No, the iPhone 16 is slightly taller and thicker than the iPhone 13, so cases and screen protectors don’t swap cleanly.
If you’re moving from an iPhone 13 to an iPhone 16, “same size” sounds simple. In real life, a millimeter here or there decides whether your case snaps on, your screen protector lines up, and your car mount grips the phone without wobble. This guide sticks to hard measurements, then turns those numbers into everyday answers you can act on.
Quick Size Verdict
The iPhone 16 and iPhone 13 share the same general footprint, yet they are not identical. The iPhone 16 is taller and a touch thicker, while the iPhone 13 is a bit shorter and slimmer. That tiny shift is enough to make most iPhone 13 cases a poor fit on an iPhone 16, and it can leave screen protectors slightly misaligned.
There’s one spot where the two phones feel close. Width is nearly the same, so hand feel and pocket feel stay familiar. Still, accessory fit is about more than width. Cutouts, camera bumps, button placement, and edge shape can break compatibility even when the display size looks the same on paper.
iPhone 16 And iPhone 13 Size Comparison With Real Numbers
Apple posts exact dimensions for both models. For the iPhone 16, the official technical specs list 147.6 mm tall, 71.6 mm wide, and 7.80 mm deep, with a 170 g weight and a 6.1-inch display. You can verify those figures on Apple’s iPhone 16 technical specifications page.
For the iPhone 13, Apple lists 146.7 mm tall, 71.5 mm wide, and 7.65 mm deep, with a 174 g weight and a 6.1-inch display on its iPhone compare page.
| Model | Body Size (H × W × D) | Display Size |
|---|---|---|
| iPhone 16 | 147.6 × 71.6 × 7.80 mm | 6.1-inch |
| iPhone 13 | 146.7 × 71.5 × 7.65 mm | 6.1-inch |
What those numbers mean in plain terms is easy to miss. The iPhone 16 is 0.9 mm taller, 0.1 mm wider, and 0.15 mm thicker. That sounds tiny. Still, case tolerances are tight, and camera cutouts are even tighter. Even a small mismatch can keep the phone from sitting flush or can press the side buttons in weird ways.
What stays the same
Both phones use a 6.1-inch display size on the spec sheet, and the width is almost identical. So the “general” size category is the same. If you liked how the iPhone 13 carried in a pocket, the iPhone 16 won’t feel like a different class of phone.
What changes enough to matter
Height and thickness changes are where accessory fit starts to fail. A case built around the iPhone 13’s shorter body can leave a tiny gap at one end on an iPhone 16, or it can bind at the corners. A screen protector designed to end right at the bezel line on an iPhone 13 can shift just enough to show a sliver of uncovered glass, or it can crowd the edge and lift once a case lip presses against it.
Will Your iPhone 13 Case Fit An iPhone 16?
In most situations, it won’t fit well. Even if you can force it on, a “forced fit” tends to create a few predictable problems: corners that don’t seat, a case that creaks when you grip it, and buttons that feel mushy or stuck.
Why cases rarely transfer cleanly
- Body height mismatch — The case’s top and bottom lips are molded to the exact edge position, so a taller phone can stretch the fit and leave gaps.
- Side button placement drift — Even a small shift can make a button cover land off-center, which changes click feel.
- Camera area geometry — Camera cutouts are built to hug the bump. If the bump layout differs, the case can block a lens, a flash, or the microphone area.
If you’re tempted to reuse a favorite iPhone 13 case because it cost a lot, do a quick safety check after you try it. Wiggle the phone at each corner, press every side button ten times, then take a few photos with flash in a dim room. If anything feels off, that case is a risk for drops and bad button wear.
Two edge cases where a swap can seem to work
Some ultra-flexible silicone cases can stretch enough that the phone “seems” seated. Some bumper-style cases with open top and bottom can also hide a height mismatch. Still, you’re gambling with button alignment and camera clearance. If you keep the case, check photo results and button feel over a few days, not just for five minutes.
Will Your iPhone 13 Screen Protector Fit An iPhone 16?
Screen protectors are less forgiving than cases. If the glass shape, edge curve, or sensor area differs, a protector that looks close can still fail at the edges. You might get bubbles that never leave, or the protector can lift once a case presses against it.
Common fit issues you’ll notice fast
- Edge lift — The protector sits fine at first, then a corner starts to peel after a day in a pocket.
- Case interference — A case lip catches the protector edge and slowly pries it up.
- Misaligned top cutout — The front sensor area ends up partially covered or leaves a visible offset.
If you already installed a leftover iPhone 13 protector on an iPhone 16, watch the edges under bright light. If you see a thin rainbow line along an edge, that’s usually early lift. Replace it now while the screen is still clean and scratch-free.
