I'm planning to use Tiny Tin Troops flags for my Napoleonics but not sure which size to use. So twofold question what size suits 10 or 12mm and what size are the Pendraken flags? Looking at Prussians initially.

We scale our own flags to around 11-12mm diameter to give a 'real life' size of around 6ft.

The Tiny Tin flags are all listed by diameter, so you can click the filters down the left column to pick the size you'd like.  10mm or 12mm would come down to personal preference really.  I'd lean towards the 12mm so that they stand out on the table.

Thanks Leon exactly the answer I was hoping for, 12mm it is.

No worries!
