Whenever I click the Field Calculator in the attribute table, I am prompted to created a script in order for it to calculate the area of a polygon. However, I do not want to use code in obtaining a simple area measurement.

I have searched everywhere and cannot find a solution for this. Any idea how to just obtain a simple area measurement for a polygon (without creating a script)?

There are two tabs under the field calculator - Expression and Function editor, i suppose you're referring to the function editor tab which requires coding skills.

If you stay on the Expression tab you just have to create a new field and use the following expression :


To calculate the area of the current feature.

    Alternatively, you can use $area to calculate the area (ellipsoidal measurement) vs. planimetric measurement of area ($geometry)

    The weird thing in the question is that the default displayed tab should be the expression tab ... not the other ...
