Double-fold tape uses a wider cut strip, so the strip width changes much faster than the finished binding width people see on the edge.

Wider yardage cuts down strip count, which is especially helpful when you want fewer joins in visible necklines or armholes.
A simple sizing rule is finished width times 2 for single-fold tape and times 4 for double-fold tape. That is why even a narrow finished binding often needs a surprisingly wide cut strip.
Add around 8 to 12 inches for joins, mitered corners, and handling. Long continuous runs, tight curves, or thick fabrics usually deserve the higher end of that allowance.
Each strip contributes roughly one fabric width of usable bias length. Wider fabric means every strip yields more tape, so you need fewer strips to reach the same total perimeter.
Continuous bias is worth it when you need long uninterrupted yardage for piping, quilts, or garment facings. It reduces joins, but the same finished-width sizing rule still applies.
