There is no set weight you can say is overweight. Kind of like people come in far different weights. At minimum you have to measure someone's height along with their weight and even then it isn't entirely accurate. Muscle also weighs more than fat. I had a pig over 3lbs that was solid muscle. Far from overweight but above the average. I had a smaller female pig at 2lbs that was extremely overweight. Lots of fat and no muscle. You cannot measure by a number. You will have to look at your pig. On most animals they say you should be able to feel but not see the ribs. Unfortunately that does not work well on guinea pigs. Instead you will have to try to measure how much fat there is. How squishy does the pig feel? Are there fat rolls? A really wide belly that hangs out over the hips? A big chin roll? Can you feel muscle across the shoulders and hips, just squishy fat, or solid bone? A pig should feel fairly solid to slightly squishy with most of the bone covered but not like a little squishy pillow.

The larger your cage and more floor time the thinner and more solid the pigs feel but it's from muscle. You still can't feel their bones. The difference is just amazing when I let my pigs around in spaces like the 12x24' horse stalls. They look thinner and lighter after a month but when you pick them up they feel heavier and not at all squishy. I think that's part of the reason most of mine have lived to 8-9years old. They are in excellent shape physically.
