Format
The paper size that corresponds to the size of the tablet's active surface.
This parameter is specified only for traditional tablets and smart-notebooks (see "Type"). At the same time, the specific size of the device does not always strictly correspond to the specified format. For example, an
A4 tablet can be either a little larger or a little smaller than a standard landscape sheet of 210x297 mm. Nevertheless, according to the specified format, one can easily estimate the dimensions of the tablet as a whole and its general “weight category”.
Nowadays, on the market you can find devices in formats from A3 to A7, and the most popular options are the A4 mentioned above, as well as
A5(148x210 mm) and
A6(105x148 mm). In general, larger tablets are easier to use, but also more expensive.
Workspace
The exact size of the active area of a tablet (or screen in a graphic display) in width and height. In general, it is more of a reference than a practically significant parameter: when choosing a traditional graphics tablet, there is often enough information about the format (see above), and for displays, primarily the diagonal (see above) and aspect ratio (see below) are of practical importance . However, the exact dimensions can also be useful in fact: for example, you can determine the aspect ratio from them (for classic tablets, this parameter is often not indicated).
Control keys
The number of control keys provided in the design of the tablet.
Each of these keys is responsible for a specific function, while the set of these functions can be configured: in some models they can be selected manually, in others the functionality of the keys changes automatically, depending on the currently active application. Anyway, additional keys allow the user to perform various actions without looking up from the tablet — this can be very convenient in the midst of the work process, when you don’t want to change the pen to the mouse again or reach for the keyboard. And the more control keys — so, respectively, more additional actions can be performed using the tablet. On the other hand, with relatively simple tasks, the abundance of additional buttons can hinder and confuse the user rather than help.
The most modest modern tablets provide
up to 5 control keys ; the most popular option is
from 6 to 10 keys, and in advanced models this number can reach
15 or even
more.
Pen model
The model of the pen that comes with the device. Allows you to understand which one is used and learn more fully its full characteristics. In this case, in the case of a replacement, you will already be aware of which accessory is needed for the purchase. However, nothing prevents you from replacing the existing one with a more advanced one, of course, if the graphics tablet itself allows you to work with a different pen model.
Max. reading height
The height within which pen movements above the working surface are recorded by the tablet electronics even in the absence of direct contact.
Many tablets allow you to work in a "non-contact" way — without directly touching the stylus to the work surface. Thanks to this, it is possible, for example, with a raised pen to bring the cursor in the graphics editor to the desired point and turn on the drawing mode by touching the tablet with the stylus. And the greater the maximum reading height, the more convenient it is to use this mode, the less demanding the tablet is for the accuracy of movements. In many modern models, this parameter exceeds 10 mm.
Pressure levels
The number of pressure levels supported by the pen.
The more levels of pressure, the more accurately the pen tracks the force of pressure and the closer the drawing is to the drawing made by real tools like a pencil. The minimum value for a modern tablet is
512 levels, an indicator of
1024 levels is considered relatively small,
2048 is considered average, and in some models
4096 and even
8192 levels are found. At the same time, it is worth noting that the difference between pens with different accuracy becomes noticeable mainly on the thinnest strokes and on lines with a thickness that changes along the stylus; so numerous levels, even a professional artist is not always required. For this reason, this parameter has practically nothing to do with the general class of the device: for example, there are low-cost models on the market with 8192 levels, and professional solutions with only 1024.
Resolution
The resolution of the graphics tablet's working area, expressed in lines per inch (lpi). The parameter includes the density of sensors on the tactile surface of the device per inch. It is these sensors that recognize the signal upon contact with the pen. The higher the resolution, the more accurately and in detail the movements of the pen across the working area of the tablet are transferred. This ensures the creation of objects with a high degree of detail.
The simplest devices are characterized by an indicator of
2540 lpi. The “golden mean” is
4000 lpi. And in professional graphics tablets the
a resolution of 5080 lpi can be found. Moreover, it is important to take into account that higher accuracy significantly affects the cost of the device.
