Why Use This Tool?
- Supports standard Knife Pleats and Box Pleats.
- Calculates the exact fabric width required (usually 3:1 ratio).
- Determines the number of pleats based on your waist size.
- Generates a "Marking Pattern" (e.g., Pleat-Return-Pleat) so you can start chalking immediately.
How to Use It
- 1. Select your Unit (cm or inches).
- 2. Choose your Pleat Type (Knife or Box).
- 3. Enter the Finished Width (e.g., the waist measurement).
- 4. Enter your desired Pleat Size (how wide the visible part should be).
- 5. Click "Calculate" to get your fabric requirements and marking guide.
Frequently Asked Questions
How much fabric do pleats usually use?
A standard "full" pleat (where the return is double the width) uses a 3:1 ratio. This means if your waist is 70cm, you need 210cm of fabric (plus seam allowances). This tool calculates that exact requirement.
What is the "Return"?
The return (or depth) is the fabric folded *behind* the pleat. For a full pleat, the return is usually twice the width of the visible pleat.
Can I adjust the ratio?
This calculator assumes a standard 3:1 ratio for maximum fullness and best drape. This ensures the pleats touch each other on the back side.
