The back of the trousers will be approximately how many inches longer than the front?

• A. 1/2 inch
• B. 1 inch
• C. 7/8 inch
• D. 1 1/4 inch

Answer: (C)

When patterning trousers, the back needs extra length to accommodate the curvature of the buttocks and the seated posture. That extra length lets the fabric ease smoothly at the back and keeps the hem level when standing, while preventing the rear from riding up when you sit. About seven-eighths of an inch is the standard amount of difference used to achieve this balance. Smaller differences won’t provide enough ease and can cause the back to ride up; larger differences can make the back look baggy or cause other fit issues.
