A couple of common questions we receive are, What Is Lines Per Inch? And what does the LPI specification mean when looking at drawing tablets? Before we discuss how this specification can influence your decision when choosing a graphics tablet, we’ll take some time to understand what this term means when working with print and digital media.
Lines per inch (LPI) is a term that is commonly used in the printing industry to describe the resolution of an image. Alternatively, you can think of it as a measure of how many dots or lines can be printed in a given area or the number of lines that can be printed in one inch of space. The higher the LPI, the more lines can be printed, resulting in a higher-quality image.
This is important because the LPI determines the level of detail that can be captured in an image. For example, if you are printing a photograph, a higher LPI will result in a sharper, more detailed image. LPI is an important factor in determining the quality of printed material, as it affects the clarity and sharpness of text and graphics.
What Is Lines Per Inch in Context
Understanding LPI is crucial for achieving high-quality printed material, so we’ll take some time to differentiate LPI with other terms that commonly used terms.
Practical Applications of LPI
LPI in Print Media
LPI is an essential factor in determining the quality of print media. The higher the LPI, the better the detail and clarity of the printed image. When printing on newsprint paper, a lower LPI of around 85-100 is recommended to avoid ink bleeding and achieve a higher resolution. On the other hand, commercial magazines and printed materials often use a higher LPI of 150-300 to produce sharper images and more detailed halftone dots.
LPI in Graphics Tablets
A graphics tablet can be used to create detailed halftones and achieve a higher LPI, so if you’re looking for a new graphics tablet, be sure to take the LPI into account. When reviewing the LPI specification for a graphics tablet, it is important to understand that the LPI is a measurement of how many distinct lines can be drawn in one inch.
In the context of drawing tablets, a higher LPI generally means greater precision and detail in your drawings. The higher the LPI, the more lines you can draw per inch. A couple of tablets that we like for beginners with higher LPI are the XP-Pen Artist 12 Pro and the Huion Inspiroy H1060P. Both offer an LPI of 5050.
You may only use your drawing tablet for digital art, but if preparing an image for print, it is important to consider the LPI and dot gain to ensure the final product meets the desired quality standards.

LPI in Digital Media
In digital media, LPI is often referred to as “pixels per inch” (PPI) or “samples per inch” (SPI). It is a measure of the spatial resolution of an image. Higher LPI or PPI results in a higher pixel density, which means more detail and sharpness in the image. For instance, a 300 PPI image is considered high resolution and is suitable for printing on coated paper.
LPI is also important when working with vector graphics and file formats. When creating a graphic design for print or digital media, it is essential to consider the physical size and pixel count of the image to ensure it meets the required LPI or PPI for the output device.
LPI in Graphic Design
In graphic design, LPI is used to determine the halftone grid and dot gain for printing resolution. The halftone dots are created by varying the size and spacing of the ink dots on the paper. The dot gain refers to the amount of ink that spreads out from the dot, which can affect the color and sharpness of the image.
In summary, LPI is a crucial factor in determining the quality of print and digital media. It is essential to consider LPI when working with print media, digital images, and graphic design. It is also an important specification to consider when choosing a new drawing tablet.

We hope you found this guide helpful, whether you’re looking to understand what lines per inch means in graphic design or you want to better understand the LPI specification before purchasing a new drawing tablet.
This is a fantastic article on lines per inch! I was always wondering what LPI meant every time I used applications like Photoshop and was about to print something. Having read this article, I do have a few questions, though. Is there any reason for people to opt for lower LPI in digital media and graphic tablet work? It seems like we should use the highest possible LPI at all times for the best image quality.
You are correct — LPI is very important. The reason why you might elect not to have a higher LPI is if you primarily want to use your tablet as an ergonomic device. There are users who elect to use one instead of a mouse, in which case LPI is not really a factor.
The other thing to keep in mind is, as a general rule, the higher the LPI, the more expensive the drawing tablet. There are some exceptions, like with the Huion Inspiroy H1060P. For its price point, it offers a 5080 LPI resolution, which is comparable to other tablets in a much higher price range. I hope that helps!
