Gather Calculator — Fabric for Gathered Sections
Calculate fabric width needed for gathered sections based on desired fullness ratio.
The width after gathering is complete
How much extra fabric for the gathered effect
Split gathering across multiple panels for even distribution
Affects recommended fullness ratio — lightweight fabrics suit more gathering
How We Calculate This
Gathered fabric width = finished width x fullness ratio.
The formula
Fabric width = Finished width × Fullness ratio
When using multiple panels, the total fabric is divided equally across panels. Seam allowances are added per panel edge.
