Correct Length?

So let me ask you all a question... what is the correct length of jeans?

I have probably 7-8 pairs of jeans of various sizes and fits. There are a couple that seem like a little long. They drag on the ground and get wet if it's rainy. However, I also have a few pairs that seem like they're too short now. Like I've somehow shrunk them or perhaps they were always a bit too short and I'm just now noticing it. These pairs hit my foot right above the ground when I'm barefoot, so when I put on shoes it just seems like I'm waiting for the floodgates to open.

And don't even get me started on the different fits! You know how each retailer that sells jeans has different fits and types? The Limited has those different numbers, Old Navy has the flirt and sweetheart, etc... I wish someone sold The Courtney. I wish I could just walk into a store and know exactly what to buy.

Oh jeans!!! I both love and hate you so much!
