Calculation method
Calculation method
Chosen garment target (cm)
Body inseam + user-selected garment offset.
Actual minus target (cm)
Actual garment inseam − chosen target.
Length to remove (cm)
Maximum of zero and actual minus target.
Extra length needed (cm)
Maximum of zero and target minus actual.
