Are iPhone 11 and 12 the Same Size? | Same Screen, New Shape

At a glance, the iPhone 11 and iPhone 12 look like they should fit the same case, the same pocket, and the same hand. That’s where plenty of buyers get tripped up. Apple gave both phones a 6.1-inch display, so the screen class matches. The body does not.

The iPhone 11 measures 150.9 mm tall, 75.7 mm wide, and 8.3 mm thick. The iPhone 12 comes in at 146.7 mm tall, 71.5 mm wide, and 7.4 mm thick. That makes the iPhone 12 4.2 mm shorter, 4.2 mm narrower, and 0.9 mm thinner. It also drops from 194 grams to 164 grams, which is a 30-gram cut you can feel the second you pick it up.

So if your question is about screen size, the answer is close to “yes.” If your question is about body size, cases, grip, or pocket feel, the answer is “no.” That split is the whole story here, and it matters more than many spec sheets make it sound.

Why These Two Phones Get Mixed Up So Often

Apple made this one easy to misread. The product pages for both phones list a 6.1-inch display. That single number sticks in people’s heads, so they assume the shell stayed the same too. It didn’t.

The iPhone 11 uses a rounded frame with thicker bezels around the screen. The iPhone 12 moved to flatter sides and slimmer borders. That let Apple keep the display size while shaving down the body. You get the same class of screen area, yet less phone around it.

That’s why someone can hold both models and say, “These look close,” then still notice that one slips into a jeans pocket more cleanly. The iPhone 12 trims the extra bulk from nearly every edge. On paper, a few millimeters can sound tiny. In your palm, they don’t.

Are iPhone 11 and 12 the Same Size? In Real Use

They are not the same size in any practical sense that affects accessories or comfort. A case for the iPhone 11 will not fit the iPhone 12 properly. Screen protectors are also not a safe swap, since the front shape and bezel layout differ. Even when you manage to line one up, the cutouts and edges won’t sit right.

Grip is where the difference shows up fast. The iPhone 11 has a softer, rounder feel and a chunkier body. The iPhone 12 feels trimmer from side to side, and the flat rails can make it seem more planted when you hold it. Some people read that as more secure. Others find the older rounded body friendlier for long scrolling sessions. That part comes down to taste, but the size gap is still there.

Weight changes the feel too. Thirty grams is not a spec-sheet footnote. It changes how the phone sits in a jacket pocket, how it feels during one-handed texting, and how much wrist fatigue you get during a long FaceTime call or a late-night video binge.

Screen Size Vs Body Size

This is the bit that clears up most confusion. “6.1-inch display” tells you the diagonal measurement of the visible screen area. It does not tell you the phone’s outer height, width, thickness, bezel size, or frame shape. Two phones can share the same display class and still have different bodies.

That’s exactly what happened here. Apple lists both models with a display that measures 6.06 inches diagonally as a standard rectangle, yet the surrounding hardware changed. The iPhone 12 also jumps from the iPhone 11’s Liquid Retina LCD panel to a Super Retina XDR OLED panel. That upgrade affects sharpness and contrast, but for this size question, the bigger point is bezel efficiency. The screen stayed in the same class while the housing shrank.

What Changes In Your Pocket Or Bag

If you carry your phone in slim pants, a small crossbody bag, or a crowded coat pocket, the iPhone 12 feels easier to stash. The narrower body makes the biggest difference. A shorter height helps too when you sit down and the phone presses against the top of your pocket.

The iPhone 11 is still manageable. It just feels more like a solid slab. That extra thickness adds to the sense of heft. Add a rugged case, and the older phone starts to feel chunky in a hurry.

For body dimensions and display details, Apple’s official iPhone 11 technical specifications and iPhone 12 technical specifications show the measurements side by side once you break them out line by line.

Side-By-Side Size Differences That Matter Day To Day

Specs are useful, but they land better when you translate them into daily use. The chart below does that. It doesn’t just show the raw numbers. It shows what those numbers change when the phone leaves the box and becomes part of your day.

