pane size

[g861]

i have been told there is a certain proportion for the pane size on georgian sash does anybody know what this is thanks

At a guess it is either

a) Use the golden section - i.e. if the width is 1 then the height is 1.618

b) Make a square from the width and the height is the diagonal of the square, which results in a shorter pane than (a)

It's not true. They come in all sizes, the only rule being that they are mostly vertical rectangles. There are exceptions to this, square and horizontal rectangles can be found.
The parameter is usually the size of opening, which is often a convenient whole number of inches such as 40x60 but this is down to the architect/designer. Then the pane sizes follow on inevitably, the only decision being the number across and vertically.

There are other factors that come into play too.
The maximum size possible was limited by how big a piece could be trimmed from the spun plate of glass, the resultant "bullseyes" were either re-worked or sold as glazing for cheaper housing.

Another factor is that the panes for both upper and lower sashes should be of the same size.

As glazing production methods improved the more wealthy had the glazing bars removed and larger panes installed.

As opener has stated, the golden mean or section was often employed by architects of the day and this had an impact on all parts of the window, from overall size to glazing bar sections to the often seen manner in which windows on higher floors often got reduced in height.

Bit of a myth the above. You can nearly always find some part of a rectangular structure which falls near the golden ratio, but then the other bits won't. e.g. if the opening does then the panes won't, or vice versa, and so on.
Opening sizes are usually simple ratios 1:2, 2:3, etc.
Have a look at any big georgian facade and you will see any ratio you want at some point.

Any chance you could make that Photo a little larger?

What, you want to see the whole street?

No, I want to print it out and paper my walls in one hit.

Why is it a myth. The architects of the day used the ratio in the design of the building and it had an impact on everything else. As did brick sizes.

Well they didn't, that's the point - it's a myth.The problem with the golden ratio is that you can apply it to the first rectangle but then it won't work for any of the others, unless the divisions are in the same ratio e.g. a rectangle quartered 2x2. It also won't work if the dividing members have dimensions i.e. thicker than a line.
It can be made to fit somewhere on any rectangular facade as some parts are bound to be close, depending on where you take the line - the enclosing rectangle, the rectangle enclosed, a subdivision such as a pane size, etc etc.
