In Word 2013, is there a way to adjust the vertical spacing between lines of an equation?? I've tried the "space after" and the "line spacing" as I would for normal lines of text, but they don't do anything. I think it has to do with the fact that I'm shift-entering each line, so that I can align at the "=" sign?? And hence, the usual line spacing functions don't work. It's very annoying, as I think the lines are too "scrunched" vertically and it makes it hard to read and follow each step. Any ideas??

Here's a way to do it in the Word 2013 Equation Editor, using VBA and the under-the-hood command codes detailed in Unicode Tech Note 28.

**First,** to illustrate the process, here's how you make a basic equation array using VBA:

- Insert a new-style equation in your document.
- Select it (or put the cursor somewhere inside it).
- Hit Alt+F11 to open the VBA editor.
- Hit Ctl+G or click in the "Immediate" pane.
Enter the following two lines, hitting Enter after each one:

`Selection.OMaths(1).Range.Text=ChrW(&h2588) & "(L1&=R1@L2&=R2)" Selection.OMaths(1).BuildUp`

The result is a normal two-equation array: Notice that there is not much space between the first and second lines.

**Now, to add the spacing:**

- Do steps 1-4 above.
Enter following line and hit Enter:

`Selection.OMaths(1).Range.Text=ChrW(&h2588) & "(L1&=R1@" & ChrW(&h27e1) & "(2&" & ChrW(&h22c2) & ")" &"L2&=R2)"`

For those with full Unicode support in your browser and OS, you can try copying the following line and pasting it into the equation, but that doesn't work as well on my system as the VBA does.

█(L1&=R1@⟡(2&⋂)L2&=R2)

You will see strange-looking text in your equation - don't panic! ---

Enter this line and hit Enter, just like above:

`Selection.OMaths(1).BuildUp`

You will see the equation array again, but this time with vertical space! ---

**Before and after:**

**The good news:** Once you've done this one time, you can save the equation as a Building Block (see also Greg Maxey's page). Then all you have to do is insert the equation from the Insert | Symbols | Equation dropdown, and edit `L1`

through `R2`

to include what you want.

**Explanation**: The (`ChrW(&h27e1) & "(2&" & ChrW(&h22c2) & ")"`

) is a *phantom* (`ChrW(&h27e1)`

) that does not appear and has zero width (`2`

), and that is the same height as a `\bigcap`

(`ChrW(&h22c2)`

). That `\bigcap`

takes up vertical space, which is added to the second row to push it down below the first row. You can select the phantom at the beginning of the second row, and if you delete it the extra space will disappear.

If you need vertical space elsewhere, you can copy and paste the phantom (`⟡(2&⋂)`

) into your equation and press Space to build it up.

I enjoyed the VBA answer. I've found that a much easier solution is simply making two (or more) equation boxes and selecting the box above where a space should be. Then, selecting the paragraph options, change the line spacing to "double" and now the top equation is elongated laterally to incorporate a space.
