Getting the actual size of map canvas using PyQGIS

Question

How to get pixel size of canvas in QGIS? It is possibly by Python. I mean this red rectangle area in the image.

example

what do you mean with dataframe? If you mean a raster-layer than the pixelsize is in the properties — Curlew, Commented Mar 20, 2013 at 20:33

You can get those values with this code :

qgis.utils.iface.mapCanvas().size()

This returns a QSize object. You can catch width and height directly with

canvasSize = qgis.utils.iface.mapCanvas().size()    
print("Width : " + str(canvasSize.width()) + " / Height : " + str(canvasSize.height()))
