How do I fit an image to the size of my computer screen?

Hi everyone!

I want to present an image on my screen, but although it has the same pixel dimensions as my MacBook Air 13 computer screen (= 2560 x 1600), it seems to zoom in when I run the experiment. Anyone have an idea how I can fix the size of the image to fit my screen, or just how to change the size of an image in general in psychopy?

Thank you so much for your help in advance :slight_smile:

PsychoPy uses a number of different units for position and size.

norm is good for text. Your screen is 2x2 norm units.
height is good for online. Your screen is 1 height unit tall and 1.6 units wide. The width depends on your aspect ratio.
pix can be simple to use locally when you donโ€™t want to calculate the aspect ratios of your images.
cm only works offline and needs you to tell PsychoPy the dimensions of your monitor.
