Tablet Buyer's Guide: what size tablet should I buy?

What size tablet should I buy?

Tablets are, with one or two exceptions, smaller and lighter than laptops, which is why they're so popular. They predominantly come in three screen sizes: 7-inch, around 8-inch or 10-inch. Each has its own strengths and weaknesses, and fundamentally changes the way you use your tablet.

To help you choose, think about the following things:

1. How often will the tablet leave the house?
Will you use it mostly at home on the sofa or in bed, or do you plan to take it everywhere and use it when commuting?

2. What's the primary thing you want to do?
Each size is good for the basics like web browsing. It's when you think about other tasks, such as reading, videos and playing games, that the differences are more pronounced.

3. How much are you willing to spend?
The bigger the tablet, the more expensive it'll be. If you only have a little to spend, you may have to go for a smaller, 7-inch tablet.

7-inch Tablets: Pros and Cons

In a nutshell:
  • Very portable and comfortable to hold in one hand
  • Cheaper than 10-inch versions – some cost £100 or less
  • Best for reading books and commuting
  • Small screen makes browsing the Internet a bit trickier
  • Not the best for digital magazines and newspapers
Most of the 7-inch tablets available run Android. There are some smaller Windows tablets, but they're relatively new and not all of them are on sale yet.

The advantages of 7-inch tablets are primarily their portability. They’re much lighter than bigger-screened tablets, but still come with great displays, plenty of storage and fast processors. They’re also cheap – you can get a decent 7-inch tablet for around £120, but they do go up to £600 for a fully kitted-out iPad mini 3

7-inch tablets are great for using on the go, whether on a commute or holidaying on a sunny beach. The high-quality screens and long battery life mean they can even substitute as eBook readers. Because the screen is smaller, you may find it a little difficult to navigate some websites, particularly if your eyesight isn’t 20/20. They’re also not the best for watching movies or TV programs, again because of the screen size, but also because the speakers tend to be quite weak and tinny. Headphones solve that issue, though. 

Finally you’ll struggle to use a 7-inch tablet well for productivity – writing lengthy emails, editing spreadsheets and suchlike. While you can get keyboard docks for some of them, the screen and keyboard size means that they’re not comfortable for writing over long periods of time.

8-inch(ish) Tablets: Pros and Cons

These have grown in popularity since the release of the 7.8-inch iPad mini a few years ago. There are now a number of good 8-inch Android tablets on the market, such as the Nvidia Shield Tablet or the 8.9-inch Nexus 9 and Kindle Fire HDX 8.9 (2014).

Some like the iPad mini and Nexus 9 opt for a squarer 4:3 aspect ratio for their screens, just like old CRT tellies used to have. We think this is a better shape for a tablet. It makes browsing the web and playing games a better experience, but you do end up getting bigger black bars at the top and bottom of the screen when you're watching movies when compared to narrower tablets.

8-inch tablets cover a good middle ground. They're better for browsing the web, reading ebooks and watching movies than a 7-inch tablet, yet they manage to retain much of their portability. The downside? They're a fair bit more expensive than some of the best 7-inch Android tablets on the market.

A few words of advice if you're thinking of buying an iPad mini: go for the iPad mini 2 32GB option rather than the iPad mini 3. The tablets are almost identical, but the iPad mini 2 is a lot cheaper.

10-inch Tablets: Pros and Cons

In a nutshell:
  • Large screen is good for TV, video and the visually impaired
  • Best for reading newspapers and magazines
  • Better for productivity, especially when paired with a keyboard
  • More expensive than smaller tablets
  • Heavier and therefore less portable
10-inch tablets are a fair bit heavier and more difficult to handle than 7-inch ones, but are also more versatile in terms of productivity and enjoying TV, online videos, newspapers and magazines. 

The high-resolution 10-inch screens are great for watching movies, and the extra space means that better speakers can be included. You can happily watch programs on one with another person. Digital magazines come to life on the bigger screen and you can view high-resolution image galleries in all their glory, and interact with articles in exciting new ways. 

Some 10-inch tablets also come with keyboard docks that make them a useful writing and productivity tool. Great examples of these are the Windows-running Asus Transformer Book T100 and the Microsoft Surface Pro 3. Apple doesn't make a keyboard for the iPad Air 2, but there are many third-party companies that do, which means you can make it work like a laptop, too.

