How to get matplotlib figure size

For a project, I need to know the current size (in pixels) of my matplotlib figure, but I can't find how to do this. Does anyone know how to do this ?

Quickly extract figure size in inches

To get width and height in inches I just use:

fig_width, fig_height = plt.gcf().get_size_inches()
print(fig_width, fig_height)

I put this here because this question is the first result that pops up when you search 'get matplotlib figure size', and the api most naturally works in inches, not pixels.

import matplotlib.plt
fig = plt.figure()
size = fig.get_size_inches()*fig.dpi # size in pixels

To do it for the current figure,

fig = plt.gcf()
size = fig.get_size_inches()*fig.dpi # size in pixels

You can get the same info by doing:

bbox = fig.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
width, height = bbox.width*fig.dpi, bbox.height*fig.dpi
