For the heights of Sonic, Tails, Knuckles, Doctor Eggman, Metal Sonic, Amy Rose, Cream the Rabbit, Big the Cat, Silver the Hedgehog, and Blaze the Cat, were revealed by Sonic Fandom Wiki.

On the other hand, Sonic X Fandom Wiki disclosed Maria Robotnik’s height.

We based Vanilla the Rabbit’s height on how tall she stands beside her daughter, Cream the Rabbit. According to Cream’s profile in Sonic Fandom Wiki, she has an official height of 2 feet and 3 inches.

In Sonic X, Vanilla appears to be a head taller than her daughter. Hence, we estimated that Vanilla is 2 feet and 9 inches tall.

Moving on to the Commander, we have found footage from YouTuber Spaghetti King that shows his appearance in Shadow the Hedgehog game. Since Shadow has an official height, we used it as a basis to determine how tall the Commander is.

In the scene where the Commander confronted Shadow, the hedgehog only reaches Commander’s waist. We have read from the Sonic Fandom Wiki that Shadow stands at 3 feet and 3 inches.

With that, we approximated that the Commander is 5 feet and 11 inches tall.

Next, in a scene from Shadow the Hedgehog game, we notice that the President appears to be two inches shorter than the Commander. Thus, we arrived at an estimation that the President is 5 feet and 9 inches tall.

As for Sinbad the Sailor, since he is Knuckles’ counterpart, we believe that he is of the same height as him.

Now, let’s discuss Doc Ginger’s height. We have watched a Sonic Boom: Rise of Lyric gameplay by YouTuber jullMs and observed that Doc Ginger is of the same height as Amy Rose.

Therefore, we estimated that Doc Ginger is 2 feet and 11 inches tall.

In the Sonic Boom game, Sonic and his friends’ interaction with Salty made us determine the Hippopotamus’ height. It appears that Tails’ 2 feet and 7 inches frame reaches Salty’s waist. Therefore, we approximated that Salty is 5 feet and 4 inches tall.

On the other hand, Amy Rose’s interaction with Foreman Fred helped determine his height. Based on our observation, Foreman Fred is half a head taller than Amy Rose, making him 3 feet and 4 inches tall.

Lastly, Perci is half a head taller than Sonic in the game.


In terms of age, the Sonic Fandom Wiki revealed the age of Sonic, Tails, Knuckles, Amy Rose, Cream the Rabbit, Big the Cat, Silver the Hedgehog, and Blaze the Cat.

Though Dr. Eggman’s age was not disclosed, we determined his age based on appearance and personality. Hence, he appears to be in his 60s.

As for Metal Sonic, we have read from the Character Profile Wikia that he was created five years ago. Therefore, we used this as his age.

Moving on to Vanilla’s height, we estimated that she is 30 years old due to her personality and appearance.

As for the Commander’s age, he stated that he had been close with Maria Robotnik since childhood. According to Sonic X Fandom Wiki, Maria was 12 years old when she died. 

In the game, the Commander appears to be half Maria’s age. It’s been 50 years since Maria died, so if we add the numbers, Commander could be 56 years old.

Next, we estimated that the President is in his early 50s. In his appearance in Shadow the Hedgehog game, he looks like he is younger than the Commander.

Speaking of Maria Robotnik, we had stated earlier that she was 12 years old when she died, and it’s been 50 years since her death. If she could be alive, her age would be 62 years old.

Now, for Sinbad the Sailor, since he is Knuckles’ counterpart, Sinbad could be 16 years old like him.

For Doc Ginger’s age, we have estimated that she is 60 years old. Based on her appearance in the Sonic Boom game, her voice and appearance show traces of her possible age.

Now, for Salty and Foreman Fred’s ages, we observed that Salty is older than Fred. We determined them based on their personality and appearance.

Last but not least, we estimated that Perci is close in age to Sonic and his friends. She is probably a young adult based on her character and actions.


The BMI Chart is the basis of the estimated weights of the Sonic the Hedgehog Characters. Furthermore, it depends on their heights and ages.

Firstly, Sonic the Hedgehog, Silver the Hedgehog, and Perci have the same approximate weight which is 30 lbs.

Secondly, Miles “Tails” Prower, Amy Rose, Vanilla the Rabbit, and Doc Ginger are estimated to weigh 20 lbs.

Next, Knuckles the Echidna, Sinbad the Sailor, and Foreman Fred are weighing 35 lbs approximately.

Then, Metal Sonic, and Blaze the Cat are estimated to weigh 25 lbs.

Also, Doctor Eggman, Commander, the President and Salty are estimated to weigh 320 lbs, 300 lbs, 295 lbs, and 235 lbs, respectively.

Lastly, Big the Cat, Maria Robotnik, and Cream the Rabbit are approximated to weigh 160 lbs, 70 lbs, and 15 lbs, respectively.
