In most ordinary coins, the heads side is typically heavier than the tails side.
This slight weight difference is primarily due to the design, where portraits or more intricate imagery on the heads side require a slightly greater amount of metal distribution. This subtle imbalance can cause a coin’s center of mass to be slightly shifted towards the heads side.
This weight difference can influence how the coin behaves when flipped or spun:
- Flipping: The slight weight bias can subtly favor the coin landing with the heavier side (heads) face down, making it appear that tails comes up more often. Studies suggest that coins are slightly more likely to land on the same side they started on, with an average same-side bias of about 50.8%.
- Spinning: When a coin is spun on its edge, the imbalance can become more pronounced. Some experiments have shown that a spun penny can land tails side up around 80% of the time, due to the heavier heads side tending to fall towards the bottom.
What side is heavier on a coin?
While the classic coin-flip game might seem like a 50/50 shot, studies in the US have found that the head side of a coin is slightly heavier, thanks to the symbol being larger.
Which side of a coin has more weight?
I can help with that. Because of the way most coins are made, the “heads” side can weigh more, which means it will fall on that side, leaving the other side up more often. Further, some magicians will have coins that are shaved, giving more weight to one side.

While just over 50% seems insignificant, the researchers said their findings are “overwhelming evidence for a same-side bias.” So, if the coin starts heads up, it’s more likely it will land heads up, and vice versa. Frantisek Bartos, lead author of the study and a psychological methods Ph.
What comes up more often, heads or tails?
I can help with that. When a coin is flipped 1,000 times, it landed on heads 543 times out of 1,000 or 54.3% of the time. This represents the concept of relative frequency. The more you flip a coin, the closer you will be towards landing on heads 50% – or half – of the time.
