   Hi @kvanderwijst, thanks for the encouraging words and for giving Kaleido a try!

   I can confirm what you're seeing and this is definitely an oversight. Until we get a fix out, you can work around this by setting the default width/height to None like this:

   import plotly.io as pio
   pio.kaleido.scope.default_width = None
   pio.kaleido.scope.default_height = None

   ---

   Technical details:

   The culprits are these lines:

   https://github.com/plotly/Kaleido/blob/798fa989c594d370b4b2956a6579fe9c5e74dfae/repos/kaleido/py/kaleido/scopes/plotly.py#L71-L72

   For width, we should check the figure's layout.width and layout.template.layout.width properties before falling back to self.default_width. Same for height.

   In the meantime, this can be worked around this by setting the default width/height to None like this:

   import plotly.io as pio
   pio.kaleido.scope.default_width = None
   pio.kaleido.scope.default_height = None

   In this case, the figure's width and height will be used if they are available, otherwise the are chosen using the defaults defined in the JavaScript layer here:

   https://github.com/plotly/Kaleido/blob/798fa989c594d370b4b2956a6579fe9c5e74dfae/repos/kaleido/js/src/plotly/constants.js#L22-L27

   Note: This issue only affects the Python Plotly scope, other wrappers of the Kaleido C++ core do not have this problem.

   Interestingly, Orca also ignores the built-in height and width when using it with fig.show("png") for example. Would be great to get a fix for both.

   (both renderers and writers I mean... fixing Orca in post-4.9 doesn't make much sense)

   This is probably a change we'll need to make in the plotly.py renderer code since they also have default width/height logic.

   OK, let's pursue here: plotly/plotly.py#2651
