Circle Skirts

Working Out Circle Skirts for your waist
The original equation for working out your waist radius for a circle skirt is:- (waist ÷ 4) x (7 ÷11)
- For a circle skirt, divide your waist measurement (including ease) by 6.28
- For a three quarter circle skirt, divide your waist measurement (including ease) by 4.71
- For a half circle skirt, divide your waist measurement (including ease) by 3.14

Figure 2: Comparison of Full Circle, 3/4 Circle and 1/2 Circle Skirts
This is an examples of the final pattern pieces for a full circle, a 3/4 circle and a 1/2 circle skirts made for the same waist measurement and to the same length.
Figure 3: Comparison of Full Circle, 3/4 Circle and 1/2 Circle Skirts
In Figure 2 it is obvious that the full circle skirt shape is a quarter of a full circle, but if it isn’t obvious that the other two shapes end up as a 3/4 circle skirt and 1/2 circle skirt, I have made copies and rotated them to show their final shapes in this image.
Figure 4: Comparison of Circle Skirts & Flared Skirts
Here is a comparison of what the final pattern pieces of flared and circle skirts look like.

Do you have the math for a child’s circle skirt? Would I use the same numbers?
is a wide a-skirt and a 1/4 or 1/8 circle skirt essentially the same thing?
