What is Size Ratio Calculation?
Dividing a total bulk PO into exact size-wise quantities based on buyer ratios is necessary for cutting planning, marker making, and accessory ordering.
Formula
Size Quantity = Total Order Quantity × (Size Ratio Value / Sum of All Ratio Values)
How to Calculate
Sum all size ratio numbers, then divide each size ratio by the total sum and multiply by total order quantity.
Example
Total Order = 6,000 pcs, Ratio S:M:L:XL = 1:2:2:1 (Sum = 6) → S = 1,000 pcs, M = 2,000 pcs, L = 2,000 pcs, XL = 1,000 pcs.
