What is the seam allowance for chinos?

• A. 5 cm
• B. 2 cm
• C. 3 cm
• D. 4 cm

Answer: (C)

Seam allowance is the extra fabric beyond the seam line that you leave to stitch and finish the garment. For chinos, a wider allowance is practical because the fabric is sturdy (cotton twill) and the pants involve several finishing steps—front fly, pockets, and a hem—that all require enough material to stitch neatly and still press cleanly. Three centimeters gives ample room to sew through multiple layers, trim or grade when needed, and still have a neat, durable final seam. Using less space, like two centimeters, can be tight on heavier fabric and with multiple finishing steps, while significantly more than three centimeters adds unnecessary bulk at the seams. So, three centimeters is chosen to balance durability, ease of finishing, and a clean look.
