How many times have you needed to find the center of a document and had to resort to the calculator to find it? Here are three ways, and none requires any math:

* Make sure that the Rulers are showing and then click SelectâžœAll followed by EditâžœFree Transform, bring in a horizontal and a vertical guide (click a Ruler and drag into the document) so that they cross in the center, and then press Escape. The center of your document will be where the two guides cross.


* Although there’s nothing wrong with the preceding method, the following is slightly quicker if the current layer is filled completely. First, make sure that the Rulers are showing and that View➜Snap is turned on. Next, slowly drag in a horizontal guide to the center and then a vertical guide, letting go when you feel them snap to the center of the document.Where the two guides cross will be the center of your document. You can include the preceding steps in an action, assign a keyboard function key, and find the center of any document, regardless of its dimensions, at the press of a key.
Just make sure that before you start recording, or even during the recording, the unit of measure for the Rulers is set to read in percentages and not fixed units, such as pixels. To change the units, right-click (Windows), Ctrl-click (Mac OS) on a Ruler and choose Percentages from the contextual menu.


* This third method doesn’t require the rulers to be visible: Choose View➜New Guide. In the New Guide dialog box, select the Horizontal radio button, enter 50% in the Position text field, and then click OK. Enter the dialog box a second time, select the Vertical radio button, enter 50% in the Position text field, and click the OK button. As with the previous method, you can record the steps as an action and assign a function key for quick access.
