i'm planning to create some floor tiles for use online and table top. i'm wondering what the best size and resolution would be for these applications. i've already made a nice set at 50x50 px and 72dpi but before i continue i'd like to know what would be best.

i've been thinking 1 inch squares at 96 dpi for online and 1 inch squares at 200-300 dpi for printing.

i'm old school. i've never played online or used printable tiles so any advice would be great...
