All this time I've been thinking my guides was square!

Think I may be in a muddle. 

I thought I'd made my guides so they were square and equally spaced. 

It turns out that they're not. What have I done wrong? 

Bit concerned as I've now almost finished an entire book!

What dimensions are the pages?

You have a rectangle (not a square) inside the square page. Make your margins 25 20 22.5 22.5 to give yourself a square inside a square.

Will the layout columns update automatically?

Thanks so much. 

I made a copy and then applied that to the whole document and began the long process of tweaking but then I realised that that meant that my outside border wouldn't be uniform. 

It's the same thing if I make it 25, 22.5, 22.5, 22.5 isn't it?
