6.5x9 and 2x3 Sheet Film actual size.

The title kind of says it all.

Now that I have finally found some film holders for my Ziess Ikon Maximar 207/3 I need to find some film for them.
The holders take 6.5x9 film and I will probably end up cutting some down.
Yes I know I could just measure the film sheaths and go from there but I am curious as to exactly what size 6.5x9 film actually is.

And not to be too greedy what would the actual size of 2x3 Sheet Film.

thanks in advance.

I have some really old 6.5x9 negs that came with a camera-Dupont Defender, process ortho they measure 63.80 mm x 91.00 mm
Arista (Foma) 2x3 measures 55.90 mm x 82.10mm *all more or less
I think Freestyle sells Efke in 6.5x9

Thanks Brian.
That's exactly what I needed.
