Both of Jeff's dumpsters are 12 feet long and 6 feet wide. Same footprint, same spot on your driveway. The difference is the walls: 43 inches on the 12-yard, 61 inches on the 16-yard. So this isn't a will-it-fit question. It comes down to two things, how much you're throwing away and how heavy it is.
Start with the weight, because it can end the conversation. If any serious amount of your load is concrete, dirt, shingles, or plaster and lath, it's the 12-yard, full stop. Jeff doesn't put heavy material in the 16 at all. Dense loads reach the trailer's legal limit long before they reach the top of a tall wall, so the bigger dumpster would only let you build a load that can't leave your driveway. Those four materials carry 1,000 pounds included and $50 a ton after that, weighed on the scale ticket.
If the load is ordinary stuff, furniture, boxes, drywall, cabinets, carpet, then it's a volume question. The 16 holds about a third more and costs $30 to $50 more depending on how many days you book. A garage cleanout or a single-room job fits the 12 comfortably. A full-house cleanout, a kitchen gut, or a barn clearing wants the 16, and running out of room mid-job is the mistake people regret most, because a second delivery costs a lot more than the $50 you saved.
There's one more reason to take the 12 even when volume is tight, and it's your back. Forty-three inches is a bit under waist height on most people. Sixty-one inches is chest height. If you're hand-loading heavy awkward pieces all afternoon, the lower wall is a different day.
Still stuck? That's fine, it's literally the question Jeff answers every day. Call or text (765) 238-1393 and describe the job, or try the size guide. Describe the job in pickup-truck loads and he'll name the size.
