A graphics tablet (or digitizing tablet, graphics pads or drawing tablet) is a small electronic input device. Like a mouse or keyboard, it allows a user to interface with his or her computer. A tablet consists of a flat surface and a stylus, to be used like a virtual pen and piece of paper. Your computer's cursor reflects any movements made by the stylus on the tablet, allowing you to point, click, write and draw on your computer.

How do I go about buying a graphics tablet?

Buying a graphics tablet can be a little overwhelming at first, but here are the most important features to consider before purchasing anything: the tablet's price and size (these two go hand-in-hand; the larger the input area on a tablet, the steeper the price), interface (how the tablet connects to your computer), pressure sensitivity (how sensitive the tablet is to reading differing pressure levels from the stylus) and any accessories or peripherals (note any included stylus, mice, connection cables) .

Before you go out to any store, decide the price range that you're willing to pay. Graphics tablets vary wildly in their prices, so it's a good idea to decide beforehand what your price limit is. Most of the more expensive models are geared toward the professional user, so they are generally larger and have more advanced features. There exists a large number of inexpensive models that offer a more practical option for the novice user or hobbyist.

The size of a graphic tablet refers to the size of the input surface area, not necessarily the size of the actual physical tablet. Standard sizes include 4"x5", 6"x8" and 9"x12". It is important to note that the prices increase dramatically with the size, so it helps to keep in mind the price limit that you've set for yourself.

Most graphics tablets communicate with a USB interface and do not require a separate power source. The other option would be a serial interface, which necessitate a separate power source and an open serial port on your computer. It's important to weigh the different interface options to decide which is the right setup for you and your computing needs.

Graphics tablets utilize pressure sensitivity to recognize and respond to the movements of the stylus pen. Different graphics tablets have different pressure sensitivities, with standard pressure sensitivities being 256, 512 or 1024. The higher the number, the more sensitive the tablet is to pressure changes of the stylus. Of course, it should be noted that an increase in sensitivity usually equates to an analogous increase in price as well.

Lastly, think about any included accessories the tablet offers, the most important being the stylus. If your tablet includes a stylus you should try it out- make sure it fits and feels comfortable in your hand. Note how it is attached to the tablet, if at all. Does it require any batteries or power source? Does the tablet come with any other accessories (like a mouse or a stylus stand)?

You should have a little better idea about shopping for a graphics tablet now, but it is ultimately a personal decision to make. Try to think about what you want out of your future tablet before purchasing- Will you need it to be portable? Are you looking to use it for work? How much are you willing to spend? By answering these questions beforehand, it makes finding and purchasing the perfect tablet a little less daunting. So good luck and happy shopping!
