We rate this board to be able to hold a 350 lb person. As you start getting over 250 lbs, it gets harder to ride though and you will have to be a more skilled rider to deal with the board at that higher weight class.
If you are a beginner and 300 lbs, I would point you towards our 14’ x 8" thick inflatable that we rate for up to 800 lbs. It’s a beast, but still rolls up almost as small as this one when deflated.
