Bug summary

The size of the text infig.suptitle is different if I specify the size of the text directly, or inside thefontdict={...}

Code for reproduction

importmatplotlib.pyplotaspltfig=plt.figure(figsize=(8,3),layout='constrained')f0,f1=fig.subfigures(1,2)f0.suptitle('xxxXXX',fontdict=dict(family='Candara',size=30))f1.suptitle('xxxXXX',size=30,fontdict=dict(family='Candara'))plt.show()

Actual outcome

Expected outcome

I expected text of the same size.
In the example, I have used subfigures but using a figure (twice) I had the same results.
Further, using a single figure with 2 subplots,ax0.set_title(..., size=..., fontdict{...}) andax1.set_title(..., fontdict={..., size=...}) gives titles with the same size.
