Banner ribbon is driven by the full hanging span, not just the triangle widths, so side tails make a noticeable difference in total trim length.

Wider fabric improves pennant nesting efficiency, but the banner still needs enough ribbon for the full run plus generous hanging tails.
Add the widths of all pennants, the gaps between them, and the extra tails on both ends for hanging. Ignoring the side tails is the most common reason banners come out too short.
Fabric yardage depends on how many pennants fit across the fabric width and how many rows you need to cut, not just on the total triangle area. That is why fabric width matters so much.
Pennants around 5 to 7 inches wide and 7 to 10 inches tall work well for tabletops, mantels, and short wall runs. Larger rooms and market displays usually need taller flags or more spacing.
Both can work. Edge-to-edge feels fuller, while 1 to 2 inch gaps create a lighter look and make lettering easier to read. The calculator lets you compare those styles quickly.
