Hi there and welcome
Do you mean the spacing between lines James? Or between words?
and which version of word are you using?
To do this you use the Paragraph Spacing button on the Design tab,
Click Design > Paragraph Spacing.
Move your cursor over each of the spacing options under Built-In, and notice how the line spacing changes.
Click the option you want which will be double Space
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
how did you go James?
