# Size-Run Calculator

@AmyFayChandler

                Ordering clothing? Don’t buy the same number of every size.
                Enter your total units and let the bell curve tell you how many
                of each size to order. Fewer dead XL’s, fewer sold-out M’s.

How many sizes does this style come in?

                    S / M / L
                    S / M / L / XL
                    XS – XL
                    XS – XXL

                Size Curve

                    Standard works for most specialty retail. Core-heavy leans harder on M/L.
                    Plus-inclusive adds weight to XL/XXL.

                    Standard
