Screen size has always been important, since the first handheld device was released on the market. The most important aspect to keep in mind when deciding on a screen size, is what the main usage of the device will be. It is also important to determine who will be using the tablet as smaller tablet sizes are ideal for kids.
If the device is required for mix use (e.g. Business and Pleasure) and will need to be carried around quite a lot, it is preferable to go for 7 inch tablet as this will comfortably fit into a satchel or handbag. It will also not be too heavy, which overall will make it comfortable to use.
From a gaming perspective, I feel that a 7 inch tablet is also more ideal as the lighter, smaller device is easier to handle during lengthy game play periods.
If the device is for a small child (younger than 10 years), it is advisable to go for a 7 inch tablet.
If you like to read magazines or watch movies on your tablet, I would propose that you go for a 10.1 inch tablet rather, as the bigger screen will enhance both experiences.
Bigger tablets are also advisable if you are going to use an editor on it.
Things to keep in mind about the bigger tablets are the following:
- They are heavier.
- The are more difficult to carry around as they don't fit into traditional bags (handbags etc.)
- They are better for watching movies and reading bigger documents including magazines.
- They are also better to use if you are going to use an editor or a spreadsheet tool.
There are many tablet sizes between 7 inch and 10.1 inch, which can make it sometimes make it easier to decide.
The golden rule to stick is to always base your decision on size on the purpose of the device in your life!
