What font size for logo on a 24x30 canvas?

[Fireball]

I'm going to have my first canvas done in a 24x30 size and am wanting to add my logo to the bottom right (it's a landscape). What size would the font need to be so that it's not humongous once the print is blown up?

It will be the same proportionally to what it is on any print. Think about it more in terms of viewing area and distance (e.g. If the artwork is going to be viewed up close, have it printed smaller).

Just so you know 72pt = 1in height on a standardized font.

Thanks Chris!
