Change measurement units and rulers
InCopy includes a vertical depth ruler
for copyfitting text in Galley and Story views, as well as horizontal
and vertical rulers in Layout view for measuring layouts. By default,
rulers begin measuring from the upper-left corner of a page or spread.
You can change this by moving the zero point.
You can work with several standard measurement units, change
these settings at any time, and temporarily override the
current measurement units as you enter a value. Changing the measurement
units doesn’t move guides, grids, and objects, so when ruler tick
marks change, they might not line up with objects aligned to the
old tick marks.

You
can set up different measurement systems for horizontal and vertical
rulers. For example, many newspapers measure horizontal layouts
in picas and vertical text stories in inches. The system you select
for the horizontal ruler governs tabs, margins, indents, and other
measurements. Each spread has its own vertical ruler; however, all
vertical rulers use the same settings you specify in the
Units & Increments section of the Preferences dialog box.
The default unit of measure for the rulers is picas (a pica equals
12 points). You can change the ruler units and control where the
major tick marks appear on a ruler. For example, if you change the
ruler unit for the vertical ruler to 12 points, a major ruler increment
appears every 12 points (if such a display is possible in the current
magnification). The tick mark labels include your customized major tick
marks, so when the ruler reads 3 in the same example, it marks the
third instance of the 12‑point increment, or 36 points.

Setting custom ruler increments in the vertical
ruler is useful for lining up a ruler’s major tick marks with a
baseline grid.
Specify the measurement units
You can set custom measurement
units for the on‑screen rulers and for use in panels and dialog
boxes. You can also change these settings at any time and temporarily
override the current measurement units as you enter a value.
Choose Edit > Preferences > Units
& Increments (Windows) or InCopy > Preferences >
Units & Increments (Mac OS).
For Horizontal and Vertical, choose the measurement system
you want to use for horizontal and vertical dimensions in rulers,
dialog boxes, and panels; choose Custom, and type the number of
points at which you want the ruler to display major tick marks.
Click OK.

You can also change ruler units by right-clicking
(Windows) or Control-clicking (Mac OS) a ruler, and choosing
the units from the context menu.
Override default measurement units
You can specify a unit of measurement
that is different from the default.

Highlight the existing value in a panel or dialog box,
and type the new value using the notation in the following table:
