**EXPLANATION OF SPONGEBOB SQUAREPANTS CHARACTERS’ HEIGHTS**

Since SpongeBob’s height was revealed, we estimated the other characters’ heights based on how tall they were when placed beside him.

But to make things easier, we also used the estimated heights of other characters to determine how tall the remaining characters were.

We used Season 2’s characters’ model sheet from the SpongeBob SquarePants Fandom Wiki to estimate the heights properly.

According to SpongeBob’s driver’s license, he is 4 inches tall or 10.2 centimeters. If he is placed beside Patrick, he is a head shorter than him. This makes Patrick 12 centimeters tall.

Next, Squidward appears to be a few centimeters taller than Patrick. Hence, we arrived at a height estimation of 12.5 centimeters.

On the other hand, Mr. Krabs is as tall as Patrick.

For Mr. Krab’s nemesis, Plankton only reaches his limbs. With that, we estimated that Plankton is 1 centimeter tall.

As for Gary’s height, since he only reaches SpongeBob’s shoulders, we approximated that Gary bears an 8 centimeters height.

Since SpongeBob is only at Sandy’s eye level, we supposed she has an 11 centimeters frame.

If we place SpongeBob near Karen, he only reaches her shoulders. Therefore, she could be a 12-centimeter-robot.

Moving on to Mrs. Puff, she is shorter than Mr. Krabs and Patrick; hence, she might bear an 11.5 centimeters height.

For Pearl’s height, she appears to be a few centimeters taller than Squidward. With this, we estimated that she is around 13 centimeters tall.

Moving on to Larry’s height, SpongeBob only reaches his lower chest. So, he could be around 15 centimeters tall.

Lastly, let’s discuss the heights of the retired superheroes Mermaid Man and Barnacle Boy.

We estimated that Mermaid Man is 11.5 centimeters tall since SpongeBob is only on his chest level.

Then, Barnacle Boy is half a head taller than Mermaid Man.

**EXPLANATION OF SPONGEBOB SQUAREPANTS CHARACTERS’ AGES**

For SpongeBob’s age, we will once again use the information stated in his driver’s license.

Though there is no clear information about the SpongeBob SquarePants series’s timeline, we will use the dates where the ongoing season is set.

The latest episodes of Season 13 are released in 2022. Thus, we will subtract SpongeBob’s birthday from the aforementioned year.

Based on his driver’s license, he was born in 1986. With that, we can say that SpongeBob is currently 36 years old.

For Patrick’s age, we have read from the SpongeBob SquarePants Fandom Wiki that he and SpongeBob have been friends since they were babies.

With that being said, we estimated that Patrick and SpongeBob are of the same age.

Moving on to Squidward’s age, we estimated that he is 40 years old based on his personality and demeanor.

Also, he has been Pearl’s babysitter since she was a baby. Thus this clue justifies his age.

For Mr. Krabs’s age, we calculated that his current age is 80 years old since he was born in 1942.

According to the SpongeBob Bible of 1997, his Plankton was born in 1961. Hence, we calculated that he is 61 years old.

We estimated Gary’s age based on his appearance at Camp Coral. He appears to be around two years old, while SpongeBob is canonically ten years old.

With that, there could be an 8-year age gap between them. Thus, we arrived at a calculation that Gary is 28 years old.

Next, Sandy appears to be older than Patrick and SpongeBob. Especially with the maturity she displays.

That said, we suppose that she is 37 years old.

Moving on to Karen’s age, she could be younger than Plankton since he is her creator.

Probably, Plankton created her in his early 20s since the SpongeBob SquarePants Fandom Wiki revealed that Plankton dated Karen when he was still in school.

For Mrs. Puff’s age, we estimated that she’s 65 years old since she founded the first-ever underwater driving school before moving to Bikini Bottom and establishing her current driving school.

Now, for Pearl’s age, we suppose that she is 18 years old. We arrived at this estimation since, in the series, she is a high school student who appears to be in her senior year.

According to USAHello, most high schoolers in the United States are 17 to 18 years old.

As for Larry, we estimated that he is 38 years old based on his appearance and attitude.

Lastly, Mermaid Man could be 73 years old since Barnacle Boy is 68. Even in their younger years, Mermaid Man appears to be older than Barnacle Boy.

Additionally, Mermaid Man has displayed signs of his age, especially being forgetful. On the other hand, Barnacle Boy seems to remain sharper than him.
