Two wedges are used to help the respondent to estimate the portion size of wedge shaped foods. Each wedge has an overlapping arrow pointer that moves along the arc of the wedge.

The respondent can use the numbered increments along the length (radius) of the wedge and move the arrow to the alphabetized segments to describe the estimates (e.g., 9″E or 5″D).

The wedges are developed by Agricultural Research Service at the U.S. Department of Agriculture.
