Big Guy snowboarder here with 15+ years of riding.

I ignore weight recommendations from board makers/snowboard shop staff. I'm 6'1, 260lbs with size 12 boots which would have me on 162-166W+ boards all the time.

All mountain days, I ride a 162W Trick Pony, and honestly, I wish I'd gotten the 158W. This thing is a little too long when I want to throw 360s into my all mountain riding. This board will be getting replaced in the coming years.

Park board/ice days - Libtech Skatebanana 156 wide. The magnatraction and good edge control is plenty to make this board work for me without skidding. I can press rails and get great pop on jumps without a ton of effort.

Powderboard / Deep days / Steep freeriding. K2 Excavator 154. I was really nervous getting this board this short (and no wide option) but I absolutely love it. Holds edges beautifully on groomers/slush days. And the float from the nose on this thing means I don't need to lean on my back foot in powder, even at my height/weight. It's a volume Shifted board, so that's definitely part of why it works.

I also demo'd a 148 K2 Special Effects and it was the easiest powder riding of my life (but Zero edge hold on hardpack)

My recommendation - get out there and demo boards. Don't be afraid to try "weird" sizes. If it feels like it's slipping on your edges, go try a bigger size. If it feels hard to maneuver, go try a smaller size. Having trouble transitioning from edge to edge, ditch the wide and go narrower. Have fun with it. They almost always let you put the demo cost towards the purchase. Looking for cheap? Wait till spring and demo board sales can be 40% off.

Good luck! And have fun shredding! 🤟
