Ease Distribution Calculator

Wearing ease is the extra room a garment needs beyond your exact body measurements so you can move, sit, and breathe in it -- a pattern drafted at your literal bust measurement would fit like a second skin, not clothing. This calculator adds a different ease allowance to each of the bust, waist, and hip based on the Fit Type you pick: Close Fit adds the least (2.5 in at the bust, 1 in at the waist, 2 in at the hip) for a fitted silhouette, Standard Fit steps that up to a comfortable everyday amount (4/2/3 in), Relaxed Fit adds more room again (6/4/5 in), and Oversized adds the most by far (10/8/8 in) for a deliberately loose, drapey garment. Each of the three body measurements only affects its own finished dimension -- Bust Measurement drives Finished Bust, Waist Measurement drives Finished Waist, and Hip Measurement drives Finished Hip -- because the calculator simply adds the fit type's ease allowance directly onto whichever body measurement it corresponds to, with no cross-influence between them.

Raising Bust Measurement always raises Finished Bust in lockstep, one inch for one inch, and Bust Measurement is also the only body measurement that feeds the Bust Front Quarter and Bust Back Quarter pattern-piece figures. Ease per Side Seam and Cross-Back Ease, by contrast, are fractions of the bust ease allowance alone -- they change with Fit Type and stay fixed no matter what body measurements you enter.
