Yeah, most common is 44:16 and good for show.
Assuming you are building a rider or racer, this can be tweaked based on your riding needs, track, and/or tire size. Each tooth change in the back is equal to more than two in the front... meaning a chain wheel change will give you a finer adjustment; while, a freewheel change will be much more dramatic.
I assume you have the stock Sugino chainring for those Maxi Crosses? If not, it should color match both arms & spider and have the smooth finish like the spider... Preferably with raw teeth although I have seen full anno rings as well.
Here are some gear ratio chart links if you're still interested... or even want that much information...
