My best fit is 28 waist, 33 length. I am 5'10, and 34 is a bit too long for me but 32 is a bit short when I sit down.
Since 28x33 is not common, I usually have to settle for 30x32 and wear a belt. Usually I have to drill new holes in my belts because the pre-drilled ones are way too loose...
Wow, with all these 32s and 34s, I must have rather stubby legs to be 6'1" and only have a 29" inseam. 😛
It probably depends more on the brand and how you like your jeans to fit.
My dad wears his jeans so that they don't quite cover the tops of his shoes. I wear mine so that they cover the tops of my shoes and a little extra.
That depends on if 33x34 is available, otherwise it's even (34x34).
