The resolution of the sensing layer on a graphics tablet determines how detailed the tablet can capture the movement of the pen or stylus on its surface. It is measured in lpi (lines per inch), which is the number of lines the tablet can detect per inch. Higher resolution values mean greater accuracy and finer detail is recorded. In practice, it is common to see values such as 2540 lpi and 5080 lpi, with 2540 lpi being suitable for general graphics work and 5080 lpi offering a higher level of detail and accuracy for professional use, such as creating highly detailed illustrations or designs. The higher resolution is particularly useful for artists who need to capture fine strokes and details with high fidelity.