Measure Or Fit Point	iPhone 11	iPhone 12
Display class	6.1-inch screen	6.1-inch screen
Height	150.9 mm	146.7 mm
Width	75.7 mm	71.5 mm
Thickness	8.3 mm	7.4 mm
Weight	194 g	164 g
Frame feel	Rounded sides	Flat sides
Display type	LCD	OLED
Pocket feel	Bulkier	Trimmer
Case sharing	No match with 12	No match with 11

The row that tells the whole story is width. A 4.2 mm drop sounds modest until you wrap your fingers around both phones. Width changes comfort more than most people expect, since that’s the dimension your hand fights all day.

Thickness comes next. The iPhone 12 loses less than a millimeter, yet that trim pairs with the lower weight and flatter sides, so the phone feels slimmer than the raw figure suggests. The iPhone 11 is not huge by old “Plus” standards, though next to the 12 it feels denser and rounder.

Where The Same-Size Idea Still Holds Up

There is one part of the “same size” claim that holds water: the viewing class. Both phones sit in the same 6.1-inch tier, so a buyer choosing between them is not moving up or down in screen category. Apps, webpages, and videos live in a familiar footprint.

That matters when you worry about text size, typing room, or whether the display will feel cramped. It won’t. If you liked the general screen area on the iPhone 11, the iPhone 12 will not feel like a step down in that sense.

Still, screen category is only half the buying call. The iPhone 12 packs a higher-resolution OLED panel with denser pixels, so text and dark scenes look cleaner. The iPhone 11’s LCD is still pleasant, but the newer phone squeezes more display quality into a smaller shell. That combo is why these two phones feel close in use, even while their bodies are plainly different.

Will Cases, Sleeves, And Mounts Interchange?

Cases are an easy no. The camera bump shape, button placement, edge profile, and body dimensions all block a clean swap. A soft sleeve might fit both if it has enough slack, but that’s about tolerance, not true compatibility.

Car mounts and bike mounts depend on how they grip the phone. Adjustable clamps can work with either model. Molded cradles made for one model should stay with that model. If you use accessories with tight tolerances, treat the iPhone 11 and iPhone 12 as separate sizes.

Accessory Question	What To Expect	Best Move
Hard shell case	Does not swap cleanly	Buy model-specific case
Screen protector	Poor edge and cutout fit	Match the exact phone
Loose pouch or sleeve	May fit both	Check internal room
Clamp-style mount	Often works with either	Measure clamp range
Molded dock or cradle	Fit can fail	Use the listed model

Which One Feels Bigger In The Hand

The iPhone 11 feels bigger. Not by a mile, but enough that most people notice it within a minute. The extra width spreads across your grip. The added thickness and weight finish the job.

The iPhone 12 can feel more squared off because of the flat sides, so “smaller” does not always read as “softer.” Still, once you move past the edge shape, the 12 is the leaner phone. If hand comfort or pocketability sits high on your list, that leaner build is a real plus.

There’s also a small mental trick at work. Since both screens are in the same class, your eyes say “same phone size.” Your hand says something else. That split is why this question keeps coming up years after both models launched.

Should Size Alone Push You Toward One Model

If you already own an iPhone 11 and want a phone that feels less bulky without dropping to a smaller display class, the iPhone 12 makes a neat step. You keep the 6.1-inch viewing tier and lose some body mass. That’s the sweet spot for plenty of people.

If you like a rounder grip and do not care much about shaving off width or weight, the iPhone 11 still feels solid and familiar. Some users even prefer its softer edges when holding the phone for long stretches.

So, are iPhone 11 and 12 the same size? They match in screen category, but not in outer dimensions or feel. For shopping, accessory fit, and daily handling, treat them as different sizes. That will save you from buying the wrong case, the wrong protector, or the wrong replacement based on a single 6.1-inch label.
