 inches, which requires larger hands or a two-handed grip for comfortable use.
11 Things That Measure Around the iPhone 16
Since the standard iPhone 16 is 5.81 inches tall and 2.82 inches wide, here are eleven everyday references that land close to those dimensions.
A Standard Index Card (5×8 Inches)
A 5×8 index card measures 5 inches wide and 8 inches long. The iPhone 16 is 5.81 inches tall and 2.82 inches wide. So the phone is taller than the card’s width but narrower than its length. Lay the phone on the card and it extends about 0.8 inches beyond the short edge.
A Dollar Bill Folded in Half
A US dollar bill measures 6.14 inches long. The iPhone 16 is 5.81 inches tall—about a third of an inch shorter than a dollar bill. If you hold a bill next to the phone, the bill extends slightly beyond the top and bottom edges. It’s one of the closest everyday height references.
A Standard Credit Card
A credit card measures 3.37 inches tall and 2.125 inches wide. The iPhone 16 is 2.82 inches wide—noticeably wider than a credit card by about 0.69 inches. The phone’s height of 5.81 inches is much taller than the card’s 3.37 inches.
A Standard Chocolate Bar
A standard chocolate bar measures about 6 inches long and 3 inches wide. The iPhone 16 at 5.81 × 2.82 inches is slightly shorter and narrower than the bar, but the difference is small. A chocolate bar is one of the closest everyday footprint matches for the standard iPhone 16.
A Stack of 10 Credit Cards
A single credit card is about 0.03 inches thick. Ten cards stacked would measure roughly 0.30 inches—almost exactly the thickness of the iPhone 16 at 0.31 inches. That’s a useful way to picture the phone’s profile, though the camera bump adds extra depth in one spot.
A Standard Smartphone from 2018
An iPhone XS from 2018 measured 5.65 inches tall and 2.79 inches wide. The iPhone 16 is slightly taller at 5.81 inches but almost identical in width. The main difference is weight—the iPhone XS weighed 177 grams, slightly heavier than the 170-gram iPhone 16.
A Standard TV Remote (Width)
A typical TV remote measures about 2 inches wide and 8 inches long. The iPhone 16 at 2.82 inches wide is wider than the remote, but its 5.81-inch height is shorter than the remote’s length. The remote gives you a partial match at best.
A Standard Pocket Notebook
A small pocket notebook typically measures 3.5 inches wide and 5.5 inches tall. The iPhone 16 at 2.82 inches wide and 5.81 inches tall is narrower but taller. If you carry a pocket notebook, the phone is about the same height but noticeably slimmer.
A Standard Pen (Length)
A typical ballpoint pen measures 5.5 to 6 inches long. The iPhone 16’s height of 5.81 inches falls right in that range. The phone is much wider and flatter than a pen, but the height comparison is solid.
A Standard Kitchen Sponge
A kitchen sponge measures about 4.5 inches long, 3 inches wide, and 1 inch thick. The iPhone 16 is taller (5.81 inches) and narrower (2.82 inches) than the sponge’s width, and much thinner at 0.31 inches. It’s a partial match at best.
A Standard Passport
A passport measures 4.9 inches wide and 3.5 inches tall when closed. The iPhone 16 is taller at 5.81 inches but narrower at 2.82 inches. The dimensions don’t align well—a passport is wider and shorter than the phone.
The “Which iPhone 16 Size Is Right for Me?” Question People Actually Mean
When people search for iPhone 16 dimensions, they’re usually not just curious about the numbers. They’re trying to decide which model to buy, and the dimensions are the most reliable way to compare. The real question is about comfort, fit, and usability.
One-handed use. The standard iPhone 16 and iPhone 16 Pro are both around 2.81 inches wide, which is the threshold for comfortable one-handed use for most adults. If you have average or larger hands, you can reach across the screen with your thumb without shifting your grip. The Plus and Pro Max at 3.06 inches wide push past that threshold—most people will need to adjust their grip or use two hands for anything beyond basic scrolling.
Pocket fit. All four models fit in standard front pockets, but the Plus and Pro Max dominate the pocket space. The standard 16 at 5.81 inches tall leaves room for keys or a wallet in the same pocket. The Pro Max at 6.42 inches tall and 227 grams makes its presence felt every time you sit down.
Weight. This is where the Pro models differentiate themselves. The standard 16 at 170 grams is light enough to forget it’s in your pocket. The Pro at 199 grams is noticeably denser. The Pro Max at 227 grams is the heaviest iPhone ever made—if you’re used to a lighter phone, the adjustment period is real.
Cases and accessories. The iPhone 16 and iPhone 16 Pro have nearly identical widths (2.82 vs. 2.81 inches), but the Pro is slightly taller and thicker. Cases are not interchangeable between models. The Plus and Pro Max have identical widths at 3.06 inches, but their heights differ by 0.09 inches, so cases aren’t interchangeable there either.
Camera bump. The Pro models have a larger camera module that protrudes more than the standard models. If you use the phone flat on a table without a case, the Pro models will wobble slightly. The standard models are more stable.
Getting to These Dimensions Without a Tape Measure
If you don’t have a ruler handy, here are a few ways to estimate the iPhone 16’s size using things you already have.
Use a dollar bill. A dollar bill is 6.14 inches long. The iPhone 16 is 5.81 inches tall—about a third of an inch shorter. Lay a bill next to the phone and the difference is roughly the width of a pencil eraser.
Use a credit card. A credit card is 2.125 inches wide. The iPhone 16 is 2.82 inches wide—about two-thirds of an inch wider. Stack one and a half credit cards side by side and you’re close to the phone’s width.
Use a stack of paper. A standard ream of printer paper is 2 inches thick. The iPhone 16 at 0.31 inches is about one-sixth of that thickness. Five stacks of 50 sheets each would be roughly 0.8 inches—still thicker than the phone.
Use a chocolate bar. A standard chocolate bar is about 6 inches long and 3 inches wide. That’s very close to the iPhone 16’s 5.81 × 2.82-inch footprint. If you have a candy bar nearby, it’s one of the best everyday size references.
Use your hand span. The average adult hand span is about 8 inches for men and 7 inches for women. The iPhone 16’s height of 5.81 inches is shorter than most hand spans, meaning you can hold the phone comfortably in one hand for reading—but reaching the top corners with your thumb is a different challenge.

Where That Leaves You
The iPhone 16 lineup spans four distinct sizes, from the compact 5.81-inch standard model to the massive 6.42-inch Pro Max. The standard iPhone 16 measures 5.81 inches tall, 2.82 inches wide, and 0.31 inches thick, weighing 170 grams. The Pro models add thickness and weight—the Pro Max at 227 grams is the heaviest iPhone ever made.
The strongest everyday comparison for the standard iPhone 16 is a standard chocolate bar, which measures roughly 6 inches long and 3 inches wide, nearly matching the phone’s footprint. A dollar bill is also a useful height reference, landing just a third of an inch longer than the phone.
For quick visualization, remember that the iPhone 16 is slightly shorter than a dollar bill, wider than a credit card by about two-thirds of an inch, and about as thick as 10 stacked credit cards. If one-handed use matters to you, the 2.82-inch width of the standard and Pro models is the number to focus on—that’s the threshold for comfortable thumb reach across the screen.
