<br>
Create a unique field in the attribute table of your polygon layer, for example an ordinal number of the features ($rownum in field calculator)<br>
Add the same polygon layer twice to your QGIS project. Rename one of them not to mix them up. Use the Vector/Geoprcessing/Union (or intersection) between the two layers (refering to the same shape file).<br>
In the result you will get the columns of the two layers, names are changed to be unique (e.g. if you created an id column, then you get id and id_2). You can ignore/delete those polygons where id = id_2.<br>
Add an area column to the result using the field calculator.<br>
<br>
I hope it helps you.<br>
<br>
Best regards,<br>

Hi,<br>
I'm using qGis 2.4 and I want to know the overlap area of many polygons of<br>
the same shape. How can I do it? There any tool to do it or I have to do<br>
some steps? There are too many polygons to create separate shapes for<br>
everyone and make clips.<br>
<br>
Thanks a lot.<br>
<br>
<br>
