To make your Popup responsive you should do the following:

Select the Custom mode in the Dimensions section of your Popup settings.

Set Width and Height in pixels (px) and Max width and Max height in percentages (%).

When the screen is too wide, Max width option will work and it will prevent showing a too large Popup.

Width: 640px

Height: 480px

Max width: 80%

Max height: 90%

Min width: 300 (px)

Min height: 100 (px)
