Measure to be sure.
Another advantage of using this type of foot is when sewing the seams for making half square triangles. You can place the metal guide on the diagonal line you drew on the squares...your seam will be 1/4" from that line. Be sure to sew both sides of the line before cutting on the line.
You cannot do this with a seam guide that is attached to the throat plate.
