+**Taper** mesh quality criterion represents the ratio of the areas
+of two triangles separated by a diagonal within a quadrilateral face.
+
+::
+
+	**JA = 0.25 * (A1 + A2 + A3 + A4)**
+	**TAPER = MAX(|A1/JA - 1|, |A2/JA - 1|, |A3/JA - 1|, |A4/JA - 1|)**
+
+*To apply the Taper quality criterion to your mesh:*

+#. Display your mesh in the viewer.
+#. Choose **Controls > Face Controls > Taper** or click *"Taper"* button |img| in the toolbar.
+
+
+   Your mesh will be displayed in the viewer with its elements colored according to the applied mesh quality control criterion:
