Which tool is a 6-inch ruler with a movable marker used for short measurements like hems and seam widths?

• A. Ruler
• B. Measuring tape
• C. Seam gauge
• D. Caliper

Answer: (C)

A seam gauge is the tool designed for quick, precise work on small fabric measurements like hems and seam allowances. It combines a short, typically six-inch ruler with a movable marker that slides along the edge. That slider lets you set the exact distance you need (for example, a 5/8 inch hem or a specific seam width) and then use it as a repeatable guide as you mark or fold. Why it’s the best fit: plain rulers are just fixed scales and don’t offer a movable reference point for quick repeated measurements. Measuring tapes are flexible and better for longer, curved distances but less suited to precise, small hems. Calipers measure thickness or gaps with high precision but aren’t practical for fabric hemming or seam allowances. The seam gauge is built exactly for short measurements with a movable marker, making it ideal for hems and seam widths.
