Using rulers, the measure tool,
guides, and grids
Rulers, the measure tool, guides, and grids help
you position images or elements precisely across
the width or length of an image.
Note: You can also align and distribute parts of an
image by using the Layers palette. (See “Moving and
aligning layer contents” on page 265.)
Using rulers
When visible, rulers appear along the top and left
side of the active window. Markers in the ruler
display the pointer’s position when you move it.
Changing the ruler origin (the 0, 0 mark on the top
and left rulers) lets you measure from a specific
point on the image.The ruler origin also deter-
mines the grid’s point of origin.
To display or hide rulers:
Choose View > Show Rulers or Hide Rulers.
To change the rulers’ zero origin:
1 To snap the ruler origin to guidelines or
gridlines, choose View > Snap to Guides or View >
Snap to Grid.
2
Position the pointer over the intersection of the
rulers in the upper left corner of the window, and
drag diagonally down onto the image. To make the
ruler origin snap to the ruler ticks, hold down Shift
as you drag. A set of cross hairs appears while you
drag, marking the new origin on the rulers.
Note: To reset the ruler origin to its default value,
double-click the upper left corner of the rulers.
Dragging to create new ruler origin and result
To change the rulers’ settings:
1
Do one of the following:
•
Double-click a ruler.
•
Choose File > Preferences > Units & Rulers.
2
For Units, choose a unit of measurement.
Note: Changing the units on the Info palette changes
the units on the rulers to match them.
3 For Width and Gutter, enter values for the
column size. You also can change the units.
Some layout programs use the column width
setting to specify the display of an image across
columns. The Image Size and Canvas Size
commands also use this setting. (See “Changing
the print dimensions and resolution of an image”
on page 49 and “Increasing the size of the work
canvas” on page 59.)
