Truly compact smartphones are a dying breed, with screen sizes seemingly growing with every passing year.
As such, there aren’t as many small smartphones as there once were, but there are still some and there is still a market for them – though what we’re considering small has also changed over the years.
With that in mind we’ve created this guide, highlighting the best compact options available at a range of budgets. We’ve split it into sections, the first covers high-end phones, the second mid-rangers, and the third affordable phones, so if you’re after a compact phone just jump to the section that best suits your budget.
Our list includes everything from the truly tiny iPhone SE 3rd Gen, to the high-end Samsung Galaxy Z Flip 3 and iPhone 13 Mini, among many other phones.
And if you simply want the smallest smartphone possible, we’ve got you covered there too, as we’ve also dug up the smallest one we can find that’s currently available.
For the purposes of this list we’re loosely counting anything with a screen size of 6 inches or under as small. That said, some phones pack big screens into small bodies, so at times larger screen sizes might squeeze in if the overall handset is still small.
5.4-inch display and 131.5 x 64.2 x 7.7mm
The iPhone 13 Mini is Apple’s compact flagship for 2021, and it’s a lot like the iPhone 12 Mini (which you’ll find elsewhere in this list), as the iPhone 13 range aren’t as big upgrades as we see some years from Apple.
That said, it is still an upgrade, and still therefore better. It has an incredibly powerful A15 Bionic chipset, which should top not just older iPhones, but just about every Android phone too.
It also has a 20% smaller notch than the iPhone 12 Mini, so the design looks a bit better. Battery life is better too, coming in at up to 17 hours when watching videos, and the cameras have been improved as well, with new hardware and modes, such as Cinematic video, for seamless focus shifting when shooting.
Beyond that, the iPhone 13 Mini has a 5.4-inch 1080 x 2340 OLED screen, 5G, MagSafe support, water resistance, and up to 512GB of storage, so there’s a lot of space on this little phone.
6.7-inch display and 86.4 x 72.2 x 15.9-17.1mm / 166 x 72.2 x 6.9mm
The Samsung Galaxy Z Flip 3 5G has by far the biggest screen of any phone in this list at 6.7 inches. Indeed, a 6.7-inch display is far from compact, but the Galaxy Z Flip 3 5G can fold in half, bringing its dimensions down to a much more pocket-friendly size. In fact, while it’s quite thick like this, it’s otherwise the smallest phone on this list.
Of course, while folded down you can’t use the 6.7-inch screen, but you still have access to a 1.9-inch 260 x 512 secondary screen. So it’s compact and still useable, but when you want to properly focus on it you can make it much bigger and access a 1080 x 2640 AMOLED display with a 120Hz refresh rate.
That’s a high-end spec, and so are many of the Samsung Galaxy Z Flip 3 5G’s other specifications. It supports 5G of course, and has a high-end Snapdragon 888 chipset, plus water resistance, a capable dual-lens camera, 8GB of RAM, and a stylish, eye-catching design.
5.8-inch display and 144 x 71.4 x 8.1mm
The iPhone 11 Pro is no longer the best iPhone, but unlike its successors – the iPhone 12 Pro and iPhone 13 Pro – this one with its 5.8-inch display is just about small enough to be considered a compact handset.
It’s in many ways a lot like the iPhone XS, but there have been some key improvements.
Chief among them is perhaps the camera, which now has an extra lens, giving you a 12MP main, a 12MP ultra-wide, and a 12MP telephoto lens to play with.
The iPhone 11 Pro also has a much longer-lasting battery, and has had a significant power boost, thanks to Apple’s newer A13 Bionic chipset.
It’s not the biggest of upgrades but these along with a few other tweaks are enough to ensure it’s a top phone – though overall the iPhone 13 Mini is arguably the better compact iPhone.
5.9-inch display and 148 x 68.5 x 8.9mm
The Asus Zenfone 8 straddles the line between mid-range and flagship, as it pairs high-end specs with a slightly more affordable price than most rivals, and with its 5.9-inch screen it’s also compact.
That’s a 1080 x 2400 Super AMOLED display with 120Hz refresh rate and HDR10+ support, so it’s a high-end screen. It’s not quite as high resolution as some flagships, but being compact the pixels go further.
There’s no compromise on the power front though, with a top-end Snapdragon 888 chipset and up to 16GB of RAM powering the phone, and you also get up to 256GB of storage, an in-screen fingerprint scanner, and a 4,000mAh battery.
