`Except that those formulas don't produce the "standard" dimensions as I
``understand them. Unless I'm mistaken the sizes are as follows:
`
Small 1 x 9/16
Medium 1 3/8 x 25/32
Large 1 3/4 x 1
Are these not the dimensions you started with?
Given those dimensions, the formulae would be...
Height = (5 + 3x)/8
Width = (11 + 7x)/32
...where x is the number of pips.

I've read some of debates about the correct formula for dimensions
of larger pieces...

Copied from my previous treatise on the matter:
=====
A pyramid is
(5+3x)/14 inches wide, rounded to the nearest 32nd and
(5+3x)/8 inches tall
where x is the number of pips.
Which gives us the currently published values AND makes the obsessive
mathematician in me happy.
=====
The tricky part is, of course, rounding 14ths to the nearest 32nd.
