Table for Calculating a Half-Circle Skirt With Fixed Parameters  
    Key Skirt Parameters            
   
If you plan to make gathers or pleats at the waist, calculate its total length and fill in the resulting value.
Waist Circumference (cm)
 
Skirt w/o Train Drawing
       
    Front Skirt Length (cm)            
   
Use Back Skirt Length if there is no train.
Back Seam Length (Train Included) (cm)
 
Skirt with Train Drawing
       
    Finished Waistband Width (cm)            
    Width of Skirt Fabric (cm)            
   
Put "1" if there is no gathering along the waist.
Waist Gathering Ratio
           
    Radii Calculations            
               
   
This value is equal to WC if there is no gathering.
Radii Calculations
           
    Waist Opening Radius (R1) (cm)            
   
If required fabric width including gathers or pleats along the waist exceeds the actual fabric width, then you cannot cut it this way. Reduce the Waist Gathering Ratio, use wider fabric, or divide the skirt in gores.
Bottom Edge Radius (R2) (cm)
           
    Side Radius (R3) (cm)            
    Side Radius (R4) (cm)            
    Side Skirt Length (cm)            
                   
   
Add waistband fabric consumption to skirt fabric consumption depending on situation.
