I bought these for my husband who is 6'3, roughly 240 lbs. Where his pants sit comfortably on his waist measured almost 46 inch in (I know what u might be thinking lol but please read whole review before you jump to conclusion) So at first I thought " shoot does he REALLY need to order that big a size? " No.  And here is why..
So,  his current jeans we're mostly, 38/32 but prefers 34 length when available, and they we're just a teeny bit tight,  especially after washing but they did stretch back out with wear as 100% cotton does. We wanted to try size 40. Had to get 40/32 since 34 wasn't available. They fit perfectly for his style and what he prefers.  If you like it really really baggy maybe go one size bigger but you would need a belt to keep up lol.  The pants actual physical measurements we're just teeny bit under 40 and length was actually 32. I think the only thing we think could be better is the leg opening at hem could stand to be a hair wider but I think that's personal preference,  and others may feel they are fine.  So yes we recommend =)
