The Z axis is usually used for depth, so it’s going to be perpendicular to whatever your frame of reference (i.e. projection plane) is.
If it’s upright in space, like a computer screen, the Z axis will be horizontal. If it’s a sheet of paper on a desk, then yes, I suppose it could be argued to be vertical instead.
Isn’t the Z axis vertical?
Not in bistromath.
Indeed, a common mistake for newcomers to the field.
It’s typically vertical, but you can name your variables however you want.

in lots of 3D software Z is horizontal
All the 3D printer software, Z is vertical. But I only used a couple so I am not an expert.
🤔
Yup.
Horizontal going into the screen right? The depth axis, if you will.
I’ve definitely seen Z as the forward/backward axis before
No? That would be the y axis.
