Across its three generations, the iPhone SE measures from 4.87 inches to 5.45 inches tall, depending on the exact model you own.
If you type “How long is an iPhone SE in inches?” you are usually trying to answer one of three questions: how tall the phone is, whether it will fit a pocket or bag, and if a case or accessory will match your exact model. Length in this context means height from top edge to bottom edge, not the diagonal screen size.
How Long Is An iPhone SE In Inches Across Models?
Apple has released three iPhone SE generations so far. The first one uses the older 4-inch body, while the second and third generations share the taller 4.7-inch shell. That difference explains why some people still call the original SE a “small phone” and the later versions “compact but not tiny.”
- iPhone SE (1st generation, 2016) height — 4.87 inches tall, 2.31 inches wide, and about 0.30 inch thick.
- iPhone SE (2nd generation, 2020) height — 5.45 inches tall, 2.65 inches wide, and 0.29 inch thick.
- iPhone SE (3rd generation, 2022) height — 5.45 inches tall, 2.65 inches wide, and 0.29 inch thick, almost identical in size to the 2020 model.
Apple lists these numbers on its official iPhone SE (3rd generation) tech specs, and the same measurements apply to the 2020 SE as well. The original 2016 SE keeps the much shorter 4.87-inch frame carried over from the iPhone 5s, which is why cases built for that era look too small on the later phones.
If you are standing in a store or looking at a friend’s device, the easiest way to remember the sizes is this: the tiny, boxy SE from 2016 is under five inches tall, while the rounded-edge SE models from 2020 and 2022 are a little over five and a half inches tall.
iPhone SE Length, Width, And Thickness At A Glance
Length tells you how tall the phone is, yet width and thickness matter for grip comfort and for tight pockets. All three generations are fairly slim, though the first SE is noticeably narrower and shorter than the later ones.
| Model | Height (inches) | Width (inches) |
|---|---|---|
| iPhone SE (2016) | 4.87 | 2.31 |
| iPhone SE (2020) | 5.45 | 2.65 |
| iPhone SE (2022) | 5.45 | 2.65 |
The third number Apple gives is thickness. The 2016 SE is around 0.30 inch thick, while the 2020 and 2022 phones are just under that at 0.29 inch. In practice the difference in thickness is hard to notice, especially once you add a case, yet the jump in height and width from the 2016 model to the later ones feels very clear in one hand.
If you shop online, case listings often quote the diagonal screen size instead of the body length. The original SE uses a 4-inch display, while the 2020 and 2022 SE models use a 4.7-inch display in the same 5.45-inch tall shell. When a listing says “for 4.7-inch iPhone SE,” it means it will not fit the older 4.87-inch tall body.
How To Tell Which iPhone SE Size You Have
Before you measure or order accessories, it helps to confirm whether you own the small 2016 SE or one of the taller 2020 or 2022 models. They share the same name on the box, so a quick visual and settings check saves time.
- Check The Overall Shape — The 2016 iPhone SE has squared edges and looks like an iPhone 5s. The 2020 and 2022 SE phones share the rounded edges and glass back of the iPhone 8.
- Look At The Screen — On the original SE the bezels feel chunky even by older standards, with a compact 4-inch screen. The later SE models have a taller 4.7-inch screen with the same size bezels you see on an iPhone 8.
- Check Model Info In Settings — On your iPhone, open Settings > General > About and find the Model Name and Model Number. You can cross-reference that against Apple’s identify your iPhone model page to see which generation you have.
Once you know the generation, you can safely rely on the official height figures. Any first-generation SE you still have in a drawer will stand at 4.87 inches, while any SE that resembles an iPhone 8 will be the taller 5.45-inch body.
Measuring Your iPhone SE Length Yourself
If you want to double-check the length in inches at home, a simple ruler or tape measure does the job. You do not need calipers to get a reading that is close enough for case shopping or pocket planning.
- Place The Phone On A Flat Surface — Set the iPhone SE face up on a desk or table so it does not wobble, with the top edge aligned roughly with the zero mark on your ruler.
