The handling of numbers and units in Studio is always something that raises questions and over the years I’ve tackled it in various articles. But one thing I don’t believe I have specifically addressed, and I do see this rear its head from time to time, is how to handle the spaces between a number and its unit. So it thought it might be useful to tackle it in a simple article so I have a reference point when asked this question, and perhaps it’ll be useful for you at the same time.

A couple of years ago I wrote an article on the SDL blog explaining the differences between Project Settings and Global Settings. Things have changed a little now, although the principle is the same, and Studio 2014 has a different interface so I thought, given the number of times this still comes up, that I’d refresh the article a little and have another go at making this clear.
