Handling image resolution in InDesign and PPT

Image resolution determines the quality and detail an image will have. The higher the image resolution, the more detail an image will be able to produce. If images are enlarged and look blurry and/or pixelated, it could be that your image resolution is low. 

What’s the right resolution for my image?

The right resolution will depend on the media in which the image will be used. If the image will be used for the web, resolution must be at minimum 72 DPI. If the image will be used for print, resolution must be at least 300 DPI.

How to check your image resolution for Windows users: 

  1. Select the image 
  2. Right click on the image
  3. From the menu, select Properties
  4. A window will pop up, click on the Details tab
  5. Review the sizing measurements as well as resolution

How to check your image resolution for Mac users:

  1. Search image in the Finder
  2. Right click and select Get Info from the menu
  3. Under More Info, review the dimensions of the image

How to check your image resolution in InDesign

  1. Place the image and select it
  2. From the menu bar, click on Window
  3. Select Info from the menu
  4. The Info panel will appear, verify the Effective PPI
