Have you got any scales? It's a bit difficult going off "egg-sized" and I'm not entirely sure whether you're referring to gram weight or gram carb content. There have rarely been potatoes in this house for the last five years, so I can't weigh any and show you a picture.
A potato that has 15 grams of carbs would on average weigh around 100g. This is based on the rough estimate that potatoes are around 15% carb (being otherwise mostly water). The internet says that one medium russet potato weighs about 170 grams or six ounces, and the potato is about 4 inches long. I would expect there to be around 26 or 27 grams of carb in that one potato.
The attached picture shows (or says it shows) one single 100g potato.
Does that help?
