One complete example

From measurements to a drafting plan

Follow one full-circle example from the numbers you enter to the layout decision. Every result below is generated by the calculator's current formula.

  1. Measuring the waist for the 28 inch example

    Step 1 · Input

    Enter one realistic example

    Start with a 28 inch waist and the calculator defaults.

    Waist
    28"
    Ease
    0.5"
    Skirt length
    24"
    Hem allowance
    0.75"
    Learn how to take the measurements
  2. Drafting the calculated circle skirt radii

    Step 2 · Calculate

    Read the calculated radii

    The waist, ease, length, and hem allowance resolve into a draft you can verify.

    Adjusted waist
    28.5"
    Waist radius
    4.536"
    Hem radius
    29.286"
    Check the radius formula
  3. Checking circle skirt pattern pieces against fabric width

    Step 3 · Layout

    Check the fabric before cutting

    Confirm the pattern fits before committing to fabric.

    Fabric width
    60"
    Pattern diameter
    58.572"
    Estimated fabric
    1.65 yd
    Layout
    4 quarter panels
    Plan for your fabric width
  4. Illustration of three finished circle skirt silhouettes

    Step 4 · Outcome

    Preview the finished sweep

    Use the finished silhouette as a fullness reference, not as a customer result.

    Skirt sweep
    360°
    Finished length
    24"
    Image status
    Illustrative outcome
    Compare circle skirt fullness

Replace the example with your own measurements to get a pattern preview and fabric recommendation.
