Image Resolution Converter

Image resolution is a crucial aspect when it comes to digital imagery and printing. It determines the level of detail and clarity in an image. Understanding image resolution and having a reliable image resolution converter tool can greatly assist in optimizing image quality across various mediums. In this article, we will delve into the definitions of key image resolution units and provide a comprehensive guide to their conversion.

What is Image Resolution?

Image resolution refers to the amount of detail present in a digital image and is typically measured in terms of the number of pixels per unit of length. It determines the sharpness and clarity of an image. Higher resolutions have more pixels, resulting in finer detail, while lower resolutions have fewer pixels, leading to a loss in detail.

Units of Image Resolution

  • Dot per meter (dpm): Dots per meter is a unit of image resolution that measures the number of dots or pixels per linear meter. It is commonly used in the printing industry to determine the print quality. The higher the dpm value, the finer the detail in the printed image.
    Conversion Factor: 1 dpm = 0.001 dpmm = 0.0254 dpi = 0.0254 ppi

  • Dot per millimeter (dpmm): Dots per millimeter is a unit of image resolution that measures the number of dots or pixels per linear millimeter. It is often used in industrial printing and high-resolution imaging applications.
    Conversion Factor: 1 dpmm = 1000 dpm = 25.4 dpi = 25.4 ppi

  • Dot per inch (dpi): Dots per inch is a common unit of image resolution used in both digital and print media. It indicates the number of dots or pixels per linear inch. Higher dpi values result in finer details and smoother images.
    Conversion Factor: 1 dpi = 39.37 dpm = 0.03937 dpmm = 1 ppi

  • Pixel per inch (ppi): Pixels per inch is a unit of image resolution that denotes the number of pixels per linear inch. It is equivalent to dots per inch and is primarily used in digital imaging and display devices such as computer monitors, smartphones, and tablets. Higher ppi values indicate greater image detail and sharpness.
    Conversion Factor: 1 ppi = 39.37 dpm = 0.03937 dpmm = 1 dpi
