Hello. I am quite newbie for overall programming, so I’m unfamiliar with some terms used in building some experiments.
I set the font size (that is written as ‘letter height’ in the builder) as 0.07, but I am not sure what this value means.
Since I am familiar with point units, I wonder if I can change this 0.07 value into point value.
Anyone can help? It would be really helpful.
Hi,
you can change the unit for the letter height. The default is “unit”, with 1 unit being the height of your screen. This also relates to the position coordinates: (0, 0) is exactly in the middle of the screen. So 0.07 is slighlty less than 1/10 of your screen size. You can change the unit to cm or pixel if you want.

Answering more as a typography nerd than as a PsychoPy dev here…
“point” units in typography usually go off the Caxton scale I believe, so you can figure out the equivalent in PsychoPy by setting your units to “cm” and using the corresponding values from the left side of this handy ruler which I definitely didn’t spend my real life money buying just because I think it’s cool:
Thanks for your reply.
I think I understood.
Thanks for your explanation.
I think I have to study more!
