berth/seat cushions sizes/based on standard dimensions?

[jacobjohn7]

would anyone know the sizes of berth/seating cushions on a particular boat.. are the widths fairly standard.. (obviously lengths vary) and galley widths also? as standard dimension on a certain sized boat? I have a buckingham 21 (1976) and looking at what I may need when either covering existing or adding third berth cushion, as I attempt to convert the two seat areas at the helm into a width on double berth, by introducing a moveable section and cushion over galley between the two.
Any help would be greatly appreciated!
thanks

I'm afraid nothing is standard. Even two builds of the same boat can differ. You have to go to the boat and measure it, alas
