Matplotlib default figure size

This post introduces how to check the default figure  size in Matplotlib, and how to change the figure size.

The default value is [8.0, 6.0] which can be changed of course.
To know all the default values just inspect the value of ‘rcParams’

print(plt.rcParams)  # it will tell you all default setting in Matplotlib
 
print(plt.rcParams.get('figure.figsize'))

To change the figure size.

you can use the following:

plt.figure(figsize=(20,10))

fig, ax = plt.subplots(figsize=(20, 10))