The main way in which this doesn’t quite feel like a flagship is its dual-lens camera, but its 64MP main sensor and 12MP ultra-wide both perform well, so it’s an acceptable compromise for the price.
5.4-inch display and 131.5 x 64.2 x 7.4mm
Apple looks to be bringing back compact phones, as it launched both the iPhone SE (2020) and the iPhone 12 Mini in the same year, and they both have very small screens by modern smartphone standards.
The iPhone 12 Mini has just a 5.4-inch screen, and it’s coupled with a premium design with very little bezel, so it really is very small in the hand.
Its specs are anything but mini though, as the iPhone 12 Mini has an enormously powerful A14 Bionic chipset, a flagship quality dual-lens camera, a durable, highly water resistant build, and a sharp 1080 x 2340 OLED display. It’s no longer Apple’s best compact phone, but it’s still very good.
4.7-inch display and 138.4 x 67.3 x 7.3mm
The iPhone SE 3rd Gen is an exciting phone, as it’s a mid-range iPhone with 5G. In fact, it’s the first mid-range iPhone with 5G. So as well as being compact (which this very much is thanks to its tiny 4.7-inch screen), the iPhone SE 3rd Gen is also the cheapest 5G iPhone.
Not only that but it’s very powerful too, as it has an A15 Bionic chipset, which you’ll also find in the iPhone 13 range.
Beyond that, the iPhone SE 3rd Gen is similar to its predecessor, with an admittedly rather dated design – one which means that it’s not quite as small as it could otherwise be, thanks to large bezels.
But with a capable 12MP camera, superb software, and all the speed that 5G and its chipset bring, this is easily one of the best compact smartphones – especially if you’re shopping for something mid-range.
6.0-inch display and 153 x 67 x 8.3 mm
The Sony Xperia 10 IV is Sony’s main 2022 mid-ranger, and it’s essentially a smaller, lower spec version of the Sony Xperia 1 IV.
With a 6.0-inch screen it just squeezes onto our list, but it’s worth noting that this is a tall screen with a 21:9 aspect ratio. As a result this is the tallest phone we’ve included, but it’s also narrower than a lot of handsets.
With a 1080 x 2520 OLED display it’s certainly got a great screen though, and the Sony Xperia 10 IV also has a triple-lens camera, a 5,000mAh battery, and a mid-range Snapdragon 695 chipset – plus 5G support.
It’s water resistant too, and includes 128GB of storage and 6GB of RAM, so it’s got a strong assortment of mid-range specs.
5.81-inch display and 144 x 69.4 x 8.2mm
In terms of screen size, the Google Pixel 4a is towards the upper end of what can be considered compact – though it’s still smaller than most smartphone displays. But the overall dimensions are actually more compact than a lot of phones with smaller screens. As such, it’s a worthy inclusion in this list, not least because it’s also an excellent handset.
The Google Pixel 4a is one of Google’s latest mid-range Pixels, delivering many of the things we like about the company’s flagship phones at a lower price.
It has a sharp 1080 x 2340 5.81-inch OLED display, a flagship quality (albeit single lens) 12.2MP rear camera, mid-range power (from a Snapdragon 730G chipset and 6GB of RAM), and a crisp, clean take on Android 11 – with the likelihood of a day one software update to Android 12 when that lands in late 2021.
Note that there’s also a Pixel 4a 5G, but this is actually quite a different phone, with a bigger screen, so if you want a compact, opt for the 4G model. There’s a Pixel 5a too, but that’s also bigger and isn’t available in the UK.
5.8-inch display and 142.2 x 69.9 x 7.9mm
The Samsung Galaxy S10e is getting on a bit but it’s still a mid-range handset. It’s compact too with its 5.8-inch screen, which thanks to minimal bezels is physically smaller than you might expect.
It’s the baby of the S10 range, but it still has an awful lot going for it, including a brilliant 1080 x 2280 Dynamic AMOLED screen with support for HDR10+, water resistance, a high-end Exynos 9820 chipset and upwards of 6GB of RAM.
The Samsung Galaxy S10e also has a dual-lens camera, and with one of those lenses being variable aperture it’s very versatile.
You also get fast charging, wireless charging, and even the ability to wirelessly charge other devices with it.
