Calculation of patch area in a 2D geometry

I have a very simple 2D channel flow of 1 unit length height.
When using the following code to determine the inlet patch area I get the value 0.25 instead of the expected value of 1:
scalar area = gSum(mesh.magSf().boundaryField()["inlet"]); Info << "Inlet area: " << area << endl;
Thank you in advance,

I think you are calculating area not the height. Even in 2D, there is one cell thickness along z direction. Check what is the length you have given in z direction in blockMesh and divide the area by this length, you will get the height !!
Hope this helps !!
Thanks and Regards
