I have put a minimum length of 90" on any tent choice for me. It's a little bit arbitrary but I'm more likely not to be cramped and I've found a few tents that aren't too heavy that meet that criteria. Fortunately (?) I don't have the money to spend on one right now so I have plenty of time to look. I'm hoping to be able to have something together by this summer when I have a little longer trip in the pre-planning stage. I'm sure carrying that big tent on my overnight trip this weekend will give me some incentive to start counting pennies.

With clothes the problem I often find is in sleeve length. I wear a 37" sleeve and unless a shirt or jacket specifies sleeve length (like dress shirts) or comes in a "Tall" size they will likely be too short for me. Even the Tall sizes are sometimes a crap shoot for proper sleeve length.
