Group: Forum Members Posts: 45, Visits: 249	Hi there, I have made a dot-probe where pictures appear on the left and right side of the screen. At the moment the left pic is positioned (30%, 50%) and the right pic (70%, 50%). However, this task will be completed by participants on different sized computers and I want to make sure that the pictures will always be equal distance apart - for example 10cm. What is the best way to achieve this? Thanks, Charlotte

You can specify pixels (px), centimeters (cm) or millimeters (mm). If you want to ensure an accurate distance of 10cm, you need to include a calibration procedure in your script. Pixels (which as what displays deal with) have no fixed relationship to physical dimensions (mm, cm): https://www.millisecond.com/forums/Topic14608.aspx