5.7-inch display and 147.1 x 68.8 x 8.2mm
The Google Pixel 4 has a bigger screen than the Pixel 3 at 5.7 inches, but the overall dimensions are only negligibly larger, and this is a better phone in most ways.
Perhaps most significantly it adds a second rear camera, with a 16MP telephoto lens joining the 12.2MP main one. It’s a combination that allows for superb shots, even if you just point and shoot, showing that lots of lenses isn’t necessary for great smartphone photography.
The Google Pixel 4 also packs in a fairly high-end Snapdragon 855 chipset, while its 1080 x 2280 screen has a 90Hz refresh rate, making interactions smoother than on many handsets. And as with other Pixels it packs pure Android and will be first in line for updates.
It’s no longer the newest Pixel model, but it display is slightly smaller than the one on the Pixel 5 found elsewhere on this list, while the Pixel 6 is too big for inclusion.
5.8-inch display and 147.7 x 68.7 x 8.5mm
The Galaxy S9 launched as a true flagship in 2018, and while the Galaxy S10, S20 and S21 have it beat, the S9 is still an impressive phone, but now it’s cheaper than ever, and at 5.8 inches it can just about be considered compact – especially as the bezels are quite small.
This has a 5.8-inch 1440 x 2960 screen and as well as being sharp it’s just all-round one of the best you’ll find on a phone, even in 2020.
The Galaxy S9 also has a reasonably powerful Exynos 9810 chipset, 4GB of RAM, water resistance, and a 12MP variable aperture camera, giving you far more versatility than you’d expect from a single lens.
You also get stereo speakers, a premium build, lots of storage (plus a microSD card slot), and both a fingerprint scanner and an iris scanner.
You might expect compact phones to be cheap, but in fact most of the cheapest phones actually have quite big screens these days. As such your options in this category are limited, but the following is a strong choice.
5.45-inch display and 148 x 71.8 x 9.3mm
The Nokia C01 Plus isn’t an overly exciting smartphone, but it’s certainly a very cheap one, and with a 5.45-inch screen it’s also a fairly compact one.
Its specs include a 720 x 1440 display, a basic octa-core Unisoc SC9863A chipset, 1GB of RAM, a 5MP main camera, a 5MP front-facing one, and a 3,000mAh battery.
A powerhouse this is not, but then at well under £100 it doesn’t need to be. And that also makes its plastic body very forgivable.
The Nokia C01 Plus is a great option then if you want something palm and pocket-friendly that does the basics but not much more. This also makes it a good choice as a secondary or festival phone.
The Unihertz Atom is probably the smallest smartphone that’s easy to get hold of in the UK at the time of writing. It’s available from Amazon and other sites, and with a 2.45-inch screen its display is little more than half the size of the smallest other phone on this list.
And as the Unihertz Atom runs Android it’s undeniably a smartphone. Though unless you simply want the smallest phone possible it’s probably not the one to buy, as the specs aren’t up to much.
It has a 2GHz octa-core processor, 4GB of RAM, 64GB of storage, a 16MP rear camera, an 8MP front-facing one, and a 2,000mAh battery. That’s probably about all you can expect in a phone of this size, but for a more capable smartphone, consider one of the options above.
As you can see, there’s a wide range of compact smartphones available, sporting different prices, strengths, and operating systems. While above they’re listed in terms of price bracket and quality, below you’ll find them in approximate ascending order of overall size, followed by a rundown from worst to best.

In terms of how good they are, the Nokia C01 Plus is the worst (not including the Unihertz), but it’s very cheap and performs accordingly.
Then comes the Google Pixel 4a, which is a solid mid-ranger, and the Samsung Galaxy S9, which is an aging flagship, now just about packing a mid-range price. They’re followed by the Samsung Galaxy S10e and the Google Pixel 4, and then the Sony Xperia 10 IV. Then we’re into iPhone territory with the iPhone SE 3rd Gen, followed by the iPhone 12 Mini as our top mid-range pick.
Then for the overall top four it’s the Asus Zenfone 8 in fourth, the iPhone 11 Pro in third, the Samsung Galaxy Z Flip 3 5G in second, and the iPhone 13 Mini in first – as it’s both high-end and tiny.
Any of these phones would serve you well if you’re after a small screen though, it all just depends on how much you want to spend and whether you want Android or iOS.