- Measure From Top Edge To Bottom Edge — Line the ruler along the side of the phone and read the length where the bottom edge ends. You should see just under 5 inches for a 2016 SE, or just over 5.4 inches for a 2020 or 2022 SE.
- Check Width If Needed — Turn the phone ninety degrees and measure across. The narrow 2016 SE will read a little over 2.3 inches, while the later models land near 2.65 inches.
- Note The Numbers For Cases — Write down the height and width and match them against product pages when you buy cases, screen protectors, or bike mounts.
Small measurement errors from a soft tape or a slightly crooked ruler will not change your buying decision. Accessories built for the 4.87-inch body simply do not stretch to the 5.45-inch shell, and parts meant for the taller phones feel loose on the older SE.
Why iPhone SE Length Matters For Daily Use
Phone length seems like a dry spec sheet number until you live with the device in tight pockets, small bags, and one-handed use. The jump from 4.87 inches to 5.45 inches changes how the phone carries and how far your thumb has to stretch.
Pocket And Bag Fit
The 2016 SE slips into shallow jeans pockets and small cross-body bags with little effort because it is both shorter and narrower. People who daily drive this model often mention that it almost disappears in a pocket.
The 2020 and 2022 SE models still feel compact compared with modern giant phones, yet they sit higher in a pocket. In tight denim, the taller body can press against the pocket edge when you sit down. If you pick trousers mainly for pocket depth, knowing that your SE stands at 5.45 inches tall helps you avoid that dig-in feeling.
One-Handed Reach
Length also affects thumb reach. On the original SE, most people can tap the far corners without sliding the phone down their hand. On the taller SE generations, many users need to shift their grip slightly to reach the very top of the screen, especially inside apps with buttons near the status bar.
If you often type or scroll while holding a bag or a handrail, that extra half inch of body length can decide whether a phone feels easy or slightly awkward to use all day.
Choosing Cases And Accessories By iPhone SE Size
Case makers often group the 2020 and 2022 SE together because their size and shape match. The first-generation SE, on the other hand, lives in its own size class. Knowing the exact length in inches keeps you away from returns and wasted orders.
Case Shopping Tips
- Match The Listed Model Years — Look for labels such as “for iPhone SE 2020 / 2022” or “for iPhone SE 1st gen / iPhone 5s.” If a product only lists the 4.7-inch SE, it will not fit the original 4.87-inch body.
- Check Height And Width Figures — When a seller shows dimensions, confirm that they align with 4.87 x 2.31 inches for the first SE or 5.45 x 2.65 inches for the later ones.
- Watch For Shared Molds — Many rugged cases reuse the iPhone 8 mold for the 2020 and 2022 SE. That works because those phones have the same 5.45-inch tall shell and button layout.
Screen Protectors And Mounts
- Use SE-Specific Glass — Tempered glass for the 2016 SE follows the smaller 4-inch panel and does not cover a 4.7-inch screen correctly. The same is true in reverse.
- Check Clamp Ranges On Mounts — Many bike or car mounts list a height range in inches. Make sure the clamp can close down to around 4.9 inches for the original SE, or open to at least 5.5 inches for the later phones.
- Allow Room For A Case — If your mount feels tight with a bare SE, a thick case will add a few millimeters. Picking a mount with a bit of headroom avoids daily squeezing.
How iPhone SE Length Compares To Other iPhones
When you see the numbers side by side, the iPhone SE line sits on the smaller end of Apple’s recent phones. Even the taller 5.45-inch SE remains shorter than many current models with six-inch displays.
The original 4.87-inch SE lines up with older compact phones such as the iPhone 5s and iPhone 5. The 5.45-inch SE body matches the iPhone 8 and is still shorter than recent devices that hover near six inches or more in height. That makes any SE a reasonable choice if you care about reach and comfort more than a massive screen.
If you upgrade from the 2016 SE to the 2020 or 2022 SE, expect a clear change in how your phone sits in hand and in your pockets. Moving from a 5.45-inch SE to one of the larger modern phones adds another jump in length that you will notice every time you slip it into a pocket or reach for the top row of icons.
