How to resize an image

  3. The pixel sizes are editable fields allowing you to enter the preferred height and width that you would like to change the image to. This edit option allows you to resize the pixel dimensions of an image, however you can only make the dimensions smaller.
  4. Use the Hero Banner pixel size for an internal page, let's change the pixel dimensions to 1920 x 1080 px.
  5. Leaving the Keep Aspect Ratio tick box checked, means that even though we are editing the pixel size of the image, we are preserving the relationship between the width and height of an image to help avoid it appearing stretched, squished, cropped, or image content appearing 'cut-off' which is sometimes seen as on screens as gaps or black bars. You can read more about how to find image dimensions and work out an images Aspect Ratio below.
  6. You'll see that when you select Apply, that the pixel width updates to 1620 px. This preserves to display of the image when you resize it to smaller dimensions.

What is Aspect Ratio?

Aspect ratio is the proportional relationship between the width and height of an image. The 16:9 ratio is the preferred aspect ratio for images to use when creating a Hero, Page or Gallery Banner in the CMS.

This helps to preserve the image when editing and avoid it appearing stretched, squished, cropped, or image content appearing 'cut-off' which is sometimes seen as on screens as gaps or black bars.

Within the Display settings of your computer, you may have seen an option to set the display resolution for your screen, with options for:

Common Ratios:

  • 1:1 (1080px x1080px): Square 
  • 4:3 (19200px x1440px): Standard monitors, older photos 
  • 16:9 (1920px x 1080px): Widescreen, HD video, This is also the pixel size of the Hero Banner for the Home Page 
  • 3:2 (1080px x 1920px): Instagram Stories & Reels
How to find Pixel Dimensions on an image
Right-click on an image, then select Properties from the menu. Select the Details tab and within the Inage section you will see "Dimensions for the heigh and width.
 
How to calculate the Aspect Ratio on an image
Once you have your image dimensions, divide the height by 120, and then the width by 120 to get whole numbers:
  • 1920x1080: 1920/120 = 16. 1080/120 = 9. W:H = 16:9.
