I've just been going through the range of Peco turnouts before buying a few.
The area of the layout being models is on the mainline, where prototype turnout would typically be a DV10 3/4, so I decided to go with the larges radius turnout. The larges one Peco offer is a AV7....

Hi Al,

For some reason Peco do not declare the radii of their points. It's not even on the packaging.

I've just done a quick Winrail drawing linking a series of Peco FS Large radius point together to form a semi circle and the radius appears to be just under a metre. (930mm is the best I can measure it at on the inside rail).

Hope this helps.

Expat.
