How Tall Are the '7 Little Johnstons,' Exactly? The Family's Heights, Explored

When 7 Little Johnstons premiered in March 2015, TLC viewers quickly fell in love with the family made up entirely of little people. The series stars Trent and Amber Johnston and their five children — two biological and three adopted — as they navigate life with achondroplasia dwarfism.

Over the course of 13 seasons, fans have learned the Johnstons can do pretty much anything a person of average height can do, just with some modifications. Still, many have often wondered: How tall are all the members of the 7 Little Johnstons family, exactly?

A number of online sources report that Amber Johnston is roughly 4 feet tall, while Trent is 4 feet 3 inches tall.

Jonah Johnston is reportedly 4 feet 4 inches tall — and since Elizabeth Johnston appears to be the tallest in her family, she is likely 4 feet, 5 inches tall.

Anna and Emma are fairly close in height and all slightly taller than their mom. So we would estimate them to be roughly 4 feet, 2 inches tall. Meanwhile, Alex is about the same height as Trent at 4 feet, 3 inches tall.

In general, the Johnstons don't often talk about specific numbers when it comes to their height. However, in a Season 11 episode of 7 Little Johnstons, Trent and Amber were trying to figure out how tall their soon-to-be exchange student from Finland was, based on photographs.

"So I'm looking at this picture right here, and he appears to be an average-sized achondroplasia," Trent said to his wife, who looked a little confused. "Average height is between 4' and 4'5". Amber clarified that the range for little people is a bit broader, more like from 3'6" to 4'10".

Trent then compared Joose to the height of a handrail in a photo, which he thought was about 36 inches tall. He came to the conclusion that Joose is roughly as tall as Amber and Trent.

"You don't know!" Amber insisted. "How do you know how tall his family is?"

While video-chatting with 17-year-old Joose for the first time later in the episode, the Johnstons asked him how tall he was. He explained that he's 114 centimeters, which is about 3 feet, 9 inches tall. The Johnstons compared that height to that of Jonah's girlfriend, Ashley, who is a bit shorter than their family members.

"I was saying that he was between 4' and 4'5", so my forensics were just a little bit off — by 8 or 9 inches," Trent admitted.

Amber replied, shaking her head, "I think you just need to keep your day job."

During the video chat, Joose also showed them the scar on his arms from his lengthening surgery, which has helped him reach things more easily in his everyday life.

"Lengthening surgeries are controversial when it comes to an individual wanting to have them to just gain height for aesthetic purposes," Amber explained to the camera. "When someone is undergoing the upper arm lengthening surgery to be able to reach the steering wheel or to be able to reach their body parts, that is a whole different story. Because that is benefitting the individual in daily life functions."

That's when Trent pointed out, "Genetically, no matter how long you make your legs or how long you make your arms, you're still a little person."

Height aside, we can't wait to see what the Johnstons have been up to in Season 13.
