Note: Updated Jan 2011 with the new larger BSA neckerchief size.
The BSA’s Insignia Guide says this about the size and shape of the neckerchief, “Official neckerchiefs are triangular in shape.” There is a more info about how to wear it, who chooses the neckerchief (the troop), who approves special neckerchiefs (the council), and so on. It does say that special neckerchiefs are “the same size as official ones”. Oddly, they don’t say what size that is.
So I researched it. One reason to have a bigger neckerchief is so it can be used as a triangular bandage, so I also checked the common sizes for those, including the ANSI-standard size.

- U.S. Scouting Collectibles, George Cuhaj, 2001, p 79. Neckerchiefs are describes as “Full Square, 28 x 32”. I am assuming that the cloth has shrunk along one axis of the weave. Other neckerchiefs are described as “Full Square 32 x 32”.
- Handbook for Scoutmasters, 1938, p 292. “of cotton, 30 inches square (or triangular in shape, cut diagonally from such a square), in plain or combination colors, as selected by the Troop, District, or Council.”
- Personal neckerchiefs, I made the measurements.
