How to Resize Images video tutorial

When talking about how big specific images need to be, some of our articles say they need to be a particular aspect ratio. This is a width-to-height ratio, such as 16:9 for big-screen TVs. The slideshow requires photos to have a 5:2 aspect ratio. The Command buttons require photos to have a 16:9 aspect ratio.

You will need to crop and resize your images to fit this ratio.

Calculate Aspect Ratio

First, let's find the aspect ratio to calculate the needed height for a given width.

The following aspect ratio calculator can be used to determine what the aspect ratio should be:

  1. Navigate to https://andrew.hedges.name/experiments/aspect_ratio/

  2. Enter the aspect ratio in the W1 and H1 fields, such as 5 and 2.

  3. Enter the image width in the W2 field, such as 2000.

  4. It will automatically enter the correct height in the H2 field, in this case, 800.

  5. Crop your photo using the W2 and H2 numbers and save it.

  6. It is now ready for upload to the site.
