Does the idea ratio change if you run a 24 or 26? I have a 2.13 on my 26" and like the ratio a lot. And I am now trying to figure out what ratio to go with on my new 24 build. I have been told by a lot of people to go 2.3? Does the difference between the 24 and 26 make up the difference in the ratio?
28/12 is money. it's one of the closest ratios to 36/16. 27/12 is equivilent to 36/16, but you may have a tough time finding a 27t chainwheel. I think animal may make one.

Different wheel diameters will affect how far you travel with one revolution of the cranks. The same ratios will also feel very different. To get similar feel and distance you need to look at gear inches. On my 26" SS I like to run 32x17. It fits the type of riding I do and the terrain I like. When I got my 29er I wanted it to feel about the same. 32x19 gets me almost the same gear inches on the bigger wheels.
There's a calculator here for coming up with the numbers. Set the first slider in the first group to your front ring and the rest to 0. Set the first slider in the second group to your rear cog and then the rest to 0. Pick the 26" wheel size and hit submit. It will spit out some numbers. GI is your gear inches and RT is your gear ratio. Now go back and enter 24" wheel and play with the rings and cogs until you get a similar GI number. That will get you close. You may still need to go +/- a tooth on your ring or cog to get it to feel exactly like you want it to.
