I have a 30 inch inseam and was wondering what the correct saddle height is for me. I am riding a Giant OCR2 and have the the height set at 26 inches from center of bottom bracket to top of seat. Does this sound too high, too low or just right? Thanks.

What size cranks? I don't like the formulaes that don't take crank-length into consideration...

They are the stock cranks, I don't know. This is what it says on the webpage. ( TruVativ Touro, 30/42/52T)

I would say they are approximately 7.5 inches from the middle of the BB to the bottom.

There are many schools of thought on fitting, but in the end your preference rules. One guideline is if you can put your heel on the pedal with your leg straight, you're about right. Your leg should not be quite straight with the ball of your foot on the pedal at the farthest point. If your butt rocks from side to side because your leg is too extended on the down stroke, your seat is too high. However you can't look at seat height in isolation. Body tilt, reach, seat fore/aft positioning play a role too.

Correct saddle height depends on a lot of factors, including how you sit on the saddle, how much setback you have, what kind of shoes/pedals you are using, how big are your feet, your pedalling style, etc.

Formulas based on leg length are very approximate. Better is to sit on your bike, warm up a little while, and just make sure you have some bend in your knee at the bottom of your pedal stroke. In their books, Lennard Zinn and Andy Pruitt recommend a knee angle of 25 to 35 degrees (more bend for sprinters and mountain bikers).
