Classic/NeoGeo button spacing

[nipsmg]

I've been reading a lot of posts on button spacing, and I know a lot of it is a matter of preference.

I personally like the 1.5in between buttons for button spacing.

However, I'm having trouble positioning the 2 rows in relation to each other, and the 7th "neogeo" button.

I know that with the following config:

    1  2  3
    4  5  6    
  7

1-2-3 are 1.5in apart horizontally
4-5-6 are 1.5in apart horizontally

what's standard for between 1 and 4
what's standard for horizontal/vertical offsets between 4 and 7?

Any help would be appreciated.

I don't know what the standard is... but here is what I did:

I spaced mine 1 and 5/8" rather than 1 1/2" but the same method should work well with 1.5".  I just measured out the 7th button to where it was 1 and 5/8" down and 1 and 5/8" to the left of button 4.  So if you imagine a 4 by 3 grid like so:

1234
5678
abcd

where number or letter is a button, 2-4 and 6-8 are the six buttons and a would be where the 7th button would be.  Again... I have no idea what the standard is, but this feels very good to me.  There are pics of how this looks here:

See, I just sat down with Paint Shop Pro, made a button template from Happ's sizes, laid out my 2x3 grid on 1.5" centers (snapping to guides and a 100dpi workspace helps here), grouped the button array and rotated it 45 degrees, and pasted in another button 1.5" apart from the appropriate button.  Add the new button to the group, rotate 45 degrees back to horizontal, and printed it out to full size.

  Yeah, you can do simple math to figure out the sizing (the hypotenuse is 1.5", the angle is 45, the math is relatively easy), but most rulers aren't precise enough to be any help.