Other things to consider

What screen resolution is best? Does it matter?
The screen resolution of the tablet makes a big difference to how clear it is and really affects your experience. Any 7-inch tablet with a 'Full HD' screen should be great, but some tablets are brighter and are less reflective than others, which means they’re better suited to using outside on sunny days. It's worth trying this out in the store by tilting the screen towards the overhead lights.

10-inch tablets can have much higher-resolution displays. The screens of the Nexus 9 and iPad Air 2 are particularly strong and provide an excellent tablet experience with razor-sharp text. The Air 2 has a fantastic anti-reflective layer that makes it better than any other tablet to use outdoors on sunny days.

By contrast, similarly priced laptops tend to have much lower-resolution displays that can look dull and grainy. 

What is 'screen ratio' and what difference does it make?
Screen ratio simply refers to the 'shape' of the screen. For example, most modern TVs and laptops are 16:9 (aka widescreen), while old CRT TVs were 4:3.

Most Android tablets favour a 16:9 or 16:10 aspect ratio, so they’re quite tall and thin. This means the black bars that appear when watching widescreen movies are minimised. On 7-inch tablets this ratio makes tablets feel more like books when held in portrait, so they're more comfortable for reading. On 10-inch tablets, however, this can lead to them feeling too tall and unwieldy, while it's not the ideal shape for web pages, newspapers and magazines

iPads (and recently some Android tablets) have a 4:3 aspect ratio. The big black bars you may get when watching movies are offset by the benefit of a squarer screen while browsing the Internet and using apps or playing games. It's a shape that works best for newspapers and magazines, too.

Is it worth buying a tablet with 3G/4G?
Most tablets come in two versions: one with Wi-Fi only and another with Wi-Fi and 4G and/or 3G. Wi-Fi-only means that you’ll need a Wi-Fi connection to use the Internet, whether at home or in a café. 

4G tablets allow you to insert a SIM card so that you can use a mobile network to have Internet access wherever you can get a signal, just like you do with a mobile phone. 

You’ll need a subscription, though, again in the same way as your phone. 4G used to be pricey, but you can now get it for £15 per month on EE for 2GB of data. That should be enough, unless you often use your tablet to stream TV or movies on the move. 

All 4G tablets can also use a 3G connection. 3G is an older technology and therefore slower than 4G. It's cheaper, though – around £7.50 for 1GB every 30 days on Three or £10 on O2. 

One thing we do keep hearing from tablet owners is that they wish they’d bought one with mobile Internet rather than Wi-Fi only. If you commute you should really consider a 3G or 4G tablet with a connection.

How much storage do I need?
If you like to have a lot of music or movies on your tablet, you'll need a lot of storage. Storage is measured in gigabytes (GB). 32GB is ample for most users, but some tablets come with the option of adding extra capacity via a microSD card. These are bought separately and are relatively cheap.

Only some Android and Windows tablets come with a microSD slot
you don't get that option on iPads, so you're stuck with what you chose initially. If you get a tablet with only limited storage, say 8GB, check to make sure it accepts microSD cards. If it doesn't, don't buy it.

How much do I need to spend and how can I save money?

Tesco Hudl 2
The 7-inch Tesco Hudl 2 is a great tablet that can cost as little as £65 with vouchers

Finally, one of the biggest things that will define which tablet you should buy is your budget. Generally 7-inch tablets are much cheaper than 10-inch ones and iPads are more expensive than Android tablets. 

One thing you should be very wary of is 'bargains'. Beware the 7-inch tablet that sounds good on paper but costs only £80, or the 10-inch one that costs £150. These are almost always poorly made using cheap materials and provide a shockingly bad experience. A classic example of this is the Argos MyTablet. Steer well clear.

One exception, however, is
the Tesco Hudl 2 tablet pictured above. It costs £129 as standard, but can be bought for as little as £65 with Tesco Clubcard vouchers, which is frankly ludicrous. It's a good tablet that's well worth considering if you're on a tight budget. 

Shoddy tablet makers usually don’t want their product reviewed, so make sure you check TrustedReviews' tablet reviews if you want to know about a tablet we’ve not recommended in our list of best tablets. If we haven’t reviewed it, it's likely not worth owning. 

Now it’s time to find out which tablets you should look to buy this Christmas.
