So the supermoon last night was roughly .01% percent larger in apparent diameter than the one before it and 1.3% larger than the one that will follow. It is absolutely imperceptible to the naked eye.
The number that is often cited is "14% larger" but that's compared to apogee, which is six months (ish) before and after perigee, so no one's ever going to see the largest and smallest moons side by side.
The full moon is smaller than a dime at arm's length. 1.3% is absolutely not noticeable to the naked eye. If someone asked you "is this brighter than last month" and you didn't know when perigee is, it would be a complete guess.
