Garment Ease Calculator

Garment Ease Calculator

Drafting or adjusting a garment pattern? This calculator adds the correct ease allowance to your body measurement for the fit you want.

Reference Ease Amounts

Fitted: +1in | Semi-Fitted: +2.5in | Loose: +4in | Oversized: +6in

Example

A 36-inch body measurement, semi-fitted style:

Finished Measurement = 36 + 2.5 = 38.5 inches

Why Zero Ease Isn't the Goal

Ease is deliberate extra room built into a garment beyond exact body measurements, allowing for basic movement and everyday comfort - a garment cut to your exact body measurement with zero ease would be uncomfortably tight and restrict simple actions like sitting, reaching, or breathing deeply.

These Are General Reference Ranges

Actual ease amounts vary somewhat by garment type, fabric stretch, and personal preference - a stretch knit fabric can use noticeably less ease than these reference woven-fabric figures while still feeling comfortable, since the fabric itself provides some give.
