A 32 facing represents a facing length of 16mm.

This measurement system was developed by Eric Brand and measures the mm facing length measured from the tip of the mpc to a point where a 0.0015" metal gauge stops reading on the glass gauge. This stoppage point is actually twice the mm measurement. This, as I understand it, was done to make facing measurements easier by "stretching" or "expanding" the mm reading by doubling it. For example, a measurement of 2 on the gauge actually represents 1 mm. All commercial glass facing measurement gauges use the Brand system.

A short synopsis from Vytas Krass' response:

15mm = Brand 30 = short facing
16mm = Brand 32 = medium short facing
17mm = Brand 34+ = medium facing
18mm = Brand 36 = medium long facing
19mm = Brand 38 = long facing
20mm & up = very long facings

Note: (* in other countries the 17 mm facing length is considered to be short).

Please see photo for help in understanding the system.

p.s. Others may respond with a better explanation than mine.

p.p.s. Please do read Vytas's #29 response. He goes into great detail of how different facings affect the sound and playability in lower and upper registers.
