What's best - 7 inches or 10?

Bigger isn't always better. (That's what she said! Etc.)

When I got my first 7-inch tablet computer, I was delighted. It made my little smartphone seem positively dwarven. Look at all this SPACE! Look at all the APPS! I scrolled and surfed and gamed and was happy. Then I saw a deal on a ten-inch one, and I had to have it. Surely it would be even better than the smaller one?

Well, yes and no.

It was certainly amazing to watch Game of Thrones and The Walking Dead on it. And it was great that it displayed much more of The Guardian or NFL.com. It was just... kinda awkward holding it for a while, and obviously it was much heavier than my little 7-inch one.

A strange thing happened - I started using the 7-inch one more, since it was easy to potter around the apartment while holding it. And I used the 10-inch one when I was sitting down or wanted to be productive.

I guess what I'm trying to say is: think about what you're going to use your tablet for before deciding how big the screen should be. If watching movies is high on your list - think big. There are great tablets ranging from 10 inches to ones the size of coffee tables. If you want something to hold in one hand while you read the news on a Sunday, sipping your coffee and walking around the garden, you'll probably be happier with a 7-inch device.

Have you decided? Okay, good. Now follow one of these links to compare tech specs for tablets in that size:

How Big is a 7 Inch Tablet Screen?

7 inches is 17.78 centimetres.

Robert Brault (poet/author) said "The average pencil is 7 inches long, with just a half-inch eraser - in case you thought optimism was dead."

A credit card (or business card) is 3.5 inches wide, so you can place two together to imagine the height of a 7-inch tablet.

A dollar bill is 6 inches - you can use one to estimate a lot of things! (Tip - fold one into thirds, then half, and each crease will be one inch. You're welcome.)

More About Tablet Screens

Touch screen technology has brought about a revolution in the new-age and broadcast media industries and is now widely adopted by Television, Computer, Mobile Phones and Camera manufacturers. Tablet computers are among the most visible manifestations of this technology and are seen as a possible replacement for regular desktops and laptops in the foreseeable future.

Display resolution

Screen resolutions vary according to the manufacturer and the price range in which the tablet is sold. From the QXGA resolution on the New IPad to the WVGA resolution that is found in the most basic models, there is a wide choice available for the consumer depending on his or her personal needs.

Typically, the screen resolution can be categorized as follows:

  • QXGA: 2048 x 1536
  • WXGA: 1366 x 768 or 1280 x 800
  • XGA: 1024 x 768
  • WSVGA: 1024 x 600
  • WVGA: 800 x 600

Tablets of smaller sizes such as the 7 inch can do well with a lower resolution screen. Higher screen resolution becomes relevant as the tablet size increases.

Screen Coating, Brightness and Protection

Since tablets are highly portable devices, they are widely used indoors and outdoors. While screen brightness is not really an issue when used indoors, these tablets can become highly reflective in outdoor daylight conditions and therefore needs the screen brightness to offset the ambient brightness. Most manufacturers have overcome the problem by using a coating that prevents glare while also protecting the glass from scratches and dirt. If your tablet display is protected using a toughened glass such as Gorilla Glass, the chances of screen cracking due to the tablet accidentally falling on the ground is minimized.

Screen Viewing Angles

While this may not be a major concern if you are using the tablet as a hand held device, screen dimming and colour change can be an irritant if you are placing the tablet on a stand or keeping it on a table for people around you to see. This problem is normally found in LCD displays made using TN technology. Colours like red, blue or green become darker and the screen becomes dimmer as you move away from the centre of the screen. Make sure that you get to test this out on a demo piece at the retailer before you choose your tablet. Most modern tablets do not use the TN technology in their LCD display.

Screen Technology

There are 2 prominent TFT (Thin Film Transistor) LCD Screen technologies available today.

In Plane Switching technology or IPS was developed in Japan in response to the viewing angle problems caused by LCDs based on twisted nematic display technology. IPS LCD screens have almost no viewing angle colour changes.

Plain Line Switching or PLS is a relatively new LCD technology and was developed by Samsung in Korea and has lower manufacturing costs as compared to other LCD technologies. With improved image quality, viewing angles and screen brightness, PLS is expected to address several of the issues faced by tablet manufacturers.