How The Size Shift Feels In Real Use
Numbers tell you compatibility. Feel tells you daily comfort. The iPhone 16’s extra height is small, yet it can show up in one-handed use, especially if you rely on thumb reach near the top of the display.
One-handed reach
If you type with one hand and you often hit the top-left corner, the taller body can push that reach just out of your natural thumb arc. You can adapt by using Reachability or by shifting grip, yet it’s still a change you’ll notice in the first week.
Pocket and bag carry
The width staying almost the same is why both phones feel close in jeans pockets. The extra height can matter in tight pockets, like slim-fit front pockets, or in small crossbody bags where the phone sits upright in a narrow sleeve.
Weight difference
The iPhone 16 is listed at 170 g, while the iPhone 13 is listed at 174 g. That means the newer phone can feel a hair lighter, even while being a touch thicker. In day-to-day use, most people register shape and grip more than a 4 g difference.
Accessory Compatibility Beyond Cases And Protectors
Even if you accept that you’ll buy a new case, you might still wonder about everything else you own. Chargers, mounts, and stands can be fine, yet a few accessory types are picky about width, thickness, or button placement.
Magnetic chargers and magnetic wallets
Magnetic accessories usually still “stick,” but alignment matters. If the magnet ring inside your old case is placed for an iPhone 13, it can sit slightly off on an iPhone 16 case, which can change how securely a wallet holds or how well a charger centers.
Clamp-style car mounts
Clamp mounts care about thickness more than height. A thicker phone plus a thicker new case can push a mount near its limit. That can lead to slower clamping, less grip, or side pressure on buttons.
- Measure your mount opening — Check the widest gap the clamp can handle, then compare it to your phone-plus-case thickness.
- Set clamp pads carefully — Many mounts have sliding pads that can avoid pressing on side buttons.
Gimbals and stabilizers
Gimbals usually balance by weight and center position. A slightly different body shape can shift balance enough that you need to redo the clamp position. It’s not hard, yet you should test it before filming a long clip.
Desktop docks and stands
Stands with a tight slot can reject a thicker phone in a thick case. If your stand has a narrow groove, try it with the case you plan to use on the iPhone 16, not just with the bare phone.
Quick Ways To Confirm Fit Before You Spend Money
Retail listings can be messy, and many sellers re-use photos across models. A quick check on your side can save a return cycle and a scratched screen.
Measurement check you can do at home
- Use a ruler or caliper — Measure your iPhone 13 case interior height and compare it to 147.6 mm as a target for the iPhone 16 body height.
- Check camera cutout clearance — Look at the cutout shape and compare it to the phone’s camera area opening once you see an iPhone 16 photo from a straight-on angle.
- Test button feel on your iPhone 13 — Press the case’s button covers lightly and note how much travel they allow, since tight cases are less forgiving on a new model.
Shopping check that filters out the wrong listings
- Match the exact model name — Look for “iPhone 16” on the listing title, not “fits iPhone 13/14/15/16.”
- Read the return notes — Confirm you can return it if the fit is off after installation.
- Scan recent reviews — Look for buyer photos that show button alignment and camera cutout shape.
In-store test that takes under a minute
If you can handle an iPhone 16 at a retailer, do a quick feel test with your own habits. Hold it one-handed, swipe down Control Center, reach the top of Safari, and type a short message. You’ll know fast whether the extra height changes comfort for you.
Should You Upgrade If Size Familiarity Is Your Main Concern?
If you like the iPhone 13 size, the iPhone 16 stays close enough that you won’t feel like you switched to a “Plus” model. The shift is subtle. The bigger change is accessory reset. Plan on a new case and a new screen protector, and you’ll avoid the annoying half-fits that lead to scratches and loose corners.
If you want the smoothest transition, treat the move like a small re-kit. Pick a case style you already like, buy the matching iPhone 16 version, and pair it with a protector designed to work with that case lip. Your grip memory will stay intact, and you won’t waste money on “maybe” compatibility.
Quick shopping checklist
- Choose a case first — Protector edge shape depends on how far your case lip wraps the glass.
- Buy a protector made for iPhone 16 — It’s the easiest way to avoid edge gaps and sensor cutout issues.
- Re-test your mount — Clamp mounts and gimbals can need a small adjustment when case thickness changes.
- Keep your iPhone 13 kit as backup — That old case is still handy if you use the iPhone 13 as a spare phone.
The iPhone 16 is not the same size as the iPhone 13, yet it still feels familiar. Use the measurements above to plan your accessory swap and skip the “almost fits” trap.
