Getting Coordinates in Percentage

The hotpoint shortcode requires you to provide coordinates for the point in percentage, not pixels. This ensures that your points are placed properly at any resolution or size – from small phone displays to large desktop monitors.

Using Adobe Photoshop it’s relatively easy to get percentage coordinates for your image.

Step 1: Get the Image Resolution

Open your image in Photoshop and then go to Image > Image Size. On a scrap piece of paper, write down the width and height of your image.

Step 2: Get the Coordinate in Pixels

Choose the ruler tool. Click and drag on your image starting at the place you want to put your point. Copy down the X and Y coordinates for each hotpoint you’d like to create.

Step 3: Calculate Percentages

Now that you have the width, height, x, and y values for your image, you can easily calculate the left and top values using the formulae:

  • left = 100 × (x/width)
  • top = 100 × (y/height)
