Grid Size for 16:9 project?

Hi, I'm giving the Grid and Snap to Grid options a go.

What is in your opinion the most optimal Grid Width/Height ratio to set for a 16:9 project filled with power of 2 images?

That is in regards to being able to snap everything exactly to the edges of the layout and to their own edges at the same time. Is that even possible?

16x16 seems to fit nicely and snuggly to my eyes but maybe i'm just not seeing something.

usually it depends on what you are doing in the layout. It's easy to change, so you can change it at any time.

Usually multiples of 8 are what I end up using, mainly 16 or 32. But not for any special reason other than the usual sprite widths.

And if you haven't already noticed, there is a glitch in the grid boxes, so when you change one, you have to hit enter or click the other grid box, or it will reset to the previous number when you click anywhere else.

I always use 1600x1200 for everything, and then change the aspect based on the user and all that.

I learned that practice from Blizzard, as they do that in Starcraft II.
