How to match my layout grid with my margins, columns and baseline grid in indesign

Please forgive me if this questions sounds a little off, but I’m struggling to understand it let alone explain to you.

When setting up a document in InDesign, I want all of my columns and grids to be within relationship with one another. To do this I understand that everything should be based on my leading value.

For example my leading value is 12pt, so in relation to that I set up the gutters on my margins and lay out grid (guides) to be 12pt and also I do the same in the grid preferences.

After my Margins and columns are set and my baseline grid is turned on, I then create my layout grid and this is where my brain simply explodes because the layout grid never lines up with the baseline grid when working with a aspect ratio.

I hope you all understand what it is I’m trying to say and can anyone pleeeeease help me get past this block?

What I’m hoping to achieve from this answer is for me to be able to setup all of my grids and margins on any size page, set at any leading value at any aspect ratio.

Thank you so much for your help!

I’ll start off by pointing out that fitting a 5×7 box into a 2×3 area (plus some gutters (which will only make the area thinner rather than fatter). You may find those horizontal guides very restrictive here. You can’t even fit 7 into 5 anyway; they’re both primes.

What we can do, however, is to at least get those horizontal guides to line up with the baseline. I’ll show you my fairly visual way of creating simple grids like this. I’ll write as if I’m making a grid from scratch:

  1. Start by looking at your leading. As you want to fit 1×1 and 2×2 boxes into your grid, you’ll need the leading to be the same as the gutter width (or the square isn’t going to line up perfectly when it is 2×2 or larger)… I’m going to use 10.8pt here (no particular reason).
  2. Choose the number columns and set your gutter width the same as the leading chosen for the baseline grid. I’ll use 5 columns too.
  3. Experiment with squares, lining them up with the baseline grid (ignore the current columns width!). How many lines tall and wide your squares are will influence how much margin you end up with.
  4. If we settle on 8 lines then the square is 30.48mm wide; this is the column width that we want. A4 page width is 210, we have 5 columns and 10.8pt (3.81mm) leading & gutters so add up the width of all your 5 columns and 4 gutters (167.64mm in this case) and subtract that off your page width and divide by two so you get what a single margin would be ((210mm-167.64mm)/2 = 21.18mm). Insert this as your margins.
  5. Repeat this for the height/top and bottom margins.

You’ll end up with something like this:

(I’ve nudged my grid up a bit too at the end)

This is a grid where the ratio between the squares and the gutters is 8:1. If you made squares that were 9 lines high then it’d be 9:1, etc. You can probably scale these squares up and down and measure the total width and space between the squares for new margin/leading values if you’re happy with the ratio but want a bit less or more margin. If you want a different ratio of lines per square then you’ll need to go back a few steps. If you want to change the leading without scaling everything then you’ll need to start from scratch.

If you have specific margin widths then you’re going to have to come at it from a different angle. I found this post with linked, complicated, grid calculator that you may find useful:
