uneven spacing between words in Pages when using justification

Hi,

I have searched for an answer to this but most threads end up without an answer that works. There must be a way though.

When using (full) justification in pages there are often uneven spaces between some words. Logically it would seem simple to set a rule that maintains even spacing but there doesn't seem to be this option. Changing the spacing between characters can help to a point, but it does depend on the length of each word in a paragraph etc.

Any ideas that actually work?

Thanks.
