How to Measure Image Size?

Published in Image Properties 2 mins read

Measuring image size depends on what you mean by "size." It can refer to either the file size (how much storage space the image occupies) or the dimensions (width and height in pixels). Here's how to find both:

Measuring Image File Size

The file size tells you how much space the image takes up on your hard drive or storage device. It's usually measured in bytes, kilobytes (KB), megabytes (MB), or gigabytes (GB).

  • Windows:

    1. Right-click on the image file.
    2. Select "Properties."
    3. In the "General" tab, you'll find the "Size" and "Size on disk" information. "Size" refers to the actual data in the file, while "Size on disk" reflects the space it occupies after accounting for file system overhead.

  • macOS:

    1. Right-click (or control-click) on the image file.
    2. Select "Get Info."
    3. The "Size" will be displayed in the "General" section.

  • Android:

    1. Open the "Photos" app.
    2. Select the image.
    3. Tap the three dots (usually in the top right).
    4. Choose "Details" or "Info." The file size will be listed. The exact wording may vary depending on your Android version and Photos app.

Measuring Image Dimensions (Pixel Size)

The dimensions refer to the width and height of the image in pixels. This determines the visual size and resolution of the image.

  • Windows:

    1. Right-click on the image file.
    2. Select "Properties."
    3. Go to the "Details" tab.
    4. Look for the "Image" section. You'll find "Dimensions" listed as width x height (e.g., 1920 x 1080 pixels).

  • macOS:

    1. Right-click (or control-click) on the image file.
    2. Select "Get Info."
    3. The "Dimensions" will be displayed under the "More Info" section

  • Android:

    1. Open the "Photos" app.
    2. Select the image.
    3. Tap the three dots (usually in the top right).
    4. Choose "Details" or "Info." The dimensions will be listed. The exact wording may vary depending on your Android version and Photos app.

In summary, you can measure an image's size either by its file size (storage space) or its dimensions (pixel width and height), and the methods for finding this information vary slightly depending on your operating system.
