# Horn width

For a rectangular horn, the largest dimension transverse to the stud axis. If no location is specified, the width is assumed to be measured at the horn face.

Example: in a horn whose face dimensions are 125 mm x 50 mm, the width is 125 mm and the thickness is 50 mm.

Sometimes for very wide bar horns the width may instead be called the length. For example, for a 300 mm wide bar horn someone may incorrectly say that the length is 300 mm. This use of "length" is potentially confusing because "length" refers to dimensions that are (generally) parallel to the stud axis.
